STUDY AREA.4
We conducted aerial surveys for Dall’s sheep (Ovis dalli dalli) in the Liard Range, the Nahanni Range and the Ram Plateau of the Mackenzie Mountains in August 2003 to document sheep distribution and lamb crop. Sheep were classified from the air into four sex/age classes: lambs, yearlings, ewes, and...
