Founded in 1993 amid conflict over public lands grazing in northern Arizona, Diablo Trust emerged when two neighboring ranches separated by Diablo Canyon - the Bar T Bar and Flying M - chose collaboration over conflict. By inviting ranchers, agencies, scientists, and communities onto the land, they pioneered a place-based model for collaborative rangeland stewardship rooted in shared learning and trust.

Today, we support ranches, partners, and communities through applied research, community education, and collaborative landscape stewardship. For over 30 years, our work has served as a proven model for sustainable land management across the region and beyond.
