Goal: Maintain or enhance existing aphanisma occurrence(s) and establish new occurrences, as needed, to ensure multiple conserved occurrences with self sustaining populations to increase resilience to environmental and demographic stochasticity, maintain genetic diversity, and improve chances of persistence over the long term (>100 years) in coastal bluff, coastal dune and coastal sage scrub vegetation communities.
Management units: 1, 7
Beginning in 2017, inspect extant aphanisma occurrence(s) on Conserved Lands (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. After 2017, repeat monitoring every 2 years, unless an occurrence is small (<100 individuals) or faces a high degree of threat, in which case monitor annually.

Beginning in 2017, conduct routine management actions as identified through the IMG monitoring at aphamisma occurrence(s) on Conserved Lands (see occurrence table). Depending on the type and level of threat, management should be conducted as needed, not necessarily every year, and using BMPs with precautions to do no harm.

In 2019, survey historic aphanisma locations to determine occurrence status; survey and delineate potentially suitable habitat for new occurrences; survey existing occurrences to identify the potential for enhancement and expansion; and at all sites collect data on occurrence status, habitat and threats and determine management needs.
| Action | Statement | Action status | Projects |
|---|---|---|---|
| SURV-1 | At each extant occurrence, map the extent of the occurrence, collect data on abundance, map adjacent suitable habitat for potential occurrence expansion, collect covariate data on threats including estimates of cover of invasive non-native plants and trampling. | On hold | |
| SURV-2 | Submit project metadata, habitat mapping, occurrence status, habitat and threats assessments, management recommendations, and report to the MSP Web Portal. | On hold |
