Chapter 3 Conservation Strategy
placed fencing and vegetation, especially along riparian corridors and at
roadway underpasses.
• Conservation Action LAN-3. Where biologically appropriate, resize or
redesign culverts to better accommodate wildlife passage under major
roadway barriers.
• Conservation Action LAN-4. Fund and implement a monitoring program both
to identify important linkages along major barriers and to determine the
effectiveness of enhancement actions at protected undercrossing points
Objective 2.2. Protect and enhance habitat linkages between the study area and
lands outside of the study area to enhance regional connectivity.
• Conservation Action LAN-5. Coordinate acquisitions related to mitigation or
other conservation in eastern Alameda County with conservation programs
in adjacent counties.
Objective 2.3. Retain, and if possible, increase the functionality of movement
corridors across Vasco Road, the South Bay Aqueduct, SR 84, I-580, and I-680 for
a range of species to move safely within and through the study area.
• Conservation Action LAN-6. Identify known crossings and potential
crossings for San Joaquin kit fox, American badger, and other highly mobile
mammalian species.
• Conservation Action LAN-7. Identify existing crossings with suitable habitat
for focal species on both sides of the roadway (e.g., crossings with California
tiger salamander breeding habitat on both sides of the underpass).
Goal 3
Maintain a coordinated “Protected Lands” database that tracks the total
acreage of each natural community as well as documented occurrences of focal
species on current and newly acquired parcels in the study area.
Objective 3.1. Develop, maintain, and administer a protected lands database.
3.5.1.2 Regional Connectivity and Habitat Linkages
Landscape-level goals are intended to maintain and enhance the effective
movement and genetic exchange of native organisms within and between
natural communities inside and outside the study area (Goal 2). In order to
maintain connectivity for wildlife populations within the study area, projectdriven
mitigation and independent conservation actions would need to protect
and enhance functional linkages across major highways (e.g., I-580 and I-680) to
allow for movement of species (Objective 2.1). Initially, the Implementation
Committee could identify important linkages and “pinch-points” (migration
areas with restricted or disturbed corridors) to prioritize for protection or
