    Current Sponsored Projects

    • Climate Change Applications and Implementation in National Forests
      This project partnership will allow the PNW Station to (1) provide timely CCVAs, adaptation plans, and other products to USFS Regions in the western U.S., (2) assist USFS units with implementation of climate-informed land management plans, environmental assessments, programs, and project plans; (3) enhance the relationship with UW, and (4) maintain national leadership in climate change research.
    • Climate Applications and Implementation in National Forests
      In this project, we will develop science-management partnerships that will (1) provide information on climate change and drought, (2) assess the effects on forest and rangeland ecosystems, and (3) develop management responses that can be implemented to reduce negative effects.
    • Climate Change Applications in National Forests
      In this project, we will develop science-management partnerships that will (1) provide education on climatic variability and change, (2) compile vulnerability assessments for multiple resources (vegetation, water, wildlife, fish, etc.), (3) develop adaptation strategies and tactics that can be implemented to reduce negative effects, and (4) assist with incorporation of climate-smart principles in resource management and planning.
    • The Western Mountain Initiative: Vulnerability and Adaptation to Climate Change in Western mountain Ecosystems
      We will address the extent to which climate drivers are mediated by regional- or watershed-scale controls on ecosystem processes, thus quantifying vulnerability to climate change in mountain ecosystems. Region-specific results and emergent West-wide patterns will be shared with resource managers through workshops and a comprehensive web-based toolkit on climate-change science and adaptation management.
