Abstract

How old is this tree? Or that one? Unanswerable questions to most people, unless they are there when it started growing, but with proper techniques, equipment, and a bit of skill (or luck), it is not so difficult to determine the age of a tree. Because trees grow in girth by the addition, each year, of a layer of wood just inside the inner bark, these layers can be counted when they are clearly exposed. We usually see the layers exposed as rings on the surface of a stump, hence the study of aging trees is referred to as "tree-ring" analysis, instead of tree-layer analysis.
