Thanks Andy. Should of got Jeremy Barrel on the case, he has a soft spot for yews (and Caedars) Let's us know how the goes down .

What's the story around their removal Andy? .

I'd imagine this oak has witnessed a great number of firey skies in its 450 years. .

That would be my guess too . -

Hello Billy I've noted Heterobasidion annosum continuing to fruit on many occasions on dead stumps & trunk snags (which would suggest to me that it is indeed feeding and going through its life cycle from being parasitic on its host to being saprophytic. .

Hello Leonie Nothing really to add to the books that you've already listed & I don't know of any specific studies or anything in text more recent, apart from perhaps the Arboricultural Associations Fungi on Trees An Arborists Field Guide, (Guy Watson & Ted Green) which lists P. squarrosa as affecting the stem base & principal roots resulting in an intense white rot with evidence of a selective delignification in its early stages. I've found it to be a relatively slow decay of standing trees which can lead to wind throw. The graffitied one below is still standing with a full canopy on a field edge having had the association for a good number of years, whereas the second image was from a heavily decayed & decliining woodland ash that has subsequently failed (during high winds) since the image was taken. .

a balanced approach taking in to account what's already on the site. I do however strongly believe its down to those of us 'directly' involved in the removal process (both from the public & private sectors) to inform the owners or those that consult, of the awarenes & importance of habitat (whether it is required on a specific job or not) Its an easy option to just fell everything and process it to be left on the floor or to go as firewood/mulch etc..... Above is a general comment, not directed at you or this situation Tim .

Very sad news to read. Walter you were an inspiration and a big influence on my early career in Arboriculture I often remember with fondness our training weeks with you at Hampstead & Epping. My thoughts are with you. Kindest respect and regards David

Dead wood volumes good for iggly wigglies, (scarce, red data listed & threatened) ................firewood not so much. There you go, habitat diploma 101 in less than 20 words. Even the most HAVS inflicted saw buzzer should be able to understand that Let's get Mr Pine to comment further on 'his' thread Nice felling skills Btw .

Personally I think I say/show enough here at Arbtalk, at seminars and in articles to get the message across from my perspective. It gets a bit boring after a while It's up to others to continue with it themselves or stick with the status quo. .

become an AA member and you get the benefit of four magazines a year and the journals plus a host of othe fantastic benefits Not to mention the fact that you'll be supporting our voice across the associated industries .

afraid not, looks like you'll miss it. .
-
I believe there's a place for biodiversity, firewood and product from trees, sometimes needs a balanced approach. If you're interested you could read my article in the AA magazine which looks at dead standing trees from the biodiversity angle. ( or you could ofcourse just use it as an accelerant in your wood burner) .
-
I can't tell the habitat quality of the woods where these trees were felled, (perhaps Mr Pine could indulge us) but I don't see sticks of the same size and volume of standing dead wood which is a particular niche habitat for inverts, fungi and other associated ecology. Perhaps out of camera there is? .
-
I was thinking Tricholoma species for the white ones, but the gills appear to be decurrent which does't fit. The brown ones look like a Collybia species from what I can see of the gills. Not sure on either tbh .
-
No option to leave as standing dead wood at the height they were felled? .
-
Try reading the forum rules We try and keep on top of them to keep the site running smoothly Rule 2 applies here http://arbtalk.co.uk/index.php?pageid=forumrules .
-
It's not an Armillaria species For a good shout at an Id you really do need to show the gills or pore layer from underneath the cap. .
-
this information perhaps buys this particular tree more time, before any further works require proscribing. .

Well, there's been an interesting development regarding the Id of the fruitbodies, I perhaps should have waited to post this thread until confirmation, but a good acquaintance of mine (Andy Overall) who's a field mycologist, has had a look under the scopes at the micro features of a couple of specimens from the lime site. The two species vary in some of their macro features but are pretty similar with regards to their size, colour, stipe & gills. The absolute way to tell them apart is via the basidia clamps, or lack of (A. mellea has none) The basidia are the long cucumber like structures where the spore develope and are then released from. The following images show; 1st shot, the clamp(s) attached to the base of the basidia (lhs of the blue line points to one) 2nd, the spores 3rd, the scale cells and spores. .

an interesting combo on me favourite monolith, which also hosts Meripilus, Daldinia & Coprinus however yesterdays show were the fine & dandy Gymnopilus junonius the spectacular rustgill & Abortiporus biennis the blushing rossette .

Excellent .

I've also noted occasions where trees with Armillaria have lead to a wind throw situation but the tree (pear in this instance) continues to produce leaves, flowers & fruit (albeit in a rather more relaxed position) .
-
We had three young limes succumb to Armillaria at the same time over a relatively short period 4 years ago. Their decline was rapid & aggresive, but there have been no further out breaks of fruiting or decline of the immediately surrounding trees in the following years. .
