Since emigrating to Canada from his native Holland, wildlife biologist Dick Dekker has spent much of his life in the Canadian Northwest - among lakes and rivers, forest and mountains - observing wildlife from a tent or remote cabin. His many publications on the subject range from technical papers to popular books, including Wolves of the Rocky Mountains--From Jasper to Yellowstone and Two decades of wildlife investigations at Devona, Jasper National Park, 1981-2001.
