Mountains to the Sea: The 2025 Southwestern Tribal Summit
Hosted by the Climate Science Alliance and Institute for Tribal Environmental Professionals and in collaboration with Native Coast Action Network, Sacred Places Institute for Indigenous Peoples, Wishtoyo Chumash Foundation, Coastal Band of the Chumash Nation, Great Basin Tribal Alliance, and Indigenous Strategies, the Southwestern Tribal Summit convened for the fourth time with the theme of “Mountains to the Sea” on May 7, 2025 on Chumash lands in Ventura, California.

Participants convened on the coastal plain beneath the southern mountain range to explore meaningful engagement through panel discussions on Respect, Relationships, and Reciprocity, followed by talking circles to inspire connection and collaboration.
The Summit brought together Tribal leaders, environmental professionals, and community members from across the Southwest. The Summit was grounded in engaging discussions and activities centered around the coastal nexus of land and water, and collaborative efforts to advance meaningful Tribal and community-led stewardship and restoration across the region. The Summit provided the opportunity for participants to come together to learn and share in this space between the mountains and the sea.
