The Conservation Biology Institute developed a science-based Conservation Vision and
Management Strategy for Dehesa nolina in San Diego County. The Conservation Vision
assessed the distribution, status, and threats of populations on conserved lands through data and
literature reviews, site visits, and interviews with land managers. Products included spatial data
layers, an updated matrix of threats and stressors, management recommendations, and prioritized
populations for management.

The Management Strategy focused on preserve-level management, using the existing Dehesa
nolina population on the South Crest Preserve to test/refine management techniques, including
species augmentation (seed collection, contract growing of plants, out-planting) and erosion
control. These actions also benefitted Dudleya variegata (variegated dudleya) and sensitive
native grassland habitat. These management actions complemented other Transnet-funded
management on South Crest; techniques refined in this project are applicable to other conserved
populations in the region. Project partially funded by SANDAG TransNet EMP Land Management Grant #5001763
