Life in the Grand Canyon

There is a diverse population of life in the canyon, where over 1,500 plant, 500 types of animals are found, and insects abound (as you probably know if you've camped below the rim!) The canyon offers a nearly undisturbed natural habitat through a range of elevations from desert to mountain forests on the rims.

Around 450 Native Americans live in the canyon year-round in Supai, on the Havasupai Reservation. The Havasupai have lived in the canyon for hundreds of years. Traditionally they farmed the fertile soil in Cataract Canyon in the summer raising maize, squash, beans, and peaches. In the winter they hunted game on the rim for sustenance.
