"Almost all the Crow Tribe's land is classified as irrigated dryland farm or grazing land. Most of it is leased to large, non-Indian interests, such as the Scott Land and Cattle Company or the First Continental Corporation. More than 7,000 agricultural leases exist on the Crow Reservation, of which some 4,000 are overseen by the Bureau of Indian Affairs through a land management program. The others are called 'competent' leases—leases that allottees can negotiate on their own, without approval of the Bureau of Indian Affairs. Once negotiated, the leases have to be filed with the BIA, but the Bureau has no say in their management. Competent leases are unique to the Crow tribe and complicate administration because there is no coherent land management system, despite the fact that reservation lands are divided into management units on paper. Approximately 1.2 million acres are leased as grazing land, with another 150,000 acres leased for dryland crops, primarily alfalfa and wheat. There are roughly 30,000 leased irrigated acres, owned by the tribe and allottees, mostly used to grow corn and sugar beets."
