Habitat Connectivity - Ventura County [ds565]

A Linkage Design addresses the potential movement needs for several focal species. For more details on the methods used for creating each Linkage Design refer to the individual linkage reports at http://www.scwildlands.org/reports.aspx This 'Linkage Designs' feature class delineates the outer-boundaries of 12 critical landscape linkages identified by the South Coast Missing Linkages Project. The 3 cross-border landscape linkages are not included in this generalized feature class. The complete set of linkages mapped by South Coast Missing Linkages covers all of Southern California. However, for purposes of planning within Ventura County, this layer has been clipped to the linkages within Ventura County and immediately adjacent to it. 1. Santa Monica - Sierra Madre The Santa Monica-Sierra Madre Connection encompasses habitats between the Santa Monica Mountains National Recreation Area (south of the 101 Freeway) and Los Padres National Forest. The Linkage Design addresses the habitat and movement needs of 20 focal species including Puma concolor (Mountain lion), Taxidea taxus (American badger), Odocoileus hemionus (Mule deer), Sylvilagus bachmanni (Brush rabbit), Neotoma lepida (Desert woodrat), Lanius ludovicianus (Loggerhead shrike), Toxostoma redivivum (California thrasher), Melanerpes formicivorus (Acorn woodpecker), Campylorhynchus brunneicapillus (Cactus wren), Bufo boreas (Western toad), Lampropeltis getula (California kingsnake), Cnemidophoris tigris stejnegeri (Western whiptail), Oncorhynchus mykiss mykiss (Southern steelhead trout), Anuroctonus phaiodactylus (Scorpion), Odonata - Zygoptera spp. (Damselflies), Euphydryas chalcedona (Chalcedon checkerspot butterfly), Pogonomyrmex rugosus (Harvester ant), Juglans californica (California walnut), Quercus lobata (Valley oak), and Arctostaphylos glauca (Bigberry manzanita). Please see the full report, South Coast Missing Linkages Project: A Linkage Design for the Santa Monica-Sierra Madre Connection (http://www.scwildlands.org/reports.aspx) for more information. The 'Santa Monica - Sierra Madre' feature addresses two of the 15 priority linkages. 2. Sierra Madre - Castaic The Sierra Madre-Castaic Connection links the Sierra Madre Mountains of Los Padres National Forest and the Castaic Ranges (Liebre, Sawmill, and Sierra Pelona mountains) of the Angeles National Forest. The Linkage Design addresses the habitat and movement needs of 12 focal species, including Puma concolor (Mountain lion), Taxidea taxus (American badger), Odocoileus hemionus (Mule deer), Dipodomys agilis (Pacific kangaroo rat), Strix occidentalis occidentalis (California spotted owl), Melanerpes formicivorus (Acorn woodpecker), Clemmys marmorata (Western pond turtle), Thamnophis hammondii (Two-striped garter snake), Lampropeltis zonata (California mountain kingsnake), Ensatina eschscholtzii eschscholtzii (Monterey salamander), Arctonotus lucidus (Bear sphinx moth), and Pleocoma linsleyi (Rain beetle).
