The objectives of this study are to: 1) study the variations
among stands of old-growth Sitka spruce forest located within a relatively
restricted geographical area, 2) determine the relationship between
species distribution, vegetational pattern, and such site factors
as slope and aspect, and 3) ascertain the abruptness of phytosociological
change...

A survey was made of the discolorations occurring in Sitka spruce wood, and toughness tests were made on specimens that included discolorations of unknown or doubtful significance.
Western hemlock-Sitka spruce forests, where prior precommercial thinning has occurred, constitute one of the most productive
young-growth management types along the Pacific Coast from Oregon to southeast Alaska. These stands are ready for a first commercial thinning entry, however, the costs and benefits of such entries and resulting impacts at...
Western hemlock and Sitka spruce are relatively thin-
barked species and susceptible to damage during thinning
operations. Damage to the wood allows decay-causing fungi
to enter resulting in loss of merchantable volume at the
time of final harvest. Cable yarding systems are needed for
much of the thinning because most...
Publication examines the wide variety of insect pests, diseases and environmental conditions that can affect Sitka Spruce along the coastline of Oregon.
