Imagine spending your summer in the forests and grasslands of Pepperwood helping scientists better understand our local ecosystem. Picture kneeling in the grass to take a great photo of a sparkling blue beetle.
Every summer this is how TeenNat participants do real on-the-ground science at Pepperwood. Through TeenNat, teenagers find an opportunity to engage with nature and learn from experts about how they can make a difference in the world around them. TeenNat is an award-winning evidence-based program to prepare teens to take their place among those striving to conserve, protect and enhance our natural world. Most importantly, TeenNat participants learn how to apply scientific inquiry and observation of the natural world to their own interests – making science less theoretical and more personal.
Pepperwood’s nationally recognized TeenNat summer program gets teens outdoors and introduces them to the world of conservation science.

TeenNat 2026 Information
This FREE program at Pepperwood is an opportunity for teens to engage in science and art while exploring a 3,200 acre nature reserve. Participants will gain skills in hiking safety, data collection, using field guides to identify plants and animals, and navigating using maps. We will visit unique places across the reserve including ponds, beautiful vistas, oak woodlands, and grasslands. Participants will work with Pepperwood scientists and will meet professionals in STEAM (Science, Technology, Engineering, Art, and Math) careers. At the completion of the program, participants will have created a biodiversity project that may be shared with the Pepperwood community.
We are hosting one 5-week session of TeenNat this summer:
June 23 through July 23, 2026

Inclusion in the Upstream Investment Portfolio
TeenNat was endorsed by Sonoma County's Upstream Investments Portfolio! The Portfolio is a select collection of local, evidence-based programs proven to help eliminate poverty in Sonoma County and ensure equal opportunity for quality education.
Making an Impact with Data that Matters
TeenNat participants gain valuable, real-world experience in conservation science. They are trained to document plant and animal species and their locations via expeditions on the reserve. The teens learn how to manage visual, written, and geographical data as they share, verify, and upload their observations to iNaturalist.org, a worldwide database used by researchers and the scientific community. Each year, TeenNat participants contribute critical data to Pepperwood's science projects.

Upon completion of the summer program, TeenNat Alumni can elect to be part of the TeenNat Leadership program. TeenNat Leaders commit to a greater level of service by continuing to gather biodiversity data, assisting new cohorts of TeenNat, participating in other community science initiatives, serving as volunteers at Pepperwood events, and writing about their experiences. They take part in other Pepperwood events and classes, and special TeenNat alumni events.
