Protecting Imperiled Species

Holding Everyone Accountable

Holding Everyone Accountable

Our Conservation Law department works with other conservation organizations, wildlife scientists and experts, and federal agencies to make sure that endangered species receive the full protection they deserve.

When a federal agency proposes an action that is likely to jeopardize an endangered species or damage its critical habitat, our legal team goes to court to stop it. If the administration inappropriately fails to protect an imperiled species under the ESA, we challenge it. Over the past 30 years, Defenders has filed numerous lawsuits to protect a wide variety of endangered species, from our ongoing role defending wolves, to advocating for increased protections for polar bears and sea turtles. We are also always there to hold people, organizations, corporations, or agencies accountable should they ever break laws protecting imperiled species.
