About the Complex

GBH - Michael Hersen_512x219

A once wild and dynamic Columbia River scoured the earth and spread rich soils along its edges and into its floodplain. Left behind was a mosaic of wetlands, riparian forests, sloughs, wet meadows, and meadows, which sustained a diversity of plants, animals, and fish. In turn, humans have thrived on the River's abundance for thousands of years. Today, these habitats and wildlife resources are protected along the lower Columbia River within the boundaries of the Pierce, Franz Lake, Steigerwald Lake, and Ridgefield National Wildlife Refuges.

  • Why a Complex

    Refuges are grouped into a complex structure because they occur in a similar ecological region, such as a watershed or specific habitat type, and have a related purpose and management needs. Typically, a project leader or complex manager oversees the general management of all sites with the support of a staff that are centrally located and support all refuges within the complex.

  • Ridgefield National Wildlife Refuge
