Discusses recent trends in hunger and food insecurity in Oregon and the Northwest. Compares data for metro and nonmetro areas, and looks at the affect of employment type on rates of food insecurity.
With a little extra planning and care, you can enjoy fresh vegetables from your garden most of the year. Many cool-season crops produce well in the fall and, in mild-winter areas of the Pacific Northwest, hold through the winter if protected. You can plant these vegetables in mid- to late...

A stalagmite (sample OCNM8-02A) collected from Oregon Caves National Monument (OCNM) was sampled for stable isotope ratios in order to develop a record of Pacific Northwest climate history. Nine U-series dates indicate that the record spans the time period - 13.5 - 9.5 ka. The stalagmite growth rate varied from...

A study of precipitation and yield levels in fallow-wheat rotations at three
Pacific Northwest locations demonstrated that in the Columbia Plateau region,
the variability and skewness of precipitation increased with decreasing mean
amounts of precipitation. The seasonal distribution of precipitation had a
marked effect on wheat yield. Comparisons of precipitation...
Bats represent the second most diverse group of mammals inhabiting the western slopes of the Cascade Range in southern Washington and Oregon Coast Range. Bat populations may well be sensitive to changes in forest age, structure, or distribution, but their nocturnal habits and high mobility render the study of the...
