Endangered Species


Protecting Endangered Species
The U.S. Fish and Wildlife Services provides national leadership in the recovery and conservation of our nation's imperiled plant and animal species, working with experts in the scientific community to identify species on the verge of extinction and to build their road to recovery. We work with a range of public and private partners to protect important habitat, increase species' populations and reduce the threats to their survival so that they can be removed from federal protection.
What we Do
Our work to conserve and recover endangered and threatened species includes listing species under the Endangered Species Act (ESA) and designating critical habitat, developing protective regulations for threatened species, developing and implementing recovery plans for listed species, monitoring and evaluating the status of listed species, and, cooperating with non-federal partners to develop conservation plans.




Working With Partners
For 50 years, the ESA has prevented the probable extinction of hundreds of species across the nation and contributed to the recovery of many others. Additionally, other efforts using the Service's ESA tools have contributed to improving the status of unlisted or candidate species. Landowners – including private citizens, tribes, conservation organizations, businesses, state and local agencies, other federal agencies – have all contributed to these efforts.
The ESA provides a broad and flexible framework to facilitate conservation with a variety of stakeholders. We have a number tools to help our agency work with, leverage, and expand our existing network of conservation partnerships to produce effective conservation practices and conservation strategies on the ground.














Species Status Assessment
The Species Status Assessment framework is an analytical approach developed by the U.S. Fish & Wildlife Service to deliver foundational science for informing all Endangered Species Act (ESA) decisions. An SSA is a focused, repeatable, and rigorous scientific assessment. The result will be better assessments, improved and more transparent and defensible decision making, and clearer and more concise documents. The Service is already seeing benefits from this approach.
