2023 Endangered Species Stamp Sheet - Forever - MNH

Nearly 50 years ago, the Endangered Species Act (ESA) was signed into law. Under the ESA, more than 1,670 U.S. and nearly 700 foreign species are safeguarded to increase their chances of survival. With the release of the new Endangered Species Forever stamps today, the Postal Service is celebrating not only the law, but also the people, organizations and agencies who have worked so hard to protect and save so much.

The 20 stamps showcase photographs of endangered animals found within the 50 states and American territories, as well as two North American species living near U.S. borders.

The photos were taken by National Geographic Explorer and photographer Joel Sartore as part of his National Geographic Photo Ark project, an effort to document every species living in the world’s zoos, aquariums and wildlife sanctuaries. Photo Ark also inspires action through education and helps protect wildlife by supporting on-the-ground conservation efforts.
