Acute Oak Decline Disease

[RobArb]

Has anybody ever come across AOD in large veteran trees? If so whats the best form of management?

 

The tree i'm on about i think has got this AOD, done a bit of reading on the subject just not much, wondered if anyone has had first hand experience?

Forest Research - Acute oak decline

 

All the info you need here mate.......we have quite a few trees affected and the forestry commission have been carry surveys and monitoring. Still a relative unknown quantity at the moment. What we have been told is to leave any arisings on site to prevent spread.

very interesting:thumbup:

 

i take it OPM is getting worse?

 

we don't get much up here if any at all, can't say i've seen any larvae nests or even caterpillars once over the last 2-3 years

I kind of understand now why they are stepping off the attempt to eradicate and now just contain, look at the numbers for opm nests increasing year on year, losing battle

Is there another mini beastie that prey on OPM?

 

or would that be creating further problems?

Anyway back to AOD!

 

Is AOD in any way connected to phytophthora or is this a disease that is associate with decline?

im not wishing to come across all smart arse, but they really are paranoid about these bacterial bleeds, ive seen so many trees overcome this, chestnuts, beeches oaks, various versions of phytopfera etc.

 

Its like the old days of "THE DEMONS OF D!"
