Growth of ponderosa pine by keen tree class.

Abstract

Every forester who works in the ponderosa pine woods is impressed by the tremendous range in size, quality, age, and thrift of the trees found in the virgin forest. So great is this variation from tree to tree that stand averages mean little to the timber marker trying to select trees of high value and insect risk for cutting, and at the same time reserve for future harvest the trees of low carrying charge and rapid growth rate.
