In 2007, the Bureau of Reclamation secured 1,309 acres of land within the Cibola Valley Irrigation and Drainage District in southwestern Arizona and established the Cibola Valley Conservation Area (CVCA). In September 2007, the property was conveyed to the Arizona Game and Fish Department (AGFD) through an agreement among AGFD, Reclamation, the Mohave County Water Authority, and The Conservation Fund. Under the agreement, AGFD retains title to the property and leases the land and water rights to Reclamation until April 5, 2055 as part of the Lower Colorado River Multi-Species Conservation Program. Several farmers also have short-term leases on portions of the land for crop production.
Within the CVCA, Reclamation is planting former agricultural fields with native riparian cottonwood-willow, and mesquite habitats for species defined in the LCR MSCP Final Habitat Conservation Plan, including the southwestern willow flycatcher and yellow-billed cuckoo.
Cottonwood, willow, and honey mesquite are planted to create an integrated mosaic of habitats resembling riparian communities that were historically present in the Colorado River floodplain. When feasible, areas of standing water or moist soil, and open areas with ground cover and low shrubs are incorporated into the design.
The CVCA will be developed over a number of years through phased restoration activities. A phase-specific restoration plan is prepared each fiscal year, which documents the planning, design, planting, and monitoring requirements of that phase. An annual report is prepared each year summarizing restoration and monitoring activities conducted during the previous year.
To date, 6 phases of the site have been restored with riparian habitat, honey mesquite, and upland buffer areas in varying densities of trees per acre to help determine the most suitable planting methodology. Phases 1-3 were primarily planted with cottonwood and willow. Phases 4-6 were planted with primarily honey mesquite. No additional planting is scheduled until at least 2016 or until the long-term water requirements of Phases 1-6 both for maintenance and to meet species-specific performance standards have been quantified.

Cibola Valley Conservation Area, located in Arizona between river miles 99-104, consists of 1309 acres of land within the Cibola Valley Irrigation and Drainage District, which is being converted from a mix of active agricultural fields and undeveloped land into cottonwood-willow, honey mesquite, and desert uplands. The property, owned by Arizona Game and Fish Commission, is accessed via paved roads. You can find additional information on their main website at this link or at the LCR MSCP link here.

To date, approximately 618 acres of cottonwood-willow, honey mesquite, and upland buffer areas have been established within the CVCA. Irrigation, maintenance, and on-site management for the established habitat and areas are maintained throughout the year. Irrigation typically begins in March and concludes at the end of October. No additional plantings are scheduled until 2015.
