If reintroductions are warranted, use individuals from nearby sites and consult results of feasibility studies. The Cascades frog Rana cascadae belongs to the Amerana (or Rana boylii) group that includes. Use prescribed burning or hand-felling of trees periodically to manage plant succession. Carefully manage livestock grazing in occupied wet meadows. Monitor and address impacts of fish stocking and poor water quality. Explore the feasibility of reintroduction at historically occupied sites. Evaluate the effects of pathogens and airborne environmental pollution on this species. Identify habitat characteristics that could enhance migration and gene flow. Investigate habitat requirements and how they vary by elevation across the species' range. Water availability (changes in snow pack/melt), sedimentation (livestock grazing/watering), and predation and competition by introduced fish are additional threats. Cascades frogs are potentially sensitive to waterborne pathogens. It has experienced substantial reductions in the southern parts of its range, particularly in California.
