As part of the 2009 settlement of the "Cobell v. Salazar" class-action suit, the Department of Interior has set up the Land Buy-Back Program for Tribal Nations to buy back such fractionated land from descendants, on a purely voluntary basis, with market value being offered. The land portions of those who accept the offers will be put in federal trust under control of the tribe, so it can increase the communal land base and improve its ability to manage resources for its members. In 2015, "than 3,500 buy-back offers were mailed to tribal landowners at the beginning of June. Some amounted to less than $100, others total tens or even hundreds of thousands [of dollars." In June 2015, Interior employees came to the reservation to discuss the program in more detail. They reviewed up to $54 million in offers with landowners who may be interested in selling their portions. These offers apply to 26,000 tracts of land, most very small, within the boundaries of the Fort Belknap reservation.
