Utah Master Naturalist is an award-winning Utah State University Extension program that promotes stewardship of Utah's natural world through place-based, experiential field courses across the state. Although successful in eliciting positive short- and long-term impacts, Utah Master Naturalist's traditional five-day field courses were inaccessible to many students and instructors due to constraints on time and location. This case study examines Utah Master Naturalist's first hybrid course, Desert Explorations, and describes the positive results from the pilot study, how a hybrid course solves accessibility issues, and how field-based learning theories can be adapted to online education through careful design.
