As the demands for forest products increase, additional timber harvesting operations can be expected on steep mountainous terrain, The resulting disruption of natural slope stability by man's disturbances (roadbuilding, logging and vegetative manipulation, etc.) may also accelerate mass movement processes in this terrain. Swanston (1969) defines mass movement as ".,...
Commercial thinning young growth forests is an increasingly
important silvicultural technique for improving second growth
management of Douglas-fir stands. Research aimed at advancing the
efficiency of skyline logging operations in small wood timber stands
is essential in order to make thinning these young stands economical.
The purpose of this study...
The preparation of suitable sites for planting and growing of tree seedlings following logging is recognized by British Columbia Forest Service as a major silvicultural problem in the Central and Northern Interior regions of the province. Over the past few decades, scarification trials have been made with various types of...
The purpose of this study was to determine the nature and amountof genetic variation and possible associations between winterhardinessand earliness in winter x spring wheat crosses.Four winter wheat cultivars selected for differences in earlinessand winterhardiness were crossed with a nonhardy, day length insensitivespring wheat cultivar. The following year, experiments containing...
July 1, 1974-June 30, 1976. The first biennial report following the merging of the Wildlife Commission and the Fish Commission. This report summarizes fish and game resources for the biennium, as well as research conducted and an outline of activities to educate the public on operations. It still contains information...
A student report for a Civil Engineering 572 class, this document is an extensive description of the Salmon River estuary, including water flow, quality, predictions for the estuary’s future, and numerous charts and graphs.
Where there’s a law, there is probably someone trying to evade that law. In this document, ODFW personnel working with the Oregon Commission on Fish and Wildlife attempted to tweak crabbing regulations to prevent unfair exploitation of a limited resource. This document addresses the need to sort and discard undersized...
We give a nonstandard method of integrating the equation Bu" + Cu’ + Au = f in Hilbert space by reducing it to a first order system in which the differentiated term corresponds to energy. Semigroup theory gives existence for hyperbolic and for parabolic cases. When C = εA, ε...
