Our vibrant community of Pepperwood volunteers support our mission and make Pepperwood thrive. Volunteers enjoy access to the preserve and its natural resources. Opportunities to get involved include digging in at our monthly Volunteer Workdays, conducting field research and contributing data to our Community Science projects, helping out with our community events, and supporting our ongoing education and conservation efforts as a dedicated and trained California Naturalist and Pepperwood Steward.

If you have a passion for land management, fundraising, science or sharing our knowledge of the natural world with the public, there is a place for you.

Community Volunteer Workdays

Hardy volunteers are needed to assist with various outdoor projects related to the ecological restoration and management of the preserve. Projects may include invasive species removal, native seed collection, plant propagation, trail maintenance, building infrastructure and habitat restoration.

Native Plant Garden Volunteer Workday (Seasonal)

Science tells us that exposure to microbes in soil makes you happier!  Come out for a morning of sunshine and bird songs while learning about native plants by joining our Native Plant Garden Volunteer Workday, also known as “Garden Club.”  Meeting on every other Friday morning through the season, our native plant garden receives loving attention in order to continue to bloom and beautify throughout the season.

Volunteers play a major role in growing Pepperwood’s Stephen J. Barnhart Herbarium, which provides documentation of the vascular plants found across the preserve and contributing to community science.

Community Science

Volunteers contribute to many research projects under the umbrella of our Sentinel Site, which serves as a cohesive conservation model integrating climatic, abiotic, and biological monitoring projects that directly inform our land management practices and objectives. Nearly all of our projects involve community scientist support – including our grassland monitoring, phenology studies, breeding bird survey, and herbarium collection.

Steward Program

Pepperwood Stewards are highly-trained volunteers who make a minimum two-year commitment of service at Pepperwood. Stewards have the opportunity to contribute to our education, research and restoration projects, and partner with Pepperwood’s network of scientists and conservation planners.

The first step to becoming a Steward is to enroll in either the California Naturalist Program or the Climate Stewards program offered through Pepperwood. Completion of this course enables certification through UCCE. If you share our passion for the environment and are willing to make a long-term commitment to supporting our research and education programs, consider becoming a Pepperwood Steward!
