Was it growing in a Butress and were there any more around the base? It looks like old sterile Ganoderma brackets IMO.

yeah, i dont think it was daldina, as it was brown when i cut a little bit away. yeah and it was growing in a butress, i'll have a look at gandoderma, see which species it may be

[omahaalex]

its for a tree report for college, i'll just go with Ganoderma spp or austrle?

 

This is selective delignification, and on oak, which is a good compartmentaliser, the tree is 22m in height 89cm dbh 10m inside a woodland quite sheltered with few targets. i cant think of many recommendations really, any other things to take into account?

 

it has a low live crown ratio and a low H/D ratio - shouldnt be a problem in a sheltered wood?

 

Anyone know of decent material for tree report writing?

 

Cheers
