Green Thumbs - Forest Restoration Volunteers

Pre-registration is required so we can safely plan for enough staff and tools.

The 2026 Green Thumbs Restoration Volunteer Season is here, and we’re inviting you to help care for your public lands in the San Bernardino National Forest.

Join us on select Saturdays from 9AM–3PM to make a direct impact through hands-on conservation work. Volunteers will collect native seed, plant native trees and plants, support our Forest Service nurseries, weed and water restoration sites, and help clean up trash and graffiti. Every project plays a role in restoring habitat, strengthening forest resilience, and protecting the landscapes we all love.

2026 Volunteer Dates:
April 25 (Earth Day)
May 2
May 16
June 3–5 (National Forest Week)
July 11
August 1
September 26 (National Public Lands Day)

Whether you’re new to volunteering or a returning steward, this is your opportunity to give back, get your hands in the soil, and be part of a community committed to conservation.
