Article abstract: Mountain lions (Puma concolor, puma, cougars) are top carnivores and important ecological regulators that roam widely throughout the San Diego County landscape. Puma concolor is a named species in regional conservation plans. Because of the extensive areas required by each mountain lion, multiple Natural Conservation Community Planning (NCCP) areas are often utilized by a single individual. Thus, connectivity within and between NCCPs is important for long-term health and persistence of mountain lions in the landscape, and proper NCCP function. In addition to the currently approved NCCP areas in Southern California, San Diego County is in advanced stages of preparing a conservation preserve design for its North County Multiple Species Conservation Program (NCMSCP). This research project uniquely combined camera, GPScollar, and mortality data with state of the art genetic analyses and modeling, and an expert workshop, to produce the most comprehensive assessment to date of mountain lion habitat use and connectivity within, and adjacent to, the NCMSCP area.
