Goal: Maintain or enhance existing Encinitas baccharis 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.

Beginning in 2017, inspect Encinitas baccharis occurrences on Conserved Lands (see occurrence table) using the regional IMG monitoring protocol to record abundance and collect habitat and threat covariate data to determine management needs. After 2017, repeat monitoring every 2 years.

Beginning in 2017, conduct routine management actions identified through the IMG monitoring at Encinitas baccharis 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 2017, continue a study begun in 2016 to characterize the population genetic structure, gene flow, and genetic diversity for Encinitas baccharis occurrences (see occurrence table). The study will determine if there is evidence of mixed ploidy levels within or among occurrences; evaluate vulnerability of occurrences to genetic drift and loss of genetic diversity; assess the level of gene flow among occurrences; identify if there are signatures of genetic bottlenecks or low genetic diversity in occurrences that have undergone recent reductions; and look for evidence of local population adaptation. Based on the results of the genetic analyses, management recommendations will include whether common garden and reciprocal transplantations are necessary before proceeding with population enhancement or restoration and will provide specific recommendations for collecting, bulking and distributing seed to enhance existing occurrences or establish new occurrences.

In 2018, begin preparing a section for Encinitas baccharis 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 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 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.

Begin preparing a section for Encinitas baccharis in the MSP Rare Plant Management Plan that prioritizes management actions to maintain or expand occurrences on Conserved Lands based upon an assessment of data on occurrence status, habitat and threats. Prioritize management recommendations to maintain large occurrences and enhance at least 3 small occurrences (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.

Determine the population dynamics of Encinitas baccharis in response to natural and altered fire frequencies that may affect successional processes and population dynamics. The study should begin when the next fire burns an Encinitas baccharis occurrence and include subsequently burned occurrences to research post-fire recovery mechanisms (e.g., resprouter vs. obligate seeder) and circumstances in which post-fire management is necessary to facilitate robust post-fire recovery. Use results to identify postfire management actions for Encinitas baccharis to assist in recovery of burned populations.
