Ecoregions
Strategy Habitats

Coastal Dunes
Occurring along the Oregon coastline, coastal dunes provide habitat for species that prefer open, sandy habitats with a high degree of disturbance from winds and tides.

Estuaries
Estuaries occur where freshwater rivers meet the oceanic salty waters, are influenced by tidal flooding, and experience frequent periodic changes in salinity, water levels, sunlight, and oxygen.

Flowing Water and Riparian Habitats
Flowing Water and Riparian Habitats include all naturally occurring flowing freshwater streams and rivers throughout Oregon as well as the adjacent riparian habitat.

Wetlands
Wetlands are covered with water during all or part of the year. Permanently wet habitats include backwater sloughs, oxbow lakes, and marshes, while seasonally wet habitats include seasonal ponds, vernal pools, and wet prairies.
