Forest structure and regeneration in the Tsuga heterophylla - Abies amabilis transition zone, central Western Cascades, Oregon

Creator:: Stewart, Glenn H.
Abstract:: The dynamics of stands in the mid-elevation old-growth Douglas-fir (Pseudotsuga menziesii) forests of the central western Oregon Cascade Range were investigated using stand structure analysis. Trees with different growth rates were commonly present in the same stand, which resulted often in a weak correlation between tree diameter and age. Thus,...

Habitat relationships of birds and young-growth Douglas-fir in northwestern California

Creator:: Marcot, Bruce G.
Abstract:: Ninety-one species of birds were surveyed in grass/forb, early and late shrub/sapling, pole, and medium sawtimber stages of young-growth Douglas-fir in northwestern California; patterns of bird distribution and abundance were related to habitat conditions and even-age silvicultural treatments. Seven species (band-tailed pigeon, western wood pewee, dusky flycatcher, western bluebird, fox...

Influence of interplanted and pure stands of red alder (Alnus rubra Bong.) on microbial and chemical characteristics of a coastal forest soil in the Douglas-fir region

Creator:: Chen, Chi-sin
Abstract:: Chemical and microbial analyses were made at four seasonal intervals on soil horizons under red alder, conifers, and mixed alder-conifers at the Cascade Head Experimental Forest, established in 1937 by the U. S. Forest Service near Otis, Oregon. Microbial analyses showed that although plate counts of molds and bacteria fluctuated...

Isoenzyme polymorphism in provenances of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco var. menziesii)

Creator:: Yang, Jenq-chuan
Abstract:: Genetic variability in natural populations of Douglas-fir was studied at molecular level by investigating the variations of some primary gene products, i. e. enzymes. Using the techniques of disc gel electrophoresis and biochemical staining, the isoenzyme patterns of leucine aminopeptidase, esterase and glutamate oxaloacetate transaminase are characterized in young seedlings...

Silvicultural impacts of sheep grazing in Oregon's Coast Range

Creator:: Leininger, Wayne C.
Abstract:: A three-year investigation was conducted during 1980-1982 to evaluate the potential of using herded sheep as a silvicultural tool to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest in May soon after bud break. Averaged over the 2 years of grazing,...

Simulating Effects of Genetic Tree Improvement on Growth and Yield of Coastal Douglas-fir

Creator:: Joo, Sukhyun
Abstract:: Estimating volume gains in genetically improved stands at rotation age is challenging because first-generation progeny tests in Douglas-fir were typically established to measure the relative growth performance of individual trees from open-pollinated parent trees. The overall goal of this dissertation research was to improve growth simulation of genetically improved Douglas-fir...
