Canada's wilderness areas harbour some of the last remaining species of North American wildlife. This film shows what is being done by specialists of the Canadian Wildlife Service to prevent further depletion of their numbers. It is an enormous program of tabulating, banding, tagging, and, in the case of larger animals such as the bear and the buffalo, giving health check-ups. An engrossing film for any audience, replete with close-ups of animals, waterfowl, and fish.
