    No need, the information is already out there. It is explained by the 'tree statics model'.

    It appears to be consistent with the fungus Biscogniauxia nummularia. It colonises dead/dysfunctional parts of beech trees. I can see that there are a lot a dead patches of bark in the pictures and the crown looks quite thin. I suspect something has occurred that has caused the trees to go into decline such as root damage, water logging, sudden exposure to light. The B.nummularia is likely to be an effect of the poor physiological condition rather than the cause. However in southern Italy it is believed to be a pathogen, but I'm dubious about it.

    It is strange that it mostly affects slim, fit men. As far as I know the experts don't know why that is. In glad yours was mild. It is scary when it happens though isn't it? If it happens again don't hesitate to get to hospital. Luckily I was in the back of an ambulance when mine was at its worse. I dread to think what it would have been like without oxygen therapy.

    Just out of interest - have you had a virus/cold that gave you a cough recently or had pleurisy?
  5. Paul Melarange
    I feel for you my friend. It's a fairly unpleasant experience. I had a spontaneous pneumothorax about 13 years ago. Fortunately I was rushed to hospital and put on oxygen very quickly. I don't want to scare you so won't say anymore, but feel free to give me a bell if you want to chat about it. Hope you make a speedy recovery.

    It's impossible to say without actually looking at it. However, it might be possible to regain a reasonable level of stability by crown reduction. Pollarding it is likely to result in so much dysfunction that it will die within a few years. Assessing the risk it poses (i.e by considering the target/s, size of the part and the likelihood of it failing) should form the basis of your management decision in this case.

    Good point Stubby, I missed that 😳 So I guess the confusion (apart from my own) is whether the spec was to cut back to the most recent pollard/topping points on a tree that has been pollarded/topped at a number of different heights or whether to cut back to original pollard point (bolling)?
  8. Paul Melarange
    It seems that either you or the person writing the specs (or maybe both) may not quite understand the term 're-pollard'. To 're-pollard' would usually mean cutting all the regrowth back to the previous pollard point (sometimes referred to as a knuckle). It sounds, from what you have written in your posts, that you 'topped' (i.e. made internodal cuts at arbitrary points along the branches) to provide clearance from the satellite dish, is that right?

    I think Chris is absolutely right. I have seen this on numerous occasions when walking through areas of felled plantation. The stumps on the edge (near standing trees) exhibit wound wood which I'm sure results from a combination of stored energy in the cut stump and the sharing of resources through root grafts. It is worth noting that what we can see in the photo above is 'wound wood' rather than 'callous'. It would have started as callous but has become wound wood.

    Could be a girdling root or root damage that has resulted in dysfunction on that side of the stem. It could also have been caused by an adjacent bonfire, that wasn't close enough to scorch the bark, but the radiant heat enough to damage the cambium on that side. Just some thoughts. I hope these are helpful.
  12. Paul Melarange
    What is the reason for the reduction?
  13. Paul Melarange
    This has got to be a wind up surely?

    John I have been using digital systems for recording tree data for about 9 years now. I certainly wouldn't go back to pen and paper. The key is to get the right database - one that you can customise to suit your requirements. The database should allow you to record the information that you want. I use some specialist tree management software that is not really commercially available, so there is no point in recommending that to you. However, I have used the Pear technology software in the past and it seems pretty good. It's certainly customisable. It is important to look at the various ways the data can be exported. Some will produce PDFs - but again you need to be able to customise these for your own requirements. Most will produce an excel or csv spreadsheet which might be enough for what you want. I've just had a quick look at the 'tree smart arb' website. It looks like the data fields and the reporting could be quite restrictive, but that is just a hunch. I hope this is useful.

    When it comes to the risk that these features pose Kevin is absolutely right. However, I'm guessing the question you have been set relates to the likelihood of failure rather than risk. The answer you are looking for is in 'Principles of Tree Hazard Assessment and Management' (Lonsdale, 1999). You could also look at Duncan Slater's recent work to provide a more detailed and up to date answer. What course are you on?

    Hi Gary, I hope you're doing well my friend? I have been using Promap for years now. It seems to be ideal for my requirements. I purchase the map/plan as a dxf and import it into the tree management software that I use and away I go. For the average domestic property you are looking at a cost of between £14 and £16 plus VAT. www2.promap.co.uk

    The bark of S. torminalis is similar to pear. In my opinion the bark in the pictures looks more like Crataegus. So I'm sticking with C. Mollis 😛
  18. Paul Melarange
    At least it's been narrowed down to the subfamily Amygdaloideae. You've got to be happy with that! 😃
  19. Paul Melarange
    The base of some of the leaves is quite elongated, which is confusing. God knows 😏
  20. Paul Melarange
    I think it's probably a Scarlet thorn (Crataegus mollis), but it could just as easily be Matt's suggestion of Italian crab.
  21. Paul Melarange
    Haha, Chris beat me to it 😀
  22. Paul Melarange
    I don't think we can make any recommendations based on the information that has been provided. What is the vitality like? Is there any die-back in the crown? How tall is the tree? Has there been any excavation on the that side of the tree?
  23. Paul Melarange
    The rubber tubes on mine lasted about 3 and a half years before they looked like they were too perished to chance using. That was infrequent use - maybe once a month. It was kept in a garage most of the time.
  24. Paul Melarange
    I wonder whether the company providing the arboricultural consultancy are paid per tree? It would explain why they have included so many trees that appear to be insignificant.
  25. Paul Melarange
    When I looked into the cost of the Picus 3 towards the end of last year it was approximately £18,000 plus VAT
