Section 7 Consultation Issued Biological Opinions

Technology: Pull Reports / REST

When a Federal agency determines, through a biological assessment or other review, that its action is likely to adversely affect a listed species, the agency submits to the Service a request for formal consultation. During formal consultation, the Service and the agency share information about the proposed project and the species likely to be affected. Formal consultation may last up to 90 days, after which the Service will prepare a biological opinion on whether the proposed activity will jeopardize the continued existence of a listed species. The Service has 45 days after completion of formal consultation to write the opinion.
