SITTING PRETTY – DORCHESTER PARK ARBS’ THRONE CARVING A team of local authority Dorset tree surgeons has created a ‘throne’ seat following the felling of a diseased Tilia. The new seat is in the popular Dorchester open space, Salisbury Field, and has since become an attraction, developing a strong local following and appearing frequently on social media. “It just demonstrates how people are increasingly aware of the value of trees and their important place in all our lives,” said outdoor services manager, Carl Dallison, from Dorchester Town Council. He explained that the mature tree needed to be felled, as a survey showed it had dead wood, cavities and severe fungal infection. “Being in close proximity to private gardens and with a footpath running under the canopy we had little option.” Despite this, the team who carried out the work found that the heartwood was still sound

Nick Collins, arboricultural o cer at orset o ncil, said the arborists who undertook the removal and carved the throne were Mike Hannam, Kieran Baxter and Dan Parry, all AA approved contractors and have worked with the local authority for around 12 years. A replacement Tilia has been delivered and will be planted in the field near to the original tree www.dorchester-tc.gov.uk

WOODCRAFT TEAM WINS ‘TREE SPECIALIST OF THE YEAR’ AWARD Woodcraft Tree Services has won the Tree Specialist of the Year accolade at the Corporate Live Wire Prestige Awards. Woodcraft was set against 150 other businesses in Lincolnshire but won the award in part due to nominations from clients he ta ford-based fir was founded eight years ago by Brett Redshaw, who continues to lead the business. he fir has five er anent sta , and rett said s ccess has come about largely because of his loyal and talented workforce. “Each new person has been carefully chosen and the team is nified in its assion and thirst to expand knowledge and skillset.” Team member Dom Jones commented: “It never feels like being at work and the boss truly values us. We support and encourage each other in the variety of work that we undertake and this makes up for some exhausting days. But the aching feeling at the end of the day still brings satisfaction and stification that yo ve earned that beer.” Colleague Grace Lane added: “Training to be a tree surgeon at Woodcraft is the best job I’ve ever had. The role involves a wide variety of work which means I am always learning new skills. We get on very well as a team, supporting each other both in and outside of work.”
ene ts of in house Many arborists use subcontactors (subbies) but Brett believes his fir s ey strength is in having permanent employees. “Although I understand the reasons behind the subbie culture, a good quality climber is expensive to train in-house and takes years to acquire the level of skill needed. “There are a lot of companies which consist of a manager and a groundie, and then a rotating set of sub-contracted climbers that carry out the actual work. For me, this leads to inconsistencies in the quality of work and a lack of company ethic. “When our clients book us year after year, they know they will always see the same faces and be given a consistent professional level of work.” Brett continued that if he needs e tra sta , he wo ld se those fro fir s that he knows very well.

ASH DIEBACK’S DEVASTATING IMPACT IS CLEAR TO SEE. WITH NO END IN SIGHT, HOW CAN ARBORISTS ENSURE THEY PROTECT THEMSELVES AND OTHERS WHEN MANAGING DISEASED TREES?
t’s the pandemic that far fewer people are aware of. Ash dieback is now prevalent in many areas of the country and it appears inevitable that the years ahead are going to see vast numbers of ash trees die because of the Chalara fungus. The numbers involved and cost of this tree pandemic are phenomenal. There are some 125 million ash trees in UK woodlands and between 27 to 60 million ash trees outside of these, according to govern ent fig res and ash dieback is expected to kill 80% of them. Research led by Oxford University found the cost of the
all of them are negative. While they will have appreciation of the devastating impact of the condition, the disease will also undoubtedly result in more work and allow them to broaden their client base. This could include opportunities to lin with other fir s on larger contracts and to work with landowners, charities and local authorities. So, for example, the National Trust is spending around £2m on felling trees with the disease. Rangers, who are responsible for the charity’s tree care, normally cut down between 4,000 to 5,000 trees annually;
the National Trust is spending around £2m on felling trees with the disease, largely to ensure public safety disease to the UK could be £15bn and half of this (£7bn) will be in the next 10 years. As far as ash dieback is concerned, arborists are a ected in a n ber of ways and not

however, ash dieback will push these numbers up to around 40,000, which may be beyond their current resources. rborists co ld also find they are being asked more for
their professional opinion as to whether a particular tree needs felling. However, this potentially has liability issues. Although no one is saying that vast number of arborists could end up being sued, they should still be extremely careful about the advice they give clients. Where responsibility lies Preventing injury to people, animals or property is the responsibility of the landowner; but not all will be aware of this and so in no uncertain terms, arborists should explain that those a ected by a falling tree could sued for negligence. This does not mean that a felling is always permitted though the e ce tions are if a tree is dead, dying or dangerous.
However, if it is not an emergency and the tree is in a Conservation Area or subject to a Tree Protection Order, then the arborist should tell the owner to contact the local authority for clearance before agreeing to work. Again, if relevant, the arborist should also advise the tree owner that it is also an o ence to da age bat roosts or bird nests while these are in use or being built. It is important for arborists to always keep full records of what guidance they give and to take photographs if necessary. Protect yourself We are now in a more litigious society and also one where reputations can be quickly damaged, particularly on social media. If you are uncertain about

they have trees close to roads and that pose a safety risk. Much depends on where a tree is situated. If it is close to a road, bridle or cycle path, then there is going to be far more obligation. In terms of advice, arborists will want to talk to the client about the tree’s current state of health. Broadly, if 50% or more of the canopy is
ready to handle any challenges that may arise. “We’re seeing an increase in complaints from residents’ associations and other campaigners who, quite rightly, are concerned if trees are being removed. This is why those doing the work should be clear about letting people know, whether directly or via social media, why

Arborists also have a health and safety responsibility to their employees – and dealing with ash dieback removals can be ha ardo s o e trees a ected by ash dieback can be severely weakened and be hollowed out. As such, dismantling them may take longer and involve pruners, taking the trunk down in stages and a bigger hinge. They may be unsafe to climb – those overseeing the work should only use their most experienced people and take extreme caution. It is also crucial that arborists act responsibly when working on

a diseased tree, which involves paying attention to biosecurity, keeping tools, equipment and boots clean and disposing of ash tree material properly. If a tree is to remain in place, then the arborist should remind the owner that they will need to ensure there are more regular inspections, in case the tree becomes dangerous, Still standing Even if a landowner chooses to do nothing, then they could be forced to do so if it is brought to the attention of the local authority. In Wales, for example, it was reported that a growing number of farmers have been issued with Section 154 notices under the 1980 Highways Act. This is where
a ected, it sho ld be s b ect to regular inspections, whereas if 75% or more is diseased, then removal is the most appropriate course of action – unless there is no danger. Indeed, current advice is that ash trees should be felled only for public safety reasons. This is because there is hope that a small percentage of trees may show resistance or even recover. Many farmers and landowners have spoken out about the fact there is government aid to meet the costs of tree removal themselves – arborists may again need to remind them of this. Sarah Dodd is a partner with law fir eachcroft, and says arborists have an important role to play in raising awareness. “Although ash dieback is wellknown in the tree community, many still have no knowledge of the condition or the risks. “They may know that trees can cause subsidence which is a risk to property or have heard about Japanese knotweed, which can be highly invasive. But a severely a ected tree co ld otentially ill someone if it falls.” She adds that arborists instructed to carry out felling should also make sure they are
it is taking place and that there is no alternative – in addition to explaining about any replacement tree planting which is planned. Overall, it’s important to remember that risk levels can change and so can experts’ knowledge of this area. For those reasons, it’s essential to remain fully up to date with best practice.” Further reading Keeping up to date on ash dieback is essential and there are a number of useful resources for arborists.

A PASSION FOR ARB, CUSTOMER SATISFACTION AND BUILDING A LOYAL AND TALENTED TEAM HAS PAID DIVIDENDS FOR WOODCRAFT TREE SERVICES FROM STAMFORD, LINCOLNSHIRE. WE SPEAK TO MANAGING DIRECTOR BRETT REDSHAW Why did you choose to become an arborist? When I reached 30, I’d been working in an environment for years where I spent a lot of time on computers, sitting at a desk and being indoors. My heart has never been in it and I had to either make peace and accept I’d always do it or take a risk and start over. I looked for a job that would provide daily physical and mental challenges, allow ongoing learning and skill development and enough adrenaline to stay interested.
Where did you study arboriculture? I initially took a distance learning course to achieve y evel ertificate in rb, and did chainsaw, felling and climbing courses at Brampton Valley Training, where I realised I loved climbing! This job allows for concurrent development of physical skills and intellectual knowledge. I also started to be drawn into the incredible world of tree physiology. I studied my Level 4 in rboric lt re at ree ife rboric lt re ons ltancy in yston ndrew erly and the Tree Life teaching team have such an obvious passion for trees backed up by a depth of knowledge that is humbling.
ow i ou come to aunch our own rm I started with Willow Tree Services in Peterborough, a brilliant company to learn with. They had a professional work approach and took great pride in what they did, which tied in with my work ethic. I left because I needed to feel in control of my destiny, develop my own approach and ‘own’ the process. I initially worked as a subbie climber, which sharpens up your skills in a tree, and then established Woodcraft Tree Services in 2012. t was hard to get b siness at first once we d worked for someone, they recommended us, and around 90% of our work remains recommendation and repeat custom. What were your goals when launching Woodcraft? wanted y co any to o er the best service at a fair price and have a ‘heart’. I was surprised by the range of services o ered by companies, but stunned by the lack of regulation and that vulnerable people were taken advantage of by so e n alified and uninsured ‘tree surgeons’. ll sta at oodcraft do this job because we love it. We can

all talk for hours to clients about their trees. There’s such a low level of understanding of basic tree physiology in this country, and this leads to much of the tree ‘butchery’ we see around. By talking to clients about growth and response principals, we can inform them about good tree care. The more knowledge there is, the fewer people will be talked into having inappropriate work done. Is there a type of arboriculture Woodcraft specialises in? e o er all as ects of tree care fro arb surveys to sectional felling. Our specialism would be awkward trees which require a lot of rigging. We have done a lot of large sectional dismantles over listed buildings, graveyards and conservatories. How did you build your team? ta ng is the ost i ortant feat re of oodcraft ree ervices ve 100 confidence in them to uphold our ethos in all situations. Iain has been with us almost from the start. He joined us straight from university having studied Countryside Management and is a passionate advocate of rural life and nature. He’s the calm voice of reason and, although a alified cli ber, tends to r n the gro nd sta Dom has been with us four years and is lead climber in my absence. He’s astute and forward-thinking and has increased the e ciency of o r wor sites since oining e has introduced new climbing techniques and kit to us and pushed me to embrace them.
piece of kit is a Landover Defender tipper, with h ge o -road tyres and a igershar 11500 winch. It has enabled us to undertake jobs in places we would otherwise not have been able to access and the winch is invaluable for when more than a little pull is required. What do you see as the main challenges for the arb sector going forward? We desperately require some form of regulation. An industry-wide standard must be met before you can call yourself an arborist rather than the current situation where literally anyone can pick up a chainsaw and claim to be one. In terms of marketing, what works for Woodcraft? Word of mouth has always been the number one work generator. We advertise locally too which brings in some new custom, but people are more secure when they get a review of a company from someone they know. The beauty of having an online media presence is that we’re able to showcase our work and skills in a way that you just can’t do on paper. We invested in a DJI Mavic camera drone last year which we aim to use a lot more to capture some climber level video to bring the client into the tree with us a little more. Do you have plans to grow the business further? We’ve been milling timber from trees we fell for a couple of years and are setting up

e on your guard. Arborists in many parts of the UK are having their kit stolen, resulting in enormous disruption to their business and these are just a few recent examples: • £10,000 chipper stolen in Grimsby In November. The kit was taken around 2am and towed away by the thieves. A call for infor ation was t o t for the fir , incl ding for CCTV that might have picked up the crime. • Vast quantities of kit stolen in Hertfordshire. n arborist fir in elwyn arden ity had all its tools stolen just prior to Christmas. The value of the items was around £10K and the haul included dozens of chainsaws, hedge trimmers and blowers. • Selkirk arborist hit by break-in. An arborist in Selkirk was forced to close after thousands of pounds worth of tools were stolen from a yard during a December break-in, with the loss of chainsaws, blowers

and hedge tri ers a neighbo ring fir also lost a wood chipper. Thieves broke through four padlocks and went across two fences. The owner said he believed the total value was around £20K – he was uninsured and said his business was now threatened. If kit is stolen, there is limited chance it will be recovered. There are Facebook pages and forums to help report and reunite items and the police are often informed – to make an insurance claim, this is essential.

It makes sense to keep a log of all your tools, including serial numbers and any marking potential owners to come forward. More often, the items are gone for good. Tools are often valuable and can easily be driven o t co ld be an o ort nistic thief after a chainsaw, or an organised group, perhaps seeking big ticket items like wood chippers that are often shipped abroad or stripped for parts. Items may be sold on to unsuspecting buyers or those willing to buy without asking questions if the price is low enough.

If they are able to claim on their insurance, this certainly helps, but it can be a time-consuming process, particularly if the insurance

So, they may break into premises that have less secure locks and are not alarmed or from the backs of vans. Lockable van storage could prove a worthwhile investment. Meanwhile, not keeping tools overnight in a van will also reduce risk considerably – ensure there is safe storage within your property.

If this had been a short woody stub, it would probably have persisted much longer, rather than falling away first rinci le to understand is the role leverage plays on the failure modes and likelihood of failure of parts of a tree. Leverage is given as the simple calculation: M = F x l (in that bending moment (M) equals the force applied (F) by the length of the lever arm (l); however, there are many other factors such as angle of application of the force
and e ibility of the lever ar that more complex modelling would take into account. As a simple example, the centre of gravity of this long piece of ash deadwood was about 1.5m out from the tree and the weight of the branch is about 10.2kg. This would lead to a bending moment of 100N x 1.5m = 150Nm. This leverage (or ‘torque’) would be constantly acting at the base of the rotting branch. Failure would occur either when the wood decayed to the extent it could no longer resist this leverage – or, as is common, it was substantially rotted and then ‘joggled’ by a strong wind, adding those few more Newton metres needed to cause failure. I’ve once been hit by a piece of tree deadwood that fell from added leverage because a second pigeon came to perch as I was beneath it!

Innumeracy rules rther, find any arborists and arboricultural students are really interested in tree structures and the mechanics of their growth and failure, but they like to learn about tree biomechanics without having to ‘do the math’.
In discussing biomechanics in only loose terms and making use of time-lapse images from my ‘Trees over Time’ (ToT) project, here are some biomechanical cases from which basic lessons can be learnt, including for the maths-phobic.

Crack and decay combo Failure of part of a tree is often caused by a combination of factors. Take the case of a mature tree on a recent housing development that falls over, with few roots coming up from its root plate, after a root-decaying fungus was fruiting at its base for a couple of years. It’s tempting to blame the fungus. However, it was most likely a mix of root damage, root severance, change in soil level, change in soil condition and the root decay fungus that brought the tree down prematurely. Cracks in trees are arguably a sign the component part bearing the crack has failed. But I like to count tree failures when so ething falls o the tree or hits a target, as cracks can be quite often ‘mended’ in trees. Cracked tree forks are prone to failure and, if they do not fail over a few years, it’s common decay also acts in the crack and the junction’s strength dwindles further. The image shows a cracked bark-included junction in a silver maple (Acer saccharinum L.) that had the fruiting bodies of dryad’s saddle (Cerioporus squamosus) growing out from the adjacent dysfunctional area. The middle image shows my orange cow stick going deep into the crack. This combination of a large crack at a main junction and ongoing decay around the crack is not something a tree could readily overcome. Failure becomes more likely in each growing season if the limb still bears foliage – as it was. Perhaps surprisingly, it took six years for this defect to fail, although trees typically produce quite a resilient structure. Failure is often dependent on when storms occur.

First of the gang to die ver five years, ve not only gone back to older photos to create ToT images, but also taken a lot of original photos to time-lapse in future years. On one of my favourite dog walks are a set of sycamores (Acer pseudoplatanus L.) with quite severe basal decay, strung out along the Lune Valley, Lancashire. Their basal defects are due to bleeding cankers at bases, which allowed in decay fungi. The base is decaying away, but I‘ve yet to see any fungal fruiting bodies emerging from any of them. There are nine ‘in the gang’, and I’ve monitored them over the years.
Close-up of crack
o e five years on, the first member of the gang to fall was the one with the smallest stem diameter and a lot of one-sided decay evident. Note it failed below the soil line, with only one rotten root being exposed when it fell. Though not highlighted in many tree decay books, for standing trees, wood decay is often more rapid where wood is situated in the biologically active topsoil layer. Take a fence post driven into the soil 10 years before – you’ll find the ost rotted section is st under the soil surface. nce the bar is o art of a tree and sapwood is exposed and becomes dysfunctional, it rots away like a piece of timber. Active defences against wood decay only occur where there are living cells in the tree – dysfunctional sapwood, ripewood and heartwood are wholly dead materials – and would be ‘timber’ if we dried it out and planked it. The biomechanics lesson is what decay you can see at the base of a standing tree is often more extensive a little below the soil surface, which explains why location is such a common point for decay-led failure in UK trees.

Making an arrest Although a crack found in part of a tree is often a warning of a highly damaged component that is likely to crack further and fall away, it’s possible for a tree to arrest a crack by putting on specialist wood at the crack’s tips. A semi-mature rowan (Sorbus aucuparia L.) growing on a wooded slope has a shear crack developing through the tree’s base, most probably because of minor slope slippage. Some six years on, the tree is still standing. closer e a ination finds some light-coloured wound wood has formed at the apex of the original crack. If we went further and took wood samples from this

area, yo d find the tree has laid down specialised wood – axillary wood – that is far denser than the ‘normal’ wood in the rest of the stem. This axillary wood will have a complex zig-zag wood grain attern a better config ration to prevent a crack propagating through the new wound wood. rees have a range of di erent types of wood they can grow to support their structure, from compression wood and tension wood, to wood of high density and high resistance to cracking. wide range of di erent mechanical actions are matched by a wide range of di erent responsive growth forms to make recovery more likely.

A C-Section Trees can only produce new wood from their outer cambial layer – a limitation, but they make the most of their capabilities. An early mature ash tree (Fraxinus excelsior L.) has a long wound down its stem due to previous bark-inclusion failure four metres above the ground that split the trunk in half for around 3.5m of its length, exposing the sapwood and leaving a semi-circular crosssection to that length of the stem. That semi-circular cross-section would have far less bending strength than its original circular shape and so would be vulnerable to fracture, compounded by the ingress of decay organisms into the exposed sapwood. The engineer’s solution would be to project wood growth from the centre of the wound, to quickly recover the stem’s bending strength. But, as there’s no vascular cambium in that location, the tree cannot do this. Instead, the lips of cambium at both edges of this wound are stimulated into
Detail of the top of the crack
growing wound wood, and that changes the cross-section from a semi-circle to a ‘C-shape’. The wound wood projecting forward, proud of the wound, adds bending resistance to the weakened stem. This is an ‘educated’ biomechanical operation – nothing co ld be ore e cient in restoring stem strength, given the limitations of having to regrow from its vascular cambium. Of course, it’s not a sign of discerning tree intelligence; rather, the process of thigmomorphogenesis, which occurs in all higher plants – dictating how tree’s tissues respond to strain for the benefit of its s rvival owever mechanistic in terms of biology, it still looks clever – and shows the sophisticated biomechanical ‘recovery systems’ trees exhibit.

WEATHER PATTERNS ARE MARKED BY RISING RAINFALL AND TREES CAN BE NEGATIVELY AFFECTED. DR GLYNN PERCIVAL EXPLAINS HOW THIS HAPPENS AND HAS SOME SOLUTIONS TO THE PROBLEM
Blackened roots caused by prolonged waterlogging
ver the past few years, the UK has experienced some of the wettest winters ever recorded. Consequently, millions of trees have faced prolonged periods of waterlogging stress. The Environmental Agency is quick to point out that soils remain fully saturated for up to two months, even when the rain stops, and the ood waters slowly drain hile all trees have evolved to tolerate some degree of waterlogging, re eat e tensive ooding will negatively impact their health. What problems are caused? aterlogging can ha en for several reasons such as compaction, poor soil structure, layers of clay or high volume of water entering the soil. In urban environments, drainage is notoriously poor, and trees are often surrounded by impermeable surfaces such as tarmac which funnels water to the ground around roots and prevents wet soil beneath from drying. Tree roots and micro-organisms associated with the root system require oxygen provided by air-filled ores aterlogging fills the ores
Pro Arb | Winter 2021

Flooding around trees in soil, with water preventing this. As the root system and associated micro-organisms are oxygen-dependent, any remaining oxygen in the soil layers is quickly used up and normal function and growth of roots are interrupted. nce o ygen beco es deficient, aerobic soil micro-organisms drop in numbers and micro-organisms adapted to low oxygen levels proliferate in their place. Such micro-organisms are associated with the production of substances toxic to the tree, release of nitrogen fro soil and acidification rolonged waterlogging also in ences root metabolism resulting in the build-up of toxic metabolites within root tissue. Trees do have some adaptations to long-term waterlogging such as producing adventitious roots above the water line and transporting air from above ground through their tissues to the roots; however, tolerance and the degree of such adaptations varies
markedly by species. Trees also vary in waterlogging tolerance between closely-related species and even within species. In general, broad-leaved species are more tolerant than coniferous species. Management practices There are various management practices that can help trees recover. Nitrogen fertilisation has shown ro ise in alleviating ood stress, although not a complete remedy. Improving soil structure, aeration and drainage is a good strategy for a preventative measure. This can be done by air-spading and adding porous materials such as perlite or biochar. Meanwhile, installing a drainage system is another option. Dr Glynn Percival is a plant physiologist/ technical support specialist at Bartlett Tree Research Laboratory. www.bartletttree.co.uk
INSURANCE IS ESSENTIAL FOR ARBORISTS, BUT HOW CAN YOU TAKE OUT THE RIGHT POLICY? NATALIE CARR, A BROKER WITH SPECIALIST SECTOR KNOWLEDGE, PROVIDES GUIDANCE
rborists have a range of specialist needs when it comes to insurance, and one which needs to be addressed first is the height at which they are working. Most policies will have restrictions on height, something arborists will often need some g idance on fro their bro er t can be di c lt to assess how tall a tree is, but if over the maximum permitted height, as stated on the policy, then they may not be protected. If there is compliance with other insurance requirements, such as having all the necessary legislative training and the ational roficiency est o ncil ertificates or the e ivalent we do not put a height restriction on the policy. Again, providing such information is available, then re i s are often a ordable Making savings Arborists with more experience will be able to lower premiums. If you have a low loss ratio, with few claims, this too will be a factor. or ing with trees is ha ardo s the a or incidence rate is higher than the construction industry. Risks include lone working, chainsaws, working at height, working near to power lines, working with machinery and on steep ground. Unfortunately, there are relatively few insurers in the sector because of the higher risks, with many not willing to quote at all. What about tools? Arborists rely on their tools and it is important to have the correct cover for other risks such as hiring tools, storing equipment, using machinery (whether hired, leased, or owned items) theft or damage. Tools or equipment must be correctly stored as per the policy or this may result in the insurer refusing to pay a claim. Equipment can be better protected by postcode marking using either visible marking pens or invisible markers. We also recommend taking photographs of your equipment.
When tools have to be left in a vehicle overnight, they should be stored in a locked tool vault, and the vehicle parked in a well-lit area close to your home and, if possible, the most expensive items removed. Be sure your policy includes the right cover for this. A further point to be aware of is that putting photographs of your tools in use, as is common on social media, could result in some unwanted attention. Why use a broker? An independent broker like H&H is your ‘trusted adviser’. We look across the insurance ar et to find the right cover and s end ti e understanding your needs. We are not tied to one insurer and so have more options to ensure you obtain the best insurance. A further key issue is having an in-house claims department, which acts on your behalf. You have support throughout the process and if we do not agree with the insurer’s decision, then will challenge this. Some covers such as Motor or Employers’ Liability are mandatory, but you should always a e s re yo have s cient blic iability in lace too altho gh not a legal re ire ent Arborists invariably come into contact with the public and so this insurance protects you and yo r fir in the event of what co ld be enormously costly legal action. We also focus on reducing risk via our inhouse H&H Safety, which provides guidance on improving work practices and implementing health and safety protocols and standards. Insurance matters, but it will not raise standards alone and so safety and best working practices must remain at the forefront.

TPOs and more – an arb’s guide to the law
VIEWS JONATHAN HAZELL
JONATHAN HAZELL EXPLAINS TREE PROTECTION ORDERS AND THE LAWS AROUND THEM
ree Preservation Orders and Conservation Area regulations can appear complex, but arborists need to understand the law in this area. Of course, in complex cases, there’s no substitute for taking case-s ecific advice fro an expert; but having some general knowledge can ensure you understand the basics and avoid work that contravenes the law. Origins of tree protection law We need to look back to the dark days following the Second World War and subsequent recovery plans. The foundations of our current planning system can be found in the Town and Country Planning Act of 1947, brought in by Clement Attlee’s government, while a second milestone, the NHS, followed in 1948. The 1947 Act made the need for planning permission a legal requirement – ownership alone was no longer considered s cient stification for develo ent The planning system was overhauled and new local planning authorities given wide-ranging powers, including in paragraph 28 of the Act, which is a tool for
Pro Arb | Winter 2021
Jonathan Hazell.indd 24
“the preservation of trees and woodlands in their area”. The Act states: “If it appears to the local planning authority that it is expedient in the interests of amenity to make provision for the preservation of trees and woodlands in their area, they may for the purpose make an Order (in this Act referred to as a “tree preservation order”) with respect to such trees, groups of trees or woodlands as may be s ecified Changing times In the intervening 74 years, the phrase “expedient in the interests of a enity has evaded definition, and so arboricultural consultants have needed to work around this. Beyond this, there have been
in 1950 to 66.4 million in 2018, which has impacted the housing market. Other environmental factors include the realignment of our economy, shifting from manufacturing to services, leading to changes in employment. Far more understanding of ecology
Far more understanding of ecology has emerged, as has knowledge of the climate change damage many changes where adaptation has been essential. Notably, a big increase in the UK population – around 50 million
has emerged, as has knowledge of the climate change damage. Town centres have changed with the shift from the high street to online.
We have more understanding too of o tdoor s ace benefits to hel mental and physical health. What a TPO means Tree Protection Orders are often misunderstood, as is their level of rotection he sole stification is that the tree, group of trees or woodland adds to public amenity. The guidance to the current regulations states at paragraph 7: “Orders should be used to protect selected trees and woodlands if their removal wo ld have a significant negative impact on the local environment and its enjoyment by the public.”
The purpose of the TPO is to sustain public enjoyment of the local environment, and not to frustrate development – though that may be a consequence. The order must “be able to show that protection would bring a reasonable degree of public benefit in the resent or f t re Severe penalties To work on the tree without prior written approval from the local planning authority can prove a costly mistake and a criminal o ence ines of to 0,000 can be levied in a Magistrates’ Court and if a case goes to trial in the Crown Court, there’s no limit. The co rt will ta e any financial benefit which has resulted, or likely to res lt, when setting the fine A second misconception is that a TPO prevents any management; but a TPO can be used to promote good management to sustain the tree, and stification can be ade to remove and replace it. A TPO can also be used to prevent unsuitable tree management proposals. A third misconception is that the TPO transfers responsibility and liability arising from the tree to the local planning authority. While the tree contributes to the public amenity, ownership remains with the landowner. Owning property where there is a protected tree carries responsibility, and if the tree has continued to grow and the owners are now much older, it can be a considerable burden. Pressures on tree o cers ree o cers st ta e into the account the law and assess the wider environmental value. They are also now expected to be ecologists, even though it’s a distinct profession. What is more, local authorities have often adopted climate change strategies, and this can in ence decisions
Jonathan Hazell.indd 25
What about Conservation Areas? Conservation Areas provide a lesser degree of protection for trees and are relative newcomers, achieving legal status under the Civic Amenities Act of 1967. The Conservation Area seeks to protect the overall quality and special interest of the neighbourhood or area as a whole. Their reason must be stated in an appraisal document. The planning authority must be notified if there s an intention to prune or remove a tree with a stem diameter in excess of 75mm, or slightly larger, in a forest thinning o eration o stification is required to explain why the work is proposed, unlike with a TPO. If the work is reasonable and does not detract from the character of the area, then the authority may tell the applicant work can go ahead. If not, the authority can serve a TPO. There is only space here to provide a brief outline of tree protection issues; but even though it’s encouraging to see more people showing appreciation of trees, this
is not always the case – some still o t the law he conse ences of this, whether a fine for the landowner or censure for the arborist, can be extremely serious.

eing an arborist means you’re productive all day. Therefore, it’s evident that your protective clothing will get worn and dirty; however, it’s important to keep your clothes clean and safe to wear, especially when they’re regularly exposed to sweat and oil. To ensure the safety of yourself and your PPE, follow Husqvarna’s top tips on PPE maintenance, including washing, repairing, and choosing the right materials for your line of work. Keeping your protective clothing clean and safe results in optimum protection, and also ensures their functionality. The chainsaw protective layer in chainsaw trousers and boots works by releasing long strands of fibre to halt the chain fro t rning f these fibres are dirty from mud or tree sap, then the protective qualities can be reduced, and frequent washing can revent the rotective fibres becoming clogged. On the move To get to your workplace, you often have to tackle any number of obstacles. You climb, you jump, you stretch and twist as you make your way through brushwood and water, over rocks and slopes. That’s why your protective wear needs to provide you with more than just safety. It needs to follow your every move. It needs to be as light

Can you repair your PPE? In addition to keeping protective clothing clean, arborists must check for heavily worn areas, plus, damages or tears in the fabric. The protective functions may be seriously reduced if repairs are not carried out properly. In the event of a tear, or other damage, it’s essential to be aware of the following: • If a repair to the outer material is being made, do not sew into the protective material as this can reduce the protective functions. • Damaged outer material must be repaired immediately in order to prevent the protective material becoming damaged. • The garment should be scrapped and not used again if the protective material has been: damaged, incorrectly washed, or altered from its original shape. dhesive st not be sed when carrying o t re airs as it ay a ect the protective material and reduce its protective qualities.

companions YOU’VE PACKED THE TOOLS, BUT DON’T FORGET THESE ABSOLUTE ESSENTIALS FOR WHEN YOU’RE ON THE WORKSITE
Protect with a Simarghu trauma pack
Accidents can happen and this is why a well stocked trauma pack should always travel with you – it could even be a lifesaver. This one from Simarghu is a ‘best on the market’ version and was designed with input from medical professionals. It comes in a foldout design and contents include a Celox haemostatic dressing for rapid blood clotting in the event of an arterial bleed, a military-grade haemorrhage control bandage and new, improved combat application tourniquet. The pack can attach securely to an arborist’s harness and features a MOLLE System that allows it to be easily detached in the event of an emergency. The addition of a lanyard ensures that if the pack is dropped, it won’t fall to the ground when working at height and will remain constantly accessible. The trauma pack is distributed by specialist wholesaler Workware and is available from Honey Bros, FR Jones and Son and Forest and Arb. www.honeybros.com www.frjonesandson.co.uk www.forestandarb.com
Cover biosecurity basics with Sorbus International
The importance of hygiene has taken on a whole new meaning with the impact of the pandemic. However, even before this, many arborists were well aware of the need to have stringent procedures in place to avoid risks such as spreading pests and tree diseases. For those looking for an introductory biosecurity kit, this ‘lite’ version from Sorbus International is a good starting point. It was developed in consultation with the Forestry Commission and is a scaled down version of the provider’s full biosecurity kit. Whether in an urban or a remote rural location, the kit will prove equally useful and it comes contained in a drawstring bag. Contents include a 250ml spray bottle, a 1L collapsible bottle, a long handled brush, Bootbuddy boot cleaner, hand sanitiser, nitrile gloves and 50 biohazard wastesacks. Cleankill and/or Propellar disinfectants are available to order separately. www.sorbus-intl.co.uk

Stay cool with Makita
The latest addition from Makita’s DCW180Z 18V Cordless Cooler and Warmer Box. Arborists will be well aware that chilled drinks and hot food make eating on the go far more enjoyable and the handy box is powered by an 18v LXT battery, with two 18V LXT battery ports – this allows two batteries to be attached in series for extended operating times. When the first battery is depleted, the unit automatically switches to the second. It can also be powered via 240v mains or with an in-vehicle 12v/24v AC socket. When set at 5°C (normal fridge temperature) the cooler will run for up to 17 hours with 2x 6.0Ah batteries. It can hold approximately 30 cans, or 15 x 600ml water bottles and includes a bottle opener. It can operate at two warming settings of 55° and 60°, with five cooling settings of -18°, -10°, 0°, 5° and 10°. The box has 100mm wheels and a pull handle for convenient transport with side grips for lifting as well as a shoulder strap. It is highly durable for outdoor use. There is also an LED display, to provide users with temperature and battery levels and easily changeable settings. www.makitauk.com
