Climate Action Plan - Measure T-1.1

 Open Space Conservation

The County preserves San Diego’s unique, native habitats and wildlife biodiversity for future generations through the County’s Multiple Species Conservation Program (MSCP). The County uses the MSCP program to acquire land and place it into permanent conservation. This removes the threat of future development, the loss of critical habitat, and reduces the emissions that would have occurred if the land were developed. 
  • 2020 Target: Acquire 2,622 acres
  • 2030 Target: Acquire 6,992 acres

Open Space Land Acquired

How are we doing?

Since 2014, the County has acquired 3,628 acres, achieving the 2020 target two years ahead of schedule! The County meets goals and climate action targets by coordinating with land acquisition partners to acquire, manage, and monitor preserved lands while also engaging the public in education about the value of these exceptional resources. In 2018, in partnership with Escondido Creek Conservancy and the US Navy, the County acquired the 670-acre Mountain Meadow preserve to protect California gnatcatcher and orange throated whiptail habitat within willow scrub, chaparral, and Engelmann and coast live oak woodland.
Through acquisitions, the County works to restore and enhance habitat of the endangered Quino checkerspot butterfly and conduct studies on species such as the Pallid bat, big-eared bat, eagles, and raptors to inform management decisions. Through active restoration projects such as at the 1.4-acre El Monte Park in 2016, native plant species including the San Diego sunflower, coyote brush, California lilac and three types of sage were propagated and are now thriving.

How is this measured?

Acquisition of land by the County supports Climate Action Plan goals by reducing greenhouse gas (GHG) emissions through the preservation of land that could otherwise be developed. Emissions reductions occur by avoiding the transportation, energy use, waste, and water consumption associated with development for residential or commercial purposes. For example, conserving 6,992 acres of open space land by 2030 is equivalent to avoiding emissions from 184 dwelling units.

Why is this important?

San Diego county hosts one of the most diverse habitats for plants and animals with the highest number of species considered rare or endangered in the United States. Preservation of land within the unincorporated county helps connect habitat and wildlife migration corridors, protect watersheds, improve ecosystem health, preserve vegetation, and also sequester carbon. After acquisition, programs are put in place to manage, maintain, and monitor the plant and animal life as part of a preserve to ensure species are flourishing, healthy, and thriving.

Where are we going?

The Department of Parks and Recreation is committed to restoring and enhancing our open space. The County plans to acquire 6,992 acres by 2030. Preservation is targeted within habitat areas with high biological value. The County will actively maintain, manage, and monitor open space and provide recreational opportunities for a growing San Diego. Specifically, the County plans to add the endangered Quino checkerspot butterfly to the list of species covered by the MSCP Plan for the South County Subarea. The County will use data gathered in a three-year study on eagle and raptor foraging activities to inform management decisions for the Ramona Grasslands Preserve.
