The National Geographic Photo Ark is a compelling and visually powerful project that aims to photograph rare and endangered species before it is too late. In addition to creating an archival record for generations to come, this project is a hopeful platform for conservation and shines a light on individuals and organizations working to preserve species around the world.

Now National Geographic is showcasing this project in a traveling outdoor photo exhibition making its way to Woodland Park Zoo, Apr. 20 – Oct. 7, 2018. Featuring the work of National Geographic photographer and Fellow Joel Sartore, the exhibition will display more than 50 stunning animal portraits taken in the world’s best zoos and wildlife sanctuaries.

This exhibition is organized by the National Geographic Society and Omaha’s Henry Doorly Zoo and Aquarium. It is free with zoo admission or membership.
