Bill Mair recruited George Scotter from the Range Science Department at Utah State University to study this possibility. Scotter examined winter ranges in northwestern Manitoba, northern Saskatchewan, and the Northwest Territories,^^ initi- ating research that was continued in later years by Donald (Don) Miller and Donald C. (Don) Thomas. Further Caribou work included a detailed analysis of nutritional requirements, carried out by Eoin McEwan under the joint sponsorship of CWS and the University of British Columbia. It was not until 1966, however, that another extended field study of Barren-ground Caribou got under way. This time, the target was the Kaminuriak herd, a large group that wintered in northern Manitoba. Like the Beverly herd to the west, this group had also declined in size, dropping from about 125 000 in the late 1940s to between 30 000 and 70 000 a decade later.^^ Now, however, current information from provincial and territorial game officers as well as annual kill esti- mates from the RCMP were raising hopes that the population trend might have halted or even turned around. Andrew Macpherson was named to head the study. The researchers included T. Charles (Chuck) Dauphine, who was to assess the condition and reproductive success of the animals; Don Miller, who would conduct winter range studies; Frank L. Miller, whose study focused on the age structure of the herd; and Gerry Parker, who would track season- al distribution and migration. Gaston Tessier, senior technician and laboratory manager for the Eastern Region, was also attached to the team. The co
