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.
Management units: 3, 4, 6
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.
