On an even gloomier note, a death has occurred felling dead Ash in Petworth last week, don’t know much detail as yet but I assume there will be some update from Euroforest/FC/FISA  when they get their thumbs out of their arses, my thoughts are with the family.

I heard upon the grapevine that it was oak, and crushed by the tree rather than hit by a falling limb. Thoughts with his family too.

Not noticed any signs of recovery they look alot worse than last yr.

 

I reckon  atm

 

 

20% healthy no signs

60% minor signs of dieback @ tips of branches

15% half dead. (Whole crown effected, only a very few leaves left on many)

5%   dead.

I hope this is my first survivor of Ash dieback, the leader shoot and the 2 side shoots died last year, and I thought it was a goner, it was certainly slow to come in the Spring/early Summer, but just today I observed that it appears to have bounced back, with several vigorous 4 foot long new seasons growth.

I say that simply because none of the other affected trees have shown any sign of recovery  like this one has.

Wondered if someone with more experience than me can help. We look after a lake and the owner has told us his stand of Ash and Cherry has signs of Ash die back. After inspecting the trees,  the majority have no sign at all of any ailments. Among the 50 or so Ash trees, only one has any sign of anything like Chalara. 

We are in south Wiltshire which I think has little incidence of Chalara so far. 

The crowns are fine, looking healthy and totally normal.

The following photos show the crowns, the trunks typical of all the trees, then finally the one suspect tree. 

Is the last pic a clear sign of Chalara?

It looks more like bacterial canker to me.

[Stere]

Yeah looks like canker.

My conclusion here EdwardC, spec savers syndrome, if you ain't looking for it, doesn't mean it's not there. Not notice much here on Rail, and frankly could be a lot of strimmer damage ? Ash is a fragile tree, don't like reductions, big platter of fungal interest in it and not a long lived tree anyway. Genuine Chalara IS a problem in plantation, or avenues but like Massaria, I ain't seeing much of it. K

Should have gone to SpecSavers !

How many of these trees that are recovering, are coming back from drought induced stress and not Chalara?

Where are you in South Wilts. I’m on the wilts/Dorset border and it’s looking terrible around here.
