This essentially treats the Native tribes as similar to those in the lower 48- the feds control the land in trust for the tribes. While  this increases federal holdings in the state(from 69% to 79%) , and will likely lead to increased protections in some areas, ultimately this will not harm the state. Alaska should drop the challenge, they are not going to win in either instance, whether challenging in district court, or challenging the holding of Native lands in trust.
