Consider everyone’s future N

ative logging has been banned in Western Australia and Victoria and NSW will possibly follow suit.

There’s a lot to consider in that single sentence, but as always, it’s a not a simple situation.

While NSW hasn’t yet set a time for outlawing native logging, there’s a fair controversy brewing over a proposed Great Koala National Park in that state.

The park could well qualify as a litmus test to direct government thought on further action.

The thing is, the ‘park’ will extend from the Clarence Valley in the Northern Rivers region through to south of Coffs Harbour. Not only is that a huge chunk of the state, it’s an area where generations of timber cutters have made livings and carved out a slice of colonial history, and where

4

THE AUSTRALIAN ARBOR AGE

Good management can mean a bright future for everyone: forests, industry and koalas.

selective harvesting of hardwood is still allowed and supporting a sizeable forestry industry.

Details on how the park will work and its exact boundaries haven’t been made available yet, but it’s understandably a matter which needs to be managed with great care. Of course everyone wants our furry koala chums to survive and flourish, but what about the forestry professionals – some of whom seem to be similarly furry – and industries in the area? Don’t they deserve a future?

I don’t know what the answer is, and of course my opinion won’t be called for, but I hope all sides have the foresight to involve arboriculturalists in the discussions, and to take their advice into account. Sensible management, rather than decisions made on

generalisations and statistics, could well see healthier forests, increasing koala populations and growing timber industries.

Wouldn’t that be a great result?

We should all be watching closely.

Meanwhile, there’s some really topnotch material in this issue, as always, but I’m especially thrilled to welcome a new contributor, Alex Kalivadova.

Alex’s writing is both entertaining and well-informed, and I hope her views will spark some thought and discussion among The Australian Arbor Age readership.

It certainly had me taking a wider view on several issues.

Best get on with it. You start reading this one, and I’ll make a start on the April/May magazine.

A

lot of Australians would never have seen Acacia peuce, known as ‘Waddy wattle’ among other things. It grows in three distinct locations in the deserts of central Australia.

The tree is found in open, arid plains that usually receive less than 150mm of rain each year, and typically grows on shallow sand aprons overlaying gibber or clay slopes and plains, and between longitudinal dunes or between often dry watercourses.

The wood of the Waddy wattle is

extremely hard and dense, with dark, purple-coloured heartwood, and the trunk and branches are covered with a fibrous grey-brown bark. Flowers are a pale-yellow colour and appear in autumn and spring, usually following heavy rain events, and following flowering the species forms long, flat, pods with a papery texture containing large, flat seeds.

It’s a very slow-growing species and can live up to 200 years. Sapling and juvenile trees have a conifer-like look and can take up to three years to reach a

height of one metre. Some individuals are estimated to live over 500 years.

Although the Waddy wattle looks to favour an inhospitable environment, the tree is often host to various butterflies and their larvae, and also offers perches and nesting sites for birds, from grey falcons to desert finches. The foliage is often chewed by insects, and saplings were eaten by grazers such as cattle. Pioneering farmers were reported to use the tree to make highly durable and termiteresistant fenceposts.

New Treemme X series tool-carrier tractors For operators who need multi-purpose and high-performance machines that are easy to use but are not afraid of demanding work, Merlo offers the new Treemme X series.

T

reemme X machines – MM 250X (8T) and MM350X (9.2T) – are designed primarily for use in forestry, silviculture and soil preparation. The wide range of attachments available, the exclusive 360° visibility and the incredible manoeuvrability make them the ideal for professionals looking for specialised machines with the following features: • Front and rear hydraulic handler (optional equipment)

14

THE AUSTRALIAN ARBOR AGE

• Continuous hydraulic delivery to the front attachment • Six-cylinder engines with power ratings up to 250kW (340hp) in line with Stage V emission standards • Hydrostatic transmission with electronic control, maximum speed 40kph • Permanent four-wheel drive and allwheel steering with three available modes plus one option

• Cab compliant with ROPS, FOPS and OPS with approved anti-shattering transparent windows, and • Service hydraulic system with loadsensing pump.

Technical advantages

The steel structure of Treemme tractors is the framework on which a highly technological working system is built.

The frame, reinforced with armouring

in the most exposed areas, intensifies the concept of sturdiness and resistance.

The result is a range of machines that are particularly efficient and robust in all applications.

Hydraulic activation offers countless competitive advantages over traditional systems using mechanical devices. The equipment in use can work in positions that go beyond the maximum angles allowed by the cardan shafts as there are no mechanical parts subject to breakage and, as a result, any recoil of the kinematic chain is excluded.

A further advantage: the operator can reverse the equipment’s rotation direction through a simple electrohydraulic control in the cab.

Many machines in one

Countless hydraulically operated devices available for the Treemme X series enable forest-maintenance operations to be effective and profitable. There are shredders for the construction and

maintenance of fire breaks and buffer zones for high-voltage power lines and gas pipelines. Systems are available for the reclamation of stony areas, extractors for removing plant roots after cutting, equipment for preparing the soil, soil reconditioners, and many other attachments, all rich in advanced technology.

All attachments can be equipped with quick-coupling hydraulic connectors.

The Vermeer Cutting System (VCS)

How innovative cutter-tip solutions improve stump grinder performance.

I

n the early 1950s, Gary Vermeer was facing a formidable foe: tree stumps.

Millions of them were entrenched in agricultural fields across the corn belt.

Gary was grinding his teeth in search of a better way to remove them. Anything but digging them out — a highly labourintensive process.

In 1957, a Vermeer test crew pitted a novel machine against that common adversary. The crew quickly discovered the best way to grind a tree stump was with a side-to-side cutting motion, sweeping across back and forth.

It was an innovation in tree care equipment — with the approach still driving modern stump grinder technology. And the desire to find solutions still drives product development at Vermeer today.

“Our testing methods are designed around solving a problem,” said Randy Runquist, manager of cutting-edge

16

THE AUSTRALIAN ARBOR AGE

research and development at Vermeer Corporation. “They are designed for a particular product.”

Once a new product is introduced, the enhancements never stop.

“Researching, refining and improving upon our high-quality products is part of the core culture at Vermeer. We are constantly looking for ways to improve every machine component to enhance our customers’ experience,” continued Runquist.

Continuous improvement drives stump grinder advancements

This focus on finding a better solution has led to continual advancements in the Vermeer stump grinder product line — right down to the grinder tips. Models ranging from 25hp to 74hp (18.6kW to 55.2kW) minimise the labour-intensive work of removing even the most challenging tree stumps.

An example of this continual improvement is the introduction of the Vermeer Cutting System (VCS), standard on most new Vermeer stump grinder models. One of the main challenges the research and development team wanted to solve was the tooth and bolt wear. This was an issue with many of the available stump-cutting systems.

“Torquing cutter teeth daily is pretty common for most stump grinder users.

Bolts that aren’t torqued properly tend to rotate in the pocket, causing premature wear and impacting the performance of the cutter wheel,” said Josh Vrieze, Vermeer senior product manager for Tree Care, Rental, Landscape. “The tooth design on the VCS has a mounting and retention structure that helps keep teeth from shifting while absorbing the shearing force, instead of the bolt securing the tooth to the cutter wheel while operating. This design makes it

possible to secure each set of teeth with a single long bolt and reduces the need for retorquing.”

The VCS design is another innovation for the tree care equipment industry. It features a single bolt for all VCS teeth and only two tooth-part numbers. Each tooth bolt has ease of access with either a torque wrench or impact wrench. No special tools or disassembly are needed for access to these bolts.

The VCS features two cutting edges, providing the operator maximised cutting performance. The design of the cutting system helps protect the bolt from the sheer force of the cutting action. The new V-profile of the carbide optimises cutting productivity and the industrial carbide material gains productivity at the stump.

The VCS retains the two-sided cutter design, but rather than rotate in the pocket, the tooth is flipped to the other side of the wheel to access the other cutting edge.

THE FUTURE OF CHIPPING BEGINS WITH MORBARK’S BVR BRUSH CHIPPERS The BVR line of brush chippers builds upon the legacy of Morbark’s innovation in the tree care industry through an updated modular design. The new configuration streamlines the equipment’s overall upkeep and maintenance routine, reducing customer downtime and increasing overall productivity.

The BVR brush chippers also feature Morbark’s proven and patented ZeroClutch®. Our ZeroClutch removes the anxiety of engaging the chipper drum, damaged drive belts, and burned clutch discs and elevates the customer’s operating experience. Customers will now simply start their brush chipper, throttle the machine to full RPMs, and engage the feed control bar.

The BVR brush chippers also feature a Reverse-Style Pivot Assembly, which contours the radius of the drum, reducing dead space between the feed wheel and the drum. This gives the machine a

mechanical advantage for increased down pressure, providing optimal chipping results when working with challenging materials.

Other notable innovations to the BVR line include: • Infeed-Mounted Control Panel - Provides a more convenient access location for operators • Side-Load Anvil - Four-sided, side-load anvil makes changing the anvil easier.

• 360-degree manual swivel discharge chute - Offers multiple locking positions for greater operator control over chip discharge, and a • 3-position Electronic Control Bar with Dual Safety Pull Cables, designed to keep safety a top priority while working on a jobsite.

ATC Land Management and Merlo/GMT

Melbourne-based ATC Land Management has taken a giant leap forward in productivity and safety – thanks to the acquisition of a Merlo Roto 50.26S telehandler and GMT050TTC grapple saw.

A

TC Land Management has been in the arbor industry for over 35 years, and offers services ranging from full tree and stump removal through to mulching, chipping, stump grinding, pruning, and arboricultural reports.

The company is based out of Essendon, Victoria, and works throughout the Melbourne metro area.

Owner/Director Tom Salt is a climber and a seasoned professional.

“While tree works can require a light touch, where possible we try and incorporate our heavy machinery to assist with our work,” Tom told us. “This not only reduces the time of man hours for the works, but also reduces the fatigue and increases worksite safety.”

It was this business strategy which led Tom to go looking for a suitable telehandler/grapple-saw outfit, and to end up with Australia’s first new Merlo Roto with GMT050TTC attachment.

ATC Land Management couldn’t be happier with the increased efficiency and safety the Merlo Roto 50.26S and GMT grapple saw have brought to its work sites.

Image: Merlo

Hard work

“We do a lot of clearing and storm damage…that kind of work,” Tom told us.

“With the Merlo and GMT we’re trying to utilise both being able to do the job safely and efficiently, and also to limit the need for outside trades, cranes and EWPs. We’re trying to streamline everything so we can do a bit more in-house.”

Shaun Pollard at Melbourne Tractors could see Tom was an excellent candidate to reap big benefits from Merlo and GMT equipment combo.

“Tom’s in tree-care management, and the two products, the Merlo and the GMT, work hand-in-hand,” said the cheerful sales manager.

“The Merlo weighs just over 17 tons. It’s a big machine with a lifting load capacity of five tons and a lifting height off its telescopic system of 25.9m. It also has a maximum reach at ground level of 22.9m.

“And this thing’s capable of getting into some really intricate areas.”

That’s clearly a big plus for any 24

THE AUSTRALIAN ARBOR AGE

forestry or arbor equipment, but Shaun, like Tom, could see some an even more important benefit.

“Safety,” said Shaun with a firm jaw and steely gaze. “Tom and his team

were doing jobs manually where they had ropes and they’d sling themselves up the tree with a chainsaw. He’s much safer from doing this work from inside the cab.”

A big step forward

And so far the equipment is doing everything expected of it.

“I was climbing and cutting for the crane, so I have a good understanding of what weights I’m taking,” explained Tom. “As long as you have that knowledge behind you, the rest’s fairly simple.

“There’s a few really good features on of Merlo/GMT rig. The stabilisers let me set up in some pretty cool spots where I couldn’t get a crane, and it still has good capacity to do what I wanted and needed it to do.” “‘Roto’ in the name means it offers continuous rotation on the top of the operating station for that machine,” chimed in Shaun. “Tom can continuously turn 360° on a turntable and get in to some really tight spaces, and he has the ability to park the machine in a safe area, or in a tight-spaced area, and then reach and lift to height to work with that GMT grapple saw to bring down branches and heavy bits and pieces safely.”

“That’s probably the biggest thing, I think.”

The best bit

With big increases in efficiency and safety the machinery has already proven a total winner, Tom pointing out with satisfaction the rig, “…massively reduced our risk. That was the main thing.”

Fecon Australia the key to success

Victorian-based Bushfire Mitigation & Land Services prides itself on leaving the minimum environmental footprint, and credits Fecon products with helping achieve that goal.

Growth

Bushfire Mitigation & Land Services hasn't looked back since the move to Fecon equipment. Image: Fecon Bushfire Mitigation & Land Services is a family owned and operated business specialising in preparing private property and public land to reduce the impact of fire, and to recover from both fire and severe storm events.

Based in Victoria, services offered by the company include mulching and mowing, planned burn preparation, weed management, chainsaw operations, property and fence line clearing, rural fencing, fire break and emergency track clearing, construction, stump grinding with minimal ground disturbance, storm recovery works, and vegetation rehabilitation.

Owner Edan Brennan has over 15 years’ extensive experience working in the prevention and suppression of bushfires and on the frontline fighting some of the most significant fires in Victoria and NSW for both government and volunteer agencies. With the commencement of the business they went looking for new specialised equipment that could assist in the mitigation of vegetation hazards.

The Fecon difference

“We identified a need for a stump grinder that could efficiently

grind stumps with minimal ground disturbance,” explains Edan.

“But we needed a grinder to operate more safely than other products we saw currently on the market.”

After a thorough search of available equipment and watching that equipment in action on YouTube, Edan’s crew found its way to the Fecon website, which allowed a comparison of specifications and operations. It also displayed videos of the equipment in use, which was very helpful.

“After completing our research, we saw Fecon was offering equipment that met our needs,” says Edan.

Personal touch

Edan’s final decision to run with Fecon products came down to the machinery conforming to his company’s ideals, the quality of the product, and value for investment. But meeting Fecon Business Development Manager Jake Langdon was another big contributing factor.

“The service from Jake was outstanding,” Edan remembered. “He didn’t pressure us to purchase, and his professionalism was next level. We felt supported, well informed, and knew purchasing through Fecon Australia was the right option for our business.”

Following the success of the stump grinder, Edan and his team researched the Fecon standardflow mulcher, which also met the company’s requirements and allowed work in more confined spaces.

“The mulcher fitting to a smaller machine meant we were able to meet our environmental goals,” Edan points out, “and we’re able to mulch fine fuels to mitigate bushfire risk.”

Adding the Fecon equipment to the Bushfire Mitigation & Land Services fleet allowed offering much-needed grinding and mulching services, and Edan’s business grew as a result.

The company now offers a broader range of fire-mitigation services with an eye firmly fixed on the company’s environmental goals.

A good decision

Bushfire Mitigation & Land Services hasn’t looked back since the move to Fecon equipment allowed an increase in services offered to customers, and Edan is looking to further expansion and a bright future for the company.

“Our work in stump grinding has seen us grind in excess of 2000 stumps along forestry roads, providing a clear path for future maintenance of the roadside vegetation,” he said.

“And the ability to mulch fine fuels in environmentally sensitive areas means we’re able to reduce the risk of bushfires to local communities.

“The ability to run both pieces of equipment from a smaller machine has enabled us to operate with a minimal footprint, and reducing the impact on the ground guarantees the preservation of native flora and fauna, safeguarding our environment for future generations.”

Streamlining the daily grind

Bryce Adamson from New South Wales-based BKA Earthworx has just levelled up his forestry game with the new Cat® 299D3XE Land Management package. Find out what made it the perfect choice for his growing business.

I

f you’d told Bryce Adamson just a few years ago that he’d be making a living using smaller machines like compact track loaders, he would have laughed at you.

But that’s just how the chips have fallen for his business, BKA Earthworx, since he started it in 2020. The trained plant mechanic trusted his business sense, followed his nose, and it led him into forestry and land management.

“I’d always envisioned running a fleet of dozers and large excavators – which we still do dabble in – but it’s nowhere near as busy as our smaller gear,” Bryce says.

“Around 90 per cent of our work now is vegetation management, slashing

28

THE AUSTRALIAN ARBOR AGE

or mulching using our compact track loaders. There seems to be a growing market for this kind of work, as opposed to the traditional methods of sending in a dozer and making a big messy pile of things to burn in the winter.

“Focusing on mulching has been a huge success for us so far.”

Mulching with mates

Bryce is joined under the BKA Earthworx banner by Matt Fisher, a skilled operator, and Bryce’s close mate of more than 20 years. Bryce says Matt has been crucial to the growth of the business from the start.

“I don’t really look at Matt as an employee,” Bryce says. “He’s just my best

mate, who I’m lucky enough to liaise with every day, and who I know I can trust and grow the business with. I don’t think I would have been able to handle that with someone I didn’t know.”

Bryce says an average day on the job for him involves contacting clients, organising jobs, and then touching base with Matt to get mulching. He says a big focus for him – and he suspects a big factor in the success of the business to date – is making the effort to develop personal connections with customers, and establish strong foundations of trust.

“It’s surprising to hear people’s experiences with contractors not following up on quotes, or not showing

up when they’ve said they will,” Bryce says. “We’ve always aimed to be committed to our clients, communicate well, and be up front and honest every step of the way.

“Making people feel heard, listening to their needs, and then delivering what they’ve asked for goes a long way. And that’s made so much easier with quality gear and no breakdowns.”

Made for it

The latest piece of quality gear that Bryce is referring to is a newly delivered Cat 299D3XE Land Management package

BKA Earthworx takes advantage of WesTrac’s FitFleet Customer Value Agreement to manage the maintenance of its Cat equipment.

Image: Prime Creative – a specifically tailored combination of a Cat 299D3XE Compact Track Loader and a Cat HM418 Mulcher.

Building on the success of a smaller Cat 289D3 Compact Track Loader that BKA took delivery of earlier in 2023, Bryce says his and Matt’s volume of work started to demand something a bit bigger and more powerful.

“After looking at some of the competition on the market, I just couldn’t be swayed,” he says. “My experiences just kept bringing me back to Caterpillar, and the 299D3XE Land Management just ticked every box and more.

“It just offered everything we needed in one package. Plus, the way the tool is combined with the machine – it’s tuned perfectly.”

According to Nina Zeidan, WesTrac Product Advisor for Cat Attachments, Bryce opted for the HM418 Mulcher because of its Bite Limiter technology.

“The advantage when using a Bite Limiter mulcher over standard carbide mulchers is the ability to cut and mulch material in a single pass rather than the initial cut with the front door open, then reversing over the material with door closed to break it down further for a neater finish,” she says.

The Cat 299D3XE Compact Track Loader and the Cat HM418 Mulcher’s hydraulics are tuned for hasslefree plug-and-play operation. Image: Prime Creative

“While the daily maintenance and sharpening is a bit more involved than with a standard carbide tooth mulcher, Bite Limiter mulchers are used by professional forestry operators who understand that, like a butcher or a barber, sharp tools are what enable them to provide an expertly finished product on the first cut.”

Bryce says having the machine and attachment interact seamlessly is a big win for ease-of-use, and streamlines the process of switching attachments – especially for any contractor with multiple operators on the tools.

“It’s one less thing to have to run your

The productivity gains offered by the Cat 299D3XE Land Management gives Bryce more time to focus on doing his work and running business. Image: Prime Creative operators through, because there’s only one way it can be hooked up,” he says. “With this mulcher, you just hook every single hose into the machine, and it knows what to do as soon as you switch it on. It detects that it’s a highflow attachment and engages high-flow automatically.

“So, there’s no worrying about whether you’ve got the right flow rate for the unit. It makes it a no-brainer to go with Cat attachments and Cat machines – it just takes all the guesswork out.”

According to Joel Newton, WesTrac

Sales Representative for Building Construction Products in the Newcastle and Hunter Valley region, this is just one of the reasons the package was the perfect choice for BKA Earthworx.

“Having the mulcher specifically tuned to the hydraulic output of the Cat 299D3XE is big for maximising productivity,” he says. “It’s also equipped with a hydraulic oil cooler, reversing fan, and a range of seals and guards that make it perfectly suited to Bryce’s application.

“The sealed and pressurised cab also keeps the operator cool, comfortable,

Bryce says there is a growing market for mulching services, rather than ‘traditional’ vegetation management practices using larger machinery.

Image: Prime Creative 32

THE AUSTRALIAN ARBOR AGE

and in a quiet working environment for long days in harsh conditions in applications such as mulching.”

Bryce can attest to how tiring a day of vegetation management under the Australian sun can be, but he says arming yourself with the right tools goes a long way.

“For any operator sitting in a cab all day long, it can be really fatiguing,” he says. “But the Cat machines offer a really great cab layout – everything is very simple to use, and it’s extremely comfortably to sit in for long hours.”

The Cat 299D3XE Land Management ticks every box for BKA Earthworx.

Image: Prime Creative

Peace of mind

Joel says Bryce is a great example of a customer who has made the move to Cat equipment based on the quality of the product, and stayed for the support on offer.

“We’ve found customers like Bryce will generally come back to buy their second and third machines due to the after-sales support you get at WesTrac,” Joel says. “This can consist of our FitFleet Customer Value Agreements for service, 24-hour parts ordering and availability, which combines to allow Bryce to focus on running his business and doing the work.”

Bryce says the added peace of mind this backup service provides is almost as valuable as the machinery itself.

“Coming from a maintenance background, I’m probably a little bit finicky and fussy about certain things, so I’ve previously done the majority of the maintenance on my own equipment,” he says. “But I can’t be in seven different places at once, so handing the maintenance side of things over to WesTrac with our FitFleet agreement has made life so much easier. When the agreed service interval comes around, they just call, ask when the machine’s available, and get it sorted.”

Pairing Cat machinery with Cat attachments is a ‘no brainer’, according to Bryce.

Image: Prime Creative

Stress-free parts ordering

Bryce sings a similar tune when it comes to ordering spare parts through the WesTrac web portal.

“When I’m at work all day long, I don’t have the time to stress about ordering parts,” he says. “Often, you’re expected to jump on the phone during business hours – just another phone call I have to remember to make. But for Cat parts – say, something simple like teeth for the mulcher – I can jump onto my WesTrac Parts.cat.com account from any device, at any time of the day, and order the parts, and I know they’ll turn up and a couple of days’ time.

Bryce says his experience of having smart, reliable machinery paired with comprehensive support from WesTrac has the BKA Earthworx team already pondering its next piece of Cat gear.

“As a business owner, you have a million things to remember every day,” he says. “And the teams at Caterpillar and WesTrac make things a whole lot easier for me. They really do offer the full package.”

Joel says the Cat 299D3XE Land Management was the perfect choice for the tough conditions the BKA Earthworx team faces every day.

Battery chainsaws

With a compact and well-balanced design, both models are easy to handle in awkward or outstretched positions. Image: Stihl

STIHL’s most powerful tophandle battery chainsaws The STIHL MSA 220 T is the most powerful battery top-handle chainsaw in the STIHL range, designed exclusively for professional use by trained arborists.

023 saw the introduction of a brand new battery chainsaw capable of the most demanding jobs in tree work.

The new STIHL MSA 220 T is a fantastic alternative to the MS 201 TC-M petrol chainsaw, and is more than capable of cutting large branches and making reduction cuts across the tree canopy.

Added features

Launching in Autumn 2024 is the MSA 220 TC-O, the same high-powered battery top-handle chainsaw which now features an oil sensor on an LED display.

This innovative new added feature gives the user a warning when the chain oil level is low.

in awkward or outstretched positions.

The intuitive trigger lockout system is simple to use, and the electronic unlock button is within easy reach of the thumb. The status LED will light up green when the chainsaw is ready for use, and the chain brake LED will light up red when the chain brake is engaged, so you can easily see when the tool is good to go. Both models also feature an adjustable oil pump, allowing you to customise the oil output to match the application or guide-bar length at hand.

Battery power

Just like the MS 201 TC-M, the MSA 220 T and the MSA 220 TC-O each have a sprocket cover with captive nut, easy to use side chain tensioner, and a black felling line for making accurate cuts.

Paired with the AP 300 S battery and the NEW 3/8 PS3 Pro chain, their output is comparable to the 201’s power output too.

Both models are recommended for use with the AP 300 S battery, however, the new STIHL AP 500 S battery will the extend the working time further.

Image: Stihl 300 batteries as this will reduce both the runtime and the performance. The AP 300 S can be fully charged in 45 minutes with the STIHL AL 500 quick charger and

will give up to 29 minutes of working time depending on what’s being cut and how it’s used.

Professional choice

The motor and electronic components are air-cooled and protected from dirt by an easily accessible fleece air filter. The filter needs to be cleaned regularly to prevent heat build-up – to do this STIHL recommends STIHL VarioClean, the cleaning agent specifically designed for the task. Spray on both sides of the filter, leave for 10 minutes, then rinse gently with water and leave to dry.

Like all models in STIHL’s AP Battery System, the MSA 220 T and the MSA 220 TC-O are compatible with the STIHL Smart Connector which will record the working time of the tool and transmit the data to the Connected App via Bluetooth. This means you’ll know exactly when to complete certain maintenance tasks (such as cleaning the air filter or dressing the guide bar) and have an accurate record of exactly how much work the tool has done.

Top-handle chainsaws should only be bought and used by trained arborists and should never be used for cutting at ground level.

D

iversity in planting was once desirable, but not always achievable. Now it’s almost a necessity.

I’m talking about streetscapes of course, in particular street trees.

Many Local Government Areas (LGAs) in the past 20 to 30 years have moved away from mass planting of a single species for several reasons, one of the biggest being pest and disease management.

A good example of a species used for mass planting throughout Perth CBD and the surrounding suburbs is Platanus acerifolia. With the ability to tolerate a wide range of edaphic factors, the London Plane Tree thrives in the centre of busy cities where pollution is at its highest, pavement widths are at their narrowest, and consequently, treeplanting space is at a premium.

Yet still they thrive.

Investing more time in growing the trees in-ground (field grown) to allow natural root formation.

Ellenby Tree Farm

With the advent of the Polyphagous Shot Hole Borer (PSHB), and the avenues of closely planted, maturing trees, the ever-present threat of the spread of the borer from one tree to another is of real concern. Although regular infections of the Anthracnose fungus (Apiognomonia veneta) have been managed by good cultural practices, or in severe infections by administering a fungicide, PSHB is a different story. Diversity in planting will be another management strategy.

With these challenges in mind I spoke with Craig Woodroffe, co-owner of Ellenby Tree Farm, one of Perth’s largest tree-production nurseries.

Craig’s father David, an avid horticulturist working in Canberra at the time, started Ellenby Tree Farm back in the 1980s after deciding to relocate to Perth. Being actively involved in the 40

horticulture industry, he realised the offering of trees in Western Australia at that time was very limited. Craig recalls most of the trees they imported were from Victoria, a far cry from today where they selectively choose what they grow from their extensive tree gene pool.

‘Growing tomorrow’s tree today!’ is the company’s tag line.

Originally in Gnangara in Perth’s north – which is now the sales nursery – Ellenby Tree Farm has a 70-acre production nursery with more than 60,000 trees in Bullsbrook, northeast of Perth. Growing over 400 species ranging in size from 45 litres to mature transplants, Craig explained Ellenby is investing more time in growing the trees in-ground (field grown) to allow natural root formation, then using a variety of mechanical tree spades to lift them.

Consequently, a better-quality tree that is less prone to root girdling, or roots being rootbound after growing in the confines of a pot. I asked if there were any memorable projects. “Many!” was his enthusiastic answer.

“One that we were recently involved with was the new Karrinyup Shopping Centre,” Craig recalled. “We lifted in two Caesalpinia ferrara, Gleditsia sunburst and shademaster, Fraxinus raywoodii, Calodendrum capense, and two Delonix regia, all advanced trees, and they’re all doing really well.

I asked Craig what challenges Ellenby was facing.

“Lack of sawdust and pinebark used as part of the growing medium for the trees is becoming a problem,” he outlined. “It’s getting harder to source, and predicting future trends in trees is always a 42

challenge, but the Agonis varieties, Angophora costata, and Cupaniopsis anacardioides, are always a favourite with councils.

Options

Celtis australis and Occidentalis are popular, but can become heavily infested by a variety of Psyllid insects.

Trees on narrow verges that have a large canopy overhanging the road, and have residents parking their cars underneath for shade, often end up with the sticky honeydew residue splattered all over their windscreens and roofs – honeydew being the substance excreted by the Psyllid after enjoying a healthy chlorophyll meal. Depending on the extent of the infestation, the type of pest, and the size of the tree, there are several options available to the arborist.

The time of applying the product is critical in the life cycle of the offending critter. Consideration must also be given to the beneficial insects or natural predators the product may effect.

For small trees you may be able to use a foliar spray – wind and location permitting. Soil drenches are noninvasive, but require a larger area to administer. It would have minimal effect trying to soak a tree’s root system in a one-square-metre tree well.

The other option is more invasive and involves drilling into the tree and using a systemic insecticide.

Drilling a series of holes around the tree’s trunk, usually staggered, and drilled vertically down, obviously creates a wound in the tree and a potential entry point for any harmful pathogens. Any pruning cut, wound or

breaking through the outer bark and into the cambium breaks through the anoxic seal.

Once the insecticide is administered, usually by syringe, the hole must be sealed. As with any type of systemic injection, it is critical to follow the manufacturer’s recommendations.

Ellenby Tree Farm uses a variety Image of tree spades to supply a better quality tree.

Soil health is crucial

Soil health plays an increasingly important role in helping the tree combat disease and disorders. The soil provides crucial elements to nourish the tree. Arborists are becoming more acquainted with soil biology, another part of the tree jigsaw.

Identifying beneficial microbes, such as nematodes, protozoa, fungi, and bacteria – all part of the soil food web – helps identify what may be contributing to tree health and decline. An increasing number of Perth arborists are purchasing microscopes.

Chemical analysis is a little more specialised, and expertise in this field is typically sought by a qualified agronomist.

A good friend who works in broadacre farming once made the statement, “Trees outsource their stomachs to the soil.” It’s an interesting concept. Several Perth municipalities have recommended various soils to be used in residential planting and attached to a development application (DA).

Good urban management

The City of Gosnells, a south-eastern region of metropolitan Perth, has a population just shy of 130,000 and covers an area of 128 square kilometres. The region has history, and was originally purchased by Charles Gosnell, back in 1903, mainly for its fertile soil. The owner was part of John Gosnell & Co, a London based cosmetic company, who saw value in planting aromatic flowers in the rich soil.

I asked the city council’s CEO, Ian Cowie, if the city was moving towards greater diversity in its tree-planting schedule.

“The city plants a wide variety of native and exotic species,” he responded, “with selection determined by location, available soil volume and proximity to infrastructure or environmentally sensitive areas.

“The species of trees available for

planting are reviewed biennially and all efforts are made to plant the largest variety of appropriate trees.

“Recently, the city has placed more emphasis on planting larger endemic trees to support local fauna, such as Black Cockatoo populations, particularly in areas such as the city’s parks and reserves.”

I enquired whether the city grew any of its own stock.

“The city sources its tree stock from commercial nurseries,” replied Ian. “Some of these vendors offer the ability to grow stock specifically for the city’s requirements.”

What challenges does the council face in the urban landscape, given the declining rainfall, and drying climate?

“Increasing density has resulted in smaller planting spaces in newly

developed suburban streets,” outlined Ian, “often with infrastructure in close proximity, which has limited the city’s street tree-planting options.

“Another challenge has been providing water to newly planted trees in a drying climate. The city has extended its watering season in response to this.”

What are the council’s predictions for trees in Gosnells?

“The city recently adopted Greening Gosnells: Our Public Tree Strategy 2022-2030, provides the city with a clear direction for managing public trees and sets targets for canopy cover and tree planting. It includes clear action plans for protecting our natural assets and increasing the number of trees in the public realm to ensure the City of Gosnells continues to be an attractive place.”

Association news

30 years of the TCAA

Jim McArdle looks back on the history of the Tree Contractors Association of Australia, the achievements of the presidents, and notes an upcoming change.

W

ith the 30th anniversary of the TCAA, the executive has initiated a new status within the peak body to include the term ‘arborists’.

To reflect a fairer version for the industry scope to move toward higher roles in Amenity Horticulture, the new name of the association is the Tree Contractors & Arborists Association Australia.

Besides people, trees are the most valuable resource contributing to green culture. Trees are also on the frontline of the environment and infrastructure development, and require more professional underpinning documentation supporting the tree-care industry.

The three key underpinning resources are: 1. The Australian Standards • (2009) Tree Protection in Development Sites • (2007) Pruning of Amenity trees • (2013) Raw Mulch Order • (2020) Treestock for Landscape Use. 2. Industry peer-produced documentation • Tree management guidelines, pre-

climb & proactive tree risk assessment • Code of practice • Hazard workbooks 3. Key organisations which constrain poor practice in the industry are: • Safe Work Australia • Fair work Australia • Councils • Courts (Land and Environment and civil), and • EPA.

Morena McArdle champions women in arboriculture.

The beginning

The TCAA was initiated in 1994 after storms ravaged most of the Australian coastline from 1992. The first meeting was held at Beacon Hill and a small committee was formed, including Murray Bolan and Mark Wilcox, who was elected president.

The membership numbers soon raced toward 300, with emergency work being included as a TCAA function.

Mark Wilcox, with assistance of the committee, initiated the TCAA as pillar of the industry to allow for consistency of rates and pricing. The schedule of rates allowed tree contractors fairer ways of tendering and engaging subcontractors

THE AUSTRALIAN ARBOR AGE

Dan McArdle, president from 2012 to 2015, secured unit crane access licensing for arborists. Image: TCAA on pre-agreed pricing.

The TCAA was never about monopolisation. It was about developing a consistent arborist who was qualified, reputable and supported.

Mark Wilcox: 1994-1997

Mark, the first president, established the beachhead of the TCAA so as to allow for fairer industry practice and more exposure for association members as a body of experienced, qualified, insured and referenced operators. No other body had been formed that was for the business leaders exclusively, and it was a win/win for consumers and government bodies alike. Rates and a level of professionalism were established.

Under Mark’s leadership the TCAA boomed, with privileged SES and insurance work flowing to 350 members.

The TCAA was about training and developing a consistent arborist who was qualified, reputable and supported. Image: TCAA Wilcox,” remembered third president, Ron Atkins.

“I took over that role around the mid 1990s. At the time, the association was actively pursuing local councils and insurance companies, with the intention of offering them fully qualified and insured members, well skilled and experienced in all manner of treemanagement operations. It was my task and desire to maintain the recognition the association had already achieved under Mark’s leadership.”

“During my tenure as President, with our hard-working committees, we were able to increase the TCA membership to supply prompt 24/7 attendance and service to leading insurance companies, councils and home owners in times of storms and tree failures, as well as constantly offering members selected

training programs, work operational reviews and more to ensure policies, procedures and operations were always up to date.”

Shiu Narayan: 2001-2011

Shiu Narayan increased the TCAA news and media representation and created a safety-at-work ‘one-stop shop’ for consultation and tree work.

His forestry background was significant in the development of policies directing better pruning practices and training, and he inaugurated the two underpinning standards of Pruning of Amenity Tree Service and Tree Protection on Development Sites.

Shiu also endorsed the Safe Work meetings to produce outcomes closely related to SWMS and JSA workbooks and auditing of the members.

Steve Tipton: 1998-1999

“My main focus was to get enough numbers together to make it worthwhile providing training courses for various activities which are now readily available,” said the TCAA’s second president, Steve Tipton, “Also networking and exchanging ideas and building bulk purchasing power as a group, and providing specialised services to SES and insurance companies to minimise untrained people being hurt.

“I think too many members looked upon The TCA as a cash cow in the provision of emergency services and that was the main purpose of their membership.”

Ron Atkins: 1999-2000

Dan McArdle: 2012-2015

Dan McArdle’s contributions to the progress of professional arboriculture are too numerous to list here, and have been substantial, but perhaps Dan’s biggest single legacy was securing the unit crane access licensing for arborists.

Implementing a licensing system in the Australian tree industry offers several benefits for both individuals and the industry as a whole.

While it might seem more convenient to operate without a licence, obtaining proper licensing in the Australian tree industry offers numerous advantages, including professional credibility, legal compliance, safety assurance, access to opportunities, and enhanced trust from clients. Additionally, it contributes to raising industry standards and promotes a safer and more professional working environment for everyone involved.

Regional Training was given to ensure TCAA business managers were qualified under AQF3 or AQF level 5 arborists.

Gregor Van Emrick: 2016-2017

Gregor has specialised regional knowledge that allowed for continued roles in bushfire management, windfarms and sustainable energy with regards to trees.

Gregor was an ex-TAFE arboricultural teacher and educated many arborists through the regional areas. Passing over his business, Agile Arbor, to his son Jaz allowed the family tradition to be inherent with high quality practices and vegetation-management programs.

Gregor would often cry out: “Where can I find another three arborists? Where can I find them?” His tenure began the recognition of there being a pressing lack of trained arborists in the being a problem for the industry.

Jim McArdle: 2018-2021

Reduced numbers of trained, qualified arborists continued as an issue during Jim’s presidency, and the TCAA endorsed the Training Package Review, bringing the peak bodies together and defining the role of the tree worker, climber and report writer, and risk assessor.

The TCAA was instrumental in providing training days and treemanagement guidelines to assist Facility 46

TAFE and government bodies, including mayors and ministers. Jim’s legacy was the production of the TMG-Tree management guidelines, the training of assessors, arboricultural articles, and allowing for best industry practice to evolve.

Membership increased prolifically

under his presidency, as did opportunities for school leavers and cross-skilled professionals joining the industry through correct training.

Carson Smith: 2022-current

As the current president, Carson’s overarching vision for the TCAAA extends far beyond mere membership growth. He’s dedicated to spearheading a movement that not only increases the membership, but revolutionises the arboriculture industry. Carson has also supported other states, sending arborists interstate to assist storm-damaged towns.

Carson’s primary aim is to elevate the standards of tree care across the nation.

The TCAAA vision

Through extensive advertising campaigns, strategic partnerships, and proactive outreach initiatives, the TCAAA will: • Attract more members, but also foster a community that prioritises

education, accreditation, and adherence to best industry practices.

• Expand its reach into diverse regions, collaborating with other tree guilds and associations to establish a united front dedicated to promoting the significance of licensed arborists and sustainable tree-care practices • Amplifying the association’s presence on both local and national stages to emerge as the go-to authority in arboriculture, and • Set new industry benchmarks.

• Through our collective efforts, the TCAAA will continue to grow, shaping an industry where qualified professionals are celebrated, valued, and entrusted with the responsibility of safeguarding our natural environment for generations to come.

Shakanda lighttruck chipper bodies

Specialising in custom-built, light- to medium-weight vehicle bodies, Victorianbased Shakanda has seen a shift in arborists’ choice of vehicle size in recent times.

W

ith a wide range of skills and design facilities, Shakanda creates a comprehensive range of truck bodies to suit client needs and vehicles of all sizes. Working with clients throughout the design process ensures longevity, functionality and an exceptional finish.

Key Features of a Shakanda chipper body include: • Bodies sandblasted, zinc primed and 2-pack top coated • Hot dip galvanised and Zinc plated components

52

THE AUSTRALIAN ARBOR AGE

• Bodies customised to individual requirements • An extensive range of optional extras • Quality and durability • After-sales service, and • Weight minimised without compromising structural integrity.

Light trucks

Managing Director Roger Bengtsson oversees the engineering and construction of a wide range of projects at Shakanda, but lately he’s seen an

increase in arborists, who would in the past have opted for a 4x4 light commercial vehicle, now requesting chipper bodies for larger vehicles within the 4x4 range.

“The demand for light-truck bodies is increasing,” he told The Australian Arbor Age magazine.

“Shakanda doesn’t build chipper bodies for light commercial vehicles because there’s too many issues associated with weight capacities and overloading. There’s a duty of care to be

considered by all.

“The larger vehicles are much more fit for purpose for the end user. There are plenty of good light trucks which are a little less expensive than some of the light commercials. The driver just has to move to a light-truck licence.”

Larger vehicles are much more fit for purpose for arbor and forestry work. There are plenty of good light trucks which are a little less expensive than some of the light commercials. Image: Shakanda

Expert knowledge

The stronger light-truck chassis doesn’t necessarily mean things are easier for Shakanda from an engineering perspective. Roger explained: “We design a particular body size for a particular truck, and the Gross Vehicle Mass (GVM) it offers, to ensure it is fit for purpose. Obviously, we custom design the bin for that truck to maximise the capacity of woodchips, even though the customer is moving into a bigger vehicle. That has its challenges when it comes to load and capability as well.

“We have two vehicles in our workshop at the moment: the Isuzu and the Hino. We’re still in development on the GVM upgrade for the Isuzu, but, for the 817, we can offer a GVM upgrade that gives the customer an extra 900kg over the Original Equipment Manufacturer (OEM) release.

The upgrade allows Shakanda to build a body which gives a better front/rear

axle balance, allowing the extra load to be carried legally and safely, and if that sounds like an engineering feat, it’s because it is.

“During the upgrade process we don’t exceed OEM manufacturing specification limits at any point,” underlined Roger.

“We don’t alter the Gross Vehicle Combination. We leave it the same. We only increase the GVM, which is still within axle limits as specified by the Original Equipment Manufacturer.

Win/win

The result is a more productive, less expensive and more capable work vehicle, ideally suited to arbor and forestry work, and engineered with a very high level of durability and safety.

Husqvarna’s Spire™ Vent Arborist helmet W

hen it comes to the arborist and tree-care industry, protection is critical.

Husqvarna’s Spire™ Vent Arborist helmet has been designed for the professional arborist who requires convenience and style at work without compromising safety and protection.

Fit and air flow

This advanced tree-care helmet is lightweight and well ventilated, with a universal fit and a wheel ratchet for easy size adjustment, and superior, streamlined vents allow heat to escape while boosting airflow. These vents help improve overall comfort when working in warm climates and challenging conditions, and also help minimise sweat and oil build up.

Quick-dry fabric padding lines the inside of the helmet, giving cushion-like comfort without the unpleasant feeling of saturated padding. Instead of absorbing moisture, the high-tech fabric dries very quickly, while improved airflow helps transport it back into the air and away from your head. The padding is easy to remove and clean, ensuring no odour and bacteria build up over time.

Comfort

The addition of an eco-leather, four-point chinstrap minimises chafing and skin irritation around the neck and jawline.

Eco-leather is naturally hypoallergenic, meaning the risk of experiencing allergic-skin reactions often experienced with chemically treated man-made fabrics is minimised.

When looking at safety, Husqvarna has taken into account more than just potential impacts.

Visibility is key to staying safe when working in bush, forests and farmland, which is why you’ll find strategically placed high-vis reflective stickers offering 360º visibility.

Summing up

To summarise, the Spire™ Vent Arborist helmet features: • High-vis reflective detailing for improved visibility and safety • Quick-dry fabric padding on the interior of the helmet 54

THE AUSTRALIAN ARBOR AGE

Husqvarna’s Spire™ Vent Arborist helmet has been designed for the professional arborist. Image: Husqvarna

• Eco-leather, hypoallergenic, fourpoint chinstrap for improved comfort • Streamlined and optimised vents and maximised interior air space • Easy-to-remove and easy-to-wash interior padding • Sleek and stylish overall design for a professional look and feel • Quick-release visor for fast and easy on-the-job visor changes, and • Removable harness front loop and helmet attachment loop.

Visors and accessories

A range of three visors has been created especially for the Spire™ Vent Arborist helmet (all sold separately): • Spire™ Vent Clear Visor – best for cloudy/low-light conditions • Spire™ Vent Smoke Visor – best for partial cloud/moderately sunny days, and • Spire™ Vent Silver Mirror Visor – best for full-sunlight/bright conditions.

No matter what the weather is doing or the task at hand, select the most appropriate visor, click it into position and get to work quickly and safely.

Finished with anti-fog and anti-scratch treatments, the in-built rubber seal prevents liquid from dripping into your eyes, while the panoramic design gives improved visuals.

Vehicle roll-aways Safe Work Australia has updated the model Code of Practice: Managing the risks of plant in the workplace to include guidance on vehicle roll-aways and safe immobilisation.

V

ehicle roll-aways – the unintentional movement of a vehicle that has not been properly immobilised – are a major cause of work-related fatalities and injuries in Australia. Roll-aways can occur with cars, forklifts, trucks, tractors and trailers, on worksites, car parks, maintenance yards or when a vehicle is parked on the side of the road.

When vehicles that have not been safely immobilised roll away, a person can be hit, crushed, trapped or run over – leading to death or serious injuries.

The Code now includes guidance on control measures to prevent roll-aways, including parking on a level surface where possible and using wheel chocks.

No commercial native logging in Western Australia

Under the new Forest Management Plan, native timbers will only be available by ecologically thinning.

The decision to stop the practice under the Forest Management Plan 2024-33 will protect nearly two million hectares of native karri, jarrah, and wandoo forests for future generations.

W

estern Australia is one of the first states in Australia to take the step of banning commercial native logging.

Following the move two years ago, the Western Australian State Government committed to an $80 million Native Forest Transition Plan that included significant industry restructure payments which have now been made to all eligible sawmills and businesses.

Millions of dollars have also been made available through various grants for community development projects, business diversification, and to attract new industries.

WA’s largest commercial timber mills have exited the industry, and the government is committed to working with the smaller sustainable mills that will play a valuable role into the future.

The plan

Under the new Forest Management Plan, native timbers will only be available by ecologically thinning, which promotes forest health and resilience from drought and bushfires.

The government is also investing a record $350 million dollars in WA’s softwood pine plantations, which will support thousands of jobs.

Pine from softwood timber plantations is extensively used in the construction of WA homes. Additionally, the plantations capture carbon dioxide from the atmosphere, helping to fight climate change.

Promoting conservation

“More than two decades after the Gallop Government ended old-growth logging, the Cook Government has delivered on

its commitment to end commercial logging in Western Australia’s native forests,” said Environment Minister Reece Whitby.

“This decision is a historic moment for WA. Our state is now one of the first in Australia to end native logging, a move which will promote conservation and resilience throughout our natural environment.”

“This historic decision reflects the changing climate and community attitudes, and will safeguard our iconic forests for years to come,” said Forestry Minister Jackie Jarvis.

“This is a new era for our WA’s southwest and I am proud to be part of a government that is prioritising forest health and supporting the local industry to diversify and grow.”

Native forest logging to continue in NSW

The Federal Court has dismissed a challenge to native forest logging in northern NSW.

J

ust as we were off to print news broke that a challenge to native forest logging in northern NSW had not succeeded.

The challenge was raised by the North East Forest Alliance, who fought against timber harvesting across four million hectares of native forest stretching from Sydney to the Queensland border – a considerable expanse of coastline and home to several endangered species.

The essence of the challenge related

to a regional forestry agreement between the Commonwealth and NSW governments which, the Alliance claimed, shouldn’t have been renewed without being subject to assessment and approval requirements set out under federal environment laws.

The case was dismissed on Wednesday, January 10, by Federal Court Justice Melissa Perry, who said, “A regional forest agreement provides an alternative mechanism by which the

objects of the (federal) Environment Protection and Biodiversity Conservation Act can be achieved by way of an intergovernmental agreement,” The Australian Forest Products Association had warned thousands of jobs could be on the line if there was a shutdown of logging across a large area that provides much needed hardwood for construction and other purposes, and will no doubt feel relieved at the decision.

Quinton Garlick is big bloke, there’s no doubt about that, and it’s fitting that one of the biggest prizes in Australian arboriculture went his way when he picked up his Husqvarna 525PT5s Pole Saw from Jason at The Red Shed in Cranbourne, Victoria.

We were busting to know how the saw shaped up as part of Quinton’s arsenal at Cut It Right Tree Service.

“To tell you truth, I haven’t used it yet,” chortled The Big Fella.

When he won a chainsaw at the Victorian Tree Climbing Championship some years ago, Quinton was so rapt he wanted to gold-dip the bar and just keep it in pride of place.

“But I never did it, did I?” he laughed. “The Husqvarna will probably sit there on the trophy shelf for a little while, but then I’ll grab it and get to work.”

What a dead-set champion, and a deserving winner.

l

don’t recall getting significant feedback during my 23-year career as an arboricultural writer. I’ve had the odd nod and thank-you, but largely straight silence – until some particularly constructive feedback on my August/ September 2023 piece Plant Health Care – the ®evolution.

Thanks to this recent feedback I’m expanding on the tree-health-care topic. With plant health care (PHC) we are ensuring our city trees enjoy a greater surface area for nutrientabsorbing roots, nutrient absorption, and the rhizosphere, involving multiple oxygenated/hydrated pathways into compacted/deficient soils.

The best professional advice I ever had from anyone in vegetation management

62

THE AUSTRALIAN ARBOR AGE

came from a botanist who directed me to ‘study the nutrient-cycle’.

In the beginning

My history in what I call ‘holistic arboriculture’ goes back to Merrist-Wood (1990-92), talk of mycorrhizae, then Shigo and that classic ’97 AAA article Troubles in the Rhizosphere. In 1998 I did a Totally Wild television episode on ‘tree doctoring’ a schoolground Brisbane fig tree. It simply involved adding air, water, carbon, and associate plants.

Active experimentation, founded on a horticultural background, led to my early creativity in the field. l started cultivating what I named ‘nutrient beds’ (which, when activated with fungi, also became a nutrient

sponge) and ‘plant systems’ (the plant component of an ecosystem), utilising the bare bones of nature – ripped rawtimber as edging, composted mulches, harvesting inoculum from Bush Turkey mounds, and introducing the native rainforest fungi Phallus rubicundus.

As Phallus rubicundus turns mulch to humus it supplies carbon to the microorganisms that help release the macroand micro-nutrients.

On top of that I was making vertical fissures in soils to help with aeration, water distribution and mycelial propagation.

Answering a need

Due to the lack of explanation in support of conservation and plant health care,

Fig 3 (below): Brown-rot decayed wood sample, with cellulose digested this material is brittle like coal, natures-biochar, habitat for microbes whilst holding airgaps in the soil, though also stocked with a far greater food-source than we can concoct. Images: Cassian Humphreys

I co-created the terms ‘oasification’ and ‘desertification’. Where on-point words are missing, new words can help us understand concepts and ideas. The concept of ‘oasifying’ the land in support of trees is the whole point of tree health care and the PHC movement.

Holistic health

Like holistic health care of humans, holistic health care of trees is based on natural precedent. All biological life is driven by the nutrient cycle, or in the case of land plants (as the pump), the interfaces between the atmosphere and

the rhizosphere.

In the case of animals and humans – that interface is our stomach-lining.

Sunlight, air, water, and biologically active carbon are essentials for trees.

Associated plant microbiology looks after the details, including the timing THE AUSTRALIAN ARBOR AGE

and supply of nutrients. This is validated by study of soil-food-web science and the leading educational microbiologists.

Application of the essentials (carbon with probiotics) in soils is the heart of plant health care. To be holistic we just need to mirror nature’s detail.

This is impossible if we only reference the man-made big-pharma model.

Fertilisers, herbicides, fungicides and so forth make up a suite of products that are about longevity of industry over longevity of biology. This study reflects a conservation arb approach to achieve plant health care.

Technical feature Sunlight is a given, adding air, water, and bio-carbon in soils requires greater detail to get right. Detail and holistic arboriculture go hand in hand. When we mimic nature’s processes the detail is taken care of by Mother Nature.

However, detail is also about application. When it comes to the nutrient cycle, as with arb operational safety, we need to be concerned about human shortcuts – such as using static piles of green, chipped vegetation. To best support nature’s cycle we must mirror the nutrient cycle, which, via natural succession, processes vegetation minus the photosynthates, or sugars.

In nature the parts (leaves, twigs, and limbs) and processes draw the sugars out prior to shedding, to then be broken down via the microbiology.

The same applies to us. Hence the benefit in eating probiotic-rich foods such as sauerkraut and kimchi. Eating excess sugar kills our gut-health.

Artificial is not natural

What trees need for longevity is inherent to the natural cycle.

This isn’t supported by manmade, containerised products.

As soon as biology is packaged or compartmentalised from nature for any length of time it dies or goes dormant. Compost tea is a classic example. If microbiology in solution isn’t kept aerated it changes from being compost-tea to being a stagnant bacterial soup. A simple rule of thumb is if it either stinks or smells inert, it’s not much use to woody plants that need soils or solutions (think of aerated springwater) lower in bacteria.

With harvested green mulch this must be cold-processed, or temperature controlled, via regular turning and irrigation.

Friability

When considerating air in soils, one word is key – friability.

All arboriculturists need to understand the meaning of this word intimately, and to be able to recognise healthy, friable soil by the senses.

We should never plant trees in ‘dirt’ (structureless, biologically inert soil) without at least treating it at the planting stage. For best practice it’s better to treat damaged soils beforehand. Leaving desertified soils to go fallow and grow weeds is a first simple step in holistic arboriculture and in conservation.

The right balance

To know what makes a healthy soil or compost, the best place to learn is in nature’s ecosystems, where shed vegetation builds up.

l covered my sources in the first part of my 2022 article on land care. Australia was known to the First Nations people and the European biologists as being a land of friable soils. Until we learn how to restore soil friability by adding air, water, and biology, I maintain we’re unable to practice arboriculture. This also applies to water retention and enabling natural propagation of beneficial fungi in soils (like Trichoderma). We need sufficient soil/ oxygen and soil/water. The balance of air/ water/carbon supports the activation of the microbiology responsible for nutrient assimilation and disease suppression.

Understanding this is why Shigo documented the tree as a living pump, the symbolic logo for modern arboriculture.

Conservation arb, holistic arb or plant health care, along with crown volume reductions for crown subordination, is proactive arboriculture at its best.

Rooting for better practice

Alex Kalivadova, BSc, Dip Arboriculture, outlines the consequences of root-deformity and why arboriculturalists should take steps to avoid or remedy the problem.

H

ave you observed plants suddenly dying or plants never seeming to establish? Maybe you’ve seen epicormic shoots at the base, pest issues or trees tilting – needing external structural support. These are just a few of the reasons why we must start paying more attention to the quality of plant stock used at planting time.

During my combined time spent in forest regeneration, home gardening and observing professional commercial/ residential gardens, I’ve observed several inefficiencies that hinder successful outcomes. Namely, the use of nursery stock with significant root deformities.

Below are the most common problems stemming from this practice.

Structural instability

The shortage of well-developed lateral roots directly translates to a lack of sufficient tethers to the tree trunk, rendering it vulnerable to strong winds and soil slippages. Even in professional gardens I’ve occasionally seen a semi mature tree with a strong lean tied to a star picket to prevent it from completely falling over.

Where we could have had a multigenerational asset, we now have a liability.

Stunted growth

Root deformities prevent plants from accessing nutrients from their surroundings.

Returning to a site three years after planting, I found a Kunzea ambigua barely taller than the grass around it. A three-year-old tree could be so much taller than this. Upon inspection, the root system had barely expanded and was still in the shape of the pot itself. Instead of a one-metre tall tree, we have one marginally larger than a tubestock with no ability to get much taller.

Plants not reaching their full potential has obvious implications in our warming climate.

Poor resilience to extreme weather Major root deformities are permanent and prohibitive to subsequent root 70

A well-developed root ball.

Images: Trees Impact division. Unless remediated with root pruning, the plant has no opportunity to correct and expand its root system.

This means when we plant it in its final location it is as though we have left it in the pot in that same location, subject to much harsher conditions when compared with the sheltered nursery environment.

I’ve seen numerous plants completely sign out after just a couple of 35-degree days, despite being regularly watered.

What are the broader consequences of this being the norm?

The implications of this issue are far reaching and present losses for everybody from the landscape contractor in the form of replacement costs, to the general public and the environment with amenity degradation.

When done wrong, it presents a major hazard to people and property as well as being a huge lost opportunity to host a majestic living structure providing a myriad of benefits.

If our rate of replenishment cannot meet the rate of removal we exacerbate the effects of the warming climate and make our cities more unliveable.

Who is this a problem for?

One could think nurseries are the sole beneficiaries in this bungled supply chain; parting with the product to make a buck and cutting all contact with the project. Grow, sell, sleep, repeat.

However, one would be wrong.

There are losses in store to every party for whom these plants make a part of the business.

An example of this is stock shrinkage due to premature death. Plants with root deformities are negatively impacted by harsher weather, develop a worse appearance, and need to be sold for less or die completely, enhancing the sale section of Bunnings. To clarify, the sale section excites me as much as the next person alive, but this contracts

above-mentioned categories, rest assured this issue is pervasive and affects everybody who wants to live around plants in the future.

In a nutshell

This problem has emerged from deficiencies at two stages. One is the rushed production of stock at nurseries, and the other is the broad acceptance of this stock by landscape planners. So, what does it take to grow plants that comply with the Australian standard?

In the nursery, we must renounce the idea that the most important factor in production is quantity. We need quality over quantity. Self-germinated trees have root systems adapted to the soil environment they originated in – extending and branching in response to the wind loading on the tree, and in directions where nutrients and moisture are most abundant. A planted tree is not assigned the same luxury; it must make the best of limited soil volumes where the conditions are often hostile at best – compaction and inverted soil profiles just to name a couple, commonly

On these pages: Implications of the issue - suckering at base, vulnerability to pathogens, unstable in ground. Images: Alex Kalivadova the profits for the nursery and renders any resource used to establish plants to that stage wasted. A complete lose/lose situation.

Next down the chain are councils and land holders, for whom stunted, unsuccessful plants needing replacement prematurely are antithetical to progress. As the maintenance budget for new plantings is often miniscule, the project depends on the plant’s stored resources, commonly disguised as roots. The assumption behind buying a larger plant is that it likely has more stored resource to bridge that gap between maintenance waterings. For that assumption to be true, we depend on root occupancy.

With deformities persisting, roots are unable to branch evenly to colonise the entire volume of soil. So instead of buying an advanced plant, you actually buy a small plant in a larger volume of unoccupied soil – an unfortunate prank.

If you don’t fall into either of the THE AUSTRALIAN ARBOR AGE

71

Technical feature

Real examples of the issue encountered in the field. Images: Alex Kalivadova found in most urban planting spaces.

When the issue of limited root systems is combined with the already compromised planting position we can clearly see why a tree might fail to thrive. Each root tip represents an opportunity to acquire stability and nutrition; the more lateral root endings present, the greater the chance of establishment despite inhospitable conditions.

In the nursery

To continue, we need a little extra care when transferring plants into larger pots. Having observed root 72

THE AUSTRALIAN ARBOR AGE

deformities in very young plants (tubestock), it becomes evident the root defects get instilled in the stock very early on in the growing process and they get carried through to subsequent growth stages. Single rooted seedlings are often condemned early by having their delicate root distorted during the potting-on process. If this single step could be slowed down and done with extra care, it would disproportionately improve the quality of the resulting stock. Alternatively, seeds can be germinated in larger volumes of soil so the root system can establish a little before the pot size is upgraded. These

efforts could then be rewarded in the form of a higher price point for better quality stock.

In summary, both management and staff of nurseries need to be on board for project quality. A development program adjusting nursery operations to optimise stock quality is needed. A long-term passion of mine.

Watch this space.

In the field

The other half of this problem is the broad acceptance of compromised stock at planting time, which is almost understandable as the issues lie

Australian standard AS 2303-2018 Tree stock for landscape use, outlines the traits that are most advantageous for plants to thrive, including detailed procedures for testing stock before purchase to ensure the success of the planting.

Due to our proximity to this issue, we as arborists can directly influence its trajectory. Arborists in charge of planning planting projects are prompted to recall the feeling that seeing a wellplaced, stately tree incites. Planting is a huge opportunity to contribute to people

and the planet, and project managers would be wise to accommodate whatever delay is caused by the search for quality stock in pursuit of excellence.

Why really do any of this?

The implication of our work reaches much further than just the completion of a contract. It would make sense for us as environmentalists with altruistic intents to ensure we are truly doing what we have set out to do. There are obvious benefits to be realised when nothing other than quality will do. Time, money and effort are all conserved. Not only is it valuable as environmental and social

contributions, but also as good business people.

Let’s not measure success by how fast we can pack up the shovels. Let’s instead measure success by the number of thriving trees we can enjoy 10 years from planting.
