Regeneration patterns on some modified staggered-setting clearcuts on the H.J. Andrews experimental forest

A survey of natural regeneration of Doug1as-fir and associated species was made on 15 staggered-setting cuttings four and five years after logging. These areas were on the H. J. Andrews Experimental Forest...
Growth behavior of Douglas-fir reproduction in the shade of managed forest in the interior Coast Range of Oregon

During the past 20 years, repeated thinning of a Douglas-fir forest, now 65 years old, has allowed desired limits of basal area to be maintained. In the process, the understory environment has altered...
Comparative rates of CO₂ production from the forest floor in the Douglas-fir ecosystem

To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ...
Early stages in plant succession on Douglas fir clearcuts on the Mary's Peak watershed near Corvallis, Oregon

This study has been concerned with the patterns of vegetative
