Main points:

  • Habitat edges most used
  • Open grassland habitats used less if far

from cover

  • Moorland used little (in winter)
  • Range size varies with sex, season and

prey availability, usually >2km2

  • Den locations match general habitat

use except less often in open habitat

  • Dens can be in many different

structures
