SBTS Collecting All Trail User Input for Lost Sierra Trails

The Sierra Buttes Trail Stewardship (SBTS) is collecting public input and is applying for California State Proposition 68 “Statewide Park Development and Community Revitalization Program” to prioritize future projects and predict the economic impact of trails in the Lost Sierra region. SBTS and California State University – Chico have built a trail survey to collect economic and demographic information on all trail system users in the Lost Sierra.

Add your input to the survey.
