The CSS conducts basic and applied research, especially in the fields of reproductive science and animal management, to understand biological mysteries and to implement practical solutions to help rare species survive. The priority is to avoid extinction while creating methods to sustain viable wildlife populations—for zoos and in the wild.

CSS researchers use multidisciplinary approaches and modern tools to integrate new information in order to quickly stabilize and recover endangered animal populations. They work with a worldwide network of collaborators from conservation organizations, universities, zoos, and governmental agencies, and their efforts extend far beyond the physical boundaries of the Smithsonian Institution and National Zoological Park.

Reproductive Science Research Programs

Reproduction and Reintroduction of Antelopes and Cervids

scimitar-horned oryx

The Zoo's Reproduction and Reintroduction of Desert Antelope project uses advances in the reproductive sciences to enhance the genetic management of antelope, and to reintroduce herds of these rare species to their native range in North Africa. Learn more.

Coral Reef Conservation with Modern Fertility Techniques

coral

SCBI scientists are using modern fertility techniques to preserve the world's coral reef species. Learn more.

Black-footed Ferrets

black-footed ferrets

The National Zoo's Black-Footed Ferret Reproduction Project studies the biology of the black-footed ferret to enhance reproduction, maintain genetic diversity, and provide animals for reintroduction to the western Great Plains. Learn more

Improving Elephant Reproduction

Asian elephant

The National Zoo’s Elephant Reproduction Project and its associated Endocrine Lab, led by National Zoo scientist Janine Brown, studies the biology of elephants through basic and applied research to enhance species conservation and management. Learn more

Conservation of Rare Felids

clouded leopard

The National Zoo’s Cat Conservation Project studies reproduction of cats to create scholarly knowledge and to facilitate management and conservation of cheetahs, clouded leopards, and fishing cats. Learn more

Conservation of Rare Canids

maned wolf

Zoo scientists study the reproduction and ecology of rare canids, including maned wolves from South America, dholes from Asia and, African wild dogs.

Reproduction in Wild Equids

Przewalski's horses

The Zoo is one of the leaders in wild equid reproduction, including Przewalski's horses, Grevy's zebras, and Persian onagers. Learn more

Genome Resource Banking for Global Conservation

The National Zoo maintains a valuable living repository of specimens from rare and endangered species in the Genome Resource Bank to support efforts in biodiversity and species conservation. Learn more

Monitoring Hormones for Well-Being and Reproduction

The National Zoo's Endocrine Research Laboratory evaluates hormones to enhance reproduction and animal well-being of wildlife living in zoos and in nature. Learn more

Endangered Species Research Programs

Amphibian Conservation Program

Panamanian golden frog

Scientists at the Zoo work to understand, and halt, the unprecedented decline of amphibian populations. Learn more

Eld's Deer

Eld's deer

These magnificent deer only persist in surviving pockets in Asia, where once they roamed all over.

White-Naped Cranes

white-naped crane and chick

Zoo scientists work to conserve these beautiful birds through captive breeding and research. Through artificial insemination, the zoo has added vital genetic diversity to the captive flock by producing offspring from cranes previously unable to breed. Learn more

Micronesian Kingfisher

Micronesian kingfisher

These endangered birds are difficult to breed in captivity. Zoo scientists are working to figure out why. Learn more

Red Pandas
