Finally, we note two ways in which our decision is limited. First, we hold that Bighorn National Forest is not categorically occupied, not that all areas within the forest are unoccupied. On remand, the State may argue that the specific site where Herrera hunted elk was used in such a way that it was “occupied” within the meaning of the 1868 Treaty. See State v. Cutler, 109 Idaho 448, 451, 708 P. 2d 853, 856 (1985) (stating that the Federal Government may not be foreclosed from using land in such a way that the Indians would have considered it occupied).

Second, the state trial court decided that Wyoming could regulate the exercise of the 1868 Treaty right “in the interest of conservation.” Nos. CT–2015–2687, CT–2015–2688, App. to Pet. for Cert. 39–41; see Antoine, 420 U. S., at 207. The appellate court did not reach this issue. No. 2016–242, App. to Pet. for Cert. 14, n. 3. On remand, the State may press its arguments as to why the application of state conservation regulations to Crow Tribe members exercising the 1868 Treaty right is necessary for conservation. We do not pass on the viability of those arguments today.
