more than 100 species of trees, shrubs, herbs, and ferns.
What is it?
Swiss needle cast of Douglas fir is a foliage disease caused
by the fungus Phaeocryptopus gaeumannii. The disease is
specific to Douglas-fir, affecting no other tree species.
Alerts people who visit, live, or work in certain areas of Oregon and California about a serious plant disease called Sudden Oak Death, and asks them to take steps to prevent spreading the disease. Gives action steps, shows disease symptoms on various host plants, and gives numerous sources for more...

Publication examines the wide variety of insect pests, diseases and environmental conditions that can affect Sitka Spruce along the coastline of Oregon.
Shore pine is a subspecies of lodgepole pine that inhabits the coastal strip in Oregon. Insect pests, diseases, and nonbiological (abiotic) factors may have an impact on growth, visual appearance, and productivity of trees. In this publication, we review the general nature of shore pine in Oregon and the common...
Discusses options for managing major insect pests and diseases of conifers in Oregon forests: bark beetles, wood borers, and ambrosia beetles; defoliators; aphids, adelgids, and scale insects; terminal and branch insects and pitch moths; root diseases; stem decays; foliage diseases; canker diseases and canker-causing rust diseases; and mistletoes.

Proteases present in shrimp processing waste are factors in the
technology of shrimp. The distribution of proteolytic activity in
shrimp parts was determined using hemoglobin and casein as substrates. The effects of various parameters upon activity of proteases
in the inedible portion were determined using muscle protein as a
substrate....
Descriptions and distributions are given of 28 species of

This research consists of two related yet distinct
studies: an observational study of the surface character of
the penetration of marine air into the southern Willamette
Valley and a climatological study of the summertime air
masses of northwestern Oregon.
For the observational study, temperature and estimated
wind data were gathered...
