25 endangered animals that only live in America
The Endangered Species Act is a landmark conservation law that has brought wildlife threatened by habitat destruction, climate change, and other issues back from the brink of extinction; the iconic Bald Eagle is one of the most well-known examples.
In 2019, the Trump Administration rolled back several major protections outlined in the Endangered Species Act. These changes included banning blanket protections for newly threatened species and allowing cost to be a consideration when evaluating what it would take to save at-risk species. While in office, Trump took more than 100 legislative actions favoring business over the environment. In July 2022, U.S. District Judge Jon Tigar, presiding in Northern California, threw out the Trump-era changes, restoring critical protections for threatened species.
More than 1,300 species in the U.S. are listed as either endangered or threatened under the Endangered Species Act. Some of these animals are found nowhere else in the world. Stacker compiled a list of 25 endangered animals that are only found in the United States using the 2022 International Union for Conservation of Nature Red List and the U.S. Fish and Wildlife Service Endangered Species list.
All animals on this list are classified as either Endangered or Critically Endangered by the IUCN and classified as either Endangered or Threatened by the federal government. While the U.S. Fish and Wildlife Service identifies critical habitats and provides legal protections for endangered species, the IUCN helps raise global awareness through data collection, analysis, fieldwork, advocacy, and fundraising.

Salt marsh harvest mouse
– Scientific name: Reithrodontomys raviventris
– Red List status: Endangered
– Geographic range: California
The salt marsh harvest mouse was found around the Bay Area until relatively recently, but its habitat has become extremely fragmented. Because of human development, populations of the mouse are isolated from one another and cannot breed properly.

Utah prairie dog
– Scientific name: Cynomys parvidens
– Red List status: Endangered
– Geographic range: Utah
The Utah prairie dog was declared endangered in 1973. However, over the last 30 years, the population has been stable to increasing, and the species is now federally recognized as threatened rather than endangered. Threats like urban expansion, climate change, and resource exploration remain, but the prairie dog has recovered strongly.

Red wolf
– Scientific name: Canis rufus
– Red List status: Critically endangered
– Geographic range: North Carolina
Red wolves were once found along much of the Southeast, but habitat destruction, hunting, and urban encroachment have dwindled their range to the point that they are now only found in North Carolina. They’re one of the most endangered canids on Earth. Red wolves are also highly endangered because of interactions with coyotes, which can hurt the species’ long-term viability.

Kauai cave wolf spider
– Scientific name: Adelocosa anops
– Red List status: Endangered
– Geographic range: Hawaii
The Kauai cave wolf spider is a highly unusual spider found only in caves in the Koloa district of Kauai, Hawaii. Wolf spiders usually utilize their vision rather than webs to catch prey; however, the Kauai cave wolf spider is unique because it is eyeless, relying only on swift motion to hunt. Because they have such specific habitat needs, these spiders are highly vulnerable to habitat destruction from construction, human visitation, and other sources.

Giant kangaroo rat
– Scientific name: Dipodomys ingens
– Red List status: Endangered
– Geographic range: California
Giant kangaroo rats are the largest species in their family. They got their name because they stand up on their hind feet and hop to move, much like a kangaroo. They create complex burrow systems that sometimes have more than five separate entrances. In addition to habitat fragmentation, this species is under threat from rodenticide use in agricultural operations.

Delta green ground beetle
– Scientific name: Elaphrus viridis
– Red List status: Critically endangered
– Geographic range: California
This beetle has a range of only about 7,000 acres in Solano County, California. There are natural gas reserves in the beetle’s habitat, so natural gas exploration could further threaten it. Because it is unusually colorful, it could also be a target for illegal collectors.

Jollyville Plateau salamander
– Scientific name: Eurycea tonkawae
– Red List status: Endangered
– Geographic range: Texas
This unique salamander spends its entire life underwater. It was only discovered in 2000, but already its population has declined dramatically due to the sensitive nature of these amphibians. The Jollyville Plateau salamander is highly threatened by development, which groups like The Center for Biological Diversity fight in areas known to be inhabited by the species.

California condor
– Scientific name: Gymnogyps californianus
– Red List status: Critically endangered
– Geographic range: California, Arizona, Utah
Condors are the largest flying birds in North America. Their wingspan is nearly 10 feet from tip to tip. After they nearly went extinct, the remaining 10 wild condors were captured in 1987; reintroduction began in 1992. Although the condor population has grown to exceed 500 birds today, they’re still considered endangered.

American burying beetle
– Scientific name: Nicrophorus americanus
– Red List status: Critically endangered
– Geographic range: Arkansas, Kansas, Massachusetts, Nebraska, Ohio, Oklahoma, Rhode Island, South Dakota, Texas
Burying beetles survive off the carcasses of dead animals, which they bury in the ground. Biologists aren’t sure what has led to their rapid decline, but it is possible that it has been caused by declines in other species that they rely on to eat.

Northern Idaho ground squirrel
– Scientific name: Urocitellus brunneus
– Red List status: Endangered
– Geographic range: Idaho
This rare squirrel relies on large amounts of grass and seeds to fatten up for its long winter hibernation. Fire suppression efforts have greatly reduced its food supply, leading to population decline. While the species recovery pattern is largely unknown, an estimated 2,200 animals exist across 54 populations in Idaho.
