    A few snippets of info from the findings, as reported by Kenton Rogers from Treeconomics at the Big Barn Conference at Barchams a couple of weeks ago. London has 21% canopy cover which compares well against other major European cities. The city is roughly broken down in to; 30% residential 20% park 8% transport 7% commercial 5% institution 1% cemetary 1% wetland 1% vacant The predominant tree species found was (surprisingly I thought) Betula followed by; Malus Tilia Acer Platanus Quercus Crataegus 45% others The above figures make London the most diverse urban forest in th UK Not an awful lot to chew on at this point, as this was really just a taster/snap shot. We're still waiting on the release of the full report. I'll update more when I can. .

    Impressive image Mario .

    Cheers for the comments Joe, appreciated. Agent Arb was last seen climbing the stairway to heaven........ If he doesn't bring me back a golden harp he'll be plucking OPM caterpillars in his trolleys .

    Too decayed to burn Mark, plus the bugs would crawl out and infest the Bentley on the way back to the country estate no matter how hard the staff tried to sanitise it .

    Nice one Joe, looked fun .
  6. David Humphries
    Yeah it was a good one, cheers mate. Team enjoyed the challenge. .

    We've reduced about 3m off the top. Not wanting to lose the top section (which would have disintegrated on impact) we rigged it off a high line with the Hobbs. Too decayed to climb, (it wobbled like a very wobbly thing) Ali worked off a separate high line further above the rigging line. The detached section will be resurrected on an adjacent tree. .

    Beech that died around 10 years ago which was subsequently reduced & coronetted in 2007. Its part of an ongoing monolith survey thats looking to record the insect fauna of this specific habitat type at the site. Various decay species (Ganoderma applanatum, Fomes fomentarious & Daldinia concentrica) have slowly devoured significant portions of its volume to the extent that we couldn't keep it standing at the same height anymore due to the target of a woodland desire path & also not wanting to lose the standing dead wood & its associated biodiversity. .

    So a year on down the road eggs have hatched and we now have the caterpillars at one of our satellite sites. .

    Howdee Phil, good to see you back on. Nice images, although a tad over its best for harvesting were you tempted to slice it up for the kitchen? Always best to take the higher ones as the ones that fruit lower down tend to have a unique canine scent .

    Look like a Coprinus species, if so then likely to be acting saproxylically on dysfunctional tissue. .

    I'd agree with Kevin that it 'looks likely' though a word of caution, we have found that what we perceived as being G. applanatum brackets with the usual associated morphological features turned out to be G. australe when we looked at the microscopic features (spores etc...) Ofcourse there's a significant decay difference between the two species across different tree types, so caution is the way to go in my experience. .

    The Woodland Trust | Ancient Tree Hunt | Tree details Were you fairly rigid with the reduction/retrenchment spec Sam, or did you have the freedom to reduce to where you felt was required whilst up you were up there ? .
  14. David Humphries
    Here's another shot of it from the Ancient Tree register. Does the tree still have the prop on the lower branch that up you can just see in the winter image above ? Fine tree .
  15. David Humphries
    Thanks for the background Sam, is this the tree? .
  16. David Humphries
    Nice work Sam, thanks for sharing. Any still shots from before and after? Was this a planned first phase of a series of retrenchment prunes? .
  17. David Humphries
    Yep, think it has all the hall marks of G. applanatum .
  18. David Humphries
    No known issues as far as I know, delete it and try reinstalling it on wifi. .
  19. David Humphries
    I'll be there, looking forward to it. .
  20. David Humphries
    Good heads up, particularly like the look of the Johnston book. Cheers .

    Fine bit of editing and looked a well managed job Rich. Liked the drone aspect Did you guys get much interaction from the locals in the flats either way? .
  22. David Humphries
    Amanita are mycorrhizal fungi which are to be found on the floor growing associated with roots of trees. I would think this is a Pholiota species, P. aurivella may be one to consider, also P. squarrosa. Have a look in the fungi directory above....... .

    I skipped through it Adam, 29 is just way too long. I appreciate its more work but perhaps create a bridged version as a summary/taster ? Fine work though .
  24. David Humphries
    Nice piece Patrick .
  25. David Humphries
    Also looking at the Woodland Trusts Tree of the Year campaign .
