Studies in Landscape Analysis and Conservation Prioritization 
Historically, conservation of natural areas has been approached opportunistically (a piece of land came up for sale, or an area could be conserved without much opposition) or reactively (areas were conserved only after significant threat or imperilment). However, in order to be most effective with the limited resources available for conservation we need ways to identify those areas most in need of protection or that would make significant contributions to existing protected areas.

The following projects demonstrate the use PBI's use of Geographic Information System (GIS) analysis and design techniques to identify high-priority areas for conservation and direct conservation efforts.
