Supporting Mountain Communities Through Recreation

The Sierra Buttes Trail Stewardship (SBTS) was born from ordinary people responding to the crisis of federal trail closures in the Downieville area forests.

We wanted to preserve access to these amazing public lands. Offering volunteer labor to the government was the solution, and it needed a big community effort.

Today, SBTS connects government agencies, outdoor enthusiasts, thousands of volunteers, local businesses, industry sponsors, and private organizations on trail building and trail maintenance projects throughout the Lost Sierra region. And in partnership with the Tahoe and Plumas National Forests, SBTS also produces world-class festival events that showcase the mountain communities they take place in, as well as introducing visitors to recreational opportunities on our surrounding public lands.

Our Community Needs Your Help

We think of SBTS as a community development organization.

Over 70% of the land in Plumas and Sierra Counties is federally managed public property. Economically, that’s an extreme burden on the small property tax bases of the local communities. The region flourished in the gold mining and heavy timber era. In those days the public lands provided the jobs and created the individual wealth as an extraction economy. Families could make a good living and public services were plentiful. But as extraction dried up by the early 2000s, Plumas and Sierra had slipped to 2 of California’s 3 most economically and public-service depressed counties. We believe the solution lies in forests. By creating a sustainable recreation economy through singletrack trails, we are helping to bring public lands back in balance to directly support our citizens. We are revitalizing our working landscape – bringing new jobs in the forest and pride to our community, while attracting people here to visit and work. We are restoring economic viability in two of the poorest counties in the state – Sierra and Plumas Counties – through our work.

Building quality singletrack is a complicated endeavor.

SBTS employs 100% local professional staffing both on the trail and in meeting rooms with federal government, state and county officials. Our payroll dollars are re-spent in the community, and our projects create additional revenues for regional experts such as geologists, wildlife managers and soils engineers. Through our partnership with the US Forest Service, we are creating community benefit projects using trails as a tool – transforming historic paths and digging new routes in order to create a system of world-class trails on forest service and privately held lands. With more trails in the area, we are specifically targeting extended visitor stays – more days spent on the trails means more customers in town for the local businesses and more tax revenue for City and County coffers.

The Lost Sierra Master Trails Plan is SBTS’s long-range effort to link the regional communities together with a trails network that makes extended touring and grand outdoor adventures possible.

Executing the plan takes buy-in from local leadership and the collaborative work of seeking citizen input throughout the planning process. The concept will provide public access to trails right from town for all ages and abilities. We provide presentations to local federal, city and county stakeholders and citizens to get them engaged in project planning, implementation and the ongoing maintenance and stewardship.

Our Active Projects

Our Active Projexts

We focus on five things with our projects:

  • Multiple-use trails: hiking, mountain biking, e-biking, equestrian and off highway vehicle
  • Working partnerships with land agencies and local officials
  • Fundraising abilities and financial stability
  • Public engagement and youth involvement directly on the trail
  • Long term collaborative vision with our community

These are our active projects we have either in planning or where we are moving dirt with our professional trail crew and the hundreds of volunteers who help us create Dirt Magic.

The Beckwourth Peak Recreation Project area includes the construction of a new 19.79 mile long trail.

The Beckwourth Peak Recreation Project includes the NEPA/CEQA (environmental documentation and surveys) and the construction of a new 19.79 mile long mutli-use trail, connecting the City of Portola with the recreation community of Gold Mountain.

The project area ranges from approximately 5,000 feet to the slopes of Beckwourth Peak at approximately 6,000 feet above sea level. The habitat is mixed conifer, areas of meadows, open rocky areas, rock outcrops, and mountain tops.
