Detailed Description

Challenge of Making Economic Estimates for Biodiversity

by Alicia Torregrosa, Geographer and Ecologist


  • How can we best strike a balance between vineyard development and wildlife in the Napa Valley?
  • Geographic Information System (GIS) facilitates comparing the "apples and oranges" of endangered species and the value of real estate
  • Linking GIS layers and models gives them added meaning and value
  • Such data layers are part of biodiversity software being developed by NatureServe
  • This software will help decisionmakers evaluate alternative land-use choices
