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.

In 2021, begin preparing a section for aphanisma in the MSP Seed Collection, Banking and Bulking Plan to preserve genetic diversity and rescue occurrences in case of catastrophic disturbance. The plan should incorporate best science and management practices (Wall 2009; KEW 2016) and provide guidelines for collecting and storing seeds over the long term at a permanent, established conservation seed bank (e.g., Institute for Conservation Research Native Plant Seed Bank, Rancho Santa Ana Botanic Garden Seed Conservation Program) and for providing a source of seeds for management purposes. The plan should include recommendations for: collecting and storing seeds for conservation banking; management oriented research; rescuing occurrences after catastrophic disturbances; and seed bulking and out-planting to augment extant occurrences or to establish new occurrences with consideration of genetic implications for population sustainability.

PRP-1 | Consult the San Diego County Rare Plant Working Group made up of plant ecologists, geneticists, rare plant experts, land managers, restoration practitioners, seed banking and bulking practitioners, wildlife agencies, and other stakeholders to provide input and recommendations for the aphanisma section of the MSP Seed Collection, Banking and Bulking Plan. | some occurrences are in progress | |
PRP-2 | Write a seed collection plan section that includes collecting seeds over multiple years and several times within a season, accumulating seeds across populations, and sampling among habitats and ecological niches. Include guidelines for collecting and storing seeds along maternal lines from occurrences with <1,000 plants and to provide propagules to be used in management experiments, enhancement of existing occurrences, and establishment of new occurrences. | some occurrences are in progress | |
PRP-3 | The seed collection plan section should include guidelines for collecting seeds from occurrences of sufficient size to accommodate harvest and based on genetic studies as available. Include provisions for collecting seed from unconserved populations planned for development. | some occurrences are in progress | |
PRP-4 | Include protocols and guidelines for collecting voucher specimens and submitting to the San Diego Natural History Museum (McEachern et al. 2007). | some occurrences are in progress | |
PRP-5 | Include guidelines for testing seeds for viability and to obtain information on dormancy and germination rates. | some occurrences are in progress | |

In 2021, begin preparing a section for aphanisma in the MSP Rare Plant Management Plan that prioritizes management actions to maintain and expand conserved occurrences based upon an assessment of data on occurrence status, habitat and threats. Prioritize management recommendations for re-establishment of historic occurrences and/or establishment of new occurrences in suitable habitat as needed to achieve at least 3 occurrences with self-sustaining populations on Conserved Lands (see occurrence table). Minimum criteria for enhancement are to reduce invasive annual nonnative plants and thatch to less than 20% absolute cover within the occurrence
