Why the stamp was issued:  To commemorate the 50^th anniversary of the Endangered Species Act and the endangered Nashville crayfish.

About the stamp design:  Like the others in the set, the photograph on the stamp is from Joel Sartore’s famous “Photo Ark” project.  They are among over 13,000 the National Geographic photographer has taken in his quest to shoot photos of as many animal species as possible.

Special design details:  Stamp includes “Endangered” and the common name of the species.

First Day City:  First Day of Issue Ceremony was in Wall, South Dakota, at the National Grasslands Visitor Center.  The center encourages visitors to see the 20 National Grasslands and Midewin National Tallgrass Prairie.  These habitats are home to the black-footed ferret, one of the endangered species pictured in the set of stamps.

About the Endangered Species set:  The Endangered Species Act of 1973 (ESA) was signed into law by President Richard Nixon on December 28.  The legislation “protect[s] species and the ecosystems upon which they depend,” with a goal “to halt and reverse the trend toward species extinction, whatever the cost.”  The ESA is jointly administered by the United States Fish and Wildlife Service and National Marine Fisheries Service.

In 2023, the US Postal Service celebrated the 50^th anniversary of the ESA with a set of 20 Forever stamps.  The stamps were issued on Endangered Species Day, which lands on the third Friday in May.  Each design pictures a different endangered species, representing only a small handful of the over 1,300 plants and animals protected under the ESA as of 2023.  The images used for the stamps were part of Joel Sartore’s “Photo Ark.”  Partnering with National Geographic, he set out to capture 20,000 species living in zoos and wildlife sanctuaries around the world.  Together, they are determined to intimately picture each species in order to educate and bring awareness to their preservation.  Sartore calls his work as a photographer a “mission to document endangered species and landscapes in order to show a world worth saving.”

Thanks to the ESA, many plant and animal species that were once endangered have made a comeback.  With the continued effort of conservationists, volunteers, and increased awareness, even more species can make their way back from the brink of extinction one day.

History the stamp represents:  The Nashville crayfish (Faxonius shoupi) (previously known as Orconectes shoupi) is a freshwater crustacean mainly found in the Mill Creek Basin of Nashville, Tennessee.  The species has been in decline for several decades, facing obstacles such as water pollution, restricted range, and competition with invasive crayfish species.  It was listed endangered on September 26, 1986, with just a third of the number of individuals that were counted in 1969.

Nashville crayfish are orange and black with four pairs of legs, two red-tipped pinchers, and a lighter saddle on their backs and sides of their heads.  They grow to lengths of up to seven inches and are fairly aggressive, chasing opponents away or even cornering them.  The crayfish eat algae, insects, worms, snails, fish eggs, leaves, and mussels.  They reproduce in late summer and early fall, with females laying eggs in late winter and early spring.

While the species is still endangered, the US Fish and Wildlife Service suggested it has recovered to the point where it may be suitable for downgrading to “threatened.”  The population of Nashville crayfish has stabilized over the last 20 years and it is believed that they have become more resistant to changes in their environment.  If only all endangered species could be so lucky!
