During 3 field seasons, from 1996 to 1998, we studied the distribution, life history, and habitat use of the sharp-tailed snake on the southern Gulf Islands and southeastern Vancouver Island (Engelstoft and Ovaska 1997, 1998, 1999). Here, we present a summary and preliminary results of the study with emphasis on natural history of populations at 2 recapture sites on the Gulf Islands: near Magic Lake, North Pender Island (0.75 ha, 48°46’N, 123°18’W), and near Vesuvius, Saltspring Island (0.15 ha, 48°54’N, 123°35’W). Many aspects of the life history of the sharp-tailed snake, including the age at sexual maturity, timing of mating and oviposition, and frequency of reproduction by females, remain unknown. Seasonal movements and habitat use patterns also require further study. Filling these data gaps is important for management and for the protection of adequate habitats to ensure the persistence of the species in British Columbia.
