Do you love watching the wolves of Yellowstone? How can you keep track of them - get your wolf chart! The color-coded system tracks the geneology of wolves and relationships between packs.
Each known wolf is represented and radio-collared wolves(numbered) are shown. A map of the Yellowstone National Park shows the location of each wolf pack or group.
The chart represents the biological success of the preceeding year by showing those wolves that have survived since last year's pup season.
Each four-color chart is laminated in a protective plastic sheet for improved clarity and field use.
