Designing Corridors – GIS Toolkit
The folks at CorridorDesign.org say it best “Our goal is to transfer everything we’ve learned about designing wildlife corridors to the public to facilitate better conservation, science, and dialogue.” The site includes examples, how-tos, white papers and – best-of-all – dozens of ArcGIS extensions. All free. Developed for Arizona, no doubt they could be adapted for anywhere. See the scientific publication in Conservation Biology. You could make an entire graduate seminar course out of this website!!
