The U.S. Forest Service is currently working with multiple agencies and organizations to detect fisher (Martes pennanti) in the Rocky Mountains. Objectives are to:

  • Delineate the geographic range of fisher in the Rocky Mountains by detecting all populations and determining these populations' boundaries,
  • Determine which Rocky Mountain fisher populations have native genes and which fisher populations are comprised of reintroduced individuals, and
  • Index the abundance of fisher (e.g., minimum number of individuals alive) in each population through the use of DNA.

To meet these goals, Rocky Mountain Research Station scientists and their partners established this survey protocol.
