It would have been helpful if the article provided a bill number. I believe they are referring to Senate Bill 3014 “Tribal Forestry Participation and Protection Act of 2016”

My concern with the bill is that it would give Indians control over already scarce water in the green river basin and various other basins in colorado, new mexico, utah nevada wyoming and idaho where a lot oil and natural gas would be extracted in a trump administration.
Judging by what you have seen is this concern founded or unfounded.
