That sounds and looks very typical of ash dieback. Probably the most obvious symptom is young trees (especially saplings or coppice regrowth) with dead tops and normal looking growth below. It's very easy to spot when you get your eye in.

 

 

I am far from convinced it is dieback yet. Took. Couple of pics of that other tree, the one the top fell off a couple of years back (probably longer).

Zoom in and you can see the peeled bark and rotted centre. Tree looks as healthy as anything and has made strong new growth. I always suspected lightning tbh on that tree.

The great tragedy is it was all preventable, but yet again the industry big shots refused to listen to the practitioners (who really knew long before) that it was imminent and advised on how to stop it.

 

Unfortunately there is a vice like grip on commerce and the World trade organisation is all too powerful

I thought that the general consensus was that it had already arrived under its own steam before the infected nursery stock was imported?

I was on the downs around Arundel today and saw masses of dieback all over the place. Mostly on saplings, but also some mature trees showing symptoms. It doesn't look very dramatic and doesn't kill mature trees quickly but there's loads of it around.

 

Oh Ok . I am at the foot of the downs in the village of Lavant ( just north of Chichester ) and not seen any .

I'll be surveying West Sussex in the next couple of months. Any particular places anyone is concerned about, let me know and I'll take a look.

What sort of surveying are you doing?

I hope this ain't the daft question but I've had to drop a few mountain ash that have weakened just below ground level. Any ideas what's the cause

Ash dieback.

 

4 sites in each 10km square hants, West Sussex, berks, Surrey. Particularly looking for sites in the Bracknell area as there is chuff all ash up that way.

Strimmers whacking the bark off at the root does cause this . Possibility ?

[RichieR]

Thanks Stubby I was thinking the same. The first 3 definitely had been damaged by a strimmer but the last 2 didn't show any signs. They were healthy last year and then gone downhill fast
