50th Anniversary of the Endangered Species Act with smalltooth sawfish, green turtle, Atlantic salmon, staghorn, North Atlantic right whale, and Tubastraea floreana

Join us in celebrating the 50th anniversary of the Endangered Species Act, May 19–December 28, 2023! This landmark legislation is a powerful and effective tool for conserving species and their habitats.

Under the Act, NOAA Fisheries is responsible for the protection, conservation, and recovery of more than 160 endangered and threatened marine and anadromous species . At NOAA Fisheries, we rely on the best available science to implement the ESA . During this monumental commemoration of 50 years, we highlight our science, conservation, partnerships, and people who implement the ESA through the features and videos below.

Follow along on our NOAA Fisheries social media channels and stay tuned for more content.

Species in the Spotlight

Of all the species NOAA Fisheries protects under the Endangered Species Act, we consider nine among the most at risk of extinction in the near future.

Endangered Species Conservation

To implement the Endangered Species Act, we rely on the best available science. We work with international federal, tribal, state, and local agencies, as well as nongovernmental organizations and private citizens.

The Endangered Species Act continues to be a powerful and effective tool for conserving species and their habitats. Less than 1 percent of the species listed under the ESA have gone extinct. Others have been recovered to the point where they no longer need protections under the ESA.
