Accompanied by Newfound- land and Labrador biologist Stu Luttich, CWS tech- nician John Maxwell, pathologist Eric Broughton, and health inspector Dale Duplessis of Agriculture Canada, Parker travelled to Nain, Labrador. There the team participated in a community Caribou hunt and examined Caribou shot by local hunters. The information they gathered proved to be of particular interest to the Caribou management biolo- gists of Quebec and Newfoundland and Labrador. It was also relevant to the mandate of a scientific review committee struck to assess the impact of low- level military flight training over an area of Labrador Notes 1.
