Goal: Maintain or enhance existing Orcutt's spineflower 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: 6, 7
Beginning in 2017, conduct annual surveys of all Orcutt's spineflower.

Beginning in 2017, conduct routine management actions as identified through the IMG monitoring at Orcutt's spineflower occurrences on Conserved Lands (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.

In 2017, continue efforts begun in 2015 to survey historic Orcutt's spineflower locations to: determine current 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. | In progress | |
| SURV-2 | Submit project metadata, habitat mapping, occurrence status, habitat and threats assessments, management recommendations, and report to the MSP Web Portal. | In progress |
| Criteria | Deadline year |

In 2017, continue BMPs initiated in 2015 to establish 4 new occurrences of Orcutt's spineflower.
| Action | Statement | Action status | Projects |
|---|---|---|---|
| IMP-1 | Establish 4 new occurrences of Orcutt | in progress | |
| IMP-2 | Use BMPs for site preparation (Bauder 2010a,b). Sites with ice plant or Acacia shrubs should be cleared of these invasive plants and duff and then watched for at least 2 years with suitable growing conditions to determine if there are viable spineflower | in progress | |
| IMP-3 | Maintain newly established occurrences so that there is <20% invasive non-native absolute cover, minimal encroachment of native plants (based upon standards used at the Point Loma Naval Base), and no ground disturbance from erosion or trampling. | in progress | |
| IMP-4 | Use the seed collection and bulking plan to determine seed sources and timing and amount of seeding. | in progress | |
| IMP-5 | Submit project metadata, monitoring and management data to MSP web portal. | in progress |
| Criteria | Deadline year |
