My mate showed me this oak last week so I went back today to take some pictures. I thought some of you might be interested... It is a Quercus petraea showing extensive brown rot caused by Laetiporus sulphureus. There is a small cavity in the base, extending less than a meter up the stem. The main, larger cavity starts at around shoulder height, and extends approximately 2 meters up the stem. There are several fracture wounds in the crown which at some point will coalesce into the main cavity (as will the lower cavity). The tree is in the middle of a mixed stand of broadleaves and although sheltered from the wind for the most part, its upper crown does stick out above the other trees. I think the tree would benefit from a reduction to bring the crown down to the same height as the surrounding trees, as well as some deadwood removal in the crown. (I should point out that I am not managing this tree, nor have I been asked to- just want to hear other people's opinions.)

Came across this large Inonotus hispidus bracket on an ash today- first time I've found this one so i thought I'd share. One of the ash's two stems has already failed and the tree shows a lot of swelling around the base.

smile!

well then, considering the new low price... sold!

to be fair this time 3 years back, i didn't know how to start a chainsaw let alone safely crosscut large stems. we all have to start somewhere. at least the guy is asking the question instead of blindly going into it without any idea of what he's doing
-
is it any good? its one of those books i think i should own but i have heard mixed reviews on it
-
beaten to it twice in one thread! time to call it a day i think
-
alternatively, fell the stem onto some lengths of branchwood, thus elevating the stem, allowing you to cut all the way through without touching the ground with the saw
-
cut it half way then turn the stem over with a felling lever, if that is difficult for you cut it half way, turn the stem a quarter and follow the cut, then turn another quarter, continuing to follow the cut. the cuts should match up. check your chain is sharp too (equally on each side)

View of the Blackmore Vale off Bulbarrow, Dorset
chris cnc replied to Matthew Arnold's topic in General chat
nice view! -
cant say i agree with you but im sure you're not alone, considering their popularity over the years!
-
what a cracker! on beech?
-
i'd remove as much weight as possible before tensioning the guy line, but yea i see your point you'l still be left with a hefty bit of wood! i've got some 4 ton polyprop you could borrow?

Foundation Degree Arb at Myerscough- Prep!

cheers guys will check those books out, bought "principles of tree hazard assessment and management" recently which i am thoroughly enjoying -
guy the tree to a ground anchor (possibly from one of the main branches which are now pointing "up") situated in line with, and several meters behind, the stem? then release from roof using mewp, and release tension on the ground anchor while winching/ pulling the stem away from the building with a second line. just an idea although i have never done anything like that before!!
-
get your boss told. you'll be kicking yourself if you have an accident- or worse, you might not be able to kick yourself...
-
the most no- nonsense thread ever!
-
dear me wheres the blue polyprop when u need it eh?
-
in fact, you could just leave a strong throwline up there, and install a fresh line when you get there, eliminating the need for a particularly tough rope
-
lol exactly! surely there could be a way to have a permanent line installed at least for part of the tower? perhaps with a protective coating, or even a wire core to protect from the elements. then the climber could tie in a friction hitch at the bottom, and ascend using the ladder, taking in slack as he goes??? surely it's not beyond the realms of possibility, and it would be a LOT safer! even just a single line, to which could be attached a cammed ascender etc
-
nicely done i bet freeing the stem from the roof was an exciting moment haha
-
hahaha trees prefer Ryobi cos they dont cut
-
your post shows a fundamental lack of knowledge of trees and the arboricultural industry
-
there is a pic of the scene in the "tonights wind" thread, on a link. havent heard of any incidents near here yet thankfully

newton hall lorry. she's a character like telling me all about her travels in canada back in the day! the "tree surgeons" also told her that "it is very difficult to get a flat cut with a chainsaw"
