The area includes much of the Necanicum River. The watershed provides critical habitat for many coastal plant and animal communities. Floodplains and associated wetland and riparian ecosystems provide important flood protection for downstream communities and act as corridors allowing wildlife to move along and between habitat areas. Management of the area promotes the connectivity and corridor through the landscape.

Coast Range

Oregon’s Coast Range, known for its dramatic scenery, is extremely diverse, with habitats ranging from open sandy dunes to lush forests and from tidepools to headwater streams. It follows the coastline and extends east through coastal forest to the border of the Willamette Valley and Klamath Mountains ecoregions

Strategy Habitats

Oregon Coastal Dunes

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.

Estuary Strategy Habitat, Siletz Bay

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.

Grassland Strategy Habitat

Grasslands

Grasslands include a variety of upland grass-dominated habitats, such as upland prairies, coastal bluffs, and montane grasslands.

Coast Range Ecoregion

Late Successional Mixed Conifer Forests

Late successional mixed conifer forests provide a multi-layered tree canopy, including large-diameter trees, shade-tolerant tree species in the understory, and a high volume of dead wood, such as snags and logs.

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.
