North Carolina’s federally threatened, endangered, and at-risk plant species
Optimal survey windows and duration a survey is valid

These survey windows were determined using information from species recovery plans, field observations, herbaria specimens, and NC Natural Heritage Program information. If suitable habitat for species is present in the proposed impact area, the U.S. Fish and Wildlife Service will likely request species surveys, conducted by a qualified biologist, during the optimal survey window. Projects are reviewed on a case-by-case basis and you are encouraged to contact a Section 7 Section 7
Section 7 Consultation The Endangered Species Act (ESA) directs all Federal agencies to work to conserve endangered and threatened species and to use their authorities to further the purposes of the Act. Section 7 of the Act, called "Interagency Cooperation," is the mechanism by which Federal agencies ensure the actions they take, including those they fund or authorize, do not jeopardize the existence of any listed species.
