This report provides the details of the construction and application of a set of population and harvest models for boreal caribou in two Wildlife Management Zones and six other areas of interest in the NWT. The objective of the modelling is to provide perspective on likely relationships between hunter harvest levels and NWT caribou population growth rates. The basic vital rates on which the models depend are derived from recent field studies conducted by GNWT-ENR in each of the geographic areas of interest. The population models revealed limits on harvest levels that would increase the probability of caribou in each area being able to sustain themselves or grow over time.
