Assessing threats to Cascade red foxes in Washington

March 2022 - September 2025


Participating Agencies

  • Washington Department of Fish and Wildlife
  • USGS

The Cascade red fox (CRF) is one of the rarest and most genetically distinct carnivores in North America. Today, CRF appear to be absent from the North Cascades and are found primarily in Washington’s South Cascades including Mount Rainier National Park (MORA) and surrounding wilderness. A lack of information about threats to CRF, and the lack of a process for identifying and evaluating potential conservation actions, is complicating efforts to conserve this state-endangerd species. In this collaborative effort with partners including the National Park Service and Washington Department of Fish and Wildlife, we are combining existing data and new radio-tracking data to understand effects of threats on fox movements and demography. Based on results, we will engage partners in a decision-making process to identify and evaluate management actions. This work will inform ongoing conservation of CRF throughout their range in Washington, including development of a recovery plan for CRF in Washington.
