Résumé :	Lagopus leucurus saxatilis, a subspecies of White-tailed Ptarmigan endemic to Vancouver Island, is listed as vulnerable by the British Columbia Conservation Data Centre, but little is known about its population status or trends. The only previous journal paper concerning this subspecies was published in 1939. Data on distribution, gathered using historical records and public survey (166 records) in combination with our field studies, indicated that this ptarmigan Subspecies currently inhabits most, if not all, available habitat on Vancouver Island, and the range has not contracted over the past 25 yr.
