This report provides rockfish landings (weight in metric tons) based upon species composition samples taken from commercial trawl landings in Oregon. Rockfish (Family Scorpaenidae) are an important segment of Oregon trawl landings. For over 30 years, the Oregon Department of Fish and Wildlife (ODFW), Marine Finfish Program, previously known as...
In the late 1970s, approximately 400 miles of streams were inventoried by the
Prineville District of the Bureau of Land Management for in-stream and riparian condition.
During the summer of 1994, the riparian portion of the survey was repeated on 17 of the
original streams miles, contained within 11 stream...
The OSU Extension Soil Sensitivity Database lists
nonirrigated and irrigated soil sensitivity ratings for every
map unit of every soil survey in Oregon. These ratings
were developed for the Oregon Water Quality Decision
Aid, a tool for evaluating groundwater vulnerability to
pesticide contamination.
The study of reptiles and amphibians is called herpetology. The word “herps” comes from the same root word. Herps in your landscape are fun to watch, interesting to learn about, and a benefit to your local ecology. You can attract them by adapting your yard to their habitat needs.
Streamflow forecasts are essential to the optimal operation of
hydroelectric and irrigation reservoirs in the Pacific Northwest.
Satellite snow cover observations would aid in these streamflow forecasts
by providing snow cover data at regular time intervals. Unfortunately,
satellite capability to remotely sense mountain snow cover
conditions is indeterminate due to...
Relations between the diversity of juvenile anadromous salmonids and pool features
were examined in a managed and a pristine watershed in Oregon during the summer of
1990. There were no differences (p>0.05) in pool depth, velocity or pool wood volumes
between streams. However, the pristine system had twice the number...
