Article abstract: This report documents maintenance and monitoring activities for Year 5 (March 2009 to August 2010) and summarizes restoration activities to date for the vernal pool and Otay tarplant (Deinandra conjugens) restoration project at the Sweetwater Reservoir. The mitigation project includes 2.70 acres of vernal pool complex (vernal pools and associated uplands) restoration and enhancement, and 4.36 acres of Otay tarplant restoration and enhancement. Approximately 8,201 square feet (ft2) of vernal pool surface area has been restored or enhanced, which includes 3,929 ft2 of restored vernal pools. Overall, the vernal pool and Otay tarplant mitigation efforts have been moderately successful; however, all Year 5 final success criteria standards have not yet been achieved.
