North east Scotland letham grange lots of fun really enjoyed it

Looks like one of those trees that would be great fun getting down, but the clear up would be awful.

Amazing tree and great photos too!

 

Is Dutch Elm disease carried by a beetle? and if so does that timber need to be treated or disposed of in a certain way?

(might sound like a daft question, but i'm learning lol)

[Tnarg25]

it is caused by an elm bark beetle which carries a fungus i think !!! when i first started in tree work any dutch elm timber was removed and supposedly burnt but now they reckon that the beetles are long gone and onto their next victims by the time the tree is dead !!

yes the clear up was awful i stayed up the the tree as long as possible lol !!

I'm not sure that burning the timber was ever required, the bark was stripped and burnt on site and back then most brash was burnt on site anyway (before the chipper).

Scolotyd beetle, scolytus scolytus lays eggs under the bark, (as soon as the bark gets rough enough for the beetle to take hold, coinciding with a height of tree of about 20-ish feet), and introduces a microfungus [usually] ophiostoma novo-ulmi. The tree then closes the xylem vessels in an attempt to contain the spread of the fungus, thus strangling itself.

I recon its down to cambium thickness not bark roughness.

[tommer9]

The relevance of the bark roughness is a theory of why the trees dont get hit for about 15-20 years. It could well be cambium, it could also be that the beetles apparently have a flight height of about 4-5 metres I have also read, and that until the tree reaches this height, which coincides with the bark losing its smoothness, it is not susceptible to the beetle.

I think that there is probably a certain amount of indecision about the causes......
