The WBMB's report, submitted early in 1993, recommended the maintenance of a buffer zone around Wood Buffalo to prevent the spread of the diseases to other bison herds and domestic cattle outside the park. It also called for a comprehensive ecological and traditional research program to address knowledge gaps, and a review and selection of the best techniques for screening diseased bison to assess their status. In addition, board members suggested a comprehensive ecological research program--including implications of the Bennett Dam on bison habitat, and potential impacts of bison management on predator/prey relations. It viewed these actions as central to an informed resolution of the bison issue, and the maintenance of the ecological integrity of Wood Buffalo National Park.
