Beluga whale summer herds distribution in the St. Lawrence Estuary

This layer represents the seasonal distribution of the St. Lawrence Estuary beluga whale population (Delphinapterus leucas). Three groups are represented: females with calf, adult males and mixed sectors. Herd distribution was defined using Fisheries and Oceans Canada (DFO) published data about beluga whales (see references).

Herd distribution areas are only valid during the summer, and the uses of these areas by the herds are unknown.
