Goal: Maintain or enhance existing Dehesa beargrass 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 ensure persistence over the long term (>100 years) in chaparral vegetation communities.
Management units: 3
Beginning in 2017 and continuing every 5 years, thereafter, continue inspections of Dehesa beargrass occurrences on Conserved Lands (see occurrence table) begun in 2014 using the IMG regional monitoring protocol to record abundance/map perimeters and collect threats and covariate data to determine management needs.

Beginning in 2017, conduct routine management actions begun in 2014 identified through the IMG regional protocol monitoring on Conserved Lands. 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, begin field research into soils and habitat relationships and conduct habitat suitability and climate change modeling for Dehesa nolina and other edaphic endemic plants to better understand habitat requirements and to identify and prioritize geographic areas important for connectivity, restoration, and range shifts due to climate change and other threats.
