Goal: Maintain or enhance existing Orcutt's brodiaea 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, grassland, oak woodland, southern interior cypress forests, and vernal pool vegetation communities.
Management units: 2, 3, 4, 6, 8
From 2017-2021, inspect Orcutt's brodiaea occurrences annually 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.

Beginning in 2017, conduct routine management actions identified through the IMG monitoring at Orcutt's brodiaea 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 2019, survey historic Orcutt's brodiaea 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 |

Beginning in 2017, establish 2 new Orcutt's brodiaea occurrences at Proctor Valley and Cal Terraces/Dennery Canyon. Invasive plant control should be conducted using BMPs so that invasive plants are reduced to less than 20% absolute cover within the occurrence
