This DRAFT report by John Nagy provides a description of how the retrospective analyses of the 1986, 1987, and 1992 photocensus survey data were done to derive population estimates of the Cape Bathurst, Bluenose-West & East herds, the methods used to generate population estimates of the herds during 1986, 1987, 1992, 2000, 2005, and 2006, and an evaluation of the fidelity of cows and bulls to post-calving/early summer ranges.

This DRAFT report by John Nagy provides evidence that the Cape Bathurst, Bluenose-West and Bluenose-East calving grounds are not theoretical and justification for the division of the "Bluenose" herd. 

These are the figures associated with the Johnson et al. report posted on the registry.

This DRAFT report by Johnson et al. reports the results of three systematic transect surveys of the Ahiak calving ground conducted June 2006, June 2007, and June 2008.  Figures from this report will be posted separately.

This unpublished report by Heard and Williams discusses how GNWT research programs have contributed to the understanding of the ecological processes in the lichen-caribou-wolf ecosystem.

This unpublished report by Heard & Williams reviews caribou research done out of Yellowknife, specifically caribou composition and census surveys. 

This DRAFT report by Anne Gunn which details measure of calf-cow ratios and reports on environmental conditions on the summer range, which may contribute to calf survival rates.

This report by Gunn et al. compiles information about the collaring program and chronology of collaring.  Satellite-collared caribou locations have been used to describe season and annual movements.

This DRAFT report by Boulanger et al. analyzes new methods of the MARK program to compare survival rate estimates in four herds of barren-ground caribou and to determine if there are seasonal differences or temporal trends in survival rates. 

This is a draft report provided to the WRRB to assist the Board in considering a possible Total Allowable Harvest for the Bathurst herd. The analyses within the report could also be used to help define a technically sound monitoring approach and to contribute to an adaptive management program.
