Ash Disease

[TommyD]

Can some one tell me if the timber from ash that has been felled in the UK because of this disease is badly affected by the disease?

Timber is unaffected but need to burn any waste (bark/leaves ect) to comply with handling affected trees.

I not seen any recommendation to burn leaf litter from infected trees, who is telling us to do that now?

 

I gather if the ash trees are felled before too much die back then they should still be fine for firewood. Secondary infection with something like honey fungus can ruin any wood.

 

From my own woodland I'm starting to notice dark patches in the trunks of infected trees I'm felling and some of the tops of badly infected trees are rotting off. As it's for my own firewood supply it still seems useful.

 

There's a bit at the end here that suggests you brush off any leaf and shoot material from logs before moving: https://www.forestresearch.gov.uk/tools-and-resources/pest-and-disease-resources/ash-dieback-hymenoscyphus-fraxineus/chalara-manual-2-managing-ash-trees-and-woodland-including-logs-and-firewood/

Clearing leaves may disrupt the fungus’s life cycle and slow the impact of ash dieback.

Where appropriate, you should advise clients with ash trees growing in open and urban areas to remove all ash leaf litter in the autumn/winter. The leaves should be burnt, buried or composted.

It is not necessary to fell or reduce uninfected ash trees as a precautionary measure. Uninfected ash trees should only be pruned or felled to meet other, unrelated management objectives.

I gone a licence which allows us to burn any waste when milling

Thats only a recommendation ,and the word may is used in the first paragraph.

There are no movement or handling restrictions on affected timber., felled timber from commercial sites is being moved around freely , including to export markets.

“Composted” suggests leaving them where they land! [emoji849]

This is what we do as advised by euro forest 3 years ago when looking into buying diseased timber. (trees)

Perhaps you were, but it is wrong to suggest it is a necessity to comply, thats just not the case.
