Using population dynamic models of moose and brook trout, and assuming topographic, hydrographic and other habitat features typical of the Canadian Shield in Ontario, we have estimated the potential for reduction in population density due to the physical and chemical effects of a deep geologic high-level nuclear waste repository. Preliminary results suggest that the physical habitat effects of repository and community construction, and the increased hunting and fishing pressure in the area, will likely have greater population consequences than the chemical releases from the facility, for most release scenarios. However, a comprehensive evaluation of possible scenarios and their probabilities has not been performed.
