Hi
strange question any one done this in a forest and did it work
ok reson for asking large block of trees
planted at about 600 per acre back in 96/99
high wind site so thinning down to 300 +/- per acre may have high risks
so thinking maybe ring bark the poor ones broken tops twisted etc
i have a mate who likes to build stuff so will make a machine to cut a 4-5 inch ring bark
or is chem killing a better way
seems to be a lot of thinking the root grafting would lead to eather the tree growing if ringbarked or if killed with chem the other trees will die
cheers
Not sure if I am following correctly here. Ring barking=girdling. Stand is located in Oregon? High wind? - coastal area? 19-22 yrs old. Should have been thinned 6-8 yrs ago. What is dia and height average? Might be able to wait some years and do a commercial thinning but probably not as volume may not be there with that many stems/ac. That said, girdling the trees down to 300/ac could leave half your stand as dead and standing, not a safe condition. Chemical application will leave the stand in the same condition. But cutting them down this old with no removal creates a bad slash condition. Honestly don't know what I would do at this point. In summary, I'm no help!
Hi Brad
yep girdling same as ringbarking
stand in in new zealand highcountry with high winds up to 60 mph in worst cases maybe avg 20 odd mph
i did quiz up a guy in NZ and he was of the same thinking of probs with heath and safety with number of dead standing trees
hopefull my maths works out ok
one area that trees growen in shelter range from 46 foot to 54 foot high 7inch to 10 inch bhd
they would be the bigger ones
on avg 96 planted 7-10 inch bhd and 33-45 foot 99 planted 6-9 inch bhd and 30 odd foot high
we have looked at 1 in 5 row thinning and pulling out timber price about 120 per cube meter for some at port with a 4 inch sed down side is wind tranks left by removeing the whole row along with some good trees
whole block can be logged by ground based gear feller bunchers skidders etc
fire wood log may sell for about 80-90 kiwi a ton not sure if at wood mans yard i would be guessing so it would be close to break even at that money But forest is also a carbon forest so if logs sold carbon has to be repayed to govt (it's a strange set up and add's a twist to foresty )

in a nut shell the trees lock up carbon and you get units for the carbon if sold/logged pay it back
cheers for your reply
