Tracking California and Tribal partners launch project to monitor air quality and strengthen drought resilience in Mendocino, Lake, and Sonoma Counties

There are 26 federally recognized Pomo Tribes and at least 9 other Tribal groups in Sonoma, Lake, and Mendocino counties.The Tribes are concerned about the effects of climate change and the health of communities during rising temperatures, drought, water shortages, and wildfires.


Mendocino, Lake, and Sonoma-Tribal Resilience Initiative on Air Quality & Drought (MLS-TRIAD) is a collaboration between Big Valley Band of Pomo Indians, Middletown Rancheria of Pomo Indians, Sherwood Valley Band of Pomo Indians, and Tracking California, and focuses on improving resilience through air quality monitoring and strengthening existing drought action plans.

Project Activities

Tribes in the region will be offered Purple Air monitors that can be used to measure particulate matter air pollution outdoors or indoors. With better access to real-time air quality information, Tribes will be able to make informed decisions to reduce exposure to air pollution and protect health, such as during periods of wildfire smoke or while monitoring cultural burns.


Project partners will also review existing drought action plans and assess opportunities to make recommendations/improvements to those plans.

Project Funder

MLS-TRIAD is supported by the Regional Resilience Grant Program Implemented by the California Governor's Office of Land Use and Climate Innovation.
