NSNF-Landscape Blocks - CDFW [ds1004]

The northern Sierra Nevada foothills (NSNF) wildlife connectivity project modeled connectivity by identifying corridors for potential wildlife movement between habitat areas called landscape blocks. 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].
