Goal: Maintain or enhance existing San Diego ambrosia occurrences to ensure multiple conserved occurrences with self sustaining populations to increase resilience to environmental and demographic stochasticity, maintain genetic diversity, and ensure persistence over the long term (>100 years) in chaparral vegetation communities.
Management units: 3, 4, 6, 8
Beginning in 2017, annually inspect San Diego ambrosia occurrences on Conserved Lands in (see occurrence table) using the regional rare plant IMG monitoring protocol to record abundance and collect habitat and threats covariate data to determine management needs.

Management units: 3, 4, 6, 8
Beginning in 2017, conduct routine management actions identified through the IMG monitoring at San Diego ambrosia occurrences on Conserved Lands in (see occurrence table). Depending on the type and level of threat, management should only be conducted as needed, not necessarily every year, and using BMPs with precautions to do no harm.
