Estuaire-des-Rivières-Koktac-et-Nauberakvik

PROPOSED BIODIVERSITY RESERVE

1,323 km² | Designated in 2009

The Estuaire-des-Rivières-Koktac-et-Nauberakvik proposed biodiversity reserve (Réserve de biodiversité projetée de l’Estuaire-des-Rivières-Koktac-et-Nauberakvik) protects a territory composed of numerous lakes and rivers as well as its estuary on the coastal section. It protects species that are important to the traditional activities of the surrounding communities, including those related to fishing. It also protects part of the range of the Leaf River migratory caribou herd.

In addition, this territory protects a particular geomorphology made up of low hills with little variation in elevation that are covered with a relatively thick layer of glacial deposits, i.e., loose materials accumulated by a glacier or directly influenced by the presence of a glacier. A small portion of the area also has a distinctive drumlinoid deposit, which consists of large tapered formations that indicate the direction of ice flow.
