Goal: Maintain, enhance and restore coastal sage scrub on Conserved Lands in the MSPA that supports or has the potential to support VF species (i.e., cliff spurge, Palmer's goldenbush, San Diego barrel cactus, snake cholla, Blaineville's horned lizard, California gnatcatcher, San Diego black-tailed jackrabbit) and to incidentally benefit a diverse array of other species (e.g., San Diego thornmint, willowy monardella, Hermes copper, Quino checkerspot, coastal cactus wren) so that the vegetation community has high ecological integrity, and these species are resilient to environmental stochasticity, catastrophic disturbances and threats, such as very large wildfires, invasive plants and prolonged drought, and will be likely to persist over the long term (>100 years).
Management units: 3, 4, 5, 6, 7
In 2021, inspect occurrences of coastal sage scrub MSP VF plant species (cliff spurge, Palmer's goldenbush, San Diego barrel cactus and snake cholla) on Conserved Lands using the regional IMG monitoring protocol to record abundance and collect habitat and threat covariate data to determine management needs.

San Diego County and Baja California [1].
Thirteen occurrences on Conserved Lands in Mus 3 (Lawrence and Barbara Daley Preserve, McGinty Mountain Ecological Reserve, San Diego National Wildlife Refuge), 4 (Louis A. Stelzer County Park), 5 (Boden Canyon Ecological Reserve), 6 (Hodges Reservoir Open Space), and 7 (Aviara Master HOA).
None [1].
Mesic chaparral and coastal scrub [1]. Elevation range 30-600 meters. Las Posas fine sandy loam and Vista coarse sandy loam [2].
Asteraceae family [1].
Perennial evergreen shrub [1].
Bloom period July-November [1].
Bees and butterflies are pollinators [3]. Late bloom when little else is in flower makes it important for pollinators [4].
Development, road construction, road maintenance, and off-road vehicles [1].
