Yellowstone Wolf Project Reports

STUDENTS & RESEARCHERS: The National Park Service wolf territory GIS files are now available on-line for download. The data is public domain, however we do appreciate NPS credit for it's use. These are the same shape files that we use in creating our annual report maps. The files are .MCP (minimum convex polygon) files. WOLF TERRITORY GIS DATA
