Benton County is home to several threatened and endangered species as well as numerous plant and animal species with low or declining populations. The Prairie Conservation Strategy focuses on at-risk species that are prairie dependent or that use prairie, oak savanna, and oak woodland habitats as part of their lifecycle. The HCP Stakeholder Advisory Committee identified a suite of species from the draft USFWS Recovery Plan and the Oregon Conservation Strategy that fit the criteria, as well as several locally rare species. In addition, by conserving a mosaic of habitat types across the landscape, the requirements for numerous additional species can be met.
