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"

Methods
Life forms: carnivores,rodents,ungulates,other small mammals

Sampling methods: no design,automatic cameras

Sample size: 134482 captures or sightings

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

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"
