Freshwater wetlands in Costa Rica are seasonal or permanent areas where water saturates the soil, creating rich, biodiverse environments that support a wide range of aquatic and semi-aquatic life. These habitats include swamps, marshes, floodplains, and shallow lakes. They act as natural water filters, buffers for flood control, and essential breeding grounds for birds, amphibians, fish, and insects. Many wetlands are internationally recognized under the Ramsar Convention for their global ecological value.

Freshwater wetlands are among the most productive ecosystems in Costa Rica and essential for the survival of migratory birds. Many serve as buffer zones that mitigate flood impacts and support community livelihoods through eco-tourism and fisheries.
