SHEFFIELD COUNCIL RAPPED OVER CALLOUS TREE FELLING he eld ity ouncil fell far short of good practice” according to the orestry ommission, which has released its report into the city’s Streets Ahead programme that resulted in almost 5,500 trees in the city being felled. However, in the report, the regulator of the Forestry ommission said there was insu cient evidence to say if the council had acted illegally by failing to obtain a licence for the felling. The council had claimed that all the felling under Streets Ahead was in response to its statutory
news duty under the Highways Act and was conducted to maintain roads and make reasonable adjustments for disabled people. The orestry ommission had accepted this until the terms of the contract between the council and infrastructure support service provider, Amey, was made public in 2018. This is when it was questioned whether the felling was lawful without a felling licence. Even though there will be no prosecution, the council was criticised for poor record keeping, engagement and consultation,
tree management techniques and contract management. The report stated he eld ity ouncil and other local authorities must take note for future operations.” Former environment secretary, Michael Gove, has described the council’s actions as “a schedule of careless felling characterised by a lack of community consultation and a casual disregard for the urban environment.” He also stated: “The campaign of felling seemed beyond logic, and the council’s ustiﬁcation was as ﬂimsy as an autumn leaf.
What happened? In July 2012, the council entered into a 25-year PFI contract with Amey to deliver Streets Ahead, containing a commitment to fell 200 trees per annum. 5,474 trees were felled by 2018. The orestry ommission received allegations from local activists that Streets Ahead may constitute illegal felling back in 2016, but did not act because the contract details were unavailable. www.gov.uk/government/ organisations/forestrycommission

TIMBERWOLF ‘INSPIRES’ IN LSE REPORT Wood chipper manufacturer Timberwolf has been included within the ‘1000 Companies to Inspire Britain’ survey, as part of the London Stock Exchange Group’s 2019 report. The listing focuses on the UK’s fastest growing and most dynamic SMEs over the last three years, with companies representing over 40 sectors and spanning all parts of the country. Stowmarket-based Timberwolf was selected among a group of ﬁve businesses nationwide to represent the engineering and manufacturing sector. It was highlighted as a leader within the manufacturing sector.
Timberwolf produces its 750kg wood chipper series – the TW 23 PA and T 23 – from its manufacturing facility in uﬀolk. These two machines have contributed signiﬁcantly to Timberwolf’s growth in the UK and Europe, with sales increasing by 256% since 2013. Chris Perry, managing director at Timberwolf, says: “Everyone works incredibly hard to deliver unbeatable power and performance from every machine, so it is a real boost for the whole team. We have grown considerably over the past few years, so are very proud with recognition on the national stage.” www.timberwolf-uk.com
CORNWALL COUNCIL ISSUES WARNING OVER BOGUS TREE SURGEONS A tree o cer from ornwall Council is urging residents to be on their guard against imposters claiming to be tree surgeons. Alan Rowe, of the Arboricultural Association, said uninsured and un ualiﬁed arborists can cause in ury and damage . e added residents should be prepared to check paperwork to ensure the tree surgeon is insured, holds the required professional certiﬁcates and works to the correct standards. e added arborists should always provide a written quotation and possibly a contact
for a referee, as well as proof they are a member of a professional organisation. Any trader who solicits work door-to-door or who does not provide a permanent address should be avoided. Rowe continued that an oﬀer of a topping service in which the whole tops of trees or large branches or trunks are removed, should be avoided as the technique is harmful to trees. During any work, the arborist should be seen to be using safety equipment at all times. e said e see some shocking work carried out by
traders who do not understand what is best for the trees and are conning the public into believing they are professionals. Tree work operations or arboriculture require a high degree of technical competence, supported by training and experience. “For these reasons, tree work should only be undertaken by well-trained, competent arborists who hold adequate insurance. Picking the wrong arborist could lead to damage to people, property or trees that have taken years to grow.” www.trees.org.uk
‘TREE CHAMPION’ WILLIAM WORSLEY TO ADDRESS AA AUDIENCE The Arboricultural Association has released information on the speakers for its 53rd Amenity Conference. The event, Crown and Canopy Management – Working with Nature, will be held from 8 to 11 September at the University of Exeter. ir illiam orsley, the ﬁrst ‘tree champion’ appointed by Defra in June 2018, will provide the keynote speech to open the ﬁnal day of the conference. e will speak on his evolving role, and how arboricultural professionals
are crucial to the success of the government’s tree health strategy. Worsley is a forester, farmer, businessman and a former president of the Country Land and Business Association. In 2016, he was appointed chair of the National Forest Company, which oversees the National Forest – the largest environmentally-led regeneration project in England, covering 200m2 of the Midlands. Other speakers include climber on artill, who will seek to challenge perceptions
of the impacts of crown reduction. Consultant Paul Muir will also speak on crown reductions, and has undertaken static load tests to assess the structural condition of over 200 trees throughout the UK and Europe. Details can be found at www.trees.org.uk/amenityconference and there is also a report on page 17.

Stay alert to power line dangers news
ARBORISTS CAN BE PARTICULARLY AT RISK OF ELECTROCUTION WHEN WORKING OUTSIDE AT HEIGHT – AWARENESS OF HOW TO MANAGE THEIR SURROUNDINGS COULD PROVE LIFE SAVING
A recent inquest has delivered a verdict of accidental death when investigating the case of 27-yearold Marcus Pepper. He had been trimming tall hedges from a MEWP at the Hall Grove Industrial Estate in Bagshot during poor weather conditions when he came in too close to overhead 11,000volt powerlines and suﬀered a fatal electric shock. It remains unclear whether he was aware of the dangers – the owner of the property, Brian Wooldridge, said he had told Mr Pepper to steer clear of the powerlines. Mr Pepper had agreed to cut the hedges in return for being allowed to store some of his kit on the property. However, this was disputed by assistant tree surgeon Luke Nabil, who was working with Mr Pepper, as he said they were unaware
Pro Arb | Summer 2019
of this instruction. Mr Nabil also received injuries when he tried to assist Mr Pepper, but recovered after hospital treatment. Whatever happened, it does seem that Mr Pepper, who had studied at college and was experienced in tree surgery work, was keen to do a thorough job. His father described him as someone that “wanted to please”. The inquest heard from Amanda uﬀ, an inspector, who visited the site and carried out an investigation. he explained that as Mr Pepper was self-employed, he would have
been responsible for his own and Mr Nabil’s safety and that the MEWP had in fact been positioned too close to the power lines. Furthermore, there should have been an exclusion zone. When arboricultural works are proposed within 10m of overhead power lines, the emphasises that a risk based approach needs to be adopted. Before undertaking any work that falls in range of this distance, you should seek specialist advice and guidance from the owner of the power line (network operator). From here, they should assist in establishing a
safe system of work. This could include arranging for the electricity to be switched oﬀ or reﬁning safety distances. t could also include arranging for specialised utility arboricultural contractor to carry out works. ltimately, the says the ﬁrst choice when managing risks should be to undertake the works dead. tuart Parry, from ’s Forestry and Arboriculture Team, comments: “There are unfortunately still too many safety-related incidents within the industry – power lines are

A site visit will be conducted to ensure cutting oﬀ the power is the
correct course of action – both the property owner and the arborist needs to be well informed about the process and plan the work carefully around when the shut down will occur. Typically, the maximum length of time power will be switched oﬀ for is eight hours. or more information and to make an appointment with the relevant network provider, you can refer to the A’s electricity distribution map www. energynetworks.org/info/faqs/ electricity-distribution-map Choosing to specialise? ecause of the nature of the work, utility arboriculture can oﬀer a range of specialist careers. ome arborists may choose this route if they have gained more general experience elsewhere. efore entering this sector, training must be taken, and this can range from basic to advanced and should cover the e uipment

et in the idyllic Kent countryside, with a beamed barn as the combined classroom and workshop, the setting of Kingswood Training is the place to come for some supreme learning in a picturesque setting. Kingswood aims to help its students become highly competent in a relatively short period of time, and this is why its combination arborist training course is so popular. Many who want to become arborists do not have the time or

ﬁnances to cover the two years of education, typically required for full-time college courses. Instead, they want to take a short, intensive courses that provide the knowledge and skills necessary to work soon after ﬁnishing as an arborist. With Kingswood, this could happen in around six weeks or less – which makes it an attractive and a particularly practical option. Kingswood is often ﬁrst port of call for those who are seeking a career change. The business is known as a centre of excellence – it oﬀers top-quality training, whilst being a more aﬀordable route into the sector with its highly intensive courses. Kingswood’s reputation is such that students come from all around the UK, and the world, like Australia, the US, Canada and Europe. The business was founded in June 1987 by arborist Richard Olley, just a few months before
the notorious hurricane, the Great Storm, resulted in 15 million trees being uprooted. The value of arborists was on show that summer, as they were called on to help clear up the devastation, but as the years progressed, the business grew in reputation for the expertise it imparted. From here, it began attracting students with varying needs, ranging from complete beginners to experienced practitioners needing a refresher course. Kingswood Training is now run by three directors – Michele Holmes, Tony Lucas and Jim Chatton – who work as a co-operative. They had all previously worked for Richard and took over the business when he retired last year. Running the show is something all three are ﬁnding hugely rewarding and they are already growing the business. They were involved in developing the new classroom and securing additional woodland for outdoor training, enhancing the website and attracting more students. anaging courses, the ﬂow of students, marketing and the website is Michele’s domain, along with arranging accommodation for those who need it.

body Lantra,” says Michele. “Our instructors have years of experience and there are also independent assessments by independent NPTC (City & Guilds) to give assurance the required standard has been reached.” Once the course has ended, the NPTC assessment is booked. Candidates need to show they are fully prepared and competent. They need proﬁciency in nglish, and they will take the assessment on a familiar site where the course took place and using equipment they have been trained on. Kingswood does not inﬂuence the assessment, which despite being rigorous, achieves extremely high success rates, even if some – typically less than 5% – do not make the grade. “It’s obviously a shame if someone does not pass, but we won’t send anyone out to work in such a potentially dangerous sector if we are not 1 conﬁdent they can work safely. This is why an independent assessment is so important,” explains Michele. Previously, Kingswood was known for their work with a number of ex-army students. However, while these still exist, the numbers have reduced in recent years. “They no longer receive government funding, and if they need support to pay fees, this tends to come from charities such as the Royal British Legion. But, we really enjoy teaching former soldiers as they tend to have a great attitude and are very quick to learn.” Michele adds there is now a more diverse group of students and they are often people who want a career change. “The vast majority of those who come to Kingswood are very serious about wanting to become arborists

Tony and Jim lead the majority of the arborist training, although other vetted professionals are brought in when necessary, such as for ﬁrst aid. im explains that ﬁrst aid is viewed as essential and can literally mean saving a life. “You can be working in some remote area and be involved in a chainsaw accident, or even fall, then treatment must be given promptly – ﬁrst aid knowledge is crucial for all arborists and uick action can make a huge diﬀerence. He adds: “We want our students to be professional when they start work. That means
The students in action on the course getting the basics right, such as wearing full PP and always thinking about exactly what they are doing and where. Often, a problem like kickback when using a chainsaw can occur because the user is not fully aware of how to avoid it. They could also be failing to carry out proper maintenance which can increase risk.”
the necessary standards, there’s plenty of opportunity, whether ﬁnding work for a reputable ﬁrm, setting up as an independent or working for a local authority. There’s growing awareness of the importance of trees and maintenance. t’s a complete misconception to see arborists wanting to simply fell trees – this
first aid is viewed as essential and can literally mean saving a life. “You can be working in some remote areas or in the event of a chainsaw accident or fall, then treatment must be given promptly”

He adds that one of the most rewarding parts of the work is seeing students develop. “It is so satisfying when attending an event like the Arb how, for example, to have people ’ve trained come up to me. Many will have been complete beginners, but they have gained their suite of tickets with us, and let me know how they’re doing. t’s fantastic to see so many thriving and working as professional arborists.” Both Tony and Jim agree that professionalism is increasingly important, along with the idea that, for those who can achieve
is often only a case when it’s a ha ard and there’s no alternative. The examples of positive feedback from former students is a testament to Kingswood’s success. Praise has been given for friendly and patient tuition that’s highly professional, and references to the life changing experience of ﬁnding a new career started as a result of passing a course. Can you change your life after four weeks? or those wanting to be ualiﬁed to work with trees, Kingswood looks like the way to do it.

NEWS & VIEWS
at the heart of
LEARNING AND NETWORKING ARE SET TO BE IN ABUNDANCE AT THIS YEAR’S NATIONAL AMENITY CONFERENCE
he Arboricultural Association (AA) 2019 conference is ‘Crown and Canopy Management – Working with Nature’ and will be held at the University of Exeter on 8-11 September. The event is the UK’s biggest arboriculture conference, and includes 13 international speakers, who alongside UK based experts, will focus on the science of crown management. It will cover managing trees and tree populations, from the macro to the micro, through to canopy and crown. According to the AA, this is a topic that has an impact on all professionals involved in the tree care industry – from those dealing with policy at local, regional, national and global levels, to those who are working on individual trees, like climbing arborists, consultants, speciﬁers and practitioners. The four broad topics are as follows: • Natural function • Governance, guidance and application • Pruning methodologies • Challenging current practice.
Arb Association KR.indd 17
The association has gathered a range of experts to present the latest research innovations and practices – challenging the ways we manage the tree crown and canopy. One highlight will be the Sunday conference, beginning with a visit to Dartington Hall Estate, Totnes (home to tree collections and innovative projects). Another, will be Dr Cecil Konijnendijk, project leader of the UFORIA (Urban Forestry Research in Action) lab at The University of British Columbia. Cecil will present a critical look at the use of canopy cover targets by governments. He said, “Canopy targets are clear and measurable, and often popular with politicians. However, on the negative side, urban forest canopy information is less useful for some urban forest beneﬁts – it can lead to over-focusing on aspects of quantity, where the functionality and resilience quality of the urban forest is just as important.” Ancient and veteran trees specialist, Vikki Bengtsson from Sweden, will challenge current practices of ‘veteranisation’ (creation of dead wood habitat on trees). Vikki explains: “Most inspiration for the techniques has come from observing natural processes.” Her presentation will include: why veteranisation is worth considering, experiences from the last 20 years, diﬀerent techni ues, and challenges. Some results from an international trial (Sweden, Norway and England) will also be presented, which was set up in 2012 – with 20 sites and 980 oak trees.”
An enlightened approach “The aim is to explore the latest understanding, theories and technologies, while looking at past and present practices, to help drive the industry towards a more enlightened approach to the urban forest,” says AA. The event, cosponsored by Bartlett Tree Experts, will provide four practical workshops on the ﬁnal day. 2018 saw a record of 426 attendees. This year is the 53rd AA conference – the ﬁrst having been held at Merrist Wood College in 1967. For more information, visit: www.trees.org.uk/Amenity-Conference

How tolerant are trees
to poor pruning? IN THE LATEST CHAPTER OF HIS CASEBOOK, DR DUNCAN SLATER ARGUES AGAINST POOR TECHNIQUE BUT SAYS TREES WHICH HAVE BEEN DAMAGED MAY BE CAPABLE OF RECOVERY If you’re a well-trained arborist, then not only should you know how to prune a tree correctly in theory, but you can also do it in practice, again and again, with few (if any) errors. But, let me tell you – if this is the case, then you’re quite the rarity. I hold a large collection of tree-related images and plenty of photos of pruning cuts and pruned trees. Sadly, the majority are of poorly enacted pruning, revealing stub cuts, ﬂush cuts and horrendous internodal large diameter branch reductions to tree species that are not suited to such heavy reductions. Throughout this article are a few particularly ‘interesting’ tree pruning images that I hope are worth sharing. ca ore sacri ce The ﬁrst set of images show a large limb removal on a mature sycamore (Acer pseudoplatanus L.), carried out ineptly. There was some breakage as the limb was cut oﬀ due to the uneven surface of the pruning wound. This is an extremely large wound on a mature tree; it was never going to close up in the 12 years since I last visited the tree. The tree is attempting closure – you can see some woundwood
DUNCAN SLATER.indd 21
VIEWS DUNCAN SLATER
Large ‘amateur’ cut to sycamore forming slowly around the cut. The closure of pruning wounds is related to the growth rate of the tree that has been pruned. Wound closure is in fact not a wholly separate process from the growing of new layers of wood over the whole structure of the tree – it is highly-related to the rate of secondary thickening that the tree is currently achieving. Prune with poetry There’s a rhyme I’ve been working on to guide students (with a few caveats) on pruning young and mature trees: “Small cuts to a young tree will close pretty quick, Large cuts to a young tree might just make it sick,
Twelve years later Small cuts to an old tree will close in the years to come, Large cuts to an old tree – what the heck have you just done?” Topping vs. pollarding Several books and articles try to deﬁne the diﬀerence between ‘topping’ a tree and ‘pollarding’ a tree, but there can be no strong separation. Both involve removing the majority of the crown of a tree to leave a basic branch framework on the remaining tree trunk. The clearest diﬀerence between the two is that topping is arguably enacted late in the tree’s development and is a one-oﬀ action, whereas good pollarding is carried out early in the tree’s development and repeatedly.
If you’re pollarding a tree, how often should it be done? Modern Arboriculture by Alex Shigo includes the statement: “Once the framework is established [on a pollarded tree], all sprouts are cut back to the framework every year.” However, that is highly unrealistic – most cannot cope with having all their sprouts removed every year. Traditionally in the UK, ash pollards were run on a seven to 15-year cycle, based on the dimensions of the branches that the landowner wanted to obtain through the pollarding process. Hornbeam pollards (common in woodlands around London and managed for ﬁrewood production) were typically cut every 11 to 15 years. Most large-grown trees would die if you cut oﬀ all their sprouts every year. There needs to be time for the ‘re-growths’ to supply a su cient amount of carbohydrates to the tree for it to be sustained. Resilient limes Of species that can take severe pruning and repetitive short-cycle
Pro Arb | Summer 2019 21
“Pollarded” lime tree pollarding, one must admire the tenacity of limes (Tilia spp.). The second image set shows a maturing small-leaved lime (Tilia cordata) that was initially ‘topped’. There were some large diameter cuts to start with, recut the following year and then allowed to regrow a full crown – as can be seen 12 years later. This is certainly not professional tree work, but it does show the great tenacity of this species and how it will attempt to regrow its crown despite severe reduction. It’s important to see ‘topping’ and ‘pollarding’ as a continuum rather than setting a closed deﬁnition that separates them entirely. Poor pollarding to a tree unsuited to that treatment can be as bad, if not worse, than topping a young tree. The lime will come back from such ruthless butchery repeatedly, and for most trees, do not follow the guidance in ‘Modern Arboriculture’ concerning annual re-cutting. There needs to be su cient regrowth. he conse uences o ushing The third set of images show a four-year time-lapse of a ﬂush cut to a young oak tree (Quercus robur L.) in a churchyard near to me by an amateur. If you look at the shape of the re-growth, you can see that the top and bottom

Twelve years later... of the wound are slower to close than the sides, because the tree’s trunk tissues have been damaged by this overly-close ﬂush cut. Even if you do a good cut based upon natural target pruning (NTP), you mustn’t expect to see a doughnut-ring of callous around every cut you’ve made the next year. A saw cut breaks the ‘sealed unit’ of a tree, lets in air and microbes to the inner back – causing that to partially die back and dry out because of the cut. It is like the cambium takes a step back before it can come forward again to occlude the wound. What would have happened if a cut based on NTP had been carried out to this tree? Firstly, the trunk would not have been
damaged directly – so that’s surely a good thing. Why damage the trunk when removing a branch? Additionally, the wound would have been smaller in diameter and would have closed quicker. t looks to me that this ﬂush cut is going to take six to seven years to close: a correct NTP cut would have closed in three to four years. For this particular cut, where the branch was only about 750mm (3 inches) in diameter, this ﬂush cut is not going to have big consequences for this young oak. Scale that up to a larger cut on a tree that is growing more slowly, and that diﬀerence in closure rate becomes much more important. The scientiﬁc research that backs up NTP principles is robust. If your intention is to minimise pruning wound size and the risk of infection or decay, nothing yet beats the NTP recommendations, which our current British Standard for tree pruning (BS 3998:2010) is currently based upon. hink o the conse uences When a tree is topped or heavily crown-reduced, this has lifechanging consequences for the tree. It will never return to a fully natural shape – cuts may
induce early-onset decay in the tree and, at times, re-growths may not be well-attached and can fail in strong wind. However, recovery is possible, particularly if the tree was relatively young when severe cutting was done and the re-growths managed to prevent natural bracing occurring, encouraging a suitable crown shape to develop. The species matters. Rapidly re-growing sprouts on a topped mature poplar tree will be liable to break oﬀ as decay sets in to the large diameter cuts. Slower growing shoots of a topped yew tree will cause little problem in nearly all scenarios. With urban tree populations under threat, ﬁnd the willingness of some arborists to dismiss the potential value of a topped tree disturbing – many do recover to be trees of considerable aesthetic and ecological value. f an unlucky person sets oﬀ an IED, causing life-changing injuries, their life will never be the same again. However, their wounds heal and over time they make a meaningful amount of recovery. In that state, does the doctor then decide to condemn them as a ‘low-value’ person? Fortunately,

August 2007 not. For trees that grow back well after such brutal pruning, I would treat them the same as that recovering human patient. Cherry on the mend Pictured above in the fourth image set is a wild cherry (Prunus avium L.), which was poorly pruned. Many with the ‘purist doctrine’ that topped trees are bad trees would have written it oﬀ. But look at its recovery 11 years later. Although its branch structure is irrevocably changed, it is a ﬁt-for-purpose amenity tree. Some topped trees come to live a long time – including many veteran trees that are ‘ex-pollards’ or ‘ex-topped’. A good arborist should have the vision to see what a young damaged tree could turn into and not condemn every topped tree as a ‘write-oﬀ’. A good, young tree in a garden being topped is always a shame. Some can’t see the potential for such a tree to recover and be of use – that is also a shame. Both problems need addressing.

April 2018 Learn the techniques I used to train mature students looking to obtain their Royal orestry ociety (R ) ertiﬁcate, including tree pruning techniques. I tended to concentrate on NTP techniques as the course expected students to be able to prune forestry trees. NTP is ideal for that, as it minimises damage to
the trees and helps generate knotfree timber as the trees grow. have used a apanese pullsaw for pruning minor branches since 1993. I knew it would be more eﬀective than other handsaws or bowsaws. They are sharp and good at achieving smooth, straight cuts, based on the principle of cutting the
branch when pulling – rather than cutting when pushing. The ﬁfth and ﬁnal image set highlights a wild cherry tree I pruned with my pull-saw as a demo for my RFS students, where cuts had occluded well. If you were to cut down this tree and split those old branch junctions open, you would only ﬁnd some minor discoloration in the wood: no signiﬁcant areas of decay no signiﬁcant problems that would aﬀect the tree in later life. The information about how to get it right is out there, supported by science as well as many well- ualiﬁed trainers. et poor tree pruning persists and is the ‘norm’ in many private gardens. Perhaps this is one reason that the arboriculture industry should be more regulated. Fixing boilers requires being on the Gas Safe Register, so perhaps arborists should have a tree pruning licence before they can start work?

Be sure to dispose of the pruned material immediately (such as through burning or chipping) as fruiting bodies will still form if left lying on the ground. Following removal, protecting pruning wounds using fungicide paints is recommended.
Because pruning can allow the fungus to enter a branch, try to prune between June and August. This is when fruit trees produce gum in their tissues, making them more resistant to the spread of silver leaf fungal threads. Caution should be exercised outside these months, particularly if other trees are showing evidence of silver leaf. Be aware as well that plant vigour is an important factor in increasing resistance to attack and/or reduce the severity of symptoms. Keeping vigour high can be achieved by fertilisation, watering and mulching, while phosphite sprays and/or soil drenches to stimulate tree vitality are also recommended. If the tree or shrub succumbs to the disease and dies, it is necessary to remove and burn it. When removing it, either remove the stump, or cover these with soil to smother the fruiting bodies and prevent further infection.

A guide to green infrastructure
WITH GROWING AWARENESS OF THE IMPACT OF CLIMATE CHANGE, THERE IS NOW A MORE ENLIGHTENED PLANNING RESPONSE – AND THE ARBORIST COMMUNIT Y ALSO HAS AN IMPORTANT ROLE TO PLAY
t’s impossible to ignore the massive impact our species has had on the environment, from growing evidence of climate change because of the production of greenhouse gases, to the devasting eﬀect of vast amounts of plastic ‘bobbing around’ in the oceans. At last there is now action being taken as politicians start to listen, which can be seen in changes within the planning system. Proposed schemes must now ensure there is a cumulative gain of biodiversity, based on an interpretation of the best available advice, if approval is to be granted. One phrase which now pops up more frequently is
Jonathan Hazell.indd 27
‘green infrastructure’. Green is used to refer to ecology and the environment, and includes wetlands, rivers and canals. You might also hear ‘blue infrastructure’ when solely referring to water. ‘Grey infrastructure’ tends to be an engineered solution for a single problem or function, encompassing buildings, roads, sewers, power, and so on. Natural England talks of green infrastructure as a “strategically planned and delivered network of high-quality green spaces and other environmental features designed and managed as a multifunctional resource.” In simpler language, green infrastructure refers to the parks,
playing ﬁelds, highway verges, private gardens, allotments and cemeteries that surround us. Many of these amenities were introduced by the Victorians for the public good – there was a growing awareness that if people could stay healthier, they could also be more productive at work. As our urban areas are becoming ever-more densely populated, those green spaces are becoming more valuable, and so government policy has shifted to help make towns and cities better places to live and work. So, how can green infrastructure be seen in the planning process? Planners will always seek ustiﬁcation. Take the retention of a single mature oak
tree in a new housing scheme – this could, for example, depend on it being physically linked to other areas of open space, or if it is used as navigation for bats. Roots in the past Green infrastructure may be higher proﬁle now, as are environmental concerns and the impact of climate change, but it is not a new strategy. In the Seventies, ideas were published for a ‘strategic approach’ to landscape planning that would deliver a range of beneﬁts. n the Nineties, the idea of an integrated
Pro Arb | Summer 2019 27
approach to land conservation and land use planning began to emerge in the USA and the UK. In the early years of the 21st century, the UK government published a range of documents that spoke of the beneﬁts of sustainable development and green infrastructure. In 2008, Planning Policy Statement 12: Local Spatial Planning was published, to be superseded in 2012 when the National Planning Policy Framework was ﬁrst published as a response to the Sustainable Development trategy, setting out ﬁve principles of sustainable development. Design-led development We could see green infrastructure thinking in action, and back in the Eighties the design-led vision for development corporations, like Milton Keynes, spoke of strings (links) and beads (areas of special interest) as well as points of connection (links between the grey and the green). Since the Natural Environment and Rural Communities Act 2006,
Understanding planning and ecosystems In 2009, Natural England’s Green nfrastructure Guidance deﬁned ecosystem services as ‘the essential services and beneﬁts that are derived from a fully functioning natural environment, including the management of
stronger policies put the environment front and centre of planning each local authority had a suite of policies that, taken together, deal with sustainable development, underpinning the sustainability of a town or city, and include resilience to the eﬀects of climate change and conserving biodiversity. Stronger policies put the environment front and centre of planning, from policy to development control to enforcement. However, with austerity policies, the translation of the policy’s ambition into the built form is unpredictable.

basic resources such as water, and the sequestration of carbon.’ However, it is not easy to compare and contract the value of diﬀerent species and habitats when it comes to development. Think of the incredibly rare beetles in the oaks at Moccas Park in Herefordshire or the management of a landscape to care for wood white butterﬂies? Arborists will also be aware of this as they need to balance competing interests of trees with society. Does a retained single, mature, oak tree amongst
a development of detached villas provide green infrastructure, or is it simply a sop? ould a designed approach make a better contribution toward a resilient, future-proofed landscape? There can be many challenges, but some may imagine that simply having more trees is a good thing. Likewise, pruning should be about providing a positive beneﬁt and not to be done so savagely that beneﬁts of the tree were reduced. Certainly, many arborists would support more planting and better tree care, but they should be the right species in the right place, as well as being well managed to establish and thrive. Guidance exists on choices that will help to deliver a sustainable landscape. The Tree and Design Action Group (TDAG) has published Tree Species Selection for Green Infrastructure while archam oﬀers pecies election, a guide to informed decisions. Another win would be to be supportive of the retention of older trees in the landscape. The
Ancient Tree Forum has published plenty of well-researched guidance to encourage retention where practicable. Our role can encompass green infrastructure as the advocates for the tree, promoting management as part of a multi-disciplinary approach, based on evidence and learning. So, when we consider green infrastructure it might not always be the obvious. Would the retention of woodland – neglected spaces in particular – provide as much green infrastructure as a well-treed urban street? An isolated oak may give fewer overall environmental beneﬁts than a newly implemented landscape, especially a well-designed one that provides a network of links, threading across a site and linking it to the wider open spaces beyond.

WHAT CONSTITUTES GREAT PRODUCT DESIGN? PAUL DYER HAS THE ANSWERS, BUT AS HE ALSO EXPLAINS, SELECTING THE BEST IN STATIC ROPE CAN BE AN EXERCISE IN COMPROMISE
any of the requirements a rope must meet are achieved at the expense of another desirable property. So, for this reason, published performance ﬁgures do not tell the whole story. t is necessary to dig deeper into the actual design of the rope to really understand why certain compromises are necessary. Material Static ropes are normally made from polyamide (nylon) in order to maximise the energy absorbed in the event of a fall. t is possible to use polyester in some designs, but the dynamic performance is often very poor. Nylon has unparalleled ability to stretch and soak up a fall, but this comes at a price in regard to some of its other properties. ost noticeably, nylon is hygroscopic (absorbs moisture from the air) and is aﬀected by water. This will cause the rope to shrink along its length and become stiﬀer after soaking – some users actually pre-shrink

their ropes by soaking and drying before use. t is possible to combine materials such as polyester covers and nylon cores, but this must be done with caution. f the core shrinks and the cover does not, then sheath slip can become a problem. n addition, low melt point materials such as polypropylene are not allowed by 1 91, the arborist climbing line standard.
level of the core is another compromise highly twisted cores aid drop performance and oﬀer higher elongation, while lower twist is stronger and provides less elongation. A good rope will have an equal (or thereabouts) number of cores
Core tandards allow the designer considerable ﬂexibility with respect to the cores and they can be any si e and construction. n most static rope designs, the cores are the primary load bearing part of the rope. arger cores are faster and therefore cheaper to produce, but they do not give the same ﬁne control over the diameter as smaller cores. Smaller cores tend to produce rounder rope that is more supple and less prone to lumps when bending. Twisted cores are normally in the form of three strand sub-ropes. ike a rope, they should be balanced and should not have a tendency to twist or hockle. t is possible to make a static rope product with single twist cores, but this rope would likely lose performance over time – with the only obvious beneﬁt to doing this being price. The twist
Parameters tested for in BS EN 1891 Diameter Measured at a reference tension of 10kg, average of six measurements – must be between 8.5mm and 16mm diameter. Knotability nsuring the rope is ﬂexible and can be knotted. The internal diameter of an overhand knot must not exceed the diameter of the rope multiplied by 1.2. Sheath slippage Measurement of relative movement between core and cover. This must be below 2% to ensure cover will not bunch up in use. Elongation Simulates the rope ascension load using weights of 50kg to 150kg. Elongation must not increase length by more than 5%. twisted in either direction, this ensures the rope has no tendency to twist over its lifetime. Cover For most designs, the purpose of the cover is to protect the core. There is a balance to be achieved between a thin cover that provides minimal protection, but allows for more load bearing core material, and a thick protective cover that leaves little space for the core. Most static rope designs opt for a 16-plait cover made on a 32 carrier braiding machine (sometimes erroneously referred to as 32-plait). The same machine can also make true 32-plait covers if the carriers are run in a diﬀerent conﬁguration. t is also possible to make a rope with a thicker cover and less carriers; Marlow’s Diablo is an example of a 24-plait rope made on 24 carrier machines, while 40 or 48 carrier machines can achieve thinner covers. To achieve optimal durability, the cover yarns should be twisted. This ensures that any ﬁlament breaks that occur from abrasion will form a protective ‘fuzz’ on the rope surface. Performance To pass BS EN 1891, the rope must meet nine tested parameters. These are often a compromise, as achieving success with one
Rope Climbing.indd 31
parameter may result in poor performance on another. For example, the static elongation with loads from 50kg to 150kg must be less than 5% – a low elongation here results in a low stretch rope that is e cient to climb on. However, it may also result in a high impact force and poor dynamic performance. Rope designers may decide to optimise a rope’s design to excel in one or more of these properties to the detriment of others. Part of the skill is achieving the right balance. This includes the ‘feel’ of the rope, durability and compatibility – the published ﬁgures can only ever tell part of the story. Paul Dyer is technical manager for Marlow Ropes. www.marlowropes.co.uk
ABOUT Marlow Ropes is a world leading manufacturer of specialist synthetic fibre ropes and assemblies including static LSK rope. The range of CE & NFPA certified access and rescue ropes is intended for rope access professionals. As well as semi-static, dynamic and specialist ropes for abseiling, it manufactures and supplies fire and rescue lines that conform to British and European standards. Marlow’s range of rope access products excels in design, quality and performance.
Core/cover ratio This requirement is designed to ensure the rope has a load bearing core and that the cover is su ciently thick to provide protection. Impact force Peak load seen when 100kg (80kg for type B) is dropped through a fall factor of 0.3. Dynamic performance The rope must survive at least ﬁve fall factor single drops with 100kg drop mass (80kg for type B). Static strength without terminations The rope must have a strength exceeding 22kN. Static strength with terminations The rope must have a strength exceeding 15kN. n addition to these, the following parameters are also tested, but there is no requirement to pass. Shrinkage A percentage indication of how much a rope will shrink in service. Mass Rope mass is measured at reference tension, typically calculated and expressed per meter.

here are a number of routes to becoming an arborist, and some ama ing colleges in the K which oﬀer courses covering all aspects – some lasting three years, others just a day. ecoming a student can involve ﬁnancial sacriﬁce, and some may be desperate to put the classroom behind them if they didn’t en oy school. ut, because there are so many courses on oﬀer, and with colleges providing a
bad or dangerous habits, and obtaining work because customers don’t think to ask if they are ualiﬁed (and who then fre uently are disappointed by the standard of work). Starting out The Arboricultural Association (AA) – at www.trees.org.uk – has a useful guide to ualiﬁcations on its website. t then makes sense to check out colleges to see what is on
there are so many courses on offer and colleges offer a vastly different learning environment to school vastly diﬀerent learning environment to school, gaining an education in arboriculture is hugely enjoyable for many. For those who perhaps struggled with nglish and aths, some colleges oﬀer additional help in these areas alongside the arb study – they provide plenty of support to develop knowledge and become proﬁcient. Yet, despite this, there are plenty of individuals, often working as ‘tree surgeons’, who have never taken a course. nstead, they will have learned on the ob, often picking up

oﬀer. roadly, tuition covers from evel 1 for complete beginners, to evel which is aimed at postgraduates. t could be that a local college oﬀers the ideal course, whereas in other cases, it may be necessary to move. A number of the larger courses have student accommodation and bursaries available to help with expenses. Applying early to secure both a place and accommodation is always a wise move, as places will be numbered. or example, Kingston Maurward College in Dorset has
A student scales upwards on his course at Kingston Maurward College around 50 rooms for students, Plumpton ollege in ast ussex can accommodate 203 students, Sparsholt College in Hampshire can house 400, while Reaseheath College in heshire can house 1, . What’s right for you? There is no one si e ﬁts all when it comes to arb courses, and there is no recommended study route. So, some may wonder whether it is worth taking a two-year course, when others

this, there’s the option to take a Level 3 course: the Advanced Diploma, again, either part-time or full-time for a year.
Making the cut – students saw ahead at Capel Manor College (at a lower level) will only study for a year. It could be that work is readily found after a oneyear course, and following this, top-up training can be taken while working. thers may ﬁnd that a two-year course oﬀers far more scope to learn about the sector in depth. Meanwhile, some may opt to study for a year, then decide to study for a higher ualiﬁcation at a later date. apel anor oﬀers the same course either full-time or part-time. Its Level 1 course: Introduction to Tree Surgery Land-Based Diploma, provides training in the practical skills (such as basic tree climbing) and machinery. This is suited to those with no experience, and can be taken over a year, either full-time or one day a week. On successful completion of this, students can then take the Arboriculture and Forestry xtended ntermediate ertiﬁcate ( evel 2) to include more technical training, on either a part-time or full-time one-year basis. Following

pprenticeships on offer The AA’s website also outlines apprenticeship options that are available at a number of colleges which have arrangements to connect with local employers over the apprenticeship period. This would typically be for two years, with study at the college on set days. A new standard was launched in une 2 1 , to make the training better-suited to deliver the skills which employers require. There are advantages in taking an apprenticeship, from being able to earn whilst learning, to gaining work experience, but it can depend on what employers have available and whether the student is a good ﬁt.
its fast track option should make the student employable as an arborist after completion. Most of the training is based on passing the industry recognised PT ualiﬁcations, in areas such as using a chainsaw, felling trees, climbing, using a MEWP and wood chipper, among others. Students are required to have their own PPE, but climbing equipment, chainsaws and tools are provided. Great people, great training Before booking any course, there is no substitute for visiting the college in person and ideally speaking to tutors and other students. Enquiries should also be made into what happens when students have left – have they found it easy to ﬁnd work? Some colleges have excellent connections with local employers and can advise on where suitable positions for college graduates and leavers are available. Laura Daykin, who works in marketing for Kingston Maurward College, says she was taught the basics in climbing by one of the tutors to help her ﬁnd out more about arborist work. “Our instructors had me climbing a tree solo by the end of a three-hour session – they are awesome, and apart from the great teaching, they also work in the industry, as well as teaching, which really helps students.”
There are advantages in taking an apprenticeship from able to earn while you learn to gaining work experience, but it can depend on what employers have available and whether the student is a good fit for the business ome colleges oﬀering apprenticeships, include: Askham Bryan College in York, Capel Manor College, and Cornwall College. Intensive options ome may ﬁnd an apprenticeship restrictive, or perhaps they are older and want to complete training over a shorter period of time, which is why taking a short course may be the best route. Plumpton College is among those oﬀering intensive courses, and
Kingston aurward oﬀers an apprenticeship and full-time courses lasting either a year (Level 2) or two years ( evel 3). t also oﬀers a number of short courses aimed at those already in work who need to boost their skills, such as chainsaw maintenance and cross cutting, stump grinding and aerial tree rigging. Out and about According to Liz Green of Reaseheath College, many students ﬁnd work once they have
completed their studies, while others choose to study arb, forestry or woodland ecology at a higher level. She adds that the variety of study is what appeals to many students, from the practical aspects of climbing, to learning about conservation and supporting the local community with real-life arb projects. There are also trips taken to estates throughout the country to look at tree management as well as going to related events. The most popular course oﬀered at Reaseheath is the two-year Level 3 Advanced Technical Extended Diploma in Forestry and Arboriculture, which features topics such as tree science and woodland management, in addition to all the other core skills required by an arborist. Former student Tom Bithell, who completed the course in 2018, found work as a trainee arborist with the taﬀordshire ﬁrm, Arb Tree

the age of 40 or younger, because they no longer have the re uired ﬁtness, or might have sustained an injury. adlow ollege in Kent oﬀers a full-time, two-year evel 3 Technical ualiﬁcation in Forestry & Arboriculture, which covers aspects such as tree felling and chainsaws, plant and soil science, as well as a skill set sought by employers. Leavers have taken arborist roles, but also work for the National Trust, wildlife conservation organisations, local authorities and landscaping ﬁrms.
Thinking ahead Gaining an education is an investment for the future. t is also worth thinking about courses that oﬀer a breadth of training so that a working life can be both long and fulﬁlling. Those who climb and carry out the most arduous tasks will often ﬁnd they need to stop, usually before
tu ing or long ter ene ts Deciding which college and course is suitable requires a great deal of study in itself, but certainly, many who chose to learn about working with trees seriously are most likely to reap the beneﬁts over a longer and more rewarding career.

Get to grips with the Good Work Plan IF YOU EMPLOY STAFF THEN KEEPING UP TO DATE WITH THE LAW IS IMPORTANT – ALAN PRICE HAS GUIDANCE ON SOME APPROACHING CHANGES
ave you heard of the government’s Good Work Plan? This focuses on the UK labour market’s future and brings changes to employment law. Some of these are to be enforced from 2020, with others already in force. So, if you employ people, then being informed on this matters. The Good Work Plan is the government’s response to the Taylor Review, a project which took place in 2017, that looked at the country’s employment practices to see if change was required. Many of its proposals are now set to be implemented. The aim is to provide workers with fairer conditions and better communication between management and staﬀ. There is also emphasis on more vulnerable workers, such as those on zero hours contracts and those who have less employment protection.
are casual, with a payslip and for those who are part-time, it should show the number of hours they are being paid for.
There is also emphasis on more vulnerable workers such as those on zero hours contracts and those who have less employment protection Some of these proposals may appear less relevant for the arb sector. For example, it will now be required for tips to be passed on directly to the individual – so this could be waiting staﬀ and hairdressers – rather than taken by the employer. However, were you also aware that from April, employers were subject to new payslip regulations? This means that you must already be providing all workers, including those who

Other aspects of the plan include: Statement of main terms From 6 April 2020, employees will have a day-one right to be provided with a document that outlines their main terms of employment. This should be detailed to show information such as, training entitlements, maternity and paternity leave and probationary periods. If you have a standard terms of employment template that is provided to staﬀ, then now is the
time to make sure it is updated if necessary, and this change could well mean a higher administrative burden. Holiday pay The mandatory reference period for calculating holiday pay will also increase under the plan. From 6 April 2020, employers will have to use a reference period of 52 weeks, as opposed to 12, when calculating holiday pay for staﬀ who work irregular hours, or whose pay may vary due to overtime. Ahead of this, employers will need to ensure the correct mechanisms are in place to accurately record all working time, while also reconsidering how regularly overtime is oﬀered in the intervening months, as this may lead to increased holiday pay in the future. The government is also expected to announce a holiday pay awareness campaign.

Agency workers f you use staﬀ from agencies, then they will have the right to receive a key information document, that includes clear details of the nature of the work they are accepting, while the use of the so-called ‘ wedish erogation odel’ contracts will also be banned. This referred to the fact that previously, those who had a permanent contract with an agency, were entitled to full employment rights but not pay, and this meant they could potentially be worse oﬀ than those working directly for a business. owever, from 3 April, agencies will now need to provide such workers with a written statement, explaining that they are now entitled to the same basic pay as a direct recruit after 12 weeks on assignment. More contract stability Another future change will be the right for all workers to re uest a more stable contract after 2 weeks’ service, however, an implementation date for this has yet to be announced. The idea behind this is to allow those in insecure employment – such as those on ero hours contracts - to re uest a more ﬁxed-working pattern, such as agreeing on a minimum
number of hours each week or set working days. t makes sense for employers to consider how they could do this and be ready to hear and decide re uests. t is likely the process will work similarly to the right to re uest ﬂexible
The aim is to stop employers being able to rely on a one-week gap – some ﬁrms would abuse the system by dismissing employees and then re-engage, but at the same time reducing their employment rights. hile
The aim is to stop employers being able to rely on a one-week gap – some firms would abuse the system by dismissing employees and then re-engage, but at the same time reducing their employment rights working – unless there is a strong reason for preventing a worker from doing this, then employers should seek to accommodate such re uests. Continuity of service This will allow workers to establish continuity of service more easily. The ualifying ‘break in service’ is currently one week but will be extended to four weeks from April 2 2 – this means an employee will generally have continuity of service, even if they have gaps in work (of up to this amount).
there are larger arborist companies, many businesses within the sector do not have R professionals working for them, and their processes may be lax – combined with a lack of knowledge. ut, making errors in this area can result in some serious conse uences, and with introduction of more stringent legislation, the government is turning the spotlight on employment practices. This will include stronger enforcement of tribunal awards and increasing tribunal ﬁnes for employers. There is also the intention to ‘name and shame’ employers who fail to employ awards and to make it easier for successful claimants to enforce payment. There will be sanctions levied onto employers who lose a second tribunal, if it’s decided that it’s on similar grounds to a previous claim – even though this may not always be straightforward to prove. The maximum penalty for aggravated breaches of employment rights has also risen from 5, to 2 , .

fit for purpose THOSE WORKING WITHIN THE INSURANCE SECTOR ARE WELL PLACED TO WITNESS THAT ARBORICULTURE IS A RISKY BUSINESS. SO, HAVING THE RIGHT COVER MATTERS, AND IF A CLAIM NEEDS TO BE MADE IT IS VITAL TO HAVE STAYED WITHIN THE POLICY’S LIMITS TO ENSURE IT WILL BE PAID. STEPHEN LEWIS OFFERS SOME EXPERT ADVICE
ven when the risks are considered in isolation, the stakes within arboriculture are high. Falls from heights and working with dangerous equipment, to falling debris, exposure to power lines and musculoskeletal strain are amongst the occupational hazards. This is why risk management and obtaining the right level of cover is of paramount importance for workers

in this sector. In the event of an insurance claim, businesses are expected to demonstrate that they took all the necessary precautions to limit risk and adhered to absolutely all health and safety regulations. erial work ake sure the polic ts The hazardous nature of tree surgery means that workers, particularly those who climb on
a regular basis, are particularly vulnerable to enduring life-altering or fatal injuries. The cost of personal injury claims continues to rise, and past claims following a fall from a tree have been settled in excess of £9m. So, it is imperative that the right level of cover is obtained. Speak to your insurance broker or provider to check if there are any policy exclusions or restrictions, such as height limits on the policy, whether it excludes damage or injury within a particular distance from the tree, or if it stipulates that work should be undertaken in a speciﬁc way. Making a claim is often done during stressful circumstances – this will only be compounded if an insurer withdraws cover because the policy had restrictions or exclusions that were not known to the policyholder. For example, this could happen if a landscaper’s policy speciﬁcally excluded aerial tree work. If an accident involving a fall was to occur, the employer could be left to deal with the claim themselves, putting their business and personal property at risk and at a serious ﬁnancial disadvantage. Therefore, checking the speciﬁcs – and level – of cover should be a key priority. For employers t is also important to check the diﬀerences between types of insurance policies and take advice on what is necessary. For example, there is often a misunderstanding in the industry around the need for employers’
FEATURES | BUSINESS ZONE
liability insurance. There is an assumption that businesses which engage the use of labouronly sub-contractors – which is commonly the case in arboriculture and forestry industries – are not subject to being liable, with many instead opting out of buying such cover. However, this is not the case, as anyone who works under the control of the business, supervision or direction – or anyone using their equipment – would be deemed a temporary employee. It is the responsibility of the business to arrange this cover, where necessary, or they could face prosecution under the Health and Safety legislation for non-compliance with the Employers’ Liability (Compulsory) Insurance Act 1969, as well as dealing with the claim from the injured party should an incident occur. Speak to a specialist broker and familiarise yourself with the diﬀerent policies, from public liability to professional indemnity, and seek advice on whether you would need this cover or if you happen to have any gaps. If you have a claim Risk assessments and contingency plans help to ensure controls are in place, as well as to ensure a uick and e cient response in the event of an incident and create a paper-based evidence trail of health and safety adherence. Furthermore, all workers will be familiar with the task at hand, their individual responsibilities, the associated risks and will be fully aware of what to do in the event of an emergency. The importance of this cannot be overstated when time is of the essence. For example, before commencement of any work, checks should be in place to ensure all
and adjustable lanyards – should meet the necessary safety standards and should not be tampered with or altered. Workers should be fully trained and competent in the use of all equipment and understand the limitations associated with each item’s use, such as height, load, and slack limitations. All e uipment should be ﬁt for purpose, checking for excessive wear, damage or defects before and after every use. Any equipment that is defective should be destroyed or clearly marked as not for use to avoid it being used by mistake. While conducting work in the tree, secure and
checks should be in place to ensure all necessary pPE is worn by workers, and other essentials, such as a first aid kit, whistle and phone or two-way radio, are carried by the climber necessary PPE is worn by workers, and other essentials, such as a ﬁrst aid kit, whistle and phone or two-way radio, are carried by the climber. All climbing equipment – including fallprotection systems, work-positioning systems,

safe attachment, suitable anchor points and considered movement should be top of the agenda, and operations should be continually assessed to ensure they are carried out in a controlled, safe manner.
The aforementioned may seem self-evident and overly prescriptive, but ensuring standards do not slip and creating documentary evidence that all safety procedures were followed will help businesses in the event of a claim. If an accident occurs and the policyholder cannot provide proof that the injured party was shown a site-speciﬁc risk assessment or other supporting documentation, it makes the insurer’s job of defending a claim even more di cult, if not impossible, regardless of circumstances. Policyholders who can demonstrate a diligent approach to health and safety and fully comply with industry and insurer’s standards may also beneﬁt from policy discounts. Of course, working in the arboriculture industry is varied, and each business will have its own complex needs and ways of operating. But, if businesses take a robust, evidentiary approach to health and safety and regularly review their current policies to ensure they are not left vulnerable, they are on good footing when it comes to being protected.

With biochar, 10 to 20% of the carbon goes oﬀ as carbon dioxide after a decade or so, but the rest remains in the soil. Biochar also reduces the harm from nitrous oxide. This is a greenhouse gas, some 300 times more powerful than carbon dioxide and is released by nitrogen fertilisers, which boost growth and are used widely in non-organic farming. If biochar is in the soil, it reduces nitrous oxide emissions by up to 50%. As such, farmers can halve their nitrate use and still produce results as if they were using agricultural chemicals. Recognition for biochar The UK has a target of achieving carbon neutrality by 2050 and biochar has a role to play in this, according a joint report on greenhouse gas removal by the Royal Society and the Royal Academy of Engineering. It’s also considered a critical ‘Negative Emissions Technology’ by the UN’s Intergovernmental Panel on Climate Change. Carbon Gold’s products are also approved for use in organic systems by the oil Association, certiﬁed and approved for use in biodynamic systems by Demeter International and the UK’s Biodynamic Association. ou can ﬁnd out more about arbon Gold and biochar at: www.carbongold.com

The ST8P from Först was recently launched with a petrol engine to comply with the new emission regulations. This is a performance machine, punching out 57hp from a Kubota petrol engine. According to Först, leading manufacturers would not have been expected to promote petrol products 12 months ago, but it is now the order of the day. With the new emissions regulations now in place, petrol is also one of the most cost-eﬀective ways to obtain a quality chipper. This is due to the fact that anything over 24hp with a diesel engine has to have a P ﬁlter going forward, making it a more expensive and complex option. The rst petrol range is highly fuel e cient, oﬀers plenty of tor ue and makes for a more cost-eﬀective purchase.

Thanks to an extra-wide feed funnel with an open top section (providing better visibility and ease-of-use), and an in-feed aperture 2 mm x 21 mm, (that is the biggest in its class), the T 2 T can tackle obs with minimal fuss. f the terrain is rough, uneven or oﬀ-road, the T 2 T TR tracked chipper is the arborist’s machine of choice. esigned for every ob, it delivers outstanding ground-covering performance and e ciency via its two-speed tracking system. tanding as urope’s best-selling sub 5 kg chipper series, the T 23 PA and T 23 chippers are lightweight machines, powered by either a 3 hp riggs tratton anguard Twin petrol or a 35hp Kubota diesel engine, both delivering performance with no compromise on power. eanwhile, Timberwolf’s ‘All the acts, o missions’ campaign, sets the record straight on the Government’s emission reduction legislation tage – highlighting that pre- tage diesel chippers already on the market, including the popular T 23 , can still be used, bought and traded as they always have been. Timberwolf holds the industry’s largest supply of pre- tage , 35hp Kubota diesel engines. This strategic investment ensures customers can continue to purchase from the current range of diesel Timberwolf chippers, including the sub- 5 kg chipper, the powerful T 23 . These will be available until une 2 2 , while stocks last. www.timberwolf-uk.com

I N V E S T I G AT I O N S IAN AND SUE BARNES OF TREE DIAGNOSTICS OUTLINE THE LATEST IN CUTTING-EDGE DIAGNOSTIC EQUIPMENT
ver the last year we have seen several new introductions to our range of nondestructive testing and investigation equipment. Arborists can now make better informed decisions than ever and use tools to help retain and manage trees with defects or decay in high value areas. ArborElectro – new for tomography The introduction of the ArborElectro complements the existing ArborSonic tomography system. It provides cross-sectional information on wood resistance and is ideal for identifying high and low moisture content. It can identify areas colonised and controlled by fungi or areas with elevated moisture content where a tree has responded to colonisation. Detailed information on loading, biomechanics and a safety factor based on engineering standards such as EN 1991 are generated, moving away from simple comparisons between hollow versus intact stem cross sections.

Callipers from Fakopp ArborSonic and ArborElectro systems have been enhanced by the new Fakopp carbon ﬁbre callipers. These can be changed between three sizes in seconds, helping avoid the inaccuracies in images that rely on circularshaped assessments. Fakopp has built on their experience with static load testing, better known as tree pulling. This is widely regarded as the best way to demonstrate a tree’s ability to withstand a forecasted wind load, a system developed over the last 30 years and backed up with thousands of tests. Fakopp has also developed systems that counter the negatives of tree pulling, such as the space required, the need for an anchor and low wind speeds in which to undertake assessments.
DynaRoot and DynaTree The DynaRoot and DynaTree root and trunk testing systems combine onsite wind speed information with detailed tree movement sensors. They use the power of the wind to provide a safety factor based on engineering standards. The DynaRoot and DynaTree systems replace the need for a winch, and can be used as part of a tree pulling system, allowing both static and dynamic testing of whole trees. Arb-Ex – air excavation system The latest addition to the range has been the Arb-Ex, a user-friendly air excavation system. t oﬀers superior control and interchangeable nozzles that enable: power excavation of large volumes of soil, a decompaction nozzle to enable soil improvement, the incorporation of organic material and a ﬁne no le to allow careful excavation, amongst even ﬁne roots. Add an extension or a 45° connector and you have a system that will allow access deep into conﬁned spaces with minimal damage to live rooting.

CHANGING UP TO A CANTER
ROSS WOODLEY, A HAMPSHIRE ARBORIST, EXPLAINS WHY HE’S STAYED LOYAL TO THE MITSUBISHI BRAND
oss Woodley, owner of Romsey Tree Surgeons, is now on his sixth Fuso Canter – a 3.5t vehicle manufactured by Mitsubishi, and supplied by local dealer: Marshall Truck & Van. Romsey Tree Surgeons was set up in 1998, and caters for both domestic and commercial customers across Hampshire, Dorset and iltshire. The team is ualiﬁed to undertake a broad range of services, including pruning and thinning, and specialises in the safe removal of trees, or parts of trees, particularly those which are large and dangerous – often the result of storm damage. The ﬁrm also oﬀers a professional tree survey service to landowners and developers when a tree is located close to the development site, a motorway, a third party property, or if it appears to pose a threat. Romsey is able to advise on the best course of action required and provide a report. Romsey is now on its sixth Canter in a row. Ross says he favours the model’s strength and rugged durability, which owes much to its ladder-frame chassis. “Most of its 3.5t competitors are based on vans, which simply
Commercial Vehicle.indd 65
aren’t robust enough for our operation. But the Canter is a proper little truck. It’s very well built and, as we know from long experience, extremely reliable – I can honestly say that in the 15 years we’ve been running them, we’ve never had a single breakdown.” He continues: “We always send at least two – but often three – men out in the trucks and they travel in comfort and safety. The vehicle’s handling when carrying a full load is also totally reassuring. It sits really well on the road and has a great turning circle, because you sit right over the front wheels. That’s another important attribute when we’re on and oﬀ residential driveways, and at other sites where access is restricted.” The latest Canter 3C13 model has a comfort cab with three seats and a economical 96 kW (130 hp) 3.0L turbo diesel engine. Ross comments: “I buy a new Canter every three years, and always have two at any one time – my
other truck has been on the road since 2015. We don’t do a lot of miles but when I come to replace them, I’m always impressed by their residual values. “I like my trucks to look smart because they double as mobile advertisements for the business. We’ve picked up quite a few jobs over the years from people who’ve seen us out and about and followed up with a phone call.” He arranged for a conversion on the truck so that it has a high-sided tipping body, carried out by Solent Bodybuilders & Repairs, of areham. The ﬁnished model also has a roofmounted ﬂashing light bar. Solent also fabricated and installed a toolbox with locking shutter doors on both sides. A mesh-sided tray beneath the body on the nearside is used to carry signage and other e uipment. The truck is also ﬁtted with a hitch and used to tow a wood chipper. Ross ac uired the van using ﬁnance from ercedesen inance, oﬀered by arshall Truck an.

KENSINGTON GARDENS FEATURES A DIVERSE RANGE OF VETERAN TREES, PROVIDING EXAMPLES OF THE DEMANDING TASTE OF MONARCHS ACROSS THE GENERATIONS
hat comes to mind when you think of a veteran tree? ’d imagine, for most, the ﬁrst image to appear would be an ancient, gnarled, pollarded oak. This is the archetypal image of a veteran tree in the K – it even forms the AT logo – but this doesn’t change the fact that veteran trees can be any species, si e and age. Kensington Gardens is a Grade listed Royal Park, spanning 242 acres and receiving over 1 million visits a year. The Gardens are known globally for links with . . arrie’s Peter Pan and the ritish royal family. ess known, however, is the signiﬁcant number of veteran trees. Though ﬁrst developed from 1 9, the Gardens were laid out by harles ridgeman at re uest of the ueen in 1 2 . Trends in planting came and went and management techni ues added to the landscape. Throughout all the change, however, the one constant was the veteran sweet chestnuts – 3 of which date back to the ridgeman planting. weet chestnuts are distinctive, with corkscrew-like bark splitting apart and revealing the wood beneath. The trunk

and crown separate into diﬀerent functional units the heartwood hosts fungi such as Laetiporus sulphureus and Fistulina hepatica, breaking into cubical crumbling woodblocks. They are truly remarkable, and are a living connection to the monarchs of the past. The Gardens are also home to other veteran tree species, with a personal favourite being a ﬁeld maple next to the Peter Pan statue. e estimate this tree is 15 to 1 years old. The tree itself has cavities, basal decay and an abundance of dead wood in the canopy. Recently, we made the decision to fence oﬀ the tree. This was to protect the tree from soil compaction as it is located in a busy area of the park. encing oﬀ trees and re-directing desire lines are sometimes essential in order to promote the trees health and visitor safety. There is plenty of other activity connected to conservation as we identify trees that have potential to be the next generation of
veterans. aproxylic insect surveys will help to understand the habitat potential for invertebrates that are dependent on dead or decaying wood. ur work also involves bringing together tree experts – last year, we were proud to host the inaugural AT ondon meeting in Kensington Gardens. Greg Packman is an arboriculturist for The Royal Parks in London, chair of the London group of the Ancient Tree Forum, co-opted member of the London Tree Oﬃcers Association’s Executive Committee and one of Pro Landscaper’s 30 Under 30: The Next Generation winners.
