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
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.
