In Maricopa County, the Army Corps of Engineers has completed a series of flood control projects. The problem of revegetating those areas disturbed by construction usually follows completion of each project. A number of approaches to this problem have been taken by the Corps with various degress of success. As future flood control projects are planned for Maricopa County and the Arizona desert area, there is a need to review past projects. Three Corp projects Dreamy Draw Dam, Indian Bend Wash and Cave Buttes Dam have been examined in terms of the revegetation techniques utilized and the overall effectiveness of these measures in re-establishing vegetation. In each of these projects, seeding was the primary method of re-establishing vegetation. A successful seeding operation is dependent upon three major factors preparing the seedbed, selecting suitable plant species, and properly planting the seed. The individual projects were reviewed considering these factors and the results of in-field vegetation sampling are presented in order to demonstrate overall seeding effectiveness. Based on these reviews and observations, a comprehensive conclusion of the three sites is presented with corresponding recommendations for revegetation projects in Maricopa County.
