San Diego Management & Monitoring ProgramSilverwood Wildlife Sanctuary, owned and operated by San Diego Audubon since 1966, is maintained to preserve 787 acres of prime coastal chaparral and riparian woodland habitat in San Diego County, consistent with objectives described in the Management Strategic Plan (MSP). Like much of San Diego County, sensitive wildlife in the preserve is threatened by the presence and potential spread of invasive non-native plant species. This project supports the implementation of invasive plant control in priority habitat areas within the preserve. The primary goal is to reduce extant populations of invasive species and prevent their further spread. Project objectives include treatment of approximately 65 acres of invasive species hot spots with herbicide and approximately 5 acres of emergent invasive species treated via hand management, reducing invasive cover by 90% within the 18-month grant term. This funding is a priority and imminent need for the preserve, largely due to drought-caused, elevated instances of invasive species that threaten high-quality habitat.
