The tree itself appears to be relatively healthy, although the above 'Google map' shots seem to show it dropping its leaves earlier than other Acers in the area. The reason for our reduction spec was due to an area of dysfunction and associated decay at the base caused by Ganoderma pfeifferi. .

We pulled off a reduction job today due to concerns raised by the climbers of possible health issues in relation to working in the immediate vicinity of one of these masts and relay stations. A German study in to the effects of pulsed high-frequency EMF's (microwave) associated with close residency to these types of masts have highlighted the following symptoms in people living/working close by...... Sleep disturbance, tiredness, headache, restlessness, lethargy, irritability, inability to concentrate, forgetfulness, trouble finding words, depressive tendency, noises in the ears, impaired hearing, dizziness, nosebleeds, visual disturbances, frequent infections, sinusitis, joint and muscle pains, feeling deaf, palpitations, increased blood pressure, hormone disturbances, gaining weight, hair loss, nocturnal sweating, nausea. Other case studies have highlighted an increased risk of cancer. I haven't spent time reading deep into this yet, but I think we should all be aware of the potential health concerns. .

I'd forgotten about this old thread, some fine examples of phoenixed trees and branches. Thanks for the heads up Paul http://arbtalk.co.uk/forum/tree-health-care/7339-ents-make-move.html .

Yeah, I'd say these are pfeifferi. Young developing australe and applanatum don't have that lacquered/reddish colour, like these ones present. Give it a scratch if you come across them again . Ps, Paul I can't believe the AA haven't invested in sratchavision computer screens yet .

That's a good one ! Phoenix regeneration is one term given to the phenomenon I like to think of them as ents, slowly moving forward from its original spot.

Looks a fairly good shout for pfeifferi. Did you try scratching the top surface, to see if it had the tell tale 'bees wax' coating? .

not surprising as I was going through an odd thread title phase Should have just called it the Spheroblast thread ! http://arbtalk.co.uk/forum/woodcraft-forum/41799-beguiling-piece-tinkering-beauty.html .

and a rather alien looking pod of Scleroderma in the leaf litter of the beech pollard. .

also, the unusual occurrence of Rigidoporous ulmarius on Beech pollard in the bolling rather than at the base. http://arbtalk.co.uk/forum/tree-fungi-85.html Interesting thing here is that the bolling will have the brown rot of Rigidoporus as opposed to the usual white rot more commonly associated with Ganoderma species in these areas. .

Interesting find today whilst over at Burnham Beeches working on the pollards. The Red Banded Polypore (Fomitopsis pinicola) Pretty scarce in the UK, with only 45 records British Fungi - record details more gallery images (taken in Poland last year).....

That's quite hard to answer Matty. It's variable as they can take 2/3 years before they start flushing again. There are about 400 pollards left at this site and they have about a 6/7% mortality rate, which appears to be reducing. They've been re-cutting them now on 10-15 year cycle for the last 30 or so years. Somewhere in the region of 25 a year They'v all been subject to various levels of Haloing to some degree. So each tree takes time to react to the new levels of light they're exposed to, depending on individual vitality and decay. A large number have Kretzschmaria deusta. We've been involved since 2007 and work on approximately 8 pollards a year. From the ones we've been directly involved in, they appear for the most part to be fairly vigorous. We've come down from a couple in that time that didn't feel right and have subsequently fallen over during strong winds or heavy snow fall. Don't think that really answers your question though. .

Indeed .

Ah, ok Look forward to seeing them when they're in leaf .

Great shots Alec, are the twins the ones we've been speaking about? .

yearly visit to work on and around the splendid pollards of Burnham Beeches.......... .

I was thinking about 497 ?

Meetings with remarkable trees, the Arbtalk version.......before its sliced and diced for firewood ! Here be the Tortworth Sweet Chestnut. Layering well and becoming a small woodland in its own right Reputedly planted around 800 AD .

30 seconds more like ! .

so, are you having it removed is the question .

None taken, as you say, it is what it is. In my defence the deep vein thrombosis I suffered meant my leg was swollen and pretty useless for a good couple of those weeks. Standing in a line of OAP's for the next three months once a week getting klaxon and warfarin injected in to my stomach.........was fun .

I had one about 7 years ago, which took me 8 weeks to get back to work from. Mostly from a bad case of DVT Of course I'm not the athlete you are Mark ! Don't know about pre-op, but post-op I used a turbo trainer for a while to try and build up calfs, quads and knee muscles again. .

Right, I got the scale wrong completely. No idea .

Was it from a wound on the top side of the branch? Has a look of Pseudotrametes gibbosa .

Looks vital from these images. The failures I've noted with P. squarrosa on ash have all been trees showing notable decline in the canopy. Perhaps consider reducing the wind load potential. .

This list looks fairly comprehensive, which the author has put together from work by Lonsdale, Dujesiefken and personal observation. The latter bit is key imo, having a look at the differing decay types at different development stages is where the ever growing knowledge develops.
