The salt marshes of the Manicouagan – Uapishka reserve are among the most productive habitats on the planet, acting as important resting places for more than 200 migratory birds. Fauna characteristic of boreal forests in the area include the vulnerable boreal woodland caribou (Rangifer tarandus caribou), least weasel (Mustela nivalis), short-eared owl (Asio flammeus), golden eagle (Aquila chrysaetos), and the threatened wolverine (Gulo gulo) and beluga whale (Delphinapterus leucas).
