Alaska's western Arctic encompasses a vast, wild stretch of land called the National Petroleum Reserve – Alaska. At 23 million acres it is the largest single unit of public land in the nation. That's about the same size as the entire state of Indiana!

When you hear the name, National Petroleum Reserve – Alaska (NPR-A, or Reserve), you might think of a barren land filled with oil wells and industrial equipment, but the vast majority of the Reserve actually remains free of industrial development and provides necessary habitats and resources for an incredible array of wildlife and indigenous peoples who have lived and thrived in this landscape since time immemorial. 

Defenders of Wildlife's new ArcGIS Storymap illustrates why the NPR-A is important to wildlife.
