Two New Calif DU Projects

Delevan National Wildlife Refuge, Tract 44, Cell 3 Restoration Project, Colusa County

The project site is owned and operated by the U.S. Fish and Wildlife Service as part of the Delevan National Wildlife Refuge. The goal of this project is to restore approximately 40 acres of fallow land to native grass and forbs. This tract is currently infested with invasive, exotic weeds and is located between managed wetlands and private rice fields. Project work will include burning of the existing thatch layer, disking the seed bed, application of herbicides and seeding and plugging the native grasses and forbs. Restoration will provide nesting cover for waterfowl and other ground nesting birds.

Dry Creek Riparian Enhancement, American and Sutter Basins Wetlands NAWCA, Sacramento and Placer Counties

The project area consists of a 149-acre riparian corridor along Dry Creek and several of its tributaries, extending from the Natomas Main Drain northeast past Roseville to near Folsom Lake. The project area includes both publicly-and privately-owned lands. Public lands fall under the ownership of a variety of local governments including Sacramento and Placer Counties and the cities of Sacramento , Roseville , and Rocklin. Public uses consist primarily of fishing and other wildlife-oriented recreation such as bird watching, photography, and nature study. Riparian management activities that are routinely conducted on both public and private lands include chemical treatment and hand removal of invasive vegetation and planting of additional native riparian vegetation.

Project work consists of removing invasive vegetation by chemical treatment and hand pulling. The riparian corridor along Dry Creek and its major tributaries became badly infested with invasive weeds, displacing displaced native riparian vegetation, limiting public access, increasing erosion, affecting flow patterns, and greatly reducing the quality of habitat for riparian birds and other wildlife.

Riparian habitat has been reduced to less than 5% of its historic range in California . The riparian habitat that remains along Dry Creek and its tributaries provides critical habitat for numerous wildlife species, including many special status species.
