We’re Back!

What do a green sea turtle and a Florida panther have in common? They are both protected by the Endangered Species Act (ESA). The law was passed in December 1973. The ESA makes it illegal to kill, capture, or harm any species listed as endangered. It protects the habitats where these plants and animals live. It also provides funding to help species recover. 

Today, more than 1,600 plants and animals are protected by the ESA. It has been called one of the world’s most successful conservation laws. About 99 percent of the species under its protection have been saved from extinction.

“There’s a long list of species that were in big-time decline that we brought back,” says Randy Robinson. He works at the U.S. Fish and Wildlife Service. That’s one of the groups that manages the ESA. 

Here’s a look at some of the ESA’s biggest success stories in the U.S.

More than 200 million years ago, alligators lived side by side with dinosaurs. Unlike dinos, alligators still roam Earth. But one species—the American alligator—was nearly wiped out by humans. By the 1960s, hunters had killed enough of these giant reptiles to put the species in danger. Alligator skin is used to make leather products, including shoes, belts, and bags. In 1973, the animals became one of the first species to be protected by the ESA.

Since 1987, they haven’t been considered endangered. But American alligators remain protected under the ESA. Why? A close relative, the American crocodile, is in danger of dying out. The two species look very similar. Officials worry that hunters could confuse alligators with crocodiles.

These mammals are the largest of all sea lions. They can weigh as much as 2,500 pounds. Steller sea lions feast on up to 35 pounds of salmon, cod, and other types of fish in a single meal! 

The animals’ huge appetite is one reason they were in danger of dying out. Fishermen often shot the hungry sea lions to prevent the animals from hurting their catch. By the late 1970s, only about 18,000 eastern Steller sea lions remained in the wild. 

In 1990, these sea lions were added to the endangered species list. Part of the ESA’s plan involved educating people about the animals. Twenty years later, the population had bounced back to more than 70,000. The eastern Steller sea lion was removed from the list in 2013.
