Table 2: Spatially-explicit capture-recapture density estimates for boreal caribou in Alberta, Canada. Density estimates (D) are per 1000 km², CV(D) is the coefficient of variation (SE of density estimate/density estimate), g0 indicates the capture probability at the home range centre, sigma is the spatial scale parameter in metres, home range estimates are in km², and N is the abundance over the study area.
