Article abstract: This study presents an approach for identifying and describing geographic areas that support edaphic endemic species and their habitat in a design that enhances resilience and provides opportunities for shifting distributions. We developed conceptual models to inform field studies and management, refined soils and vegetation attributes, and assessed regional population structure and threats. We used results to suggest prioritized locations for surveys, management, potential translocation, and additional conservation or acquisition. The U.S. Geological Survey (USGS) and San Diego Management and Monitoring Program (SDMMP) modeled suitable habitat for the target species under current and future climate scenarios; model results are in a separate report and referenced in this document, as appropriate. Target species include San Diego thornmint (Acanthomintha ilicifolia), thread-leaved brodiaea (Brodiaea filifolia), Otay tarplant (Deinandra conjugens), Dehesa nolina (Nolina interrata), and Parry’s tetracoccus (Tetracoccus dioicus).
