Conservation Significance

The Manchester Preserve is a biologically rich site representative of the high diversity of coastal San Diego County’s natural habitats. Over 80% of this Preserve is covered in two native habitat types, Diegan sage scrub and southern maritime chaparral. Several threatened or endangered species occur on this site including the San Diego thornmint, Del Mar Manzanita, Orcutt’s hazardia, and the California gnatcatcher. The Preserve has a varied topography, ranging from a gently sloping canyon bottom to extremely steep canyon walls, with elevations ranging from 40 to 275 feet above sea level.

Our Work

Our primary management goal for this Preserve is to control invasive non-native plant species and facilitate public use to ensure compatibility between the general public and the needs of the imperiled species that exist on the Preserve.  This site is in a highly urban-suburban setting and presents unique challenges in our stewardship activities, including identifying the best and most effective techniques to reduce the risk of extirpation of the  San Diego thornmint, Del Mar manzanita, Orcutt’s hazardia, and California gnatcatcher on the Preserve.
