• Two types of wolves:
    1. migratory (North Slope)
    2. territorial (Porcupine River and mountains south of treeline)
  • Normal low density for Arctic wolves
  • Wolf numbers stable (1987-93)
  • Number of packs double where caribou winter (Northern Richardsons)
  • Wolf numbers limited by:
    1. Low reproduction due to:
          -prey availability at dens
          -disease (Brucellosis?)
    2. Average natural mortality on adults
    3. Low hunter harvest of wolves in most years (except 1992)
