The world’s largest Bebb willow community is a focus for this historic preserve.



Surrounded by thousands of acres of cool forest and meadows, the 245-acre preserve is home to uncommon wildflowers, old-growth ponderosa pine, a rare grove of Bebb willows, herds of elk and deer, porcupine, prairie dogs, more than 120 species of birds, and more than 250 plant species.

Hart Prairie Preserve, with its historic lodge and charming guest cabins, was donated to The Nature Conservancy in 1994 by a local family, owners of The Homestead at Hart Prairie, when they discovered that their property held a globally rare community of Bebb willow trees.

Much of the work at the preserve focuses on the Bebb willow community, the largest known in the world. Conservancy staff also works closely with partners at the U.S. Forest Service, U.S. Geological Survey, and various departments at Northern Arizona University on ecological restoration activities in the surrounding National Forest.

Preserve History

Conservancy preserves in Arizona share much of the colorful history of the state itself. Located on the western slope of the sacred San Francisco Peaks near Flagstaff Arizona, Hart Prairie is an oasis of beauty and grandeur distinguished by its history of rigorous land stewardship and restoration ecology.  The property is listed on the National Register of Historic Places, the Nation's official list of cultural resources worthy of preservation. Its recordable history is a fascinating one that began centuries ago. Learn more.
