We work to protect the vital and sacred transboundary rivers that sustain our communities and culture.

Southeast Alaska Indigenous Transboundary Commission (SEITC) is a registered 501c3 nonprofit organization and a consortium of 15 Tlingit, Haida and Tsimshian Sovereign Nations.

SEITC was established in 2014 by resolution to protect the critical transboundary watersheds from rapidly expanding mining development occurring in Canadian headwaters.

SEITC has authority derived from Tribal governments, and each member Tribe has a formally designated representative.

SEITC represents cultural connection to the region. Since time immemorial, the area at the heart of the mining development has been known as the Sacred Headwaters.


SEITC is leading a significant human rights initiative that aims to halt any further harm to the watersheds.

The organization has recently presented a human rights petition to the Inter-American Commission, filing for relief for violations of rights of the member Tribes resulting from hard-rock mining.

SEITC has also filed a petition to the Department of Interior and Commerce alleging violations of the Pelly Amendment to the to the Fishermen's Protective Act of 1967.

In 2019, SEITC was successful in placing the Stikine as one of America's top ten most endangered rivers – a call on the International Joint Commission of the U.S. and Canada to stop mining projects from devastating the river, its salmon, and an entire way of life.
