Compton, Peter Zager, and Gregg Servheen AbstractWe monitoredsurvival of 60 woodland caribou (Rangifertarandus) translocatedfrom BritishColumbia to the SelkirkMountains of northernIdaho betweenMarch 1987 and February1992. This translocationwas to assistin recoveryof the endangeredSelkirk population. For all translocatedcaribou combined,estimated annual survivalrates rangedfrom 0.65-0.94 and wereconsistent with declining established populations. No differences(P > 0.10) in survivalwere foundbetween male and femalecaribou or be- tweenmountain and northernecotypes. Causes ofdeath included unknown (n = 14), pre- dation(n = 7), other(n = 4), and human-caused(n = 2), withsummer accounting for the greatestproportion (53o/o). Emigrationof 7 mountainecotype animals also was a loss to the population.
