This report by Gunn et al. describes variations in the location, size and shape of the Bathurst calving grounds, describes the patterns and predictability of caribou occupation of their calving grounds, and recommends how to use the currently available monitoring data to establish calving ground boundaries that reflect the probability of the location and occupation of their calving grounds.
This report by W. Rettie addresses two complementary uses of radio-colars to monitor dynamics in barren-ground caribou populations in the Northwest Territories.
This DRAFT report by Nishi et al. discusses the use of the calving ground photographic survey technique to estimate abundance and distribution of breeding females in the Bathurst herd of barren-ground caribou in June 2009.
This DRAFT report by Nagy and Johnson reports the results of four annual post-calving classification surveys completed for the BluenoseWest herd during 2002 to 2005 and the results of analyses completed to map the distribution of cows and calves on the calving grounds.
