Endangered Species Act

Defenders in Action

Championing the ESA
Defenders is the leading national conservation voice for the Endangered Species Act (ESA) and the protection and enhancement of a strong ESA is Defenders’ highest organizational priority.  We champion efforts to ensure that the ESA is allowed to accomplish what it was intended to do: to prevent the extinction of listed species and to promote their stabilization and recovery.

Improving the ESA
Our team of scientists, lawyers, policy experts and lobbyists focus on improving ESA policies, regulations, and guidance, so that they result in real-world benefits to imperiled species.  We also look for ways to make ESA policies more efficient, helping limited conservation dollars go farther, and making it easier for the public to comply with ESA regulations.

They came because conservation groups like Defenders saw the government was failing to comply with the law and used the tool of last resort: the courts.
