Geography comments: "northeast of Lac La Biche... The study area included the area around Christina Lake and Winefred Lake, north of the Cold Lake Air Weapons Range, and is approximately 3000 km2"
Habitat: boreal forest/taiga
Protection: unprotected
Substrate: ground surface
Disturbance: selective logging
Habitat comments: "boreal forest... Anthropogenic disturbance is extensive with forestry and energy sector activities, including roads distributed over the study area"
Life forms: carnivores, rodents, ungulates, other small mammals
Sampling methods: no design, automatic cameras
Sample size: 134482
Years: 2011 - 2014
Seasons: winter, spring, summer, autumn
Nets or traps: 61
Net or trap nights: 60937
Camera type: digital
Cameras paired: no
Trap spacing: 2.000
Sampling comments: "Mammal frequency of occurrence was sampled at 61 camera trap sites (Fig. 1). Reconyx PC900 HyperfireTM infra-red remote digital cameras (Holmen, WI, USA) were deployed for three years: October 2011–October 2014... the camera traps were distributed across the landscape by using a constrained random stratified design intended to equalize representation of all habitat types... We imposed a minimum 2-km distance between cameras... The camera trap survey had a total sampling effort of 60, 937 camera trap-days"
