Goal: Maintain or enhance existing San Miguel savory occurrences 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 sage scrub and oak woodland vegetation communities.

Beginning in 2018, inspect San Miguel savory occurrences 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. After 2018, repeat monitoring every 2 years.

Beginning in 2017, conduct routine management actions as identified through the IMG monitoring in 2016, 2018, and 2020 at San Miguel savory 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, begin preparing a San Miguel savory section in the MSP Seed Collection, Banking and Bulking Plan that incorporates best science and management practices (Wall 2009, KEW 2016) to preserve genetic diversity and rescue occurrences in case of catastrophic disturbance. The plan should include recommendations to collect and store 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.

In 2019, begin preparing a San Miguel savory section in the MSP Rare Plant Management Plan that prioritizes management actions to enhance at least 3 occurrences on Conserved Lands (see occurrence table) based upon an assessment of data on occurrence status, habitat and threats. Prepare prioritized management recommendations for re-establishment of historic occurrences or establishment of new occurrences in suitable habitat, if determined to be necessary for gene flow and population persistence. 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.

Valley Fire Rare Plant Discovery Surveys
A project between the SDMMP and US Forest Service to establish and prioritize survey areas on Conserved Lands within the perimeter of the 2020 Valley Fire to document whether historic occurrences are extant and to discover new occurrences for 18 rare plant species. In 2022, AECOM and Conservation Biology Institute botanists surveyed areas for 18 target rare plant species and mapped the spatial extent of each new occurrence, counted or estimated the occurrence population size, and collected voucher specimens. They also photographed each new occurrence from a georeferenced location that captured a representative view of the occurrence. Botanists created a species list for the areas surveyed within the Valley Fire footprint. These areas included locations where rare plants were detected and mapped and negative data point areas where rare plants were not detected. In 2023, botanists shall again conduct surveys on suitable habitat on USFS lands burned in the 2020 Valley Fire. Results from these surveys should lead to a greater understanding of post-fire rare plant composition. In 2023, botanists may see species that did not emerge in the first year of surveys, and species found in the first year of surveys may have expanded their range. The 18 rare plant species included in the surveys are: San Diego thornmint (Acanthomintha ilicifolia), Marvin's allium (Allium marvinii), Western spleenwort (Asplenium vespertinum), Deane's milkvetch (Astragalus deanei), Encinitas baccharis (Baccharis vanessae), San Diego goldenstar (Bloomeria clevelandii), Orcutt's brodiaea (Brodiaea orcuttii), Lakeside ceanothus (Ceanothus cyaneus), San Miguel savory (Clinopodium chandleri), Variegated dudleya (Dudleya variegata), Mission Canyon bluecup (Githopsis diffusa filicaulis), Ramona horkelia (Horkelia truncata), Heart-leaved pitcher sage (Lepechinia cardiophylla), Felt-leaved pitcher sage (Monardella hypoleuca lanata), Chaparral nolina (Nolina cismontana), Gander's ragwort (Packera ganderi), Moreno currant (Ribes canthariforme), and Parry's tetracoccus (Tetracoccus dioicus).

Occurs in Orange County, Riverside County, San Diego County, and Baja California, Mexico, at elevations between 120 and 1,005 m [1,2,3].
Very rare shrub in San Diego County (one of Southern California's rarest shrubs).Found on San Miguel Mountain, north of San Vicente Reservoir, and north of Padre Barona Creek with historic sightings from other areas [1]. Within MSPA, there are three occurrences on Conserved Lands [4]. In MU3, there are occurrences at Mount Miguel and in the Jamul Mountains while MU4 has a small occurrence at Boulder Oaks Preserve.
None
Associated with rocky, gabbroic and metavolcanic substrates in coastal sage scrub, chaparral, cismontane woodland, riparian woodland, and valley and foothill grasslands [2,3]. In San Diego County, found on chamise dominated slopes on Los Posas stony fine sandy loams or San Miguel Exchequer rocky silt loam soils [1].
Newly classified in the genus Clinopodium within the Lamiaceae family [5]. Previously placed in the genus Satureja, however molecular DNA evidence demonstrated this genus was not part of a monophyletic grouping.
Perennial shrub is branched and upper parts are pubescent (hairs short, white). Ranges in height from 2 to 5 dm [6].Flowers grow from the leaf axils in clusters of one to six and range in color from white to lavender. Two-lipped flowers are 4 to 7 mm long. Nutlets are shiny and dark brown, and 1.5 mm in diameter [7].
Flowers from March through July [2,6].
No information on pollinators or seed dispersal.
Threatened by agricultural conversion, urban development and recreational activities; may be threatened by horticultural collecting [3].
No information.
