Douglas-fir Hormone Study

Purpose

Trees to be thinned. When trees are one year older, taking out their leader to make them bushier, then harvest the trees over the next years until 1990. This project is to study hormone levels throughout the growth cycle of D.-fir. It is also trying to

Vigor Analysis of Douglas-fir Seedlings

Purpose

Seedlings will be planted at intervals of two months starting February 18-25, 1985 with final planting June 1-5, 1985. Survival and bud burst will be observed.
