The Tyonek Tribal Conservation District encompasses 6.6 million acres in the West Cook Inlet region. Our boundaries align with Game Management Unit 16B, bounded by the Alaska Range to the west, Cook Inlet to the east, the Susitna River to the north, and the Trading Bay area to the south.
This vast landscape includes wild salmon rivers, coastal estuaries, boreal forests, and sub-alpine habitat. TTCD works in partnership with the Native Village of Tyonek, Tyonek Native Corporation, land owners, state and federal agencies, and non-profit partners to conserve land, water, and traditional foods.
