The Idiosyncrasies of Streams: Local Variability Mitigates Vulnerability of Trout to Changing Conditions

U.S. Forest Service Pacific Northwest Research Station Science Findings November 2016 Land use and climate change are two key factors with the potential to affect stream conditions and fish habitat. Since the 1950s, Washington and Oregon have required forest practices designed to mitigate the effects of timber harvest on streams and fish. Yet questions remain […]

Flows of the Future: How will climate change affect streamflows in the Pacific Northwest?

U.S. Forest Service Pacific Northwest Research Station Science Findings July 2016 Much of the water supply in the Pacific Northwest originates in national forests. It sustains the region’s aquatic ecosystems, agriculture, hydroelectric power, and community water supplies. Understanding how climate change will affect water supply is one of the most pressing issues of our time. […]

Yet these residents don’t use the roadways; instead they travel in the streams flowing beneath the state’s roadways and bridges. Just as improperly designed roadways result in backups or […]

Using forest knowledge: how silviculture can benefit from ecological knowledge systems about beargrass harvesting sites

U.S. Pacific Northwest Research Station Gen. Tech. Rep. PNW-GTR-912 2015 Sustaining the health, diversity, and productivity of national forests and grasslands is the mission of the U.S. Department of Agriculture (USDA) Forest Service. Yet managing these lands is challenging because people hold different expectations for them. Public uses can include: • Recreation (scenery, trails, bicycle […]

Fingerprints of a forest fungus: Swiss needle cast, carbon isotopes, carbohydrates, and growth in Douglas-fir

U.S. Forest Service Pacific Northwest Research Station Science Findings November 2014 Swiss needle cast is caused by a fungus native to the Pacific Northwest. Its host is Douglas-fir, an iconic evergreen tree in the region. The fungus does not kill its host, but it adversely affects the tree’s growth. Scientists with the Pacific Northwest Research […]
