Non-linear nitrogen dynamics and calcium depletion along a temperate forest soil nitrogen gradient

Creator:: Sinkhorn, Emily R.
Abstract:: Understanding how N availability influences base cation stores is critical for long-term ecosystem sustainability. Indices of nitrogen (N) availability and the distribution of nutrients in plant biomass, soil, and soil water were examined across ten young, unpolluted Douglas-fir (Pseudotsuga menziesii) stands in the Oregon Coast Range spanning a three-fold soil...

Genetic differences in red alder populations along an elevational transect

Creator:: Campbell, Allan, 1936-, Ching, Kim K., and Oregon State University. Forest Research Laboratory
Abstract:: "Because forest managers and geneticists need basic information about natural variations in populations of red alder, we studied conelet and seed characteristics, as well as early growth, of this species along an elevational transect in the Coast Range of Oregon."--P. [1].

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...

Influence of soil and rhizosphere actinomycetes on Frankia infection and nitrogenase activity in Alnus rubra Bong

Creator:: Rojas-Melo, Nestor S.
Abstract:: Nodulated roots of young red alder trees and soil samples were collected from a 5 year old clearcut on Mary's Peak, Oregon. Frankia was isolated from root nodules, andactinomycetes from nodules, roots, and soil. A total of 229 pure culture actinomycete isolates were recovered: 131 colonies from root surfaces, 52...

Seasonal and diurnal trends of leaf water potential and stomatal conductance of red alder (Alnus rubra Bong) growing along a density gradient in western Oregon

Creator:: Lu, Shengjun
Abstract:: Three Nelder plots of 3-year-old red alder (Alnus rubra Bong) were used for this study at the Cascade Head Experimental Forest, Oregon in the growing season of 1988 at an elevation of 330 meters. Each Nelder plot represented a range of densities from 238 to 101,219 trees per hectare. The...

Marketing alder and other hardwoods

Creator:: Cleaves, David A., 1948- and Oregon State University. Extension Service
Abstract:: Many landowners have hardwood trees that appear to be of marketable size. Some of these landowners may want to replace the hardwoods with conifers immediately.

Density management guide for red alder

Creator:: Puettmann, Klaus J., DeBell, Dean S., Hibbs, David E., and Oregon State University. Forest Research Laboratory
Abstract:: Our diagram is intended to provide general guidance in density management of red alder. The management zone defines a reasonable compromise between individual-tree and stand growth and mortality. Factors considered in its formation include desired tree size at harvest, growth rate, and yield per acre. Social and legal constraints, as...
