The San Diego River Conservancy has created a watershed-wide program for invasive species management. The Ward Road site invasive species removal of 17 acres was completed in 2013. The 25-acre Carlton Oaks Golf Course site contains both public and private land, and should be completed by 2015.
Through this program, the SDRC has mapped all of the Arundo and other target invasive species in the watershed, has received watershed-wide permits, and has completed a watershed-wide Mitigated Negative Declaration under the California Environmental Quality Act that covers the whole program. SDRC has successfully completed two Arundo eradication projects within the watershed, restoring 58 acres of the 354 acres of invasive plants that were initially mapped. The watershed-wide program is focused on eradicating Arundo from the entire watershed using proven methods of treatment, retreatment, and revegetation.
