Our landscape blocks, which may be any shape, were identified in June 2013 based on protected lands including: 1) lands managed primarily for biodiversity conservation (based on USGS GAP Analysis conservation status designations GAP 1 and 2); 2) mixed use public lands (USGS GAP 3) that intersect with Large Intact Blocks identified by the California Essential Habitat Connectivity project (i.e., areas of high ecological integrity that are >10,000 acres in size); and, 3) lands under conservation easement. Landscape blocks included all land parcels 100 acres or larger that met our conservation status criteria. A one kilometer buffer was added to all land parcels to form blocks of land. We split our landscape blocks by major rivers and roads to identify barriers within blocks. For more information see the project report at [https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=85358]. The 246 landscape blocks are habitat areas, based on protected lands, in the northern Sierra Nevada foothills and neighboring ecoregions. Least-cost corridors for nine focal species, riparian connections, and land facets were modeled between the 271 landscape blocks for the northern Sierra Nevada foothills wildlife connectivity project. 20140609 publication date Complete As needed -122.596798 -119.542932 40.992619 36.812052 None landscape blocks northern Sierra Nevada foothills wildlife connectivity None California None The user accepts sole responsibility for the correct interpretation of this report and the correct use of its accompanying data sets in environmental documents. The northern Sierra Nevada foothills wildlife connectivity project linkage data delineates lands likely important to the 30 focal species movement between large, mostly protected areas across the study area. It is a decision-support tool to be refined by field work and local linkage designs. DO NOT assume that lands outside Landscape Blocks or Least-Cost Corridors or Linkages are unimportant to wildlife populations or movements California Department of Fish and Wildlife, Data and Technology Division, Biogeographic Data Branch Melanie Gogol-Prokurat Conservation Analysis Unit Coordinator 916-324-9265 Melanie.Gogol-Prokurat@Wildlife.ca.gov Northern Sierra Nevada foothills wildlife connectivity team, California Protected Areas Database (CPAD - www.calands.org), National Conservation Easement Database (NCED - http://www.conservationeasement.us/), California Essential Habitat Connectivity Project (CDFW BIOS ds621).
