Inonotus on Ash....

[sean]

I refrain from asking so many questions with regards pests, diseases etc.....dont know why.....pride i guess.....feel like an idiot for not knowing......but I am slowly realising that for me to go where i want to go.....and to satisfy my first for knowledge (and accepting that compared to you guys this is all relatively new to me) I HAVE TO KEEP ASKING!!!

 

So.....i'd like to find out as much as i can about inonotus (especially on Ash). This is mainly because i have come across quite a few trees with it lately. With regards private clients I have had to draw up management plans.....fell/reduce whatever.

 

My understanding of it on Ash is that it is a dangerous simultaneous white rotter......which will often require quite a heavy reduction and in other circumstances pollarding or fell. This week I advised 1 pollard, and 1 fell......I also carried out a hefty reduction on a big Ash that had a big limb failure in Kensington gardens.

 

So some questions.....Hispidus canker.....is this the bark necrosis associated with this fungi?

 

After carrying out a reduction on a hispidus affected Ash....(pruning into 'sound' wood.....is there a high chance that fungal spores will then infect a limb lower down from that, that has been cut out?

 

Any info actually would be much appreciated.

 

Sorry for the reams of text:blushing:

Sean, dont be shy, and dont feel it reflects on your abilities, this area of discussion/learning is one where even the BIGGEST pros make massive errors so join in and get out what you put in be that answers or questions, its all good. regarding hispidus, I dont EVER panic, it will be obvious when panic is needed in hispidus! but will elaborate

 

off to get some pics!

Cheers Tony.......i thought you did one of your threads on hispidus but searched all your threads to no avail:confused1:

I would not put Inonotus hispidus in the highest risk category at all, part of the ash "tree species specific ecosystem" and these images show just how resilient Ash are to the decay.

Interesting Tony thanks......

 

The one i looked at today had very similar characteristics as your one but had a lot bigger/heavier laterals too......a couple of which overhang gardens garages.......

 

Pretend your photo is mine........There were brackets above the red arrow i have inserted on limbs going out at 45-60 degree angles. Evidence of cavities/woodpecker holes and canker. The client would love to keep the tree as much as poss so i thought about reccommending a heavy reduction to approx height of my red arrow and then re-pruning every 5 years or so? How does that sound?

 

Obviously it is your opinion without seeing it.

p.s. There is lots of growth below this arrow:001_smile:

P.S again....surely the tree in your example would need reducing given the proximity to a road:confused1:

[Tony Croft aka hamadryad]

hispidus is a natural pollarder, a 30even 40% reduction is ideal and the tree can be as you say re pruned and retained almost indefinatley if no other complications occur

Yea thats what i thought.....and what about Hispidus canker?? Could you explain that for me please.....sorry.

I chose that image for good reason, its had hispidus for a LONG LONG time, had it failed and drawn attention to itself? no, a few minor limb losses that where probably mostly dying back and smashed to bits on the verge drawing little if any atention to it.
