Know what supports the claim.

An independent curated reference to USDA regional native status and state presence, unaffiliated with USDA or ASPCA.

USDA provides native status by region and presence by state. A state presence record does not establish state nativity. This collection includes profiles with Region L48 Status N. DC uses the Lower 48 status. Alaska and Hawaii require their own regional Native status; territories are outside this collection.
