Creator:: Lavender, Denis P. and Engstrom, W. H.
Abstract:: To determine if squirrels (Sciurus douglasii var.) cut cones before the seeds are ripe, a series of collection points was established in the Willamette Valley and the Cascade Mountains in the summer of 1954. The areas were inspected at intervals during August, September and October of 1954, and freshly cut...

Abstract:: The spruce budworm is an important enemy of the Douglas fir-true fir forests in Oregon. It can be successfully controlled by aerial spraying with DDT. The influence of air temperature on spruce budworm growth, the growth of the host, and interrelationships between insect and host were studied on 15 areas...

Abstract:: Disturbance processes of various types substantially modify ecosystem carbon dynamics both temporally and spatially, and constitute a fundamental part of larger landscape-level dynamics. Forests typically lose carbon for several years to several decades following severe disturbance, but our understanding of the duration and dynamics of post-disturbance forest carbon fluxes remains...

Abstract:: For the past ten years, Douglas-fir on the Oregon and Washington coast has shown a progressive decrease in height and diameter increment as a result of Swiss needle cast, which is caused by Phaeocryptopus gaeumannii. In this contribution, we discuss the effects of silvicultural operations on Swiss needle cast and...
