Ryan,
A small borer should work. They are available in sizes as short as 6 inches. Will F. Blozan President, Eastern Native Tree Society President, Appalachian Arborists, Inc.

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? Best, Ryan
