First one I would say are new incremental strips from compression wood being put down faster than tension wood (my opinion) and second has been eaten by wood beetles, and I can tell he doesn't look too happy about it:lol:

First one, looks like abnormal growth stresses causing the rippling, doesn't seem like mega compression, definitely increment strips because of fast growth though!

 

Second lot, if that's elm it could very well be Scolytus multistriatus that caused that.

I came across a tree exhibiting some interesting tell tale signs today, a beech again, but not a compression fork. Any ideas what is going on here?

 

this one is a little hard to explain without using copyright images!

 

basicaly we have both rapid incremental growth forming compression wood (indicates high stress) but we also have a comlex scenario that basicaly involves a notch stress which means that the notch at the base of the limb creates lines of buckles at 45 degree angles and forming square patterns often in the bark.

 

cool images fella, couple of realy good posts from you:thumbup1:

Here we have a "barn door failure" trying to occur. Wind exposure via an open field and prevailing winds being funneld down a Lane directly onto a limb that is trying to outreach into the light from the shady side of the canopy (photo-tropism, overriding auxins) in a weakly apical dominant species, Acer campestre a.k.a the field maple.

 

A footpath and busy lane directly below the limb, and clear signs of stress fractures all through the canopy so a sensible reduction done to alleviate streses in the canopy.:thumbup:

Good sized capestre.

 

good on the clients to accept a spec of retension on a decent indigenous species :thumbup1:

 

 

 

.

 

there wasnt an issue regarding retention, the fault hadnt even been picked up on, the reduction was due to be done for light reasons anyways. You should see what we had to do in the back!:blushing:
