    Ben, I've no direct personal experience but have noted a number of London LA's using permeable/porous resin surfaces like this one.... Our Tree Pit Provides an Attractive Porous Resin Bound Surface There will be other manufacturers out there no doubt .

    Hi Alec you can clearly see the gently upward arching growth that has reiterated to its new orientation. Also, for those who may be intersted, note the young oak that was planted to replace a fallen one from the great storm of '87.

    First load of locally sourced mineral soil today, will let it rest then perhaps top up in a couple of months. Deer weren't entirely sure what we were up to .

    Here's a fine example (Church path at Felbrigg Hall in Norfolk) of an avenue lime that has fallen & been left to reiterate its canopy. It's still part of the avenue which has been suplimented with new plantings to replace fallen trees that were not root intact. Particuarly impressed by the root regeneration in the last image. Should this have been cleared up? .

    Inonotus cuticularis would fit host but the spore colour is throwing me a little here. Should be more yellow than white .
  6. David Humphries
    What's the tree? Inonotus species would be my thoughts .

    Will be covered like the first one Josh. Hopefully new roots will then grow in to the soil to eventually re plumb this side of the tree. Would be fascinating to see what's going on in the first trees soil mound with an airspade, don't think we will though .

    No long shot Kevin, we did consider that but the spend on the path & fence move was already a significant outlay. We were happy to let nature take its course here as one of the first principals of veteran tree management is in essence 'non' intervention. I'll bare your proposal in mind though as there are always situations here and at other sites where propping may be a consideration. May be worth your acquaintance reading up on the Anne Frank chestnut. That was a learning curve for those involved in the retention of a heritage tree Thanks for your input. I do know of a far more 'prestigious' tree that's in the process of assessing its current supports and the site managers are looking for something that's slightly more 'different' than the norm. I'll pm you .

    oops, damn those mince pies .

    The vistas still there Dave, it's just a little wider than it used to be .

    Some footage from a recent update given at the Linnean society (courtesy of J Heuch uktc) http://m.youtube.com/channel/UCI810ZkJIgiS9ALeeT5tq3g?desktop_uri=%2Fchannel%2FUCI810ZkJIgiS9ALeeT5tq3g .

    This is not what you're specifically looking for, but section 3.5 of the 2007 London Assembly 'chainsaw massacre' states similar to what you're referring to http://www.london.gov.uk/sites/default/files/archives/assembly-reports-environment-chainsaw-massacre.pdf .
  13. David Humphries
    That's OK Dave, I understand that you don't get it .

    a few days after having looked at the trees (on a still late autumnal day) the second tree has now gone over as we expected it would. Although it suffered a number of severed roots, much like the first subsided tree (which is still root intact & happily maintaining its canopy in its new orientation) I imagine that the second one will do likewise. .
  15. David Humphries
    Recently I had a look at the line to assess the lean on the second oak. In comparison, images 1 & 3 (which were taken in 2008) appear to show little change to the shots I took recently (2 & 4) .
  16. David Humphries
    Four years on from the start of the thread.......an update we noted one of the oaks in this line was leaning heavily and appeared to be in a slow but dynamic fall. we felt there was time, so we lifted the original path & fence that were directly under the fall direction and relayed & re-errected them on the outside to mitigate the risk of anyone being under it when it did go over. the tree went over some six months or so after the work and rested on its lower canopy with enough of its root crown still intact. It continues to grow and looks set for a few decades more. .

    Habitat objective was a significant factor but retention of a species in a general downward spiral locally also played a part in the decision. This one below (not a particularly proud moment in my tree management portfolio) was reduced/topped about 10 years ago due to an (at that time) unquantiifed fear of the unknown state of decay in the trunk of Inonotus hispidus With hindsight and the knowledge from the picus reading taken 5 years later then we would have reduced the tree a lot less in the first instance. I'm putting these up to show you how a vascularly healthy ash (Fraxinus excelsior) can respond to a heavy reduction. the resulting sprouts will (when time allows) be subordinated .

    Top man, well done Paul .
  19. David Humphries
    Got lots of them but might start teaching the eldest to climb trees as he wouldn't need petrol and would be on tap .
  20. David Humphries
    Climber is in the tree in the second shot of post 262, Guy Top section (central leader) was left at that point of initial pruning to maintain as much photosynthetic material as possible (whilst reducing the leaning weight) with a return reduction planned 3/5 years later. Trouble with woodland trees here, they get pushed further down our priority list as trees with issues in higher target zones become the focus. Some of the original management plans for these types of trees that should get second/third return works, slip. .
  21. David Humphries
    St Judes storm in October had other ideas. The principal failure occured at thepoint of the included union & not at the site of Inonotus decay. .
  22. David Humphries
    Thanks APC, appreciated Roadside ash with Inonotus hispidus in the crown stems, a heavily included union & shear cracks in the basal section of the trunk. Guys went up to have a closer look to inform the reduction spec & priority importance in our schedule. We concluded that it would be maintained as a topped tree at 50% its original height for its habitat value. Work to be carried out this winter. .
  23. David Humphries
    possibly Podoscypha multizonata .
  24. David Humphries
    'twas a fiery start to the day .

    Unbelievable Ian Fine looking work there Adam, liking that .
