During each visit 1 looked for Wolves and their sign on hiking trails, river banks and meadows. Known Wolf denning and rendezvous areas were checked for evidence of use. At occupied sites I observed adult Wolves and pups through binoculars or a 20x telescope, noting details of their pelage and taking care not to cause undue disturbance. At Devona I used simulated Wolf howls to try to attract Wolves on meadows and riverflats below a lookout hill (Dekker 1985a). I camped on the same sites, using a pup tent during summer, and a larger tent with wood stove during winter. Summer trips were usually made alone, winter trips with a companion. Information on Wolf sightings in and near the study area was also obtained from district wardens and from trappers on adjacent provincial lands. Estimates of Wolf numbers in the entire park were solicited from Parks Canada and the Warden's Office. Results Wolf numbers During the period 1965-1968 I found Wolf tracks to be common at Willow Creek in all seasons. The District Warden saw a pack of eight Wolves in 1965. One day later, six Wolves were found dead near a poison bait on Rock Lake. Between 1969 and 1972 there was no evidence that more than one pack, 10-12 animals, occurred in the study area. They ranged from Snaring to Moosehorn, and from Devona to Rock Lake and Mowitch Creek (Carbyn 1973). The pack denned at Willow Creek where two dens were used intermittently from 1969 to 1981. In 1977, this pack had grown to 16 animals. After 1973, a Wolf pack denned at Devona in the lower Snake Indian Valley. The pack contained at least 11 and probably 14 members in the late 1970s, bringing the total Wolf population of the valley to 30 anima
