BIA AIAN Land Area Representations Map

Metadata Updated: September 11, 2025

For a detailed view of Alaska, please reference the BIA AIAN LAR (Alaska Detail) Map here: https://bia-geospatial.maps.arcgis.com/sharing/rest/content/items/c914b3914c97440f9e90d142be55a683/data. The purpose of the American Indian and Alaska Native Land Area Representation (AIAN-LAR) Geographic Information System (GIS) dataset is to depict the exterior extent of land held in “trust” or “restricted fee” status by the United States for a tribe(s) and individual Indians of federally recognized Tribes. A tribe is a tribe, band, pueblo, community or other federally acknowledged group of Indians. A federally recognized tribe is an American Indian or Alaska Native tribal entity that is recognized as having a government-to-government relationship with the United States, with the responsibilities, powers, limitations, and obligations attached to that designation, and are eligible for funding and services from the BIA. Furthermore, federally recognized tribes are recognized as possessing certain inherent rights of self-government (i.e., tribal sovereignty) and are entitled to receive certain federal benefits, services, and protections because of their special relationship with the United States. At present, there are 574 federally recognized American Indian and Alaska Native tribes and villages. Not all federally recognized Tribes have a designated land area, land in trust or restricted status and therefore may not have an associated land area represented in the AIAN-LAR. Not all land areas such as public domain allotments are under the jurisdiction or associated with any particular federally recognized tribe. The BIA publishes an updated list of federally recognized tribes in a federal register notice. These data are public information and may be used and interpreted by organizations, agencies, units of government, or other entities. The user, agency or organization has sole responsibility for ensuring the appropriate use, application, integration and republication of these data.
