    Definitely the previous years Psuedoinonotus dryadeus brackets. .

    I haven't come across F. velutipes on Liriodendron before Jules, and there appears to be no UK records for it. British Fungi - record details I suspect there would be a pretty common association of the two over in the States. May also be worth considering the other Flammulina species with this one as well, as they are pretty similar. Flammulina populicola - rare in the UK Flammulina elastica - also fairly rare in the UK .

    Team leader Mr Nicoll tickling this wee pollard in to submission before tickle after tickle and a bit of during tickle .

    Bulging beech from Burnham Possibly posted it before, but too cool not to share again. .

    We've scored the bark as a data measuring point on that old pine and have also nailed a flat board with scored measuring points on an oak. .

    Paul Barton shared this little useful tip for measuring leans a few years ago we continue to use it to good effect on a couple of leaning trees were monitoring. http://arbtalk.co.uk/forum/general-chat/40740-guying-leaning-trees-4.html?nojs=1#links

    Although its over 7 years old, it would be an interesting exercise to canvas whether the Joint Mitigation Protocol is still a being used as a method of subsidence claims management. Where trees have been implicated as being the cause of building movement, the JMP sought to establish best practice in the processing and investigation of tree root induced building damage, benchmarking time scales for responses and standards of evidence. http://www.ltoa.org.uk/resources/joint-mitigation-protocol Its had approximately 6000 downloads during its lifetime and was signed up to by London & Southeast Borough Councils, Arb & Environmental Consultancy's, Insurance Companies and Loss Adjusters. Joint Mitigation Protocol. I wonder how many actual trees have been retained due to the protocol. .

    Not that I'm aware of. There are individual records of 'some' of the largest, oldest and heaviest specimens of perennial and annual fungal fruit bodies but not a definitive list. Under Schedule 8 the Wildlife & Countryside Act 1981 there are currently only 4 species of fungi in the UK protected by law. Oak polypore, bearded tooth, sandy stilt puff ball and the Royal bolete. .

    Interested in seeing the other fungal species, if you do get the chance. Psuedoinonotus dryadeus is normally thought of as a heartwood white rot decayer leading to pronounced buttress formation, which can result in a wider more stable base. Though it has been noted in sapwood regions in advanced colonisations, so 'further investigation' using something like a decay detection drill would paint a clearer picture as to strength of the trees 'feet' Why do you say/think the aesthetics of a phased retrenchment/reduction (to help with the stability of the tree) would not be acceptable to the site? .

    5 years on from the first post in this thread and we've just been back to undertake the next phased height reduction of the pollards over shadowing the ballerina. The ballerina is still flushing buds well with little decay of its remains basal strip but there is now significant squirrel damage to the bark on its upper branches. .
  11. David Humphries
    Looks like the fruiting is all around the trunk. Was the canopy in decline? What did you prescribe? .
  12. David Humphries
    Yep, insect frass Kev, no idea what had been in them. .
  13. David Humphries
    Nice example of aerial rooting (although mostly aborted/withered) on this fine old hollow beech pollard at Burnham from earlier today. .
  14. David Humphries
    Unknown species and number of endophytic fungi colonising this lump of beech taken from 15m height. .
  15. David Humphries
    As Mr scotspine1 has suggested, could you post a whole tree picture? .
  16. David Humphries
    It's gone, there is no viable vascular tissue left in the parts of the tree that you are showing us. The fungus is saprophytic (possibly Bjerkandera adusta, the smokey bracket) and feeding on the dead/dysfunctional wood. Has there been any ground work carried out around the roots of the tree? .
  17. David Humphries
    Thought we'd lost you full time to the Facebook groups Guy Height reduction of the remaining three poplars to manage the increased exposure and replacing the void with another fastigiate tree (pop or oak perhaps) .
  18. David Humphries
    Coming out Al or a candidate for reduction/bracing? .
  19. David Humphries
    Sad news indeed, thoughts with his family and friends. A rare but sobering reality of the risks that exist to us all .
  20. David Humphries
    Yes Jake, been drilled a number of times over the last 5 years or so. As you probably know, standing Habitat sticks are our usual default position but as we learn more and more about specific decay types and their interaction with specific tree species we have learnt that Perinniporia and ash does not 'stand' the test of too long a time. [ame] [/ame] Some of the upper wood volumes decayed by Inonotus hispidus have been resurrected in an adjacent tree to continue the habitat cycle. [ame] [/ame] .
  21. David Humphries
    Ash with the dual decay of a long time colonisation with Perenniporia fraxinea and more recent Ganoderma australe colonisation. Both have led to white rot decay which has consumed the lignin. Psuedosclerotial plates separating the various colonies of the two fungal species and ants making the most of the decay by mining the altered wood volumes to create a maze of ant habitat. .

    Brrpp

    Ash with Inonotus hispidus, Perenipporia fraxinea & Ganoderma australe White rot decay habitat that has been resurrected twice once its parent tree gave up the will to keep standing........ [ame] [/ame] .
  24. David Humphries
    Liberal sprinkling of midichlorians just to nudge it back on its path to land gracefully where we wanted it .
  25. David Humphries
    Haven't put anything up for a while so here's a quick mash up of images & videos of a significantly decayed ash we've been managing down to the ground over the last 10 years or so.... [ame] [/ame] .
