10 . Brief for Petitioner 25. (Habitat can, of course, include areas where the species does not currently live, given that the statute defines critical habitat to include unoccupied areas.) The Service in turn disputes Weyerhaeuser’s premise that the administrative record shows that the frog could not survive in Unit 1. Brief for Federal Respondents 22, n. 4.

The Court of Appeals concluded that “critical habitat” designations under the statute were not limited to areas that qualified as habitat. See 827 F. 3d, at 468 (“There is no habitability requirement in the text of the ESA or the implementing regulations.”). The court therefore had no occasion to interpret the term “habitat” in Section 4(a)(3)(A)(i) or to assess the Service’s administrative findings regarding Unit 1. Accordingly, we vacate the judgment below and remand to the Court of Appeals to consider these questions in the first instance.

Weyerhaeuser also contends that, even if Unit 1 could be properly classified as critical habitat for the dusky gopher frog, the Service should have excluded it from designation under Section 4(b)(2) of the ESA. That provision requires the Secretary to “tak[e] into consideration the economic impact… of specifying any particular area as critical habitat” and authorizes him to “exclude any area from critical habitat if he determines that the benefits of such exclusion outweigh the benefits of specifying such area as part of the critical habitat.” 16 U.
