San Diego, CA – Del Mar Mesa Preserve Faces Tensions Between Conservation and Recreation

San Diego’s Del Mar Mesa Preserve is experiencing growing tensions between conservation efforts and recreational activities, as stakeholders debate the balance between habitat protection and public enjoyment.

Conservation Efforts Intensify

Protect Our Preserves, Inc., a nonprofit organization dedicated to habitat preservation in San Diego, has been actively involved in the Del Mar Mesa Preserve since its formation in 2018. The organization focuses on the preservation, enhancement, and restoration of habitats through education, outreach, grants, and fundraising. Their mission includes protecting areas like Del Mar Mesa Preserve, Los Peñasquitos Canyon Preserve, and Carmel Mountain Preserve, which serve as valuable habitats for various plant and animal species.

Recreational Use and Its Impact

The Del Mar Mesa Preserve offers opportunities for passive recreational activities such as hiking, bird watching, and mountain biking. However, concerns have arisen regarding the impact of these activities on the preserve’s natural resources. Excessive or uncontrolled access can lead to habitat degradation through trampling, erosion, and disruption of critical wildlife functions.

Community Response and Management Plans

The Del Mar Mesa Community Planning Board has emphasized the importance of balancing conservation with recreational use. They advocate for recreational activities that are consistent with the protection and enhancement of biological resources. The board has highlighted the need for trail designs and usage rules that foster a calm and enjoyable experience for people of all ages and abilities in natural areas.

Ongoing Discussions and Future Outlook

As the debate continues, stakeholders are working to find a harmonious balance between preserving the ecological integrity of the Del Mar Mesa Preserve and accommodating recreational activities. Ongoing discussions aim to develop management plans that protect sensitive habitats while allowing public access in a sustainable manner.

Background Context

The Del Mar Mesa Preserve is part of the larger Los Peñasquitos Canyon Preserve, which stretches seven miles from the I-5/I-805 merge on its western edge to just east of I-15. The main attraction of the Del Mar Mesa Preserve is a large concentration of scrub oak trees. A collection of trails routed through these trees became known as “Tunnels” due to the sprawling and interconnected branches that formed a canopy over the trails, providing a unique experience for hikers and bikers.

Protect Our Preserves, Inc. was formed in 2018 in response to a proposed 450,000 square foot business park on an 11-acre Del Mar Mesa “notch” surrounded on three sides by the Del Mar Preserve. The organization focuses on the preservation, enhancement, and restoration of habitats through education, outreach, grants, and fundraising.

The Del Mar Mesa Community Planning Board is the elected advisory body on land-use issues within the community, providing guidance to the City of San Diego’s Planning Commission and City Council. The board emphasizes the importance of preserving natural resources and balancing them with recreational use.

As discussions continue, stakeholders are working to develop management plans that protect sensitive habitats while allowing public access in a sustainable manner. The goal is to ensure the long-term viability of the plant and animal communities that inhabit the area.
