摘要：

During autumn 1996 and 1997, we surveyed eight inventory blocks covering 6427 km(2) in west-central British Columbia for Mountain Goats (Oreamnos americanus) and estimated that a minimum of 2272 individuals occupied the area. Totals were not adjusted for sightability. For areas above the minimum elevations of goat sightings, the overall population density was 0.70 goats . km(-2). Mountain Goats occurred in groups of 1-33 animals and at elevations ranging from 500 to 2050 m. Most (87.3%) were observed in alpine or cliff areas, but many (10.7%) were observed in timbered areas, especially near the coast. The present Mountain Goat population appears healthy, but expanding forestry operations in Mountain Goat habitat and increased road access will necessitate more refined management in the near future.
