Science and Collaboration for Connected Wildlands 20130801 raster digital data ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/800_899/ds825.zip http://bios.dfg.ca.gov/ This dataset represents potential cores and patches of breeding habitat for American badger (taxidea taxus). Potential breeding area is defined as a cluster of pixels that are good enough (habitat suitability score above 50) and big enough to support breeding by the focal species. The other primary input to the analysis is home range or territory size. Thus, this analysis was only conducted if this information was available for the focal species. Potential breeding habitat was classified into two size classes. A potential core was defined as a continuous area of suitable habitat large enough to sustain at least 50 individuals. Potential cores are probably capable of supporting the species for several generations (although with erosion of genetic material if isolated). A breeding patch was defined as an area of suitable habitat large enough to support successful reproduction by a pair of individuals (perhaps more if home ranges overlap greatly), but smaller than a potential core area. Patches are useful to the species if the patches are linked via dispersal to other patches and core areas. For more information about the creation and utilization of this data, please see the report "A Linkage Network for the California Deserts" at http://www.scwildlands.org/reports/Default.aspx The primary objective of this effort is to identify lands essential to maintain or restore functional connectivity among wildlands for all species or ecological processes of interest in the California deserts and as a vital adaptation strategy to conserve biodiversity during climate change. Core areas capable of supporting 50 American badger (taxidea taxus) are equal to or greater than 16,000 ha (39,537 ac). Patch size is equal to or greater than 400 ha (988 ac) but less than 16,000 ha.

ESRI Sequential unique whole numbers that are automatically generated. Value The habitat suitability score, which is calculated as a function of pixel attributes such as land cover, road density, topographic position, and elevation. Count The number of cells that contain the habitat suitability value. Habitat The potential breeding area, defined as a cluster of pixels that are good enough and big enough (i.e., larger than minimum sizes specified by the species expert) to support breeding by the focal species. core A contiguous area of suitable habitat large enough to sustain at least 50 individuals. Potential cores are probably capable of supporting the species for several generations (although with erosion of genetic material if isolated). patch An area of suitable habitat large enough to support successful reproduction by a pair or individuals (perhaps more if home ranges overlap greatly), but smaller than a potential core area. Patches are useful to the species if the patches are linked via dispersal to other patches and core areas. < patch (less than patch) Areas of suitable habitat that are smaller than a breeding patch. 20160902 Science & Collaboration for Connected Wildlands Kristeen Penrod Conservation Director (209)285-1916 kristeen@scwildlands FGDC Content Standard for Digital Geospatial Metadata FGDC-STD-001-1998 local time
