    They look like Fomes fomentarius, Coprinus comatus & probably Bjerkandera adusta. .

    not a yew obviously, but I couldn't find a general 'propping' thread, so felt here was appropriate. Sometimes if you leave the trees a couple of hundred years they may 'prop' themselves ! .

    rather impressive beech base...... .
  4. David Humphries
    Yes, Inonotus dryadeus .
  5. David Humphries
    bit of wind load and Kretzschmaria.... .

    Scleroderma citrinum around the roots of an old beech pollard from earlier today..... .
  7. David Humphries
    Helical twist here on a beech pollard significantly altered by the white rot of Ganoderma and the long term affect of wind load. .

    Kretzschmaria deusta infected beech failure. Fruiting not at base but within cavity at 3m. In my opinion, this wouldn't have been picked up other than by aerial inspection. The soft rot is evident in the core .

    birch & beech advantitious rooting spotted today......... .

    Brilliant ! Your invention is boundless Think I'll need to order a couple .
  11. David Humphries
    Nice shot ! .

    Watching my youngest open his presents on his birthday this morning. Can't believe he's 10 already ! .

    That's smart Tim. What type of pulley set up did you have for your climbing line attachment to the highline? Much bounce open it? Like the doors track .

    Great image Mario, fantastic light ! Can you see the redwood forests along the coast from a sailing/boat perspective? .

    Nice dual aspect on the filming Ziplining looked smooth. Always appreciate hearing why a tree of this size and stature is removed, was there any consideration given for reduction to manage the structural issues? .

    Thanks Reg, We're starting to put some together in to the rigging arsenal at work and hearing from someone who's got time served using them is very useful in terms of the comparison of pros and cons of the rings against blocks. For me (who hasn't rigged anything from up in a tree for eons) it's interesting to see the development from 3 strand topping strops to pulley blocks to rigging rings. Christmas seems to go on for a while in Canada then?

    Enjoyed the watch Paul, interesting selection of kit and techniques. Thanks for sharing. How's life in the east? .
  18. David Humphries
    Wow, what a mesmerising piece of time lapse. fantastic patience & vision .
  19. David Humphries
    .....or something form your 'zoo' collection perhaps? .
  20. David Humphries
    Well done, Xerocomellus (Boletus) chrysenteron it is indeed No not recent, thought I'd throw in an easy one to get us back up and running .

    Due to the delamination we took the opportunity to have a look below ground to see what the root connectivity was like with this particular part off the root crown. Not suprisingly the front buttress section had discontinued rooting some time ago but younger substantial latteral roots had developed inpart to compensate the loss. it turns out (having bumped into a local font of woodland lore concerning this particular site) that the tree had taken a substantial load during the 1987 gale which resulted in the split. .

    Above ground biomechanics included vertical scar tissue 60cm apart running up the tension side of the trunk to a height of approximately 2m. We listenend to the trunk/buttressess with a nylon hammer and discovered that the path side trunk face sounded delaminated. This was then confirmed via resistograph drilling that showed a drop off (2cm void) after 20cm. We felt that this presented itself as a hazard beam (crack) much like Herr Matthecks classic drawing .

    Had a closer look at an oak today for a colleague. Its a wood edge tree that sits next to a busy north London street & a well used internal woodland path. We'd carried out a 2m height reduction about 8 years ago. .
  24. David Humphries
    Would really like to see you filmed from the perspective a drone cam Reg. Wouldn't particularly care if it was tree killing or not. Must be a contact or three in the Americas that would see you as an interesting film project. Make it so .

    Melanine plaque of Armillaria Certainly looks like a load of Kretz fruiting bodies though .
