Goal: Maintain or enhance existing coast wallflower occurrences 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 chaparral, coastal bluff, coastal dune and coastal sage scrub vegetation communities.
Management units: 6, 7
Beginning in 2017, inspect occurrences of coast wallflower on Conserved Lands (see occurrence table) using the regional IMG monitoring protocol to record status and to collect habitat and threats covariate data to determine management needs. After 2017, repeat monitoring every 2 years.

Beginning in 2017, conduct routine management actions as identified through the IMG monitoring at coastal wallflower 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 2021, begin preparing a section for coast wallflower 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 (e.g., Wall 2009; KEW 2016) to 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 to provide source material with consideration of potential genetic consequences; for management oriented research; seed bulking; and out-planting to augment extant occurrences or establish new occurrences.

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 coast wallflower section in the MSP Seed Collection, Banking and Bulking Plan. | some occurrences are in progress | |
PRP-2 | Prepare a seed collection plan to collect seeds over multiple years, collect seeds 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 from small occurrences (<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 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 | |

In 2021, begin preparing a section for coast wallflower 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 or establishment of new occurrences in suitable habitat, as needed, to achieve at least 4 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

Rare Plant Inspect and Manage Monitoring 2014-2026
From 2014-2026, a Management and Monitoring Strategic Plan (MSP Roadmap) monitoring objective for 30 rare plant species is to inspect occurrences to determine management needs. The inspect and manage (IMG) objective is implemented to document the status of rare plant occurrences and assess habitats and threats to develop specific management recommendations. IMG monitoring is implemented by a combination of land managers and contracted biologists in coordination with the SDMMP. Available rare plant data is posted below. New annual updates are typically posted in March. Based upon an evaluation of these data, a 2014-2026 monitoring schedule has been developed for the 30 rare plant species (attached below). Coordinating data collection across the region allows analyses of species and population trends over time and provides a better understanding of the association between habitat and threat covariates and population dynamics.

Management Strategic Plan (MSP) 2015 Monitoring Protocol for Rare Plant Occurrences on Conserved Lands in Western San Diego County | San Diego Management and Monitoring Program | 2015 | report |
Endemic to California [1]. Reported from San Diego County, Santa Rosa Island, Santa Cruz County, and Monterey County [2].
Within the MSPA, two extant occurrences in MUs 6 and 7 [3]. In MU6, found in east Del Mar at Overlook Park and in MU7, found at Crest Canyon.
None.
Occurs below 60m elevation in sandy areas and openings in maritime chaparral, coastal dunes, and coastal scrub [4]. Reported in eroded dunes away from the existing beachline, and sandy locales in chaparral openings [2]. Locations at Torrey Pines State Park map to Corralitos loamy sand and locations at Camp Pendleton map to Olivenhain cobbly loam.
Originally classified in more widespread and inland species, Erysimum capitatum ssp. capitatum. More recently combined with coastal Santa Cruz and island populations into E. ammophilum [5].
Family Brassicaceae.
Yellow-flowered perennial, blooms February-June [4]. Elsewhere reported as biennial [2].
No information.
Close to extirpation in San Diego County [2].Threatened by development [4]. As with other coastal strand and dune plants, likely to have been adversely affected by coastal development, human disturbance and competition with non-native invasive plants.
