  1. Dismantled big Lime yesterday, soaked and tired when I got home. Fell asleep in front of telly at 8, woke up at 9 with the edge taken off tiredness. Showered and turned in at midnight. It took an hour of 'tree roots in the built enviroment' to get me to sleep again. Woke at 5, wide awake and mind whirring. I have been up ever since, and will hit a seroius dip about midday. Unfortunately this kind of broken sleep is quite usual for me. Infuriating.
  2. TA, I shall get myself a couple of different weights and try them out. They can indeed be bought for little over a tenner.
  3. At 45 deg I would definitely cut over then under and snap it off from above. An inbetweenical cut.
  4. I see Sorbus sells the nylon ones for £27, they weigh just 1 lb. They also seem to be available elsewhere in 1/2 lb., 1 1/2 lb, 2 lb etc. Any recommendations on what size is best? My existing rubber mallet is about 2 1/2 lb. and anything less will not bring out the boom on a big tree.
  5. Well put and point taken.
  6. My techniques were described a little roughly, in practice I am not going round whacking trees like the guy in the Rank Films gong advert. By small trees I mean young ones that I suspect through strimming damage or frost splits are developoing decay from within. In a previous life I studied geology in some depth; in rock mechanics there is a tool which I think was called a Schmitt Hammer which delivered a fixed amount of energy to the hammer blow, the recoil could be used to assess the approximatee dgree of weathering of the rock. I have been trying to get a similar approach with sounding for tree decay. The boot technique involves putting a knee on the stem and swinging the boot from the same distance back. The contact is with the flat vibram front of the boot. Sometimes the reverberation through the knee is as telling as the sound from the contact. The client understands when I explain. I should get a nylon faced mallet for bigger trees. The choice of mallet is intuitive rather than of availability. The rubber one is quite hefty and I don't use it on thin barked trees. But I am fairly confident of the indication it gives of the relative extent of decay on big old Ash, Oak and Pine for example. I am curious now to know what nylon does that rubber doesn't. As a slight aside, I recently surveyed all the trees on a golf course. The stems facinmg the tee-offs were pockmarked, the result certainly of golf ball impact. I imagine a hammer improperly used could do something similar.
  7. Great pics. That Elm stump is a busy place.
  8. Right first time! The whole tree picture was taken in Camperdown Park at the weekend, but the buds pictures were taken in the University Botanic Gardens.
  9. Anything sizeable gets the rubber mallet from me, smaller stuff gets a precautionary gentle kick at about knee level with the rubber front of the boot. I don't know how anyopne could sign off a tree without literally sounding it out. You can tell such a lot with the hammer (or boot) where the eye can't go.
  10. Maybe i wasn't clear. Over then under is a step cut for free fall. If you do it outboard it can take the saw with it but otherwise no problem. Over then under only gets the bar pinched of you cut too far, it's an additional protection against losing the piece. Most of the time over then under is straightforward and the bar comes out no bother. I think I just don't like using saws vertically, somehow it seems less controlled. And it is unusual to be in a position to be able to see through the cuts to be able to check you have got the step right. With horizontal cuts this is usually easy and at about eye level. I'll give it a try though sometime.
  11. Just had a thought, what if you had two climbers at about 100kg, one rescuing the other, total non-dynamic load 2kN. In a rescue situation, descents can be jerky at best and you may have to pull the victim off or over a branch, easily adding another 2kN. So where does that leave you with safety factors? 15kN/4kN= safety factor of 3.75, not great. I don't have a zigzag, unlikely to be getting one, but if I did I would be worried about using one for rescue.
  12. I can't see me doing many fo them... the good thing about teh step cut hand held where you finish with an horizontal undercut is that if the piece of branch to be removed wants to fall off before you wwere expecting it, the cut closes on the saw and not onto a gap; the restriction in movement prevents the step breaking which it otherwise would. You can then stop the saw and get one hand on the piece before pulling the saw out and doing the snap with both hands. If you do this vertical step cut you lose all this control. Personally I have never bemoaned not being able to waggle the step sideways instead of down or upways.
  13. I may as well put my last question to you. As you know, and I mention it largely for the benefit of onlookers, QTRA puts each of the three ingredients (Target, Harm and Probability of Failure) into ranges of probability for example 10 to 36 pedestrians an hour is taken as 1/20 target presence, which is the upper end (36 pedestrians an hour). To put it another way, it errs on the cautious side. This resultant probability is then multiplied by the other factors, which also are rounded in the 'cautious' direction . It appears to me that this has the potential to result in super-cautious conclusions from the QTRA calculator. I took some figures at the extreme lower end of each of the three factors and multiplied them together. I compared this with the product of 3 figures from the upper end of the same range. It is not difficult to find examples where the difference between them is a factor of 2,000. The difference between them in one scenario was a factor of 3,000. Since all QTRAs figures are rounded on the cautious side, what this seems to me to result in is the potential for QTRA to recommend remedial tree works for trees where the arithmetic for the actual constituent parts would not result in such a recommendation. So, for example, a tree is calculated by QTRA as presenting a 1:7,500 risk, which is considered by HSE therefore to be an unacceptable risk; let's say the remedy would be felling. However, the actual figures could when multiplied together be say 2,500 times less, equalling 7,500 x 2,500 = 1:18,750,000, putting the tree in the 'broadly acceptable' category. No work to the tree would be required. These two completely different results for the same tree appear to support the view some have that QTRA produces false precision which (with these rounding discrepancies) can lead to false accuracy. There is a question... how does the practitioner or the client or someone like myself who is a potential future customer of QTRA reconcile this all so that acceptable trees do not get felled?
  14. Another one from a recent excursion, if I said where it would give it away. The bud pictures are from the same tree, the second lot are from twig wherre buds are just starting to open.
  15. Just for, practice, anyone want to figure out what this species of tree (not a shrub) is, from a single picture of a bud starting to elongate?
  16. I woudl agree it is pointless incurring unnecessary expenditure on tree info for the whole site. However, it is not a question of whether the part of the site is 'likely to be used for development' (your words) but which parts of the 'site' (as defined in the registered application) would 'influenced or be affected by the development '.
  17. Here's how I would see it. You gave a quote to do work, it was accepted and you now have a contractual obligation to do the work and the client has a contractual obligation to pay you for it on completion. However, your quote was broken down into headings and so it should be possible by mutual agreement to stop both parties' obligations after the felling or grinding stage and for you to get paid for the appropriate part of the job that you have done. What is important is that you make it clear to the client that you are handing over responsibility for replanting to him and that it is a condition of TPO consent for which breach carries penalties. Conscience clear, professionally closed.
  18. If it's £200 net, take it. If it's £100, go climb a tree for £130 unless you want the experience and a less physical job. I've doen this sort of thing, and wandering around looking at trees it aint, it can be fast and tiring and you have to be decisive because the client can't be paying for you to pop back to the car to look things up in books too many times. If you miss a disease or pest and the client loses valuable stock due to something that could have been remedied a tthe point you missed it, you could be liable for commercial losses. So factor in your PI insurance.
  19. I am saying that knowledge of an impending Order doesn't create the offence (the existence or otherwise of the Order does that) but that prosecution is more likely to succeed if there was evidence that enquiry had been made and that the owner/contractor was aware of the possibility that an Order might exist at the time of the work even if it had not been served. Just to be super-cler though, I am convinced that in a CA you would be in the clear if you gave notice, waited 6 weeks, heard nothing back then did the work. It really is on the Council to respond within the 6 weeks, that is what the stipulation of an exact timetable in the Act is for. What makes for an interesting supplementary question is whether that notice 'life' of 2 years grants immunity from prosecution for that work on that tree even if a TPO is subsequently made and served? I believe the only answer to that question can be yes.
  20. A quick addendum. The last post might appear to conflict with my earlier posting o this thread but the earlier one related to confirmed orders adn the later to made orders. And as ever I could be wrong on both but I have given it some thought and done some research so I hope the suggestions help.
  21. It happens up here too that the Council resists replying to the agent. I generally agree with the client beforehand that if the TO contacts them after a notice has been served then all communications be redirected to me and the temptation to discuss directly with the TO be resisted. That is the only way the progrees of a notice can be controlled and miscommunications eliminated. In the situation being discussed here, it seems very much simpler in a CA than not. If the 6 weks are up there is an immunity from prosecution adn the onus (in therms of natural justice) would be on the Council to make a AND serve it within the 6 weeks. If it's not in a CA and you enquired and were told no TPO, a prosecution that was pursued for infringing a TPO that had just subsequently been made but not yet served would certainly fail. If it's not in a CA and you didn't check before carrying out tree work but a TPO had existed for a while, prosecution should succeed. If, however, the TPO was made before the work was done but served after the work there might in theory be an offence committed. The first of two possibilities is that an enquiry was made and the Council said an Order was in the process of being made. The second is that no enquiry was made. In the first possibility, it is a sprint for the line and if caught in that situation and forced to play hardball I would be asking the Council to clarify at what date or meeting a decision on the making of the Order could be expected and I would hold that as definitive. Up to that given date I would expect immunity from prosecution. In the second possibility, I would expect prosecution for infringement of a brand new order to fali (after some argument) but for infringement of a longer-standing (confirmed and recorded) Order to succeed. Cracking question though...
  22. Sorry, I didn't spot your last post. How is a moss bandage made and applied, and does it work? And how? Apologies if htis has been covered in another older post, please direct me there if it is easier.
  23. I expect the Blue Book is best practice but not law, so the presumption initially would be that you had committed an offence. The Council would not have broken the law by not having a perfect on-line register, or even any on-line register. If it had been a really new TPO and the Council hand't quite added it to an existing list, would it really be a defence to say neither you nor the client were unaware of a brand-new Order? Older TPOs could be different. But the key wording in your question is the 'in reliance upon'. If the Council's website said something like 'if there are any TPOs in the area they are listed on this website' and you were checking if there were any older Orders, then plainly you have discharged your obligation by checking the website and the Council could not prosecute successfully. On the other hand, if the website said something like 'these are TPOs in the area that we have so far added to the website' you would not be on such solid ground. Ultimately a question of reasonability, and whether you had made all reasonable checks and if you had found what claimed to be a definitive source it would not be unreasonable to rely upon it.
  24. Correction, I see from UKTC that you are still in Australia, hopefully we will hear from you in due course. For my part I only have one remaining question about QTRA which I will post when I get a little time.
  25. That's a nice bit of research, thank you. But what hope up here when the fate of deciduous trees are not even in the hands of secondary legislation or guidance but are right royally f***ed by primary legislation? Apologies for the outburst.... but maybe her majesty will refuse to give assent and the poor broadleaved recipients of gormless MSP activity will be right royally unf***ed. Would get my vote against independence instantly. I tkae the point about death ensuing from excessive cutting. But the Act says nothing about that, it just gives a right to light. Again I fear for TOs that have to walk the fine line which willl be literally impossible for some broadleaf situations.
