Thoughtful Thursday: The Endangered Species Act Turns 40

The Endangered Species Act (ESA) was enacted by Congress in December of 1973. Its goal is to provide protection for species that are endangered or threatened and conserve the habitats their survival depends upon.

A species is considered endangered if it is in danger of extinction throughout all or significant portion of its range and threatened if it is likely to become an endangered species in the near future. Currently, there are over 2,000 species listed under the ESA. The efforts to protect these animals are administered by two federal agencies: the US Fish and Wildlife Service and the National Oceanic and Atmospheric Administration.

Zoos and Aquariums, including the National Aquarium, work closely with these agencies to both conserve habitats and raise public awareness of these species. Their continued survival is a large part of our organization’s mission. Here are just a few of the threatened/endangered species that call the Aquarium home:

In the last few decades, the Act has successfully prevented the extinction of 99 percent of the species it protects – making it one of the most effective conservation laws in our nation’s history! Check out this video looking back on the last 40 years of the ESA:

While there are many successes we should be celebrating today, there’s still a lot of work to be done in protecting species from decline and inspiring our next generation of conservationists.

Here’s how YOU can support our efforts to conserve and protect these amazing animals!

Sawfish Granted Endangered Species Protection

Earlier this month, the National Marine Fisheries Services granted sawfish protection under the Endangered Species Act (ESA).

Sawfish are one of the most, if not the most, imperiled groups of cartilaginous fish. Like most sharks and rays,  late maturity and low reproduction rates make these animals vulnerable to over-exploitation. Additionally, their toothed “saw” often gets caught in fishing gear and nets, making them susceptible to bycatch. As a result of these threats, populations of sawfish have reportedly declined by as much as 99 percent in recent decades.

All seven recognized species of sawfish are considered critically endangered by the International Union for Conservation of Nature (IUCN).  Nationally however, earlier petitions to grant sawfish similar protection under the ESA have not been successful. The first listing, of the smalltooth sawfish, occured in April of 2003. The largetooth sawfish was listed under the ESA in August of 2011. With the freshwater and largetooth species recently being synonymized, all are now protected under the ESA, including the two living here at the Aquarium.

The designation to list all species of sawfish is a positive step forward for these animals. The hope is that through collaboration with other aquariums, research biologists, conservation groups and NGOs we can assist in the recovery of sawfish populations worldwide.
