Will/Ryan- I'm too old to be intuitive on metric/standard conversion, but wouldn't 50mm be about 2 inches? I'm not sure I'd be comfortable coring 2 inch diameter trees...wouldn't the corer with threads approach 1/2" in diameter? With little wood left on each side to 'strengthen' the coring point, I'd think that it would have all the elegance of an exit wound left by a 38 caliber S&W...;>)

"No sympathy for apathy" From: [email protected] [mailto:[email protected]] On Behalf Of Ryan McEwan Sent: Wednesday, January 06, 2010 7:27 PM To: [email protected] Subject: [ENTS] age of small trees. techniques? Hi all, A former advisee of mine has moved on and is now working on a study of forest dynamics on Mount St. Helens. He is working right at tree-line. He would like to age the trees, but he is not allowed to destructively sample (cut) them. The diameter of many of these trees is 50mm. YIKES!! That is small. He asked me for advice on how to do this and I dont have a the foggiest clue. ENTS to the rescue?
