Abstract: Time-lapse cameras were utilized, evaluated, and shown to be effective for gathering limited distribution and population data on grizzly bears (Ursus arctos) and black bears (U. americanus). Thirty-six camera sites using 5 different lures were monitored for 551 camera-days. Thirty-one bears (5 grizzly, 25 black, 1 unknown) were identified at 15 stations. Young:adult and young:female ratios were 0.4 and 1.5 for black bears, and 0.7 and 2.0 for grizzly bears, respectively.
