The “Find an Arborist” campaign has been championed by Total Arb, and supported by the HSE and IOG, in order to raise public awareness of the importance of using a qualified Arborist. The initial response has been successful in highlighting the professional skills required when dealing with trees in our urban environment. However, we now need to move on and increase our campaign to involve more tree professionals and enhance public understanding of the importance of the professional Arborist when dealing with trees. The greatest problem to overcome is to raise the value of the tree and how it impacts on all aspects of our lives. We all take trees for granted; they are all around us and act as a backdrop to all our lives. If we step back and look at the influence that trees have on our wellbeing, then our complacent attitude towards trees will change. The importance of trees in our environment can be paralleled directly to the increasing concern with rising global temperature through CO2 emissions. At long last the governments of the world are taking notice of the potential dangers facing our civilisation through global warming, which has resulted from our apathy towards our natural environment. At the heart of this dilemma is our relationship with trees, both on a global and local level. On the global level it is only through governmental pressure that the destruction of the world’s rain forests can be halted, but it is through our voices that the message will get through to our elected leaders. However, it is on the local level that we can really influence public attitudes towards trees. The Arboriculture Industry is the provider of knowledge and skills to this natural environmental asset, but we must raise our profile amongst the general public. We must become the first stop for advice and expertise whenever trees are involved.

Expanding the Umbrella When we look up in the dictionary the meaning of Arborist, we find that it is a person who works with trees and shrubs. In days gone by this would just have meant a tree surgeon whose main work was only concerned with cutting down trees. In modern terms there has been a shift in skills required, particularly with trees in the urban environment. Today’s Arborist needs to be multi-skilled in order to deal with the vast range of factors affecting tree life in the UK. In nature, the growth of trees is easy, with seeds provided from the tree finding their way to a new site, when if conditions are right, the seedling will take root and the tree will grow. However, in our new urban environment the growth of trees is dictated not by the law of nature but by our civil laws and amenity needs. This brings into the equation the numerous other professional skills which are required under the umbrella of arboriculture. The life cycle of the urban tree is now governed from the initial choice of the type of tree, through legal controls ranging from their position and form of growth, right to their protected status for development and removal. With an increasing amount of regulation coupled with the range of professions involved throughout the life cycle of the tree, it will be up to the Arborist to link and manage all these differing constraints and agendas. Through Total Arb we will champion the profession of the Arborist and promote our aims and skills into the public domain, but we need your support.

The London Plane Tree Hugh Barnes
The London Plane Tree is an evolutionary accident which resulted in a tree which seems to be custom made for the city environment it was named after. The London Plane (Platanus x hispanica but also known as Platanus x acerifolia or Platanus hybrida) is believed to have originated from a happy coincidence, when a Oriental Plane (Platanus orientalis) was planted near an American Plane (Platanus occidentalis) in the Tradescant nursery gardens in Lambeth in the early 1600’s, when plant collecting of foreign species was the new hobby for the gentry. It is documented that both these species were planted in the nursery and obviously nature took its course! The first documented description of the tree is found in1670 from the Oxford Botanical Gardens and it is from this point that the London Plane found its niche in the London Urban Environment.
The Plane Appearance London Plane trees are tall, stately and with superb round crowns and are excellent specimen trees. Depending on conditions they grow between 20 to 50 meters high and are long lived. The famous Plane tree of Hippocrates found in Greece on the island of Kos could be over 2500 years old. In folklore, Hippocrates reputedly taught his students beneath its’ dense cool canopy. This tree is an Oriental Plane and has a crown diameter of over 12 meters and is possible the largest in Europe. Trunks of the trees are usually straight growing and with high level twisting branches ideal for road side positions. The tree is easily recognised by its bark which flakes away in thin sheets exposing creamy coloured new bark and giving a dappled appearance to the trunk.

chopped down for fuel and young new trees died due to the toxic atmosphere. It was during this period that in the upmarket sections of London, where new squares were set out, various tree were planted and it was the London Plane tree which show a far greater tolerance to this new urban life.
The leaves are usually about 15 cm across, light green in colour with 5 lobes and are borne alternately on the stem. The trees produce both male and female flowers which blossom in May. The female catkins, which are crimson in colour, are found at the shoot tips while the male yellowish catkins are found further back on the stem and are wind pollinated. The flowers form into spherical fruits, usually quite prickly and these remain on the tree all winter. The spherical fruits contain the seeds but these are usually sterile. Propagation of the London Plane is mostly by cuttings.
London Plane Trees and the Urban Environment It has been suggested that half of the trees in London are London Planes. To be this successful in such a short evolutionary time, what makes this tree so successful in the urban environment. London today is far cleaner in air, water and general pollution than at any time over the last 300 years. However, during this earlier period the level of pollution was not only bad for the human race but also for the plant kingdom. Most existing trees were
One of the biggest pollutants during the last 300 years has been the soot in the atmosphere which helped create our great London Smog, which killed thousands of people. In the same way as this smog killed people by affecting airways and lungs, in plants the soot blocked the stomata on leaves and pores on the trunk, effectively suffocating the plant. This was made worse by the sulphurous content of the soot which also created an acidic wash which further damaged cells. The London Plane had a distinct natural defence advantage to this atmospheric attack through two main factors. The first was that the trunk of the tree would regularly shed its bark, thus cleansing itself of any soot build up, thus limiting the damaging acidic affect on cells within the trunk. Through limiting damage to the trunk the nutrient and water flow was maintained, thus keeping the tree essentially healthy. The second factor is that the leaves have a thick shiny surface which does not easily permit pollutants to stick to their surface. Furthermore, the shiny surface being very smooth means that it is easily cleaned of any sooty build up every time it rains which, as we know, occurs regularly in London. With clean leaves, transpiration was maintained and the London Plane was able to flourish compared to many of our native species. The London Plane has further distinct advantages, through its tolerance of a

vast range of soils and root disturbance. The tree will survive on reclaimed industrial sites and in disturbed soils, and will tolerate very dry, saturated or compacted soils. It also seems to thrive in restricted root spaces which again give the London Plane its urban advantages. Finally, it has been noted that the London Plane has a high survival rate when its roots are damaged, making it the perfect London Tree. The range of the London Plane is throughout the south but particularly in the southeast of England where the higher summer temperature best suits its requirements. The lower temperatures found in the midlands and the north restricts its summer growth and the species does not attain its potential. It seems the London Plane was created specifically for London.

The wood from the Plane tree is known as “lacewood� in cabinet making, due to the delicate lace effect of the grain. In colour it is similar to beech, reasonably hard and fine grained. It is used in decorative panels and in inlay work and when polished, gives a distinctive effect. It is not used in general woodwork as the sap wood is particularly susceptible to woodworm and is not weather resistant. In folklore, the Plane tree carries medicinal properties both through its leaves and bark. A poultice of mashed leaves applied to the eyes is said to relieve eye inflammation and conjunctivitis. When the leaves are mashed to a cream it can be applied to wounds as an antiseptic. If the leaves are boiled for 10 minutes the cooled broth was sipped regularly to treat diarrhoea in times gone by. Finally when the bark is boiled the resulting broth can be used to gargle which reduces the pain of toothache.

The Forestry event of the year
The APF International Forestry Exhibition Ragley Estate, Alcester, Warwickshire 21 -23 September 2006
Hugh Barnes APF 2006 is the arboriculture event of the year and has a huge amount to offer the arborist this year. It has always been the place to look at new machinery, compare the latest models side by side and strike a bargain. There is never a better time to secure a good deal whether you are in the market for a new chipper, chainsaw or a climbing rope. Our demonstration circuit is longer than ever and there is not a chipper or stump grinder made that will not be exhibited at the show. There is over 2 _ miles of working machinery to look at and 230 exhibitors! The technical updating aspects of arboriculture increase with each Demo and this year is no exception. There is a wealth of technical demonstrations and opportunities to catch up on the latest developments. Stihl and Treevolution will have their ever popular climbing demonstrations as will Honey Bros. Demos will be
running throughout all 3 days and are situated at point 2200 on the circuit. The Tree Climbers Forum will again be there with the chance to discuss and chat through problems with the experts. Arbor Venture will be running climbing demos at point 450 on the circuit. The Health & Safety Executive in the form of the Arboriculture & Forestry Advisory Group are running a seminar on Friday 22nd at 10am in the seminar tent on general arboricultural safety matters. Once you have had your fill of technical updating you can relax with a beer and watch the pole climbing competitions sponsored by Husqvarna, the European Lumberjack Championships sponsored by Stihl and UPM Tilhill, and the International Chainsaw Carving competition sponsored by Echo or watch the extreme mountain Biking demonstrations sponsored by MDL
Ltd. If you are interested in entering the pole climbing or chainsaw carving get in touch and we will send you the relevant application forms. We have 4 arenas this year and more competitions and displays than ever before. You can even have a go on a purpose built mountain biking course. The show grows each time and you will be hard pushed to see it all in one day. We have good value 2 day tickets available. This year we are also able to take credit card payments to make purchasing tickets even easier. Full details of the Exhibition, maps, list of exhibitors, accommodation details, ticket forms etc. are all on the web site. If you have any other queries just contact the office, we are here to help.

Chainsaw Starter Maintenance Ian Morgan
Chainsaws are brilliant - until you canâ&#x20AC;&#x2122;t start them. All petrol powered chainsaws are started using the recoil starter cord technique. This involves repeated sharp positive pulls on the cord in order to turn the engine over to a speed where it can start. It is inevitable that through this controlled pull the whole mechanism will wear and require regular maintenance. The maintenance of the starter mechanism is relatively simple and all chainsaw operators should be able to carry this out.
What this article aims to achieve is to illustrate these simple service tasks and keep your saw running. A length of spare cord in your toolbox at a cost of little more than a pound and even a spare recoil spring can save you the loss of a days work.
housing (photo 4) using a screwdriver. You can then allow the pulley to unwind under the tension of the spring until the pulley stops. If you are replacing a snapped cord or the recoil spring has snapped the pulley will have already lost its tension.
Stripping the recoil starter system
The pulley is now removed from the housing by removing the spring clip by levering it sideways (Photo 5). Next remove the washer, this will allow the pulley to be lifted off the centre spindle (Photo 6).
The starter mechanism is removed by unscrewing the 4 retaining screws and lifting the complete assembly off the machine (Photo 3). Make a note of the individual screw locations as you may find that some may be longer than others.
Photo 5
Photo 3
Photo 1 One frustrating reason for not being able to start your chainsaw is when the cord snaps or the handle pulls off the starting cord. A snapped cord is purely down to poor maintenance, wear on the cord is easily identified (Photo 1) and should have been changed sooner. A similar problem occurs when the recoil spring snaps, this again can be down to incorrect tension on the spring. If the spring tension is worn or incorrect the starter handle will hang down at the side of the machine (Photo 2).

Photo 4
Photo 6 If the recoil spring is being replaced, this should be removed with great care as it will still be coiled inside the housing, try to release the tension slowly or the spring may jump out and can cause damage (Photo 7). It is highly recommended to wear eye When replacing a worn cord from the recoil pulley care should be taken as the cord will still be under tension. Pull approximately 1 foot of cord out from the housing using the handle and place your thumb on the white pulley to prevent it rewinding. Lift the cord out from between the pulley and the

protection for this operation. The new spring, depending upon make and model, will be either in a cassette form (Stihl) or bound with a retaining wire which is removed during installation (Husqvarna). With the cassette model the cassette and retaining hook, (pictured at the top of Photo 8) are lined up and simply pushed squarely down into the housing. With the wire bound model, the new spring is carefully placed on the housing in its correct position and then carefully but positively pressed into place. The binding wire will be pushed off the spring as it is pushed into the casing recess. Photo 8
If just replacing the cord, the old worn cord can be cut from the housing making sure to remove the old knot from the pulley. The featured handle is designed to reduce the stress and shock placed on the hand during starting with a built in â&#x20AC;&#x153;spring shock absorberâ&#x20AC;? (Photo 9). To replace this, prise off the end cap and push out the Photo 9
assembly using the old cord. Using a screwdriver lift the knot from out of the plastic sleeve and remove the old cord. Your replacement cord should be of the correct length and diameter. You should refer to the operatorâ&#x20AC;&#x2122;s manual for this information. Once you have the correct cord you need to form a point on one end to make it easier to insert it into the pulley. This can be done by heating the end of the cord until it is molten and then using a gloved hand roll the end between your thumb and index finger to form the required point (Photo 10).
Total Arb August 2006
Photo 10
This is now inserted from the edge of the pulley until it appears at the side where it can be pulled through enough to tie a simple overhand knot which is pulled back into the pulley to prevent the cord pulling out. Before attaching the handle you must pass the cord through the hole in the side casing from the inside out. Replacing the handle is a reverse process, pass the cord through the bottom of the handle and then through the plastic sleeve which eventually will sit inside the handle. Another simple overhand knot is then tied at the end of the pre-measured cord and pulled into the plastic sleeve (Photo11). This sleeve is then pulled into the handle and the cap replaced on the handle. Photo 11
Now, replace the pulley over the spindle so that the pulley locates onto the curled end of the recoil spring. If you rotate the pulley backwards and forwards you will feel it drop into position. You know it is in position as when you rotate the pulley clockwise you will feel tension against the spring. Now replace the washer and the plastic pawl and finally the spring clip (Photo 12). Eye protection is advisable
from the pulley between thumb and finger then rotate the pulley clockwise to gain tension. You will feel the pulley becoming more difficult to turn after each turn, as more tension is applied. Approximately six turns should give enough tension to rewind all the cord onto the pulley. After your six turns, place your thumb on the pulley to prevent pulley rewinding, whilst you pull all of the cord out of the housing using the handle. Whilst holding the cord taut, slowly release your thumb pressure and allow the cord to rewind into the housing. You should have enough tension on the spring so that the handle sits upright and does not hang down by the side of the machine. (Photo 13) If your handle still
Photo 13 hangs down repeat the above process but adding one further turn to the pulley. The final check is to make sure there is not too much tension on the spring. The simple test for this is to pull the cord out to its full extent, again stop the pulley with your thumb; you should now be able to turn the pulley a further half a turn in a clockwise direction. Now simply re-install the starter housing onto your machine, tightening the screws diagonally opposite until tight (Photo 14). Photo 14
Photo 12
for this operation, these spring clips can travel many yards never to be seen again! Now, for the re-tensioning process, pull all of the cord into the housing. Hold the cord firmly a couple of inches
When testing the machine without the correct personal protective equipment, make sure that the saw is switched off and the chain brake is applied. Using your selected starting technique, pull the starter a few times to make sure it operates.

RANGER EQUIPMENT OFFERS FLEXIBLE FINANCE PACKAGES Ranger Equipment of Chesterfield in Derbyshire, the sole UK importer of the Teupen range of tracked access platforms, has launched Ranger Financial Solutions to assist its customers with funding arrangements. Ranger Financial Solutions, operated by Rob Scollick, is able to provide highly competitive rates of interest and flexible finance packages using a wide range of funders including high street banks and European finance houses. Commenting on the launch, Ranger Equipment's managing director Steve Hadfield said: â&#x20AC;&#x153;We are delighted to be able to offer this new service which we do so on a purely non-profit making basis in order to ensure our customers have easy access to tailor-made finance packages best suited to their individual needs.â&#x20AC;? The flexible packages available include:Hire Purchase:The finance company funds the purchase and you repay the company over a term that suits your cash flow, anything from one to seven years. At the end of the finance term you will own the asset. You can chose to repay on fixed or variable interest rates and have the option to pay as little or as much deposit as you like. The VAT is normally paid in full on signing of the finance documents, however you can defer the VAT payment for up to three months and in some cases repay the VAT over the term of the finance agreement. In addition you gain the benefits of claiming the capital allowances. Finance Lease:The finance company purchase the asset and lease it back to you in return for rental payments over a set period, anything from one to seven years. At the end of the finance term you have two options: either extend the rental period by paying a nominal fee once a year, or sell the goods and retain a portion of the proceeds. You are unable to claim capital allowances but you can normally offset the rental against taxable profits in line with your accounting depreciation. VAT is added to the monthly rentals. Operating Lease:The finance company purchase the asset and lease it back to you in return for rental payments over a set period, anything from one to seven years. The rentals pay for depreciation only and not the entire capital cost, therefore monthly payments are generally lower than for Hire Purchase or Finance Lease. At the end of the term the goods are normally handed back to the finance company as you do not have the option to sell or own them. VAT is added to the monthly rentals.

TA-DIGITAL MAPPING 0806
20/7/06
16:33
Page 12
The use of Digital Mapping in Arboriculture John Cowling
Digital mapping has been around for some time but the cost and complexity of mapping systems has generally limited their use in arboriculture to organisations and local authorities large enough to have dedicated specialist staff. That could now change, as John Cowling of Pear Technology explains.
Pear Technology have been supplying mapping systems to the farming and rural estate industries for over 11 years, where the users often need to make complex changes to a map but are not IT specialists. Nor do they have large IT budgets! With a few minor changes, the functionality and ease of use of Pear’s farming product, PT-Mapper, now lends itself well to arboriculture.
Why digital mapping?
What does it need?
Think of all the ways in which you could use paper maps to support your business and then add infinitely variable scaling, simple area and distance measurements, ability to print maps or parts of maps at any scale on any size paper, easy visualization of root protection zones, location of problem trees, portability with a hand-held, laptop or tablet PC, simple recording of information, automatic linking of trees on a map to their records, linking to photographs etc. etc. These can result in huge time-saving benefits – less time needed on site, less time preparing reports and summarising work. Perhaps most importantly of all, they enable the arborist to present the client with professional-looking maps, either as hard copy or as emailed images.
As a minimum, you need software that enables you to create, edit, view and print your map and you need a digital map of some kind. You can extend the usefulness of both by being able to link your tree information records to the map, for which you need additional software features.
What are the drawbacks? The drawbacks have been cost and complexity. There are some extremely good mapping and GIS (Geographical Information System) software products available, but they usually cost more than £1000/licence and require a good level of understanding to make use of their capability. For this reason, their use tends to be limited to specialists within larger organisations.
12
PT-Mapper is Pear Technology’s software for map creation, editing, printing and viewing maps and costs £275.00. It enables the user to add information to maps, to print maps or part-maps at any scale. It can work with a variety of map formats which enables electronic exchange of map data with mainstream GIS used by local authorities or other large clients. To turn the map into a true GIS where features on the map can be linked to records held in a database or spreadsheet, Pear have introduced the MapLink product and this costs a further £250.00. Again, the principle is one of simplicity – the user specifies the map file and the data source such as a Microsoft Excel or Access file, and providing the map and the data both reference the same identifiers such as tree tag numbers, the software links the two. This means that users can click on a tree on the map and immediately see the records for that tree. Records can also be selected “geographically” – suppose
for example, you need a report on all the trees in a specific street. Finding these trees from within a table can be difficult, particularly if their numbers are not in sequence, whereas in MapLink you simply draw around the area of interest and the report is created. In digital mapping, there are two cost elements – the mapping software such as PT-Mapper and MapLink and the actual digital map data. There are two basic types of digital map – raster and vector. The raster map is like a scanned image or digital photograph in that it is simply a background picture and so is not easy to edit or modify. An Ordnance Survey 5km x 5km square of 1:10000 data costs about £15.00 per annum so this type of map is relatively inexpensive but cannot be used at scales greater than around 1:1000 because the picture becomes too blurred. The alternative is to use Ordnance Survey’s large-scale vector data. Here the map is constructed in layers – one for buildings, one for roads, one for water courses etc. and because each individual object can be selected, map editing is extremely versatile. The map image remains razor-sharp at all scales. A 200m x 200m (4.00ha) block of urban MasterMap data would typically cost about £40 per annum and a 200ha rural estate about £70 per annum.
Typical Applications Landowners are becoming increasingly concerned about the safety of their trees that overhang or are in public areas. Ragley Estate in Warwickshire is one such example, where Chief Executive Alan Granger commissioned arboricultural specialists Mosaic Mapping to survey their road-side trees. Mosaic Mapping

TA-DIGITAL MAPPING 0806

used differential GPS-based data capture equipment, with an accuracy of about 1 metre, to record tree positions, tag number, species, height, health etc. Following their survey, Mosaic Mapping emailed an Excel file to Pear Technology who, because they had already provided a digital map of the estate, were able to use their MapLink product to transfer in a few seconds all 1500 trees onto the map. Tag numbers are also displayed but because of the proximity of many trees, it took about another hour’s work to re-position the tree labels to avoid overlap. Using Pear Technology’s MapLink software, Alan and his staff can now click on a tree and immediately see the records for that tree. Reports on trees in a selected area can be quickly produced and a comprehensive tree management process is now possible. Adrian Darby has several thousand trees on his estate at Kemerton in Gloucestershire and has recently started to digitally map the trees onto a large-scale Ordnance Survey vector map. Adrian’s paper records already give a grid location for each tree, but it was necessary to translate these into Ordnance Survey grid co-ordinates so that he could then use MapLink to place the trees onto the digital map. For new plantings, Adrian uses a hand-held GPS and transfers the positions automatically onto the map using PT-Mapper. Although it is still early days, Adrian sees digital mapping providing huge benefits in the management process. Earlier this year, Stratton St Margaret Parish Council became one of the first parishes in the country to adopt digital mapping and their immediate priority was to add to the Ordnance Survey MasterMap data the location of all the trees in the parish for which the Council are responsible. For this, their
Total Arb August 2006
Page 13
Grounds Manager John Rendell used an ordinary Garmin hand-held GPS and using PT-Mapper, was able to place tree markers directly onto the map. With an accuracy of 2 – 3 metres, the GPS was marginal in some situations but with his local knowledge, John was able to manually adjust the positions on the map. Again, this work is still in progress but it will give the Council a complete record of all trees for the first time, and because the maps are accessible by other staff, the information is not confined to one key individual.
Summary In each of these cases, getting the tree positions onto a map has just been the starting point. Once this has been done, the benefits of digital mapping over paper become self-evident. Maintenance, planning, archiving, printing can all be done more effectively than on paper and the end-result is likely to be time saved for the arborist. Balance the costs against the benefits of time-saved, management effectiveness and impressing your clients with professional-looking maps and suddenly digital mapping becomes an attractive option.

Hands Safety Hugh Barnes
Keeping those feelings alive Apart from your head, your hands are the next most important working asset of your body. They translate your thought process into work through their dexterity and manipulation. Any injury to your hands severely impedes any form of work you undertake and in the field of Arboriculture your hands are the instruments which allow you to work in this field. Damage your hands and you can say goodbye to any active role in the business. Accidents to hands and arms are quite common, from the small cuts and bruises that happen every day, to the occasional traumatic gash or a broken bone. However, long term exposure to vibration and solvents can also cause debilitating problems with your hands. We may never give a thought to having our hands covered in grease from time to time or the vibration from a chainsaw, but continual exposure can cause problems for the rest of your life. Our bodies have an amazing ability to resist injury and repair damage when it occurs, but the key to maintaining
good health is understanding what causes long term damage, and how to limit it. When we are looking at effects on hands and arms we must maintain a holistic approach, as trauma can affect our whole body and not just the site of an injury. The key is to think ahead, not just on the job we are doing, but in the long term. This will enable us to continue working on the job we love until we want to retire and not when our bodies cannot take any more.
Arboricultural Industrial Injuries In the Arboriculture Industry, due largely to the tools of our trade, when an accident occurs, it can be traumatic. However, we all know the effect of chainsaws against flesh or what can happen if we fall out of a tree. This is the main reason for all the new regulations and training to try and minimise the risk of these traumatic injuries. In this article we wish to highlight the potential insidious long term problems caused by vibration on our hands and arms. The main cause of Hand-Arm Vibration Syndrome (HAVS) is through continual exposure to vibration. In our industry this is
through hand-held chainsaws. Any hand held electric tool is capable of causing vibration but it is through continual daily use that a long term problem may occur. Due to the vast physiological differences between each individual, tolerance to HAVS varies from person to person. A machine may well affect one person but another person on the same machine may have no problems due to handling the machine differently or even using a different grip. Our aim here is to make you aware of the problem, and once warned be on the lookout, if problems start to develop.
Injuries associated with Hand-Arm Vibration The type of injuries caused by Hand-Arm Vibration is generally classified through their effect on our body and areis categorised as: 1. Vascular Disorders where the blood supply to our fingers is damaged, causing a condition know as Vibration White Finger. This is when the blood supply becomes so restricted that the fingers look white and lose all sensation. 2. Nerve and Muscle damage can also lead to numbness and tingling in fingers. A gradual loss of strength, dexterity and feeling are the main symptoms which may be noticed. These symptoms also are found in Carpal Tunnel Syndrome where the nerve sheaf thickens to restrict nerve impulses which can be a direct result of vibration damage. 3. Joint pain and stiffness can also be caused through vibration. These can be put down to the aging process but research has linked enhanced joint pain in Shoulders, Wrists and Elbows due to possible vibration exposure in some industries.

TA-HANDS ON PROTECTION 0806

The first symptoms of HAVS are usually a feeling of “pins and needles” or a slight numbness in the fingers. This may occur after a long session using a particular machine or at the end of the day. Whenever it is noticed it is important to take action. If no action is taken the fingers may become more susceptible to the cold and may go white and lose their feeling for short periods in chilly conditions which previously had no effect. As the condition worsens, the “dead” feeling creeps further down the fingers into the knuckle and finally affects the hand.
Reducing the Risk The basic cause of Hand-Arm Vibration Syndrome is the vibration produced by the machine we are operating. The machine can be powered by electrical, petrol and diesel engines and it is the vibrations they emit, when running and when in contact with the work, that can cause damage. The vibration is measured in frequency of cycles per second called Hertz. It is the low vibration range from 5 to 20 Hz that we can feel which causes most damage and
9:07
Page 19
chainsaws range between 5 to 10 Hz. It is the magnitude of vibration and the time we are exposed that can lead to HAVS. To reduce the risk, an overview must be taken of the machines we use, how we use them and general working practices whilst on the job. Below we detail some of the measures we may have to implement.
Purchasing new tools which have lower vibrations. New designs have greatly reduced transfer of vibration to our hands through new dampers and materials.
Modify existing tools by adding better insulation and/or changing grip position.
Maintain equipment. A blunt chainsaw creates more vibration.
Have regular breaks to limit exposure to vibration. Devise an efficient rotor system to spread exposure time.
Check working practices to see if grip pressure can be reduced. Greater training may be required.
Try and keep hands warm when working as this will aid circulation. Use of gloves just for keeping warm helps keep stable temperature. Exercise the fingers and hands while working again to maintain good circulation.
The key to preventing vibration damage is to know what to look out for. There are numerous telltale signs, which if we are aware of the problem, can easily be resolved before damage will occur. Just keep remembering your hands are your work.

NEW ROLES AND RESPONSIBILITIES
Why would any homeowner employ a professional Arborist to take care of his tree, when the “man with the van”, for a few ‘quid’, will sort the tree with his trusty chainsaw!
An Arborist is, basically, a person who works with trees. However, in our complicated world this is like suggesting that the medical profession is just here to put on a band-aid! The role of the tree in our society is so important that proper care can be a matter of life and death, and not just for the tree! It is the role of the Arborist to ensure the safety, health and the legal position of trees in our urban environment.
The answer is that most of the general public do not know what an Arborist is, let alone what he does. It is a sad reflection on our profession of the lack of public appreciation of our skills and the understanding of trees in our urban environment. We desperately need to raise our profile and provide an instant answer, namely, ‘we can save trees, money and in some cases, life and property’. The answer is in our hands and we must get this answer across to the general public. The “Find an Arborist” campaign has the ambitious aim of increasing public awareness in the need for professional tree care. This is a massive task; if we had the advertising budget of B&Q it would be easy, but with our limited budget we need clever marketing and an effective strategy to spread the word to further our aims. The campaign will succeed given time, and benefit all tree care professionals through new public interest. Greater public knowledge can also lead to an improvement in the health of our nations trees. It is up to all professionals in our industry to spread the word and support the “Find an Arborist” campaign. The “Find an Arborist” campaign was started by the Total Arb magazine. We are still in the early days of the campaign, but we have gained support from the Health and Safety Executive (HSE) and from the Institute of Groundsmen (IOG) for our aims and principles. They understand the value of a professional organised and publicly recognised group to further the role of the arboriculture industry.

There has been a change of emphasis in the preservation of trees. New legal powers have been enacted to define responsibility of the home/land owner to ensure the safety of people and property from their trees both above and below ground. The implication for ignoring these new rules can be financially severe, hence the need for the qualified Arborist to guide and advise on any tree matters. In our new litigious society, the owners of trees must be made aware of their responsibilities. Here are just a few points to ponder:A. It is the responsibility of the landowner to ensure that anyone they employ to work on trees has both public and employee liability insurance. Failure to do so could result in legal action against the land/home owner in the event of accidents at the time of the work or in the future as a result of the work carried out. Further advice is available on-line www.findanarborist.com. B. Failure to check on the legal status of trees (Tree Preservation Orders) can lead to large fines for the land owner for unauthorised work up to £20,000 per tree. Your local Tree Officer will advise you on a great number of tree issues. You can find your local Tree Officer and exactly how they can help at www.findanarborist.com.
‘cowboys’ at work... C. The Landowner is responsible for the damage caused by roots from his trees to adjoining properties and buildings. D. The Landowner is responsible for damage caused by his trees in respect of either branches or the entire tree falling down. The landowner can be held negligent if proper risk assessments have not been carried out on the fallen tree. The “Find an Arborist” campaign is designed to help the general public overcome the above problems and have access to the correct advice from an Arborist anywhere in the country and safeguard our tree heritage. All it takes is to click on-line to www.findanarborist.com and the expertise is at your fingertips. Obtaining and acting upon the correct advice from qualified professionals is the only way to show due diligence has been carried out when dealing with trees on your property. Employ the cowboys at your own risk and only if you have deep pockets.

company details will be entered in 1 of 9 sectors on a map. Q Why will the general public be visiting the website? A Total Arb magazine will be promoting this feature through a number of mediums including the Sunday supplements, local newspapers and the consumer press, especially the gardening magazines. Our aim is to show that proper tree care in all environments can only be achieved through properly trained and qualified Arborist. The area of the site that hosts the ‘find an Arborist ‘ facility will also have a selection of archived articles relevant to domestic consumers and examples of poor tree surgery as well as checklists and advice on caring for trees. Q How will you stop any old cowboy from registering? A To register companies will need to show proof of things such as insurance and qualification. This should prevent the ‘cowboy’ element from getting on the register. We are also suggesting that consumers make appropriate checks before engaging an Arborist, and will be providing a downloadable checklist that they can use as a reference. The registration form also allows companies to list their full range of services, such as fuel wood supplies and specialist fungal treatment. Q How much will it cost? A A launch price of £149.00 buys you the whole package including the magazine subscription. This is far cheaper than any other business locator systems and offers a dedicated stream of browsers directed to the site because they want to do business. Q What happens to all the money? A All the money raised will be ploughed back into the campaign to raise public understanding, education and provide support for the arboricultural industry.

SPONSORS AND SUPPORTERS HEALTH AND SAFETY EXECUTIVE The Health and Safety Executive (HSE) has focused on the Arboriculture Industry over the past few years due to our high injury levels. Alan Plom, Head of Safety for the Agriculture and Food Sector of the HSE recently stated:“Working with trees can be dangerous. It kills and seriously injures many people each year as well as causing damage to property, often at considerable cost to house owners and others. This is often due to inadequately trained and under-insured ‘tree-fellers’, offering to undertake work at ‘cut-down’ prices. HSE therefore welcomes the aims of the “Find an Arborist” Campaign, intended to raise awareness of the public and encourage the use of competent, trained and qualified Aborists, who will use safe methods to carry out their work, without endangering themselves or others.” MARLOW ROPES Marlow is supporting "Find an Arb" to promote qualified professional Aborists.

Giant Polypor and Beech Trees Hugh Barnes
Polypore fungus when its fruiting bodies appeared for the first time on the tree. The large, graceful, 50 year old tree gave no outwards signs of the infection until the appearance of the large bracket mushrooms surrounded the trunk just above the ground. The tree can still look fine but the fungus attacks the deep roots first, then moving on o the shallower roots, which is when fruiting bodies or mushrooms are first noticed. The mushrooms may first appear away from the tree where the infected roots are near the surface. They are brownish in colour and may not be noticed for a number of years as they can be mistaken for general leaf litter. Whenever the mushrooms are first noticed, it is still too late to save the tree. The decay of the root system is too far advanced and the resultant loss of structural strength from the main roots makes the tree very susceptible to being blown over and causing uncontrolled damage.
A Death Knell for a Beech Tree Autumn for nature in the UK is the end of the growing season, and the dead and decaying foliage provides new nutrients for our fungal organisms. However, it is the appearance of some fungal fruiting bodies, or mushrooms,
22
which will signal the imminent death of numerous beech trees. The Giant Polypore (Meripilus giganteus) Fungus, which has a special affinity for beech trees, produces its fruiting bodies or mushrooms in autumn and these, when seen on a beech tree, signals advanced terminal decay of the root system.
The appearance of the fruiting bodies or mushrooms can spell danger for any other Beech tree in the area. The Giant Polypore (Meripilus giganteus) spreads by the release of the spores from its fruiting bodies which are dispersed by the wind. Most healthy trees with intact bark can withstand the spores. It is when the tree has some form of damage, a split in the bark for example, that the spores will grow into the wound and the infection begins. There is no proven control except to avoid damaging the bark to stop spore penetration.
The fungus has no respect for the age or prominence of the tree. Last year the Barnsbury Beech in Islington, London, succumbed to Giant

Spotting the Fungus The main characteristic of Meripilus giganteus is the brownish flattened fruiting bodies which are known as a bracket mushroom. These mushrooms are roughly semi-circular or fan shaped with white gills underneath and arranged as a rosette. Their upper surface has concentric rings varying from light to dark brown in colour. They appear in late summer to autumn. The mushroom brackets can grow up to 300mm and be very numerous or can be found as just one or two individual brackets. The sad point of this fungal attack is that with its appearance near or on the beech tree, the end result is the loss of the tree.

Tree Friendly Root Excavation Techniques Andrew Cowan, ArborEcology, Exploration in Arboriculture
Air Excavators:
In the hands of an experienced arborists using sympathetic skill and care it is possible to expose tree roots with their mycorrhiza still intact. However, it is very important to be aware that persistent use of the compressed air stream in the same locations can dislodge the fine roots and their associated fungi, while it is also possible to cause damage to the root cortex of thin barked species. It is also essential that the air stream from the compressor is filtered to remove the â&#x20AC;&#x2DC;crack oilsâ&#x20AC;&#x2122; released as part of itâ&#x20AC;&#x2122;s lubrication mechanism.
Working on Development Sites:
The controlled and direction use of compressed air, utilising a tool such as an AirKnife, AirSpade or AirPick, enables the practiced arborist to sensitively explore the root system of trees with confidence. The careful and skilled use of compressed air in this way makes it possible to break up and remove the soil from around tree roots, leaving them exposed for inspection or to enable strategic root pruning operations. The tools used convert compressed air from a portable compressor to a directional jet stream by use of specially nozzles fitted to the end of a hand held lance. The finely focused stream of air penetrates the ground to a depth of up to 30 cm and can be aimed to crumble and blast the soil away as fast as the operator moves the tool. Since tree roots, rocks and pipelines are non-porous soil can be excavated quickly with no impact on electrical or gas lines and minimal harm to roots.
24
The use of compressed air excavation tools makes work around underground utilities much safer for operators and trees and where it becomes necessary to excavate a trench close to or under the canopy of a tree, these tools can be used to expose roots that may then be either bent out the way of the trenching work or cut back using target pruning. This reduces the stress caused to trees by preventing roots being ripped out the ground by a mechanical excavator, therefore prolonging the trees life expectancy and enabling the retention of trees that may otherwise have been removed. Using similar techniques it is also possible to explore the rooting area of trees prior to the installation of hard surfaces or building foundations. Where planning conditions, or the arboricultural method statement, specifies the use of specialist foundation techniques such as; pile and above ground beam, pad and beam, or canter leaver designs, it is important to find where the tree roots are so the most sensitive installation can be achieved.
Remediating soil compaction: Soil compaction is widely recognised as one of the most significant stresses associated with trees in urban environments, especially in association with development, while also being an issue in well used parks and gardens. Compacted soils have lost macro pore spaces that normally hold air and water, while also limiting the growth of fungi that form mycorrhizal associations with their roots. This has a dramatic influence on respiration and severe compaction can suffocate a tree.
With the controlled use of compressed air radial trenching out from the trees trunk can improve root growth. This is made easy when the compacted crust can be blown away and replace with improved soil and organic humus. In addition, vertical mulching with the compressed air lance can break through the soil horizons to improve drainage and encourage the development of a more structured rooting environment around the tree. The results of such work dramatically improved soil biodiversity and can have a significant impact on the longevity of the trees.

Review of the Arboricultural Associations Arborists Trade Fair The sunshine made a welcome return this year to the Arboricultural Associations 8th Arborists Trade Fair, which was held once again on the Bathurst Estate, Cirencester on the 23rd and 24th June. Evidence of the growing popularity of the event was reflected in visitor numbers, which have increased steadily over the years to the current show’s record-breaking turn out of over 2000. Whether a first time visitor or show regular there is definitely something for everyone. Exhibitor’s numbers increased again this year to 86 and along with Trade Fair regulars there was an opportunity to visit a variety of new stands, which this year included Alpha Contracts, Always Greener, Anglo American Oil Company, BASE UK, Civic Trees (Glendale), Mitsubishi Fuso, The Tree Care Company and Wood-mizer UK to name but some. Also new for this year was the expansion of the site into the woodland edge which provided Treevolution and Stihl with an opportunity to display to several hundred visitors a tree dismantling demonstration which included both a ‘back to basics’ and a ‘problem solving technique’ session. They also provided a practical demonstration covering efficient climbing techniques. Technical sessions also proved popular again this year and topics up for discussion in the Contractors’ Workshop sessions included; the noise at work regulations, the HSE priorities for action in 2006/2007, and a question and answer session with the AA. Stihl’s Technical centre was once again on hand to provide technical troubleshooting and maintenance advice for those niggling problems. They also, in conjunction with Treevolution, provided demonstrations about ‘rope – fibre, construction and applications’, and ‘Practical marking and inspection of kit’ in accordance with LOLER.
Total Arb August 2006
Also running throughout both days was the tree climber’s forum, where visitors could benefit from expert advice, they also had the opportunity to practice the latest climbing techniques, and try new equipment under the guidance of expert climbers, who could provide additional safety tips along the way. A tour of the show ground provided an opportunity to visit all the big name manufacturers and suppliers to the tree care industry, who travel from far and wide to show off their latest wares. Whatever you particularly needed there was someone who had the product you were looking for, including; wood chippers, stump grinders, chainsaws, rigging equipment, climbing ropes and harnesses, protective clothing and equipment, tools, education and training provision, books, insurance, sawmills and the increasingly popular access platforms. Eye-catching new products on display this year included the ‘sawpod’, an invaluable tool for those who prefer their pruning saws attached to their leg rather than to a harness. Also, the modular ‘stump grinder’ guard, designed to reduce the risk of flying debris during stump removal. A first
chance to view the latest book in the Research for Amenity Trees series ‘Tree Roots in the Built Environment’, a chance to see the TreeRadar Unit on the Fujikura stand at first hand, and for those willing to put their fungi identification skills to the test there was the now infamous Tree Life fungi identification competition, which has become a Trade Fair tradition. This year’s winner was once again Stewart Marshall of Leicestershire County Council, retaining his winning crown for a second consecutive year. For all those brave enough to take part, the solution to the six specimens was 1. 2. 3. 4. 5. 6.
Fomes fomentarius Inonotus dryadeus Fomitopsis pinicola Ganoderma lucidum Phellinus tuberculosus Perenniporia fraxinea.
Trade stands, practical demonstrations, workshops, networking or just catching up with old friends: whatever the reason for making the journey to Bathurst, the popularity of this event continues to grow; this was demonstrated by the fact that, in true arb spirit, the refreshments tent ran out of beer on the Friday!

Richard Livett expands with the
Junkkari HJ500 Chipper Jas P Wilson of Dalbeattie supplies and Richard Livett expands, a perfect partnership! Another large forward step was taken by Richard Livett recently with the purchase of a new Junkkari HJ500 trailed wood chipper to aid his woodfuel operations west of Fort William. It is used in conjunction with his Valmet 8550 155hp tractor fitted with roof-mounted Botex 560TL crane which he purchased around 18 months ago, both machines having been supplied by Jas P Wilson of Dalbeattie. Before the new chipper arrived, Richard was running a Junkkari HJ10 behind the Valmet , which although it proved to be a good reliable machine was not really designed for crane feeding, and the 10" capacity was limiting what he could process. A larger chipper had been on his shopping list for some time, in fact since the purchase of the tractor/crane, so what led to his choice of machine? Richard explains: “Well, I knew that the old chipper was really not the ultimate solution to my needs, so I had been collecting info on what else was around. Basically, most of the other machines on the market of similar capacity (18") tended to be drum-type chippers, of which I am not a great fan. Although they undoubtedly produce good quality chips from almost any feedstock, this is at the expense of being a lot more complicated, with various belt drives and suchlike. Also, I am a firm believer that the easiest way to cut a log into chips is if the blades attack at an angle down the grain - exactly what happens with an angle feed disk machine. With the Junkkari, all the power goes straight into the job of doing the cutting in the easiest way possible, which should translate into higher output. Also, I like the strong and simple general design, not too much to bash!” Chip quality is of course a major issue to anyone concerned with woodfuel, so some thought had to be given to
26
deciding if this would be a problem. “As the blade setup on the HJ500 is essentially the same as my HJ10, I reckoned that I would be able to get satisfactory results, and am relieved to say that this is indeed the case. Of course, if you put trashy old slabs or brash into this machine, you will not get immaculate chips out, but I am generally using round wood anyway so this is not an issue.” To help ensure good quality, the blade orifices are fitted with ‘sliver breakers’ which break up any long material such as might be encountered where a knot emerges from the stem at just the wrong angle. The final factor which led to the purchase was the fact that John Wilson was able to come up with a very good deal on the machine, at the same time as Richard was experiencing a rapid increase in enquiries for contract wood chipping. “It all just came together all of a sudden,” says Richard. “I had been looking to upgrade the chipper for some time but could never quite justify it, then in the space of about a week various tentative jobs became reality, so I took the plunge!” Since arriving, the chipper has been hard at work for various businesses locally, including BSW Timber where a large amount of reject logs were chipped for fuel, also for Woodtherm Fuels which has involved filling a lorry container for a district heating system. The new chipper proved ideal for this as the outfeed is high enough to go over the top which means it can be filled right up to the doors. Possibly the most interesting job so far has involved a ferry trip to Mull, where another woodfuel operation is being set up. Richard takes up the story: “I had arranged to go across on the Friday, so that was fine and the customer over there got what he thought might be enough wood to keep me going for most of the day. He had a good 15 tonnes of wood in the yard, but I had finished it all within three quarters of an hour!” In fact this wood was particularly easy to chip as it was somewhat wet lodgepole pine, which as many folk will know cuts like butter. Even so, it demonstrates just
what this machine is capable of doing with the right power behind it. People don’t really know what to expect, and the reaction is usually to goggle in amazement at the way it eats the wood!” So on a final note how is it to live with and actually use all day? “As far as feeding it goes, I would say it is just about ideal. You can see right into the infeed rollers and the action of the crane is very natural and easy. To get sticks into the rollers you are basically just slewing, which is easier than balancing the dipper and boom to pull stuff toward you as with a linkage mounted machine. The controls are on a wee box in the cab and are easy enough to work, although a minor irritation is having to stop the rollers to adjust the output, as the oil seems to just go the easiest way. I went for the optional feed roller lift, which you rarely need to use but I would certainly recommend to anyone, as it saves trying to grunt big butts in by brute force. The stress control works fine as far as it goes, but you do have to be aware that once the rollers lose their grip of a big stick as it disappears, they cannot stop it, so it is best to manually stop very big pieces (15"+) just before this point and ease them in gently. A minor hassle really, and it is hard to see anything that could be done to get round it. That aside, it is a really great machine which is a joy to use.” The multi functional Valmet 8550 and Botex roof crane are used in most of his operations. “The tractor has retained its 3 point linkage therefore I can tow, fit a linkage chipper or winch, lift big hard woods or use the tractor and crane without a trailer. As the 560TL has a very large lifting capacity it is the ideal tool for my commercial forestry and tree work operations. The 40K road speed ensures that I can travel between my sites quickly and efficiently (30mph is quite fast on some of the local roads.)” Richard would like to acknowledge the financial assistance towards the chipper purchase from the Forestry Commission woodfuel development project and from Lochaber Enterprise.

Promax Acces It was in 2001 that Promax Access were first approached by the joint Forestry Commission and HSE board who were researching ‘The Use and Effectiveness of MEWPS in Tree Work’ (Mobile Elevating Work Platforms). The idea was perfect, the joint research body would actually view suitable machines that were available from all manufacturers, test the machines in real situations and even carry out time trials against climbers on the same trees in order to establish the availability of suitable machines. The thoroughness of this research was reflected in the report finally being published in 2003 after much testing, discussion and deliberation. The outcome was excellent for Promax as they featured highly in the final report, with their 18m compact tracked machine coming out on top.

engineering’ will help to ensure continued use, less down time and an extended working life.
Fortunately in Italy, it is the trailer towing laws that have resulted in tracked machines being developed for many years, as they can be transported on small flat bed vehicles. It is also fortunate for Promax Access that the two Manufacturers which they have represented in the UK for over 8 years have specialised in this field as well as the supply of Fire Fighting Equipment, vehicle mounted and specialist all-terrain machines for over 25 years.
The biggest current decision facing MEWP users would appear to be whether to invest in their own equipment or to hire? Hiring in equipment does offer the versatility of choosing exactly the right machine for the job, whether it is a 12m, 20m or 38m working height and when the machine is not being used, it is off hired and no costs incurred.
This was also great news for a number of the smaller tracked machines in the Promax range, built to the same high quality, sharing the majority of common components and together with industry leading performance. One of the most important factors for tree work MEWPS is the strength of

As just one example of the strong build quality of the Platform Basket range of compact tracked machines, the tracked chassis on the RQG 12m machines which actually weigh under 1,600kg, are rated to over 3,000kg. There is a little doubt that equipment in the Arboriculture sector will endure some tough treatment and this ‘over
A Company investing in their own access platform could spread the costs over say 5 years, which could equate to as little as £97.00 per week for a 12m dual powered compact tracked machine. This cost is much easier to build into general ongoing works, rather than a one off hire cost. Owning your own equipment also means that the equipment can arrive with you and leave with you, so there are no additional transport costs. A Company investing in just one machine would probably hope to cover 80% of their works with that machine, and accept that they will still have to hire in for the remainder of

HUSQVARNA SWEDEN ARE MAIN SPONSORS FOR 2006 WORLD CHAMPIONSHIPS FOR LOGGERS The world’s largest manufacturer of chainsaws, Husqvarna AB, which also includes the brand Jonsered, will be the main sponsor of the 2006 World Championships for Loggers for the first time. “The World Championships are an important event for the chainsaw industry. As a world-leading manufacturer we want to be part of making this year’s championships the best ever”, says Louise Calverley, Marketing Manager for Husqvarna UK. In the tree felling event, a stake is positioned 15 metres from the tree. The object is
to fell the tree as close to the stake as possible. The 27th World Championships will be held from 16-19th August in Estonia, with the cup being awarded to the overall winner of five spectacular events including felling, limbing and bucking. All of these events are designed to demonstrate both precision and speed. The last championships turned out to be a grand slam for Husqvarna. The overall winner and reigning world champion, Ilya Shvetsov from Russia was using a Husqvarna saw, with the other winners of individual events using either a Jonsered or Husqvarna saw. For 2006, the favorites look to be the reigning World Champion Ilya Shvetsov, previous winner Gottfried Schädlich, from Germany and another Russian, Vadim Imankulov. However at a recent Husqvarna pre-championship training camp, UK representative Richard Elliott beat off stiff competition from participants all over Europe to take first place. Fingers crossed he can repeat his success at the actual event in August! For more information on the event, visit the World Championship website: www.wlcestonia.com
Letter to the Editor Total Arb, Just read the letter about Loler inspections, this is why people are not carrying out this procedure correctly. Anyone with half a brain knows what dangerous climbing equipment looks like and must have less than half a brain if they continue to use it. Normal Aborists resent paying someone £s every 6 months for something they already know, what happens if your equipment is independently inspected on a Monday and on Tuesday it’s damaged? It will be replaced. It’s the daily inspection that really counts, yes unscrupulous contractors may ignore it but not sane Aborists whose lives and livelyhoods depend on there kit. After all it’s (Loler) only in place to indemnify employers and serves no useful service other than to give ageing Aborists an income. H Gibbins
