Tásmam Koyóm is the Maidu name for “Humbug Valley,” a diverse 2,325-acre meadow and forest ecosystem located in the Upper Feather River watershed of Plumas County that was appropriated by Euroamerican settlers during the California Gold Rush. On September 18, 2019, Tásmam Koyóm, was returned to the Maidu Summit Consortium (MSC), the non-profit vehicle of the Maidu people. The Sierra Fund is partnering with MSC to provide technical and administrative support to the vision of long-term Maidu landscape management.
Tásmam Koyóm is part of the ancestral lands of the Mountain Maidu people, where they lived for thousands of years. The Sierra Fund is supporting the First Nation of Plumas County in planning for, executing, and adaptively managing a phased program of restoration on Maidu land that bridges the gap between traditional ecological knowledge (TEK) and Western scientific approaches. This effort is predicated on using Maidu TEK as a starting place to facilitate the engagement of technical experts.
