Solano County Habitat Restoration Partnership
Project Purpose

In partnership with Solano Resource Conservation District (SRCD), Dixon Resource Conservation District, Reclamation Districts 2068, 2098, and 501, landowners, and community volunteers, over 60 miles of levees and canals have had non-native invasive plants, arundo, and red sesbania either eradicated or heavily controlled. In addition, an installed cattle exclusion fence will prevent grazing cattle to enter the toe drain of Hastings Cut or Hastings Cut itself, improving water quality and waterside vegetation. Drainage ditches located near Lindsey and Haas Sloughs will be graded and planted with native grasses and plants to improve water quality, soil structure, and to provide habitat for insects and wildlife. An irrigation canal has been graded and planted with native grasses and plants to stabilize the soil, and provide increased habitat. It is hoped to further utilize the drainage canals for plant and wildlife corridors through the agricultural lands of this area.

SRCD is focusing Arundo efforts in the upstream areas of the Northwest Delta to work areas of Arundo in the Lindsey Slough Complex and in the Cache Slough Complex. SRCD has already treated 3.5 acres of Arundo on Hastings Cut and surveyed both these regions and the Sacramento River to Rio Vista for existing Arundo populations. SRCD is also working with the Delta Conservancy, area Reclamation Districts, U.S. Army Corps of Engineers, California Department of Fish and Wildlife, U.S. Fish and Wildlife Service, and Team Arundo representatives to create a large scale Arundo control project with a focus on the Lindsey Slough and Cache Creek Complexes and down the Sacramento River to Rio Vista.

Habitat Benefits

The project has treated and removed Arundo from the drainage canal adjacent to Hastings cut and established native plants and grasses in the area. The segregation of cattle from irrigation and drainage canals along with the grading and planting of native vegetation stabilizes the soils, reduces erosion, increases conveyance, and provides improved habitat for birds, insects, and small mammals. The identification of Arundo infestations will inform future control efforts to remove this highly invasive non-native to increase riparian habitat, reduce fire danger along the levees, and reduce levee degradation during high flow events.
