Ecuador’s Yasuni National Park

Explore the vast natural riches of one the most bio diverse places on earth.

Yasuni National Park in Ecuador is reputed to be the biologically richest place on earth. Its 3791 square miles are believed to contain more species of plants and animals than any other comparable area.

These photos were taken by award-winning nature photographer Peter Oxford and first appeared in "Yasuni, Tiputini & the Web of Life," a book he co-authored with Dr. Kelly Swing. Pete is a biologist who was named one of the 40 most influential nature photographers by Outdoor Photography magazine. His photo credits include National Geographic, Smithsonian, and International Wildlife. A founding member of the International League of Conservation Photographers (ICLP), Pete works as a team with his long-time partner and wife Renee Bish, with whom he has published eight books, two of which focus entirely on the Galapagos Islands. ©Pete Oxford /
