    The black crease (in the image of the Beech and not the maple) is where we scored and plunge cut the remnant of the girdled root to partially severe it rather than tear apar the two grafted volumes (girdle root and buttress) Whave have had more confidence to remove large girdles, but only where there is some 'wiggle' Our urban soils are rife with Armillaria just biding their time for dysfunctional points of ingress. If I get the chance I may keep an eye out for a woodland example where I would be happy to 'experiment' with exercising a large SRG.

    No idea, but pretty interesting ecology. Hopefully someone will have a pointer. Thanks for posting.

    Yes, it's the size of wound surface that would develop, as all the girdling root material is anastomised with the parent root system and would just leave no bark behind to protect the lower buttresses. If any of the girdler was seperate from the parent material I would have considered removing it. .

    We had a look at a root girdle on a maple today that was adjacent to a single fruit body of the giant polypore (Meripilus giganteus) Good canopy vitality. No significant decay of the contemporary root system by the Merip at this point (suspect the association is from a colonisation deeper underneath the old tap root system) but the girdle has constricted a couple of the buttress roots. The girdle is too developed to remove, so will adopt a watching brief on the vitality of the canopy and the associated buttresses.

    Hello guy, there's no text in your post above?

    Nice find Bill

    Don’t think it’s the room temp Gary, this left a spore print overnight yesterday in a very similar environment and came in from the cold. Your mushroom specimens are probably just shy? The brackets are just perennial and not at their sporulating stage or are just spent.
  8. David Humphries
    Not sure, definately not cheap but worth it, (£200 rings a distant bell) but like Gary said, he's very entertaining and I remember coming away both times with a number of biomechanical processes having clicked into place.

    So which film are these pollarded London planes from?

    The heads up is on page 26 and says that after a four year break, Claus Mattheck will be delivering his final lectures in the UK on the 12th and 13th of June at Loughborough University. His new book 'Pauli Explains the Form in Nature' will be included in the delegates pack. Mick Boddy/Symbiosis Consulting will be hosting again and booking starts in January.
  11. David Humphries
    Yep, P. ostreatus
  12. David Humphries
    Nothing that you haven’t gone over already but I’ll send you the pdf’s anyway. Yeah saw that Mattheck was returning for a farewell performance, I probably won’t do the lecture as I’ve been to a couple in the past. Mr N might.

    I've got a copy, if you send me an email I'll scan the pages for you. Is for the Lev 4 Diploma, or something else? [email protected]
  14. David Humphries
    Closing date for applications is 29 Dec 2017

    That's cool Gary, any chance you've taken one for a spore print?

    definately more fun than anchoring on to this particular tree ( believed to be about 350 years old, which is quite a lot for a Beech) The site has access to a tracked Tuepen, but the trees on quite a slope and the reach is too short to manage the far side of the canopy.

    Hi Pete, yeah i think Ali and Rob will probably tie in and terminate straight on to the plate to simplify the system when they actually do the job. I wasn't on it but Ali reported some bounce but not excessive. We're aiming for some slack in the system to reduce some of the tension. Last time we ran this system (using patron) there was a little too much bounce hence going to a more static line.
  18. David Humphries
    Prepping with a new set up for a proposed reduction on a very decayed veteran beech pollard that is to remain as standing dead due to a rare lichen. (can't really climb it due to Meripilus at base and Kretzschmaria and Rigidoporus in the top of the trunk and a mewp can't get near it) Thanks to advice, we are moving from one single line (that we've used before) to two static lines that can be independently lowered. Set up is 2x 70m Teufelberger ultra static ropes tied/karabinered to a bat plate, srt on to the bat plate. Pulleys at the top of both anchor trees.
  19. David Humphries
    No idea

    ......radiation ! like Stubby says, probably both I would think.

    I've read about this phenomenon in various books* over the years but not knowingly witnessed it until recently. Here's a good example on London planes * The Physiological Ecology of Woody Plants By Theodore T. Kozlowski; Paul J. Kramer: Stephen G. Pallardy

    We are now looking to fill an exiting new opportunity for a 2 year apprenticeship working with our Conservation Arboricultural Team based at Hampstead Heath in north London. Application link below https://www.findapprenticeship.service.gov.uk/apprenticeship/-216360 For a flavour of the type of works the successful applicant will likely be involved with please click the video.

    The recent cold/wet weather is resulting in a fruiting of various Tremella species. Here, T. foliacea (leafy brain) on an oak limb.

    a fair splattering (old colonisation) of Auricularia mesenterica (Tripe fungus) on a parkland ash

    Fine collection of images Rupert. Likewise, it's a good way to put a collection of fungal highlights together https://www.instagram.com/mycoappman/
