Chapter 3 Conservation Strategy<br />

enhancement (LAN-1). The functionality <strong>of</strong> movement corridors across Vasco<br />

Road, SR 84, I-580, and I-680 have already been identified as important<br />

movement corridors within the study area that should be enhanced (Objective<br />

2.3). Wildlife passage through important corridors could be encouraged by<br />

using strategically placed fencing and vegetation, especially along riparian<br />

corridors and at roadway underpasses (LAN-2), and by resizing or redesigning<br />

culverts (LAN-3). A monitoring program could help identify linkages and<br />

determine the effectiveness <strong>of</strong> enhancement actions (LAN-4). This could be a<br />

grant-funded initiative that is conducted across the study area. Known and<br />

potential crossings should be identified for San Joaquin kit fox, American<br />

badger, and other highly mobile mammalian species (LAN-6). Crossings on<br />

either side <strong>of</strong> roadways should also be identified for focal species, such as<br />

California tiger salamander, which may have breeding habitat on both sides <strong>of</strong><br />

an underpass (LAN-7).<br />

To enhance regional connectivity, the coordinated mitigation and independent<br />

conservation actions would also need to protect and enhance habitat linkages<br />

between the study area and lands outside the study area (Objective 2.2). Land<br />

acquisitions related to mitigation or other conservation in eastern Alameda<br />

County could be coordinated with conservation programs in neighboring<br />

counties (LAN-5). A “Protected Lands” database should be developed to track<br />

the total acreage <strong>of</strong> each natural community and to document occurrences <strong>of</strong><br />

focal species on current parcels in the study area as well as on newly acquired<br />

parcels (Goal 3). The Implementation Committee would identify the entity that<br />

would develop, maintain, and administer this database (LAN-8).<br />

3.5.2 Natural Community–Level Goals and Objectives<br />

Conservation goals developed at the community level aim to protect and<br />

enhance the functionality and ecological value <strong>of</strong> each natural community.<br />

Goals and objectives were developed for four terrestrial communities in the<br />

study area: grassland, chaparral and scrub, oak woodland, and conifer<br />

woodland. For aquatic communities, the conservation goals mainly strive to<br />

improve the overall quality <strong>of</strong> aquatic and riparian communities as well as the<br />

hydrologic and geomorphic processes that support them to maintain functional<br />

aquatic communities. Conservation goals and objectives were developed for<br />

three aquatic communities: riparian forest and scrub, wetland and pond, and<br />

streams. By focusing protection goals and management objectives at the natural<br />

community level, the strategy would benefit focal species and native<br />

biodiversity would not decrease. Goals and objectives for each natural<br />

community are described below.<br />

To determine the best use <strong>of</strong> a conservation site, Conservation Strategy users<br />

will have to determine the most immediate conservation need on that site and<br />

manage it accordingly. Where conflicts arise between common communities,<br />

such as oak woodland and annual grassland, this management decision could<br />
