Habitat comments: "The canyon was characterized by steep sagebrush (Artemisia tridentata) canyons and open hillsides"

Methods
Life forms: carnivores,ungulates

Sampling methods: line transect,automatic cameras

Sample size: 51416 captures or sightings

Years: 2008 - 2011

Days: 729

Seasons: winter,spring,autumn

Nets or traps: 7

Camera type: digital

Cameras paired: yes

Trap spacing: 3.5

Sampling comments: "We installed 3 digital infrared Reconyx® (Holmen, WI) cameras in each of the 7 underpasses, including one at the entrance, one in the middle, and one at the exit... Underpasses were equipped with cameras from 1 October through 31 May for 3 years. The study period encompassed autumn migration (2008, 2009, and 2010), winter use, and spring migration (2009, 2010, and 2011)"
the study therefore spanned 243 days/season times 3 years = 729 days
spacing was 21 km/6 traps from the start = 3.5 km
