Global Range
AC - <100-1000 square km (less than about 40-400 square miles) - ABC - Southern Vancouver Island, Canada historically. Rediscovered in 1998 on nearby San Juan Island, Washington by John Fleckenstein. Based on an extensive survey in 2005 on 16 islands, the subspecies appears to be limited to portions of adjacent San Juan (mainly the southern end) and Lopez Islands in Washington State. If all of both islands is considered range, the extent would be around 500 square miles, but the true range, which would be immediate coastal and prairie portions of these islands, is much smaller.
