Freshwater Ecosystems

Freshwater Ecosystems

The Arctic contains an abundant and wide range of freshwater ecosystems, including lakes, ponds, rivers and streams and a complex array of wetlands and deltas. This broad range of freshwater ecosystem types contains a multitude of habitats of varying ecological complexity and supports a diversity of permanent and transitory organisms adapted to living in an often highly variable and extreme environment. Moreover, these habitats and species provide important ecological and economic services to northern peoples through the provision of subsistence foods (fish, aquatic birds and mammals), serve as seasonally important transportation corridors (e.g. ice roads), and are ecologically and culturally important habitat for resident and migratory aquatic species.
