HEAT (Habitat/Ecosystem Assessment Tool): Transforming and improving HAAT, an existing tool, for use in evaluating multiple stressors


Images of the habitat variables assessed by the Habitat/Ecosystem Assessment Tool: water temperature is illustrated in the centre by a graph of lake temperature structure.

The Habitat Alteration Assessment Tool (HAAT) has been used to determine habitat supply in freshwater areas based on fish communities and their habitat needs. HAAT uses data on depth, substrate, and vegetation to evaluate ecosystem changes and impacts on fish habitat. This project will revise HAAT to include more variables, such as temperature, and consider water level fluctuations, which are affected by climate change. The resulting science-based management tool, known as the Habitat/Ecosystem Assessment Tool (HEAT), will be accompanied by guides and training materials once software development is complete. End-users are those who develop, change, or restore aquatic environments or who evaluate or assess those changes.
