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).

MON-EVAL-LINK PUMCON-2

Management units: 5, 8, 9, 10

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.
Action Statement Action status Projects
EVAL-1 Use telemetry and modelling data to inform important wildlife crossing locations along SR 78, SR 76 and SR 79 where follow up surveys will be conducted to identify specific locations and recommendations for wildlife crossing infrastructure improvements. in progress Mountain Lion Connectivity and Genetics Study- North San Diego County
EVAL-2 At each location, detailed field assessments will be performed to identify existing impediments to successful crossings, specific recommendations for wildlife crossing infrastructure improvements, and land protection needs in the area defined in order to provide for long term successful connectivity between protected lands for mountain lions and other wildlife. in progress Mountain Lion Road Crossing and Deterrent Methods Evaluations

PUMCON-1 MON-RES-SPEC In 2017, finalize efforts begun in 2016, using available regional mountain lion movement data, to develop quantitative models of mountain lion movement in the MSPA to validate likely movement patterns and to assist with linkage and land protection prioritization.
