The national parks within the U.S. are wonders to behold. They haven’t been named “America’s Best Idea” for nothing. And while they may simply seem like places to vacation, they are much, much more than that. Beyond their pristine beauty, where you can find peace and adventure, they are home to some extraordinary species, including some animals on the endangered species list.
The National Park Service (NPS) staff, including rangers and researchers, work tirelessly to ensure these animals have a safe and thriving home to live in. However, their jobs have just become a little harder, and combined with a changing climate, it’s possible these animals could be even more threatened.
1. Kemp’s Ridley Sea Turtles
Not only are Kemp’s ridleys the smallest sea turtle species, but they’re also the most endangered. These turtles are often caught as bycatch in commercial fishing nets and, during the 1940s to the 1960s, were often harvested for their meat and skin. Poachers also raided their nests for eggs.
At one point, there were over 40,000 nesting females, but by the 1980s, that number had dipped to 300. The NPS, along with the National Oceanic and Atmospheric Administration (NOAA), worked hard to help preserve nesting beaches and sea turtle habitats. Their numbers are still low, under 6,000 nesting females, but they are seeing a rebound.

2. Indiana and Northern Long-Eared Bats
Some bat species that live around the Great Lakes Region, such as the Indiana bat (Myotis sodalis) and the northern long-eared bat (Myotis septentrionalis), are classified as endangered. They may live near national park sites like Indiana Dunes National Park and the Apostle Islands National Lakeshore, among others.
At the moment, bats are experiencing white nose syndrome (WNS), a highly infectious fungus that can bring bats out of hibernation and damage their wings. The NPS works to monitor bat populations and inform visitors about the spread of WNS to help keep them safe.
3. Black Footed Ferret
In 1980, it was believed that the black footed ferret had gone extinct. However, there were a few survivors still residing in Badlands National Park.
The ferret population has been greatly impacted by disease, and with so few survivors, researchers decided to capture the remaining wild ferrets and bred them in captivity. The population went from 18 ferrets in the late '80s to about 3,000 now. You can find wild ferrets running around the Badlands National Park today.
4. Sierra Nevada Bighorn Sheep
The Sierra Nevada bighorn sheep is an iconic symbol of the Sierra Nevada region and a subspecies of traditional bighorn sheep. During the gold rush of the late 1800s, these sheep were exposed to diseases from flocks of domestic livestock brought in by miners. Soon, the population began to dwindle.
By the late 1970s, only about 250 individuals remained. During the 1980s, the NPS, along with the Sierra Nevada Bighorn Sheep Interagency Advisory Group (SNBSIAG), helped grow the population and reintroduce herds to Yosemite National Park.
5. Desert Pupfish
The desert seems like an odd place for fish to live, but it’s precisely where the desert pupfish calls home. In Devil’s Hole, a water-filled cavern in Death Valley National Park, researchers discovered the pupfish. This little fish thrives in the salinated waters of Devil's Hole and eats the algae that grows there.
Every year, NPS researchers do a fish count. The average population is about 300 fish; however, in 2013, the population dipped to about 90, though researchers are not sure why. The NPS had been monitoring the waters constantly, and the 2024 count found that there were about 200 fish in Devil’s Hole.
These aren’t the only species that NPS and other agencies like NOAA protect. These incredible animals call the parks their homes, and if we’re lucky enough, while visiting the parks, we may even get to see them.
