We may exclude any area from critical habitat if we determine that the benefits of such exclusion outweigh the benefits of specifying the area as part of critical habitat. We cannot exclude areas from critical habitat if such exclusion would result in the extinction of the species. Q. Does this economic analysis have any effect on the decision to list a species? A.
