In an effort to consolidate, regulate, and control Indian land holdings, the financially self-sustaining Yakama Nation Land Enterprise has successfully acquired more than 90% of all the fee lands within the Nation’s closed area — lands which were previously highly "checker-boarded." The Enterprise’s land purchase program has allowed the Nation to expand industrial, business, and agricultural activities; tracts of land are used for housing, day care centers, ranger stations, longhouses, and for use by tribal education, foods, resource management, and cultural programs.
