A resident of Northern Arizona since 1996, Gayle’s interest in native plants was sparked while living and working in the backcountry of Sequoia National Park, CA.

After graduation, she enrolled in the AmeriCorps program and served a one-year term at The Arboretum at Flagstaff. Gayle has worked for the US Forest Service, the National Park Service, Grand Canyon Trust, and as an environmental consultant.

Shannon Benjamin

Volunteer and Tour Coordinator, ext.127

Shannon Benjamin grew up exploring the foothills and sequoia groves of the Sierra Nevada Mountains before moving to the Siskiyou Mountains of Southern Oregon. There she became a devotee of the remote river canyons and peaks boasting rare plants like the carnivorous Cobra Lily. Shannon first moved to Flagstaff in 1998, drawn by the Southwest’s wild places, diverse cultures and Flagstaff’s distinct seasons. Concern about the Colorado Plateau’s fragile landscapes including lack of respect for natural areas and a changing climate necessitated a career change from customer service in the tourism industry to a mission-driven line of work. She volunteered as a Docent for Riordan Mansion State Park, graduated the Flagstaff Leadership Program and was featured in the Daily Sun “Crazy for Corvids” for her popular program celebrating these smart birds. Shannon worked for the Museum of Northern Arizona for eight years in Visitor Services, Education and Volunteer Management before joining the Arboretum at Flagstaff as Volunteer and Tour Coordinator.

Shannon spends her free time reading about the Southwest, hiking and exploring canyons, craters and mountains with her husband and photographing the spectacular Colorado Plateau.
