Joel Sartore’s Photo Ark: 18,000 species documented to save wildlife

Photographer Joel Sartore has dedicated two decades to documenting wildlife through his Photo Ark project, which began in 2006. The ambitious endeavor aims to photograph every species on Earth before they disappear, creating a visual record for future generations. Starting with a naked mole rat at Lincoln Children's Zoo in Nebraska, Sartore's project has expanded into a global conservation effort, with over 18,000 animal images now in the collection.

The project's origins stem from a personal crisis in Sartore's life when his wife was diagnosed with breast cancer. Drawing inspiration from naturalist John James Audubon's work, Sartore envisioned a modern-day record of animals that might otherwise vanish. This personal struggle propelled the project into his life's work, with a focus on documenting obscure and lesser-known species, not just the famous ones like tigers or polar bears.

Sartore has faced the race against extinction with the Photo Ark, as many of the photographed animals are on the brink of disappearing. One striking example is Toughie, the last known member of the Panamanian tree frog species, which succumbed to the chytrid fungus. This photo serves as a poignant reminder of the urgency behind the project. Similarly, the Florida grasshopper sparrow's plight was highlighted by Sartore's photos, leading to greater awareness and funding for its conservation.

Collaboration is the key to the Photo Ark's success, with a vast network of conservationists, zoos, researchers, and photographers supporting Sartore's work. His family has also played crucial roles, with his son Cole contributing technical skills and his wife managing the logistical aspects. The team's efforts have taken them to more than 100 locations, including a 2026 expedition to Australia, where they photographed a variety of species.

While the Photo Ark has documented more than 18,000 species, Sartore acknowledges that there is still a long road ahead. Some endangered animals remain elusive, requiring extensive negotiations and conservation efforts before they can be photographed. However, the project has also captured stories of rediscovery and recovery, such as the Lord Howe Island stick insect and the Florida bonneted bat.

These instances demonstrate that conservation efforts can sometimes provide a second chance for species on the brink of extinction.

Ultimately, Sartore's goal with the Photo Ark is to shed light on the reality of extinction and inspire public interest, funding, and political support for conservation. By making endangered animals visible through his striking studio portraits, Sartore hopes to generate the necessary attention and resources to protect these species before they are lost forever.
