Projected changes in climate and hydrology will have far-reaching effects on aquatic and terrestrial ecosystems, especially as frequency of extreme climate events (drought) and associated effects on ecological disturbance (wildfire, insect outbreaks) increase. Decreased snowpack and earlier snowmelt will shift the timing and magnitude of streamflow peak flows will be higher, and summer low flows will be lower. The vulnerability assessment indicated that effects of climate change on hydrology in the Blue Mountains will be especially significant. The vulnerability assessment emphasized four resource areas-water, fish, upland vegetation, and special habitats-regarded as the most important resources for local ecosystems and communities. These organizations worked together over a 2-year period to conduct a state-of-the-science climate change vulnerability assessment and develop adaptation options for national forests in the Blue Mountains region. Department of Agriculture, Forest Service, the University of Washington, and the Climate Impacts Research Consortium at Oregon State University. ![]() Partnering organizations included three national forests (Malheur, Umatilla, Wallowa-Whitman National Forests), the Pacific Northwest Research Station and Pacific Northwest Region of the U.S. The Blue Mountains Adaptation Partnership was developed to identify climate change issues relevant to resource management in the Blue Mountains region, to find solutions that can minimize negative effects of climate change, and to facilitate transition of diverse ecosystems to a warmer climate. ![]()
