The Chesapeake Bay Field Office is responsible for protecting threatened and endangered species and conserving at-risk species in Delaware, the District of Columbia, and Maryland. We work with other Federal agencies, state and local governments, Native American tribes, conservation organizations, and private citizens to recover these species. At-risk species are those that are: already proposed but not finalized for listing under the Endangered Species Act (ESA); candidates for listing under the ESA; or petitioned for listing under the ESA. At-risk species conservation is preventative medicine. By helping at-risk wildlife and plants early on, we can prevent the need for Federal protection.
