Large Mammals
Bighorn Sheep
The impressive horns of the ram are well-known and are used to battle other males for breeding rights. These agile animals are well adapted for scrambling up and down mountains to elude predators and find food. Bighorn Sheep are considered good indicators of land health due to the species sensitivity to human caused problems. If sheep are thriving in an area the overall picture of the land is good. The land near Theodore Roosevelt National Park in western North Dakota is a good place to see these animals in the wild.
