Sara Tashker
Sara is a certified organic farmer and Zen Buddhist priest in the lineage of Shunryu Suzuki Roshi.

Gifford Hartman
Gifford is a writer, activist, and educator who focuses on the intersection of labor and ecology. He is a trainer-of-trainers for Global Labour University (GLU), guiding activists from around the world through GLU’s “Just & Green: Labour’s Ecological Question” course, which trains them to help their communities become more ecologically sustainable. Gifford also guides the ritual circumambulation of Mount Tamalpais every solstice and equinox, a tradition begun by poets Allen Ginsberg, Gary Snyder and Philip Whalen in 1965. This circular walk up and around Mount Tam draws on an Asian spiritual tradition of experiencing landscapes as sacred, and is based on a fusion of Zen Buddhism and ecological consciousness. Gifford met Bruce Byers during one of these ritual hikes.

Robin L. Chandler
Robin is an artist, archivist, and historian living in Oakland, California. As an artist, Robin asks “What can art possibly do to help save the planet, at a time when humankind’s disregard for nature places our future in jeopardy?” She uses oil paints, watercolors, or pastels on a range of surfaces including canvas, board, and paper. In the language of color, light, hue, shape, and texture, she captures glimpses of the world’s beauty that foster a sense of kinship with the earth, and leads viewers into landscapes of interconnectedness with nature. Robin’s work has been exhibited most recently in Passion for Landscape by the Mono Lake Committee and is featured in her 2024 book, Awakened in the Range of Light: Art, Pilgrimage, and Friendship in the Sierra Nevada. She created the frontispiece illustration for Bruce Byers’s book Nature on the Edge.
