25 C.F.R. § 243.12
Only the titles to Alaskan reindeer retained for research projects, or possessed by non-Natives under Special Use Permits for Public Display, or the titles to any Alaskan reindeer which may be acquired by the Government in the future for purposes of reestablishing a reindeer loan program, are held by the United States in trust for Alaska Natives. Other Alaskan reindeer are the private property of the Alaska Native owners. However, a trust responsibility continues to exist with respect to all Alaskan reindeer, insofar as the Government remains responsible for carrying out the provisions of the Reindeer Act and these regulations, including the provisions requiring approval of transfers to non-Natives, and providing for the determination of inheritance.
