Abstract

A 60-year old red fir stand with 23,950 stems per ha was thinned to five stand densities. Thinning occurred in 1972, 1976, and 1980. Height, DBH, and crown characteristics were measured seven times at four- to seven-year intervals from 1972 to 2002. Tree rings were measured retrospectively to determine growth of individual years. Periodic annual increment (PAI) was analyzed for quadratic mean diameter (QMD), height, crown volume, and basal area per ha. We found significant difference for all variables among thinning levels and among measurement periods (P
