Mountain lion Puma concolor

Goal: Enhance and expand areas occupied by mountain lion in San Diego County in large interconnected blocks (>1,000 acres) of suitable natural vegetation surrounded by a limited number of high use roads, and increase connectivity (and reduce potential road mortality) between occupied and suitable habitat areas to allow expansion and movement of mountain lion occurrences within San Diego County and adjacent counties to increase effective population size to sustainable levels and work to reduce depredation on livestock to ensure persistence in the MSPA over the long-term (>100 years).

PUMCON-2 MON-EVAL-LINK In 2017-2018, guided by information from telemetry studies and mountain lion movement modelling, prioritize potential mountain lion crossing locations for SR 78, SR 76, SR 79, I-15, and other priority roads. For each priority crossing location, conduct detailed linkage assessments to identify existing impediments to successful crossings and recommendations for wildlife crossing infrastructure improvement (culvert maintenance, undercrossing construction, fencing, etc.) and habitat/land protection needs.
PUMCON-3 MGT-PRP-LINKPL Beginning in 2017 and based on linkage assessment results, prepare Linkage Implementation Plan that outlines specific locations and recommendations for improving mountain lion and deer connectivity across SR 78, 76, 79 and other priority roads in MU s 5, 8, 9, and 10.

PUMCON-9 MON-PRP-MONPL In 2020, develop a long-term monitoring strategy that integrates BMPs to document mountain lion population, connectivity and distribution within the MSPA. Monitoring plan will incorporate, as feasible: 1) possible non invasive methods for monitoring genetic connectivity (scat, hair snares, tracks, etc.), 2) methods for integrating camera trap data from various sources to answer questions regarding lion movement and distribution, and 3) a regional database to track information on lion mortalities and cause (vehicle strikes, depredation permits, illegal take, etc.) to identify problem areas and to inform management actions.
