George Bird Grinnell was an American anthropologist, historian, naturalist, and writer. Originally specializing in zoology, he became a prominent early conservationist and student of Native American life. Grinnell has been recognized for his influence on public opinion and work on legislation to preserve the American bison. Mount Grinnell in Glacier National Park in Montana is named after him.

The conservation movement, also known as nature conservation, is a political, environmental, and social movement that seeks to manage and protect natural resources, including animal, fungus, and plant species as well as their habitat for the future. Conservationists are concerned with leaving the environment in a better state than the condition they found it in. Evidence-based conservation seeks to use high quality scientific evidence to make conservation efforts more effective.
