      Latest Entry

      The other day someone asked me what the Latin was for a Judas tree. I said “well that’s a silliquastrum”

    2. Man has always had a direct link to the landscape, though that link, whilst it is always there, may not be in the form that it once was. Keeping with the wood pasture theme, which I am really enjoying learning about through books and journal articles, I thought we’d look at how the manner in which we approach the ecosystem has changed over the centuries (quite briefly). Of course, what is written below doesn’t stop just at wood pasture – it has cross-over to other ecosystems, where the reasons for interaction with the landscape have altered through space and, more pertinently, time.

      Historically, wood pastures were managed for economic purposes. The grazing of animals on grasslands containing trees (and the feeding of the livestock with cuttings from pollarded trees, and a tree’s fruit crop), such as cattle and pigs, was for the direct benefit of communities, who relied upon the produce of the livestock (milk, meat, and so on) in order to make a living, and to generally therefore survive. Of course, the wood pastures needed to be conserved, so that they did not disappear, due to over-grazing. In this sense, they were actively conserved (by replanting dying and dead trees, and limiting grazing intensity), though largely because, without actively conserving them, the livelihood of many tens of thousands of people would be challenged. A by-product of this conservation of wood pastures, for the benefits created from grazing livestock, was that the sites were very rich in biodiversity – birds, fungi, insects, and plants, for example. The complex mosaic of niches within the wood pasture, ranging from open and disturbed soils through to the (perhaps sizeable) groves surrounded by the mantle and fringe vegetation, meant that a large number of organisms could viably frequent the site. However, for all of the biodiversity present as a result of the careful management and conservation of wood pastures throughout history, biodiversity was not the reason for management – until recently.

      The shift, in Europe, probably begun when wood pasture became disliked (for hope of a better word), during the 19th-20th century (varies depending upon the country). Foresters wanted to maximise output from the trees (coppice – sometimes with standards), and farmers wanted to maximise agricultural output. Therefore, the two practices, initially married, were divorced from one another (somtimes farmers were forced to stop grazing their livestock in wood pasture!). Wood pastures were thus either cleared of trees entirely, or alowed to regenerate into forest. With this came a decline in the richness of biodiversity and, eventually, this loss of biodiversity caused a rather evident of panic amongst conservationists. Ironically, therefore, the rationale behind creating and maintaining wood pasture became largely ecologically-driven, in place of economically-driven (though, particularly in Spain and Romania, wood pastures remain, are these are generally economically viable). Regardless of reason however, the status of wood pastures essentially went full-circle.

      Of course, this new found love for wood pastures does not necessarily mean that they can ever exist in the manner in which they did before. First and foremost, wood pastures are extensively grazed, and thus, for operations to be self-supporting financially, they must cover large expanses of land (unless the wood pasture is maintained for subsistence purposes, or grants are provided as a means of financial support). As farmers in Europe are generally in ‘the game’ for profit (they must make a living), managing livestock in wood pastures is probably not going to be all too popular, as it’d probably signal a marked drop in profits and / or a marked increase in labour input (at least, initially). Scope does exist to harvest edible mycorrhizal mushrooms from the wood pasture, such as truffles, though this is a specialised pursuit that is far from the current farming status quo of Europe.

      Furthermore, European culture has changed. Gone are the days of communities being self-sufficient, and instead many Europeans now work a job (that they may even hate) and buy their food from the supermarket (or even order it online). Therefore, is there even the desire to re-introduce wood pastures, for anything other than ecological reasons, or to supply the market with a niche animal product (such as Iberian ham from the black Iberian pig, in the holm oak dehesas of Spain). With this change in culture there has also been a change in learning priorities, and unfortunately many today seem to be fixated with knowing pointless facts about sports teams and celebrities. Functional and practical knowledge is largely gone. As a consequence, the management of wood pastures will be left to an expert few, where knowledge has either been gained academically, or via being passed-down through the generations (usually limited to rural areas where grazing still takes place). However, as more people now live in cities than in rural areas, and this trend will likely continue as rural areas are swallowed up by urban sprawl, or people move into cities for economic reasons, this tradition of passing practical knowledge on and keeping up the family tradition of extensive livestock grazing within wood pasture may very well become ever more the stuff of legend.

      Society is simply in a different place than it once was. For this reason, the conservation of wood pasture is to be far from mainstream. People are certainly aware of nature (of which wood pastures feature), though more and more awareness comes from watching on the television and less from direct experience, and with this comes a discord. There is less emotional and cultural attachment to nature, and as a result, less of an impetus to associate with nature. Why help with the recreation of wood pasture when you can watch about its conservation on television, utter some lamentations, and then switch the channel and soon relegate it to a mere memory? That’s even assuming people watch such programs, in large numbers, in the first place.

      This probably turned out far more dystopian than I ever intended for it to come out as, though hopefully this illustrates how social changes have led to landscape management changes, with specific focus upon wood pastures in Europe. This is obviously applicable to other landscape types as well, of course. The principle generally carries across.

      Source (of inspiration): Hartel, T. & Plieninger, T. (2014) The social and ecological dimensions of wood-pastures. In Hartel, T. & Plieninger, T. (eds.) European wood-pastures in transition: A social-ecological approach. UK: Earthscan.

    3. We have been splitting logs lately, the timber has been lying in the yard for a couple of years and now we want to get it converted into logs to finish seasoning indoors so we have been busy with the firewood processor. Looking at the pile of logs and thinking about selling it all next winter has led me to consider the best way to market and sell our produce.  Since Trading Standards and the Weights and Measures Act 1985 have little to say regarding firewood we are a bit in the dark when it comes to quantities, packaging and pricing. With most goods the law is quite clear and very strict with serious penalties for suppliers who sell goods in quantities or measures outside those prescribed in the Act. Firewood however is a bit of a mystery, I suspect that it falls under the category of solid fuel, but its hard to confirm if thats the case. However it is viewed officially it would appear that the market is wholly unregulated.

       

      Logs are sold in a variety of ways, here are a few of the most common:

       

      By weight; usually by the “ton” however this is almost never confirmed by any kind of weigh bridge ticket something which  is likely to be illegal as far as the weights and measures act goes as one thing they are strict on is selling by weight. There is however a fundamental problem for the consumer with buying timber by the ton, this is simply that the wetter the wood the more it weighs. So there is an obvious incentive for the supplier to sell unseasoned wet wood as this will significantly ‘up’ his margin, if he bothers to weigh it at all that is!  Supermarkets have been dicing with the same issue for years when it comes to meat, hanging the meat performs the same function as seasoning logs, it dries out a little and whilst the flavour may improve, and possibly the price per kilo, the lost moisture is lost profit since they bought the meat by weight in the first place. They have got around this problem by injecting the meat with “stuff” to bulk up its weight, and apparently this is ok with trading standards! This has gone on for years of course, in times gone by bakers used to be infamous for adulterating their flour with fillers such as bone meal, chalk, sawdust and even gypsum! Thankfully at the end of the 19th century laws were brought in to standardise what could be called flour, maybe its time they took a look at bacon! (all that white stuff that comes out as it fries is the supermarkets added filler).

       

      So back to logs, selling by weight simply encourages the supplier to sell wet wood, and wet wood is not good for burning, not only does it produce little heat but because it burns at a lower temperature the combustion is incomplete, so gaseous tar and soot condense in your flue potentially leading to chimney fires. It would perhaps be ok to buy logs by weight at a known moisture content as happens in the wood chip for biomass industry, but that rarely happens.

       

      By far the best way to buy firewood is by volume, this way you get what you pay for, they may still be wet, but 100 logs are still 100 logs wet or dry, so now the incentive is with the supplier to sell a quality product, assuming he wants to keep your business that is. So the next problem to arise is quantifying that volume, a cubic meter is a relatively common unit and should be the ideal but thats not always the case, which leads us to what is perhaps the most common way of selling logs…..

       

      The load. So what is a load of logs? Well, anything you want it to be really, and this is where the industry really needs some guidance from the government. The load could be a bulk bag, but these vary in size from 2 cubic meters down to less than 0.5, or it could be a vehicle of some sort, trailer, pickup, 4×4 or even a car boot. From the consumers perspective how are they to compare one ‘load’ with another, does the back of one suppliers transit van compare favourably with another’s trailer? Who knows?  The upshot is the poor consumer is left in the dark. With weights and measures regulations so strict on other industries, including coal and smokeless fuel, why is it that logs are still in the dark ages when it comes to consumer protection?

       

      The answer may lie in the fact that during the industrial revolution we abandoned wood as a fuel, only to re-discover it in the last 10 years or so, and when the laws on weights and measures were made firewood just wasn’t on the radar. But these days it is most definitely back as a serious contender in the fuel market, sales of wood burning stoves have soared thanks to the carbon neutral credentials of  burning wood over fossil fuels. (don’t get me started on the carbon credentials of imported eastern european logs though!)

       

      Its time for HM Government to wake up to the burgeoning market in firewood and apply a little common sense to the way in which our logs are sold. We could do with a standardised moisture content for firewood, so that customers can expect to be able to get a certain calorific value from their wood, at least if its advertised as ‘ready to burn’ anyway. Then theres the weight / volume issue, logs really should be sold by volume, and all prices should be advertised by the cubic meter, irrespective of the size of vessel used to deliver them. This way the consumer can confidently compare prices from one supplier to the next. We have found that selling by the cubic meter we loose out to other suppliers selling by the bulk bag, our £60 per m3 has less appeal than a £50 bulk bag even though that bag may only contain 0.6 cube, making it considerably dearer, what do we do, sell unseasoned wood in order to cut our prices further, or try and skimp on the amount we sell?. Sadly the lack of regulation is currently driving quality down as firewood producers engage in a race to the bottom to stay in the game.

       

      So if you agree with the views expressed above please share this article on Facebook with your local trading standards office, yes they all appear to have FB accounts! You could also share it with your MP. You never know we may end up with a fairer firewood market in the not to distant future.

       

      For some further reading here’s a helpful PDF from the Forestry Commission.

    4. Sunday 28th October marks the official end of British Summertime, although we are already experiencing a drop in temperatures compared to July and August. The Forestry Commission recently announced that the result of dry soils left by the long, hot summer coupled with late summer rain, we are in an early autumn period.

       

      This year’s APF event saw the Forestry Commission celebrating 100 years of the Forestry Act, providing advice and support to the sector and commenting on latest activity. With forestry workers 6 times more likely to be killed at work than a construction worker, knowledge sharing and education remains a critical part of the work required for future development. With the HSE citing growing concerns on the level of competence and high expectations of newly trained/qualified operators, this has never been more important.  

       

      In this industry, with the nature of the job including working at height and the risk of falling objects, working with chainsaws and other equipment, careless oversights could quickly turn into serious incidents. The role of technology has increased, as has the need for tree maintenance. Workers can feel instantly reassured by this, possibly too reassured. A reliance on technology could result in arborists and forestry workers becoming less alert to potential issues. 

       

      We all know that PPE serves as an essential part of helping to protect those in the forestry industry at work, however, a safety conscious attitude and frame of mind at work is equally as important. It is not enough for workers to rely on PPE, believing that they are 100% safe when they have their PPE is prepped and ready to go. Health and safety needs to be a forefront of the entire workforce’s mind, helping to reduce the amount of carelessness and distraction at work. Put simply, even with PPE and advanced technology employers and site operation managers need to reiterate to workers that this does not render them unexposed to potential incidents. Accidents can still happen and it is critical that workers have a good understanding of this.

       

      1,2,3 – PPE 

      The purchase of PPE is only the first step in the equipment’s journey.  It must be regularly maintained and replaced, whilst continually ensuring it is most suitable for the job being completed at the time.  

       

      Successful management of health and safety and the role of PPE requires co-ordination of activities and communication of information, and must start from the top down. Leading by example will not only resonate and encourage workers on the ground to follow suit, it will go a long way in fundamentally improving health and safety performance across the industry for both newly trained and more casual users.  

       

      PPE is not a guarantee of safety, and the role of the individual remains crucial.  Stay aware and alert. Appreciate the equipment with the knowledge that you also play a significant role in ensuring you do not get hurt at work.

    • Stolen Wood Chipper Recovered
      We all know how theft is rife, particularly it seems within the tree care industry. Barely a day goes by when there isn't machinery reported stolen on social media, Arbtalk, or the Arbsafe database of stolen tree surgery equipment.
       
      The effect of these crimes can be massively damaging, particularly for smaller outfits. Not only does the victim suffer the loss of their tools, but more often than not there is significant damage done to their properties in the process. The issue is only compounded by the fact that many yards are in rural areas where police response times are likely to be far longer than elsewhere, if indeed there is a response at all.
       
      One Cheshire based tree care company recently had their Timberwolf wood chipper stolen along with many of their tools. Fortunately for the business owner, they had invested in a sure-track wood chipper tracker, which, with its 91% recovery rate within 9 hours, proved to be a hugely worthwhile investment.
       
      The unit was put into alarm mode within a couple hours of going missing, and the sure-track team knew they had to act fast, dispatching one of their experience finders immediately to a location near Bolton. Using RF scanning equipment, they bag a thorough investigation of the area and picked up the signal from the stolen wood chipper within a matter of minutes. The police were called and promptly arrived to assist with a successful recovery.
       
      Not only did Sure-Track recover the chipper, but also the majority of the tools were also found in the same location, leaving one very happy customer.
       
      If you are a tree surgeon or run a forestry business then you are right to be concerned about machinery theft. We believe the tracker solution we offer right here at Arbtalk is one of the best on the market, and as has already been proved, works! Check out the sure-track wireless theft recovery tracker for more information.

    • Two Rope Working Consultation
      So following on from the other thread I’m starting this as a more serious discussion as to where we go from here.
       
      Please keep any responses sensible and constructive, use the other thread for any banter / moaning. 
       
      https://arbtalk.co.uk/forums/topic/116973-background-to-the-hse-decision-on-two-rope-working/#comments 
       
      This is being read by the HSE so if we want to persuade them that we are a serious professional bunch whose concerns ought to be heard then we need to behave accordingly.
       
      For staff of the AA or HSE  I have tried to summarise a lot in one paragraph, if I have got anything factually wrong please post corrections.
       
      So to very roughly summarise how we got to this point: the EU passed a directive in 2004 which the U.K. adopted into our own HSE law, this stated ‘roughly’ that for rope access 2 attachments to separate anchors were required. At this point our industry through the AA and possibly others pushed back against this citing many of the issues that have been raised on the other thread. This push back was successful since at that time almost all tree work was being carried out using DDRT (doubled rope techniques) Helpfully DDRT is classified as work positioning by the HSE and not as rope access, ( basically if the rope is static and the climber moves up and down the rope it’s rope access and if the rope moves with the climber it’s work positioning, don’t ask why!) So we all carried on as normal using work positioning techniques, usually tying in twice when we were cutting and once the rest of the time.  More recently however SRT has been adopted in tree work, this shares much more with rope access and is classified as such by the HSE (fixed rope remember).  So at this point it became increasingly hard for the AA to argue that tree work was a special case since the techniques used appeared identical to the rope access industry which had been happily using 2 lines for a long time.

    • Paul, @AA Teccie (Paul)
       
      Can this article be translated into a couple of sentences for simple folk rather than pages of script which left me no clearer on what / when a change might be imposed?  
       
      Is it saying that HSE require climbing arbs to use 2 separate ropes rather than the 2 ends of the same rope (for those that still dwell in the 19th century?) 
       
      If so, when is this likely to be implemented?  Are we non-compliant now?  Is the training non-compliant?  
       
      I have to admit, after reading it, I wasn't really any clearer on whether a change is imminent now, in the near future or maybe not at all.

    • No more imports of Oak trees from Netherlands, Belgium or Germany
      ! ! No more Quercus imports from the Netherlands, Belgium or Germany…..press release Friday 12th July 2019 from DEFRA.!!
       
      Tighter restrictions on oak tree imports to come into force.
       
       
      Strengthened measures on the import of most species of oak into England are to be introduced to protect native trees from the threat of the tree disease Oak Processionary Moth (OPM).
       
       
      The bolstered measures will only permit imports of certain oak trees, including:-
       
       
      · Those from OPM free countries.
      · Those from designated pest free areas including Protected Zones (PZ) - an area of the European Union declared free of OPM.
      · Those that have been grown under complete physical protection for their lifetime.
       
       
      This Statutory Instrument (SI) – which is due to be introduced in Parliament shortly– builds on measures introduced in August 2018 and applies to all oak trees, except cork oak, over a certain size. 
       
       
      The restrictions will cover both imports from overseas and the movement of trees from areas of the country where OPM is already present – in London and surrounding counties.
       
      At the Barcham Trees nursery in Cambridgeshire, UK, we have been enforcing a strict Biosecurity Policy for a number of years.  
       
      Our trees are supplied free of OPM. Visit www.barchampro.co.uk
