European larch canker

[marcin]

Hi,

Recently I came at work across European larch canker, it's not on ArbTalk list. Is it because it is not significant?

 

Most of larches in this place with visible wounds (in crown and on stem), age 50 approx. Larch cover less than 20 percent. comes second after Scots pine.

 

My question is: should owner of trees consider any action?

 

From what I found, Lachnellula willkommii does not cause death of tress so removal is not necessary in my opinion.

 

Any other thoughts?

Thanks

L. willkommii not often fruits, but if it does, it is mostly on infected twigs or branches laying on the ground and on or near bark tumors (bulges) on trunks and branches, which are still on the tree. The mycelium not only causes bark cankers, but also affects the phloem. And its spores spread over short distance by birds visiting trees.
