    Thanks to you all for your kind wishes There zooms by another hectic year Here's hoping for another equaly engaging year ahead .

    Fine shots Jules, great morphology in the developing one. Tree dead/dying? .

    Cheeky so & so's, I'll have you know that I'm a youthfull 45 and not a day older ! Was born on the day that Armstong took off for the moon no less. The world was watching one giant step for mankind, whilst my old man was watching his poor wife screaming that if he ever touched her again they'd be blood shed very good Paul, but perhaps a simian holding a fungi would be more appropriate Cheers fellas .

    Good heads up, thanks. I'll share with our tree health group at work Makes you wonder about the susceptability of 'bred' trees to organisms that perhaps a healthy 'unadulterated gentically pure' tree may be able to tolerate ? .

    No repeat reduction planned as yet. Continue to monitor annually. Do you mean Perenniporia rather than Rigidoporous? If so, then I can't say I actually know as I've only noted failures associated with Perenniporia on ash and not robinia.

    I don't really know Jules, with out taking core samples or utilising a resitograph to measure the extent of decay before & after then I'm in the dark. For me its about the stability and the vascular health. This one appears to currently have both. .

    Doh ! it's me age ! .

    here it is 3 years on, from earlier today.... .

    Robinia here from 2011 that had/has a significant colonisation of Perenniporia in both the basal & upper trunk regions. There was also an instance of trunk vandalism. We got our then apprentice, to do his first reduction. A bit heavy handed and a bit inter-nodal in parts but thought he did a decent job, and got the required amount of canopy removed. .

    Hopefully you've now got enough feedback on your original thread ? .

    ........having said that, I've just spent the last 20 minutes trawling through the 427 records of Ganoderma resinaceum on the Fungal record data base and can not see it associated with ash Its listed as being associated with oak, beech, hornbeam, horse & sweet chestnut, elm, acer, willow, birch, robinia & cherry. Some of those are over a hundred years old and maybe questionable as are the records of it on pine & yew British Fungi - record details so, you either have yourself a first for the uk (I don't think I've noted it on ash before).........or its Perenniporia fraxinea .
  12. David Humphries
    like this one below and the next which shows older & younger bracket forming, which has a cocoa coloured spore dusting over the bracket surface (unlike Perenniporia which would have a white spore dusting) .
  13. David Humphries
    Yep, I would say that you have Ganoderma resinaceum The lighter fawn coloured rim on your image is the new forming bracket, it will turn darker and reddish as it matures. .
  14. David Humphries
    Thanks Paul Will be interesting to follow any related research over the next few years. Note to self, get more soil samples taken ! .
  15. David Humphries
    Hi Paul, did Glynn allude to whether the application of additional carbs in the rhizosphere attracted the mycelium of non-beneficial fungi, like Armillaria for example? regards David

    For information..... HSE Tree work e-bulletin - Issue 6 .

    I plan to be flexible with the phasing of any future retrenchment on this one Guy. If it looks like it shutting down over the next couple of years we'll either go back and carry out the next phase or make a decision on managing it down as a dying standing tree/monolith. Personally I feel that the end weight removal will help it to manage its energy more toward foliage production rather than biomechanics.........we'll see. .
  18. David Humphries
    It looks to be Ganoderma resinaceum. Though you would more often find Perenniporia fraxinia at the base of ash Can you get a wedge shaped slice from it showing the flesh and pore layer ? .
  19. David Humphries
    Vid says not available in the UK, August ? .
  20. David Humphries
    Is it possible that the 'abrasion' could have been from a previous unreported branch failure that impacted on that part of the trunk? are skinks a protected species Guy? .
  21. David Humphries
    I've stood back a little too long with similar cases in the past, so felt this one was in need of a little help with the retrenchment process to aleviated some of the weight in the limbs. shot of Conrad & Michal doing the do........ followed by a series of before & afters taken fromthe main cardinals...... .
  22. David Humphries
    decent aged oak that is starting to naturally retrench. Probable Laetiporus sulphureus colonisation suspected .
  23. David Humphries
    Very nice work Is there anything specific going on with the unions? Or just lightening the load? .
  24. David Humphries
    Have yourself a great break Paul. Bet you've clocked up some milage through work this year, well deserved .
  25. David Humphries
    Ideally Lee, I would have liked to just have mulched the entire surface of this tree (much like the Pear in the 'to mulch or not to mulch' thread) but the local management were in opposition to the idea due to concerns that the mulch wouldn't stay put because of the slope it's on and being next to a path. I'm sure if I'd tried harder I could have persuaded them to allow a containment barrier to hold the mulch but it wasn't getting through at the time. Did you mean Jesus 'green' in Cambridge, the bit next to midsummer common ? Did you do the work or was it just the recommendation? If so I might nip down and have a look-see. Any scope for amelioration down under? .
