NAU Arboretum Tree Walks
“The mission of the NAU Arboretum is to preserve historic and interesting plants on campus, maintain and enhance the beauty of the campus, and to educate the University and greater Flagstaff communities about these plants.”
The NAU Arboretum consists of three tree walks located on north campus.
The Wommack Tree Walk Accordion Closed
Dr. Donald Wommack was a Forestry professor at NAU from 1968 to 1999. He first started the NAU Arboretum near the San Francisco Peaks and collected plants from around the world. Many of the original plants were moved to the NAU campus and are featured on this walk.
The Littleman Tree Walk Accordion Closed
Mr. Lemuel Littleman was a long-time groundskeeper at NAU from 1947 to 1983. He planted many of the plants on this walk.
The Grimm Tree Walk Accordion Closed
The Grim arboretum was originally planted in the late 1970s by Professor J. Norm Grim, a biologist at NAU. This arboretum reflects the study of altitudinal vegetation zones, a concept pioneered in Northern Arizona in 1889 by C. Hart Merriam, who observed “Life Zones” from the lower elevations of the Grand Canyon to the top of the San Francisco Peaks. Here you can observe plants from the desert all the way to the subalpine zone.
