  1. What a miserable miserable pessimistic attitude...
  2. As significantly, I have found their leaf margins to be much more orderly, Zelkova is non-wispy and Ulmus is so unmistakably Ulmus as to be definitely not anything else.
  3. I'm almost certain this is a Carpinus betulus 'Pyramidalis'. Hornbeam, at least the Pyramidalis, can have an asymmetric leaf by about one vein on the inward side of the leaf,,but this tends to disappear in the leaves towards the apex of every twig. Everything else in the pictures is saying C.b., even the wound callus. I have pruned a few of these and the density of the crown and the uniformity of the sub-fastigiate branch structure is so rare as to be unforgettable. On the other side, I can't reasonably fit this into any Ulmus or Zelkova description.
  4. Good avice there about learning the terminology. Without it the guide books are nowhere near as useful. I virtually lived in the Botanics when I was studying for the tree/shrub ident part of the AA Tech. There's at least one of almost everything there that you'll come across in work. Another tip, don't go too much by the leaves. Half the year you won't have these to go by. You may come to find buds just as useful as leaves. And make up silly mnemonics. So if yoyu are faced with something in winter and you don't know if it's a Whitebem or a Swedish Whitebeam, you can look at the buds and remember - "Green, whitebeem Reddish, Sweddish" Sort of rhymes.... I have dozens of these in my head.
  5. Looks, as others have said, like Himalayan Balsam. Unless you find it delightful and want lots and lots more of it, and think that your county will welcome it in abundance, kill it now mercilessly.
  6. That is gorgeous! Fasciation plus post-fasciation tropisms.
  7. Sooooo nice not to hear somene saying 'fell the b***ard' or 'good firewood' that'.
  8. Stonking big P. squamosus on fallen section of sycamore, central scotland.
  9. Nothing unusual here, L. sulphureus on Oak in the Borders, the dieback could be as much to do with ploughing of the field behind as anything else.
  10. And going by the dust pattern there will be a few more up the stem out of shot. Or somebody has sneezed in a tin of cocoa powder nearby.
  11. That's my experience too, it's not even a shelf-filler as several have seen it online throught their corporate BS membership and not bothered to get a hard copy. I'm wondering if I still have a point here, I suppose it is that the microguide can have its moments because officially it is backed by the BS, and it can save time, expense and paperwork in a lot of urban tree situations.
  12. Now that's touting for business. Anyways, all this shows that the industry hardly knows where it stands (occasionally stamps?) on bats and that the new British Standard and microguide have laregly failed to reach the consciousness of the very industry that should be taking it up. As Jon Heuch says "As for best practice, you should be in a position to check for potential bat roosts without the assistance of external parties........it's just too common a position to be in." But it's having a defense if something goes wrong, or reassuring customers and clients that they are covered, that matters. The OP is probably well able to check that there are no bats just now, but that's not quite what the law says, roosts are protected even when not in use. What the heck, he hasn't even said he wants a survey done. I'd charge £25, but for only a few times that price he could get trained up himself and do as many as he wants and decided either to charge for them or offer it as a free bonus service.
  13. I don't think that the 48 hours is to do with risk, it's to do wth making sure bats don't take up residence after the survey. Prevention of danger is a valid exemption from felling license requirement. Removal of risk is a valid exemption from normal bat precautions but only if the risk can't be reduced by other means such as closing off the area beneath the tree until proper bat precautions are taken. Even then measures are required to minimise risk to bats, such as lowering sections.
  14. You're right it doesn't. I have also done the endoscope training for bat inspection course. I think if you only do the bat awareness training it would tell you clearly not to use an endoscope without the additional training.
  15. That's not so, it allows you in some cases to rule out bat roosts without calling an ecologist. That, indeed, was the whole point of the scoping survey being introduced as an option.
  16. I've domne this once, but you need to be absolutely sure it's an empty roost and not the only one available in the area. Obstructing a roost is tantamount to destroying it, which is indefensible. So I am told, but it seems consistent with the legislation.
  17. The new BS8596 allows for a greatly simplified survey (non-specialist scoping survey) to be done to establish if there is low or negiligible risk of disturbing bat roosts. It's a combination of age, condition, species and position of trees and proximity to bat foraging areas. If this is all-clear, practices vary but the ecologists I work with generally say an all-clear buys you about 2 weeks to get in and remove the trees. This is not in the British Standard but it would seem to be a reasonably defensible position. I'm not touting for business but I have undergone the bat awareness training required by the British standard and if you are stuck for an all-clear I will coincidentally be in the Borders on Wednesday to Saturday on tree survey and could possibly do you a scoping survey. It's a written report, barely a page, minimal charge if it's an all-clear, slightly higher charge if a climb (possiblly with endoscope) is required. And a verbal OK on the day if appropriate. And to answer the question, a time limit is normal but 2 days is I believe unnecessarily stringent. PM if you want or carry on discussing here.
  18. I'm convinced (after years of pondering and observing this very question) that it makes (or it can depending on species and age and situation) quite a substantial difference.
  19. As for removing it, that's rarely necessary. But reducing its height and spread proportionately to reduce wind loads so that it is unlikely to fail catastrophically but leaving enough crown to allow it to continue for a decade or two might be a compromise. Who's going to be in the garden in a hurricalne if it snaps? It's all about striking a balance between likelihood of failure, consequences of failure, wanting to keep it for a while, the cost of doing so and taking objective advice. The guy who pointed out the problem was right to do so, but none of us have seen the whole context (or even the whole tree!) so he might be right or he might be over-reacting or he might be preying on fears. we don't know. Butr free advice usually comes at a cost. So it's worth pausing and weighing up the pros and cons.
  20. I am in no doubt that you are right. it looks to me like well aerated K. deusta.
  21. Pigeons. https://www.rhs.org.uk/advice/profile?PID=207
  22. And the rest
  23. I just came across these pics I took last year of how to tie a Distel witha fixed loop of rope. It's a slight improvement on the Schwabian I use, but only because it is easier to shunt along the rope with a pulley. May be of interest to someone who wants to try the Distel but hasn't got an eye-to-eye.
  24. You cna have this one if you want.
  25. It's an Ironwood all right. When you see one in autumn you will appreciate that they can have yellow, red and orange all on the same leaf at the same time.
