A method for determining the onset year of intense browsing.
A survey based on browsing related architectures indicated that browsing level had increased at the Mt. Haggin Wildlife Management Area. We describe a technique for determining the year in which the increase in browsing level occurred. The technique is based on the analysis of stems old enough to ha...

Haggin Wildlife Management Area. We describe a technique for determining the year in which the increase in browsing level occurred.
