Endangered Species Act Section 7 Biological Opinions in the Southeast

Frequently Requested Biological Opinions

Under Section 7 of the Endangered Species Act, federal agencies must consult with NOAA Fisheries on activities that may affect ESA-listed species. These federal agency consultations are designed to help federal agencies in fulfilling their duty to ensure that their actions do not jeopardize the continued existence of a species, or destroy or adversely modify designated critical habitat.

NOAA Fisheries Southeast Regional Office, Protected Resources Division, issues Biological Opinions to document our Opinions on how federal agencies’ actions affect ESA-listed species and critical habitat in the Southeast. Where appropriate, these Opinions provide an exemption for the “take” of listed species (e.g., harassment, harm, pursuit, hunting, shooting, wounding, killing, trapping, capturing, or collecting) while specifying the extent of take allowed, the reasonable and prudent measures that would minimize impacts from the federal action, and the terms and conditions with which the federal action agency must comply.
