Geography
Country: Canada
State: Alberta
Coordinate: 56.258801° N, -112.690903° W
Latlng basis: stated in text
Geography comments: "The study took place in the Algar sub-range of the East Side Athabasca River (ESAR) caribou range, approximately 70 km southwest of Fort McMurray, Alberta"
Environment
Habitat: boreal forest/taiga
Altered habitat: disturbed forest
Protection: unprotected
Substrate: ground surface
Disturbance: selective logging
Habitat comments: "The 570 km2 area is within the western sedimentary basin of the Canadian boreal forest, and contains vegetation cover broadly typical of this region: lowland habitat of mature black spruce and tamarack wetlands, with upland habitat of aspen, white spruce, and jack pine"
"Anthropogenic features were almost exclusively legacy seismic, with a total of 524 km of seismic lines and a linear feature density of 1.1 km/km2"

Methods
Life forms: carnivores, rodents, ungulates, other small mammals
Sampling methods: no design, automatic cameras
Sample size: 3054 captures or sightings
Years: 2015 - 2018
Nets or traps: 60
Net or trap nights: 43361
Camera type: digital
Cameras paired: no
Basal area status: not applicable
Sampling comments: "We randomly selected line segments ... for camera trap sampling locations, deploying a total of 60 Reconyx HyperFire PC900 camera traps (Reconyx, Holman, WI)"
"Camera trap data were collected between November 2015 and November 2018"
"We set each camera trap on a tree at the edge of a seismic line, facing across the line, at a height of approximately 1 m"
"We set up cameras at least 500 m apart to increase the probability of independent detections; in some cases, line segment proximity resulted in cameras ... being less than 500 m apart (minimum distance 338 m)"
"Cameras were programmed to take one image per trigger, with a one second lag between triggers, no quiet periods, and one daily ‘time-lapse’ image at noon to test camera function and record background conditions"
