Tree being taken out due to subsidence [ame] [/ame].

Liked the simplicity of the capture Tim, nice one .
-
Yes, Daedaleopsis confragosa saprophytic on the dead branch .
-
Thanks Dobson Gardeners on site are a bit precious about their grass and shrubs, plus as we don't take many trees out the opportunity to keep in practice with zipping is good for us. .

believe it to be plain old bignoniodies .

Hello Kiwi, here's an little anecdotal story & observation around Catalpa to help enthuse some hope....... This specimen developed a significant fault in the main union from a strong wind event. We were really only left with two options, fell & chip it or 'sensitively' reduce it The subsequent 'reduction' was not really in line with our British Standards to be honest, (although an update in the annexe which regards to the needs of poultry, should be a serious consideration) but apparantly the chickens who were enjoying the shade directly below it were not too keen on waiting for a replacement to mature and provide a similar service So with the the right growing conditions (and possibly a whole heap of chicken waste) the species appears that it can be vigorous and produce a reiterated and fairly globular canopy in very little time a periodic hair cut should keep it in order .

Smart

Should be mightily impressive in another few years...... .

Well............perhaps a little over three years .

Can anyone identify the cause of these deformities?

Managing Trees with Decay & Dysfunction
David Humphries replied to David Humphries's topic in Tree health care
Howdee Nick, It came down just before the new year. Haven't come across the inscription yet, it may be underneath one of the fallen sections. We'll keep an eye open for it. As you know, we left the majority of the canopy weight away from where the public had open access, but that has probably led to its early demise. We would have liked to have had the opportunity to have reduced more of the branch crown but it was only last worked about a year ago. Just not enough time and opportunity to bring all of these dead trees down in a more controlled manor. We had very little tree loss during the weekends high winds but expect an increase over the next 48 hours. How did Harrow fair ? . -
Managing Trees with Decay & Dysfunction
David Humphries replied to David Humphries's topic in Tree health care
We've been trying to bring this declining old beech down slowly but the combination of Meripilus, Ganoderma, Polyporus & Kretzschmaria have done for it. Most of it is now on the floor with only a small percentage of the original dead standing volumes retained as a monolith. .

Managing Trees with Decay & Dysfunction
David Humphries replied to David Humphries's topic in Tree health care
Lost an ongoing battle with time & the ravages of nature. first & third shot were taken in 2008, others today .

I agree with Sloth .

Interesting read, thanks for sharing Jules. Cover image looks a bit like Gymnopilus junonius rather than a typical Armillaria sp, but perhaps just the way it's printed. They are a bit similar. .
-
I would tend to agree that the lists should not be taken as being species that are completely resistant to Armilaria. They're more likely to show some resistance compared to others. .

The RHs list given above is the most complete I've come across also... Page 142 in my copy of S&W but that's an old one. This list below is from Paul Hamlyn's 2001 article entitled - Honey Fungus - Friend or Foe? 'Resistant plants' .......Box elder, Californian black walnut and yew seem to be virtually immune. Other resistant species include Grand and Noble fir, bamboos, hornbeam, beech, ash, Common ivy, junipers, larch, Cherry laurel, oaks, False acacia and whitebeam .' Not as extensive as the RFS and Strouts and Winter lists .

Next time you fell one at Exning you should get the committee to commission one. That would 'grace' any cricket ground : .
-
Well done, that's a really nice memorial. .
-
Glad to hear that this didn't turn out any worse than it did. Looks like the bus was parked outside the school at the time of it being struck. Makes it a pretty high target area. Apart from the obvious wind (any idea how strong it was at the time?) did you find whether it had any specific basal decay/structural weakness? .

Large Scotspine opinions please
David Humphries replied to Stephen Blair's topic in Tree health care
I think this tree will have a brown heart rot (possibly the reason for the presence of adaptive verticle growth ribs) and that the discoloration may be exudate and/or a bacterial type slime/gum flux that's associated with the dysfunction. Likely that there will be some root dysfunction also. A 10cm trim with bonsai sheers from the upper canopy should do the trick . -
