Populations of woodland (boreal) caribou are in decline in many areas of Canada's boreal region . Cortex worked with Environment Canada and a team of Science advisers to develop methods for identifying critical habitat and population recovery options for this wide-ranging species. Cortex developed population models, and habitat dynamics models for assessing population trend, habitat condition and the risks that populations would not become self-sustaining over the next 25 years, given a range of uncertainties in the data. In combination with other researchers, the results were used to develop risk curves for determining possible demographic consequences of different levels of disturbance in critical habitats. The results helped inform Environment Canada's Recovery Strategy for Woodland Caribou (Boreal Population), released in 2013.
