There may not be falling leaves, but there’s plenty to see during autumn in the Mojave Desert! Explore the variety and understated beauty of the desert in fall in this all-day field class. You’ll learn the common shrubs, trees, and fall-flowering annual plants of the Joshua tree and pinyon-pine woodlands. The class covers both scientific and common names, plus the guides and botanical keys you can use to identify these plants in the field.

This class is held at Black Rock, with the classroom portion taking place in the Black Rock Nature Center education room.
Anyone may attend! Material is accessible for the plant-curious, amateur botanist, and professionals alike.

Meet your instructor: Melanie Davis lives in Joshua Tree and is a lead field botanist at UC Riverside's Center for Conservation Biology in Palm Desert. She has been working in the California deserts since 2017. Her field research takes her to remote corners of the Colorado, Mojave, and Sonoran deserts to study the effects of climate change and human disturbance on desert ecosystems, as well as the distribution of rare native plants. She is also an artist and has published illustrated field guides to several groups of native desert plants. Melanie holds a bachelor’s degree from The Evergreen State College and is certified as both a Desert Ecologist and Naturalist through College of the Desert. She is also a retired park ranger, an amateur herpetologist, and a graduate of the UCR Palm Desert Master Naturalist and Master Climate Steward programs.
