The Rancho La Costa Preserve parcels were deeded to the Center for Natural Lands Management (CNLM) between 2001 and 2011. This site has been protected to mitigate for impacts to coastal sage scrub and other vegetation communities as a result of development projects in the vicinity, including the La Costa Villages (Morrow Development), and University Commons residential developments (Brookfield Homes and Skandia). This Preserve acts as a regional corridor connecting the Batiquitos Lagoon and Lake Hodges. Although the site is broken into many parcels, the land owned by the CNLM is approximately 1,640 acres. The Preserve includes Box Canyon, a very steep, but unique feature of the area.
This Preserve is a biologically rich site and representative of the high diversity of coastal San Diego County’s natural habitats. More than 80% of this Preserve is covered in two native habitat types, coastal sage scrub and mixed chaparral as well as a few acres of cottonwood woodland located within Box Canyon. Several threatened or endangered species occur on this site, including Del Mar Manzanita (Arctostaphylos glandulosa crassifolia), coastal California gnatcatcher (Polioptila californica californica), San Diego thornmint (Acanthomintha ilicifolia), Orcutt’s hazardia (Hazardia orcuttii) and thread-leaved brodiaea (Brodiaea filifolia).
Our prime goal for this Preserve is to protect the habitats and species that depend upon this protected area for survival. The focus of our work is to protect the Preserve from negative human abuses, remove non-native plant species, monitor plant and wildlife species, and conduct research projects. These research studies focus on whether or not the conserved natural communities and species can persist, for how long, as well as determining specific management methods required to reduce their risk of extirpation.
There are over 15 miles of trail at the Preserve. Hiking is allowed on all trails; mountain biking is also allowed on some trails. Dogs-on-leash are allowed in all areas but Copper Creek. Please stay on trail and note trail signage. Hike to the viewpoint on Denk Mountain and enjoy the 3600 view!
