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.

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 | |

In 2019, begin preparing a section for Orcutt's spineflower 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.
