National

NOAA Fisheries helps federal agencies comply with the requirements of the Endangered Species Act whose purpose is to conserve ecosystems upon which endangered and threatened species depend. NOAA Fisheries' Office of Protected Resources issues biological opinions to document our opinions on how federal agencies’ actions affect ESA-listed species and designated critical habitat.

How to Locate a Consultation

Biological opinions issued within the last five years are linked below by action agency. Opinions for pesticide consultations with the U.S. Environmental Protection Agency are listed separately, on our Pesticide Consultations page.

The Environmental Consultation System (ECO) is available to search ESA Section 7 consultations from 2017 to present.

Biological opinions issued since 2010 may also be found in the NOAA library repository.

If you are looking for a biological opinion from an ESA Section 7 consultation completed before 2019 that is not available in ECO, you may send an email with specific details on your request to NMFS.Historic.Consultations@noaa.gov.

Biological opinions are issued by our regional offices as well.
