Common camas (Camassia quamash) is a culturally important wetland plant, used as a staple food source by many indigenous peoples of western North America for thousands of years. Camas populations were once widespread, but conversion of wetland prairies to agriculture has led to declines in suitable habitat. Edible camas bulbs...
Quaking aspen (Populus tremuloides Michx.) is known to be a widely distributed, shade-intolerant and short-lived hardwood found in both seral, even-aged and stable, uneven aged stands. There have been reports of extensive aspen mortality, crown thinning, and branch dieback across North America that have been linked to the occurrence of...
Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...
This dataset contains data layers used and produced by a fuzzy logic model for biomass loss risk under projected climate change in Oregon and Washington west of the Cascade Mountains crest.
The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in...
Locating archaeological sites that predate the arrival of modern sea level has been difficult along the Oregon coast. This is in part believed to be the result of geologic processes that have influenced the preservation, distribution, and visibility of sites within the Oregon coastal landscape. Because of these changes, researchers...
The purpose of this study was to understand the vulnerability and adaptive capacity of shellfish stakeholders in the Pacific Northwest who are adapting to ocean acidification (OA). This study developed a geovisualization tool of existing environmental data for assessing species-specific risk profiles to OA (based on their exposure and sensitivity),...
Artificial radionuclides, induced in water used as a coolant in the Hanford reactors, are discharged into the Pacific Ocean by the Columbia River. Gamma-ray spectrometric measurements show that levels of 65Zn decrease in both sediments and benthic animals with distance from the mouth of the river and with depth of...
Ecological restoration is needed to mitigate losses to biodiversity. Restoration success is enhanced through the use of native plant materials that are genetically diverse and locally adapted. Seed transfer zones have been developed to delineate geographic areas where native seed can be collected and distributed with reduced risk of maladaptation....
