Restoration Collaboration with Maidu Summit Consortium
2018 to present
OAEC has been working with the Maidu Summit Consortium (MSC) since 2018 in collaboration with other partners to support tribal members in planning for and implementing innovative restoration practices on their ancestral lands at Tásmam Koyóm, including the development of a beaver recruitment strategy.
Tásmam Koyóm is the Maidu name for a valley that is located in northwestern Plumas County, California. This valley was an important Maidu population center within the traditional homeland of the Mountain Maidu for many generations. When Euromerican settlers came to the area, they named it Humbug Valley and established the now abandoned town of Longville. Tásmam Koyóm consists of approximately 2,325 acres, which includes most of the Tásmam Koyóm alpine valley (excluding a private inholding) and certain adjacent hillside forest land. It is contained within four parcels, which are currently used as open space with dispersed recreational activates.
Tásmam Koyóm was returned to Maidu Summit Consortium on September 20, 2019 when Pacific Gas & Electric transferred 2,325 acres of land back to the Mountain Maidu people. This land transfer was a historical moment in MSC and California history. The consortium started in 2003 to advocate for this purpose, and it has been a long struggle to realize the vision that Farrell Cunningham and the MSC board members had “to finally bring our land back home to our people.”
In 2018, the Maidu Summit Consortium (MSC) was awarded a planning grant from the California Department of Fish and Wildlife to:
- Develop restoration strategies for riparian ecosystems at the project site with tribal community support,
- Promote Maidu engagement in applying Traditional Ecological Knowledge (TEK) and technical expertise in restoring tribal ancestral lands,
- Collect data to quantify current conditions in support of restoring ecological conditions on Yellow Creek, support adaptive management and add value to large landscape/ regional conservation efforts and,
- Plan for beaver restoration at Tásmam Koyóm.
As part of this multi-stakeholder planning process, the Occidental Arts & Ecology Center (OAEC) was invited by MSC in 2019 to develop a Beaver Recruitment Strategy. Completed in June of 2020, the goal of this strategy is to identify actions Maidu tribal members and other partners can take to encourage the return of beaver as a vital component in restoring wet meadow and riparian function in the valley. The following highlights key restoration actions OAEC has participated in directly and/or supported indirectly through continued participation in the multi-stakeholder restoration partnership and other MSC capacity building efforts:
In September 2020, restoration partner The Sierra Fund (TSF) co-convened with MSC the second annual Fall Field Camp to bring together project partners to implement TEK-informed monitoring and restoration activities at Tásmam Koyóm. During this three-day convening in the field, MSC members and project partners/supporters worked together to carry out a wide array of monitoring and restoration actions, several of which were recommended in OAEC’s Beaver Recruitment Strategy.
Seeds from culturally significant plants were gathered, processed with some being saved and others planted. Elderberry and oaks were tended and released from conifer encroachment. This conifer removal acted both to reduce fuel loads and provide materials for instream structure building. OAEC gave a presentation and answered questions about recommended steps for beaver restoration in Tásmam Koyóm.
Many of the reaches and sub-tributaries of Yellow Creek have good to excellent conditions to support beaver recolonization and could be further enhanced with the addition of Process-Based Restoration (PBR) instream structures placed in key locations. These structures can help attract beaver to the area because they create the kind of habitat beaver prefer. The structures also help accelerate the pace and scale of restoration and are compatible with the MSC’s desire to use high impact, low disturbance approaches that are in alignment with their TEK values.
With this in mind, the Fall Field Camp concluded with OAEC helping Swift Water Design (SWD) to train MSC members and other project partners how to build various styles of PBR structures including Beaver Dam Analogues (BDAs), Post Assisted Logs Structures (PALS), Brush Mats and other well-proven techniques. This was an empowering moment for the Tribe to learn how easy it is to build these structures and to witness first-hand the immediate benefits of pooled water rehydrating the landscape directly under their feet.
In late October, OAEC joined Swift Water Design to complete Phase 1 of the Process-Based Restoration build. At the completion of that build, 73 structures of varying designs were installed. MSC tribal youth were trained to design and install these structures and several other volunteers from collaborating NGOs participated in the successful build.
In June 2021, 23 more PBR structures were installed by Swift Water Design with the help of OAEC, many volunteers and MSC youth. This brings the current project total to 103 structures built and 3.54 miles of stream channel treated and/or reactivated. This highly successful installation was documented by National Geographic Magazine for an upcoming article on beaver and process-based restoration. Also in June, MSC’s new Executive Director Trina Cunningham, US Fish and Wildlife Service, Swift Water Design, OAEC and other restoration partners co-led a tour for regulators to support improvements in how these innovative projects are permitted. OAEC will continue to take part in this restoration process with more structures being placed in the Fall of 2021 and in 2022.
Since the last installation, the Dixie Fire has burned over Tásmam Koyóm. Once the Dixie Fire has been extinguished, beaver and process-based restoration technical assistance to the MSC will greatly accelerate a swift and low-cost recovery of Tásmam Koyóm. Working with MSC to demonstrate the efficacy of beaver restoration in the context of post-fire recovery will further legitimize and make it more accessible to other tribes and land managers.

Beaver Recruitment Strategy for Tásmam Koyóm
This 53-page report was commissioned by the Maidu Summit Consortium to develop a strategy to recruit beaver to Tásmam Koyóm and the Yellow Creek watershed in Plumas County, California.
