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

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"
