We hope you will enjoy learning about the exciting ecosystems and species we are studying throughout the United States. Our scientists work within the Rocky Mountain regions of Montana, Wyoming, and northern Idaho, which include the diverse Greater Yellowstone and Northern Continental Divide ecosystems. We also study a variety of topics throughout the U.S. Browse our feature articles or dive right into the science by reading about ongoing research projects or publications our scientists have produced.
