The Peace/Williston Fish and Wildlife Compensation Program (PWFWCP) has conducted many winter inventories of high-elevation mountain ranges throughout the Williston Reservoir watershed in north-central British Columbia. The inventory objectives have been to obtain population and distribution data on woodland caribou (Rangifer tarandus caribou), Stone's sheep (Ovis dalli stonei), and mountain goats (Oreamnos americanus). Information on the distribution and abundance of woodland caribou in the Williston Reservoir watershed was fragmentary up until the mid-1990's. Recent studies and inventories have identified the distribution and numbers of several herds and/or winter ranges throughout the watershed (Murray 1992; Wood 1994, 1995a,b, 1996, 1998; Wood and Hengeveld 1998b; Backmeyer and Wood, in prep.). The Williston Reservoir watershed supports about 10% (1100) of the world's Stone's sheep, including about 160 animals in the Peace Arm region (Davidson and Dawson 1990). The majority of these sheep are found on the north side of the Peace Arm, between Butler Ridge and the Nabesche River (Davidson and Dawson 1990). Only a few sheep exist south of the Peace Arm. In the late 1970's, roughly 20 sheep were observed at Mt. Selwyn (J. Elliott, BC Environment, Fort St. John, personal communication); reports of approximately 15 sheep were noted in the 1980's (D. King, BC Environment, Prince George, personal communication). During a 1991 inventory of wildlife wintering on mountain ranges south of the Peace Arm, only 11 Stone's sheep were located: 7 on Mt. Selwyn and 4 further east on Mt. Monteith (Backmeyer 1991), the latter of which were transplanted to the area one year earlier by the PWFWCP. There are an estimated 2000 mountain goats distributed throughout the Williston Reservoir watershed (Davidson and Dawson 1990). Most goats residing in the Peace Arm region winter on south or west-facing wind blown slopes on steep, rocky terrain. Backmeyer (1991 ...
