12/12/2008 Phase 1 � Focal species selection criteria � Focal species list � Public open space classification criteria � Public open space map � Land use classification and map � Land cover mapping process � Land cover map Habitat Modeling 5

12/12/2008 Focal Species Habitat Modeling � Models give a better indication of where species could occur based on habitat i ld b d h bit t characteristics � Will highlight areas where mitigation could occur for given species � Determine when species surveys are needed � Determine when species surveys are needed � Gives context to the regulatory agencies when they are reviewing a project Focal Species Habitat Modeling Use known life history information and available biotic and abiotic information to help biotic and abiotic information to help determine potential distribution: � Land-cover types � Soils � Elevation or slope characteristics � Known dispersal or movement distances for wildlife � Known dispersal or movement distances for wildlife � Specific habitat features (e.g., aquatic habitat) � Any other life history requirements that can be replicated in GIS � Use known occurrences to check potential distribution for accuracy. 6
