As a native of Santa Rosa and avid outdoorsman, Ryan has spent much of his free time on the rivers, the wetlands, farmlands and coastal mountain ranges of the Bay Area and greater California. After high school, Ryan attended the University of California – Davis where he earned both his undergraduate degree and a Masters of Science in Soils and Biogeochemistry. His thesis work focused on mapping and modeling regolith thickness for the western slope of the Sierra Nevadas of California, and linking thickness to water storage and its effects on forest susceptibility to drought-induced mortality. As Pepperwood’s Research Technician, Ryan is helping to lay the groundwork for Pepperwood’s rapidly expanding wireless meteorological and soil sensor network, and is in charge of data management and acquisition from these systems.

Annie Madden is a fire practitioner and land steward whose nature story began in a small town right along the Missouri River. In 2012, she moved to Sonoma County where she attended Santa Rosa Junior College to earn Associate Degrees in Forest and Watershed Management, Natural Sciences, and Parks and Recreation Management. Over the past decade she has gained substantial hands-on experience in animal care, ecological restoration using prescribed fire, and recreation management as a kayak guide along the Sonoma Coast. Her motivation is community-based stewardship and education.

When you can’t find Annie at Pepperwood she is most likely hiking with her dog Bailey or hanging out at the Santa Rosa Junior College Shone Farm facility where she helps train and inspire students of the Wildfire Resilience Program. She is also a dedicated volunteer with the local Prescribed Burn Association, the Good Fire Alliance, and a graduated 2022 Fire Forward Fellow. Annie looks forward to continuing her relationship with the earth at Pepperwood.

Devyn Friedfel was born and raised in the Russian River area where he grew up learning to love the beauty and diversity of Sonoma County. While attending the Santa Rosa Junior College (SRJC), Devyn organized volunteer restoration work days at Shone Farm to help control invasive plants and promote native species. Through the SRJC he had an opportunity to visit Pepperwood and dreamt of someday working there. Devyn moved to Santa Cruz County to finish his bachelor’s degree, then worked up and down the central coast with the UC Natural Reserve System, while simultaneously working as a field biologist for two environmental consulting companies. After 5 years of deeply missing Sonoma County he is happy to be back and a member of Pepperwood team. At Pepperwood, Devyn supports Preserve Manager Michael Gillogly in managing natural resources and infrastructure. He also runs our volunteer workdays in the field and assists with research.
