This report summarizes the results from a climate change adaptation workshop focused on the Columbia Plateau landscape in eastern Washington and parts of Idaho and Oregon. The objective of the workshop was to collaborate with landscape managers to apply results from the Pacific Northwest climate change vulnerability assessment (PNWCCVA) to on-the-ground ecological management objectives. Specifically, we sought to address the following questions: How can model results and datasets be applied to assist with management decisions? How can model results and datasets be made more useful for informing species and landscape management?To this end, we presented information and data developed as part of the PNWCCVA to workshop...
Climate change is anticipated to increase the frequency and intensity of droughts, with major impacts to ecosystems globally. Broad-scale assessments of vegetation responses to drought are needed to anticipate, manage, and potentially mitigate climate-change effects on ecosystems. We quantified the drought sensitivity of vegetation in the Pacific Northwest, USA, as the percent reduction in vegetation greenness under droughts relative to baseline moisture conditions. At a regional scale, shrub-steppe ecosystems—with drier climates and lower biomass—showed greater drought sensitivity than conifer forests. However, variability in drought sensitivity was considerable within biomes and within ecosystems and was mediated...

PIONEER MOUNTAINS ― CRATERS OF THE MOON CLIMATE CHANGE ADAPTATION WORKSHOP REPORT Prepared for the Great Northern Landscape Conservation Cooperative by: John C. Withey, Julia L. Michalak, Joshua J.

Abstract (from Wiley Online Library): As evidenced by past climatic refugia, locations projected to harbor remnants of present‐day climates may serve as critical refugia for current biodiversity in the face of modern climate change. We mapped potential climatic refugia in the future across North America, defined as locations with increasingly rare climatic conditions. We identified these locations by tracking projected changes in the size and distribution of climate analogs over time. We used biologically derived thresholds to define analogs and tested the impacts of dispersal limitation with 4 distances to limit analog searches. We identified at most 12% of North America as potential climatic refugia. Refugia extent...
