Goal: Maintain or enhance existing Orcutt's hazardia 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 and coastal sage scrub vegetation communities.
Management units: 6, 7
Beginning in 2017, conduct routine management actions identified through 2016, 2018 and 2020 IMG monitoring of Orcutt's hazardia occurrences 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 2017, begin preparing an Orcutt's hazardia section 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 recommendations from the 2014 genetic study to provide guidance 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 Orcutt's hazardia section in the MSP Seed Collection, Banking and Bulking Plan. | Available for implementation | |
PRP-2 | Design the seed collection plan to include recommendations to collect seeds over multiple years and several times within a season, accumulate seeds across populations, and to sample among habitats and ecological niches. Include guidelines for collecting and storing seeds along maternal lines and to provide propagules to be used in management experiments, enhancement of existing occurrences, and establishment of new occurrences. | Available for implementation | |
PRP-3 | The seed collection plan should have guidelines for collecting seeds from occurrences of sufficient size to accommodate harvest. Include provisions for collecting seed from unconserved populations planned for development. | Available for implementation | |
PRP-4 | Include protocols and guidelines for collecting voucher specimens and submitting to the San Diego Natural History Museum (McEachern et al. 2007). | Available for implementation | |
PRP-5 | Include guidelines for testing seeds for viability and to obtain information on dormancy and germination rates. | Available for implementation | |
PRP-6 | Submit project metadata and the MSP Seed Collection, Banking and Bulking Plan to MSP Web Portal. | Available for implementation |

In 2017, begin preparing an Orcutt's hazardia section in the MSP Rare Plant Management Plan that prioritizes management actions to maintain or enhance occurrences on Conserved Lands (see occurrence table) based upon an assessment of data on occurrence status, habitat and threats. Minimum criteria for enhancement are to reduce invasive annual nonnative plants and thatch to less than 20% absolute cover within the occurrence
