Who We Are

Prosser and Metzger families

Diablo Trust Ranches in Coconino County, Arizona

As neighbors, our families have shared resources and ideas for managing our respective ranches since the 1950s. Urban influences, public recreation pressures, anti-grazing activists and pressure from developers threatened both our ranches in the early 1990s. We came together to form the Diablo Trust in 1993 Effectively combining Bar T Bar Ranch and Flying M Ranch.

We began our relationship by sharing equipment and gradually developed into sharing knowledge, experiences and other valuable resources. Our conservation accomplishments are something we’re very proud of.

We’ve worked with the U.S. Department of Agriculture’s Natural Resources Conservation Service, Arizona Game and Fish and the Arizona Antelope Foundation to restore 24,000 acres of grassland for antelope. Three years of surveying have shown that antelope reproduction rates have almost tripled. Additional monitoring and radio collars, read by satellite, show antelope moving into newly created openings within weeks of treatment.

The Prosser and Metzger families were recognized in conjunction with the Environmental Stewardship Award Program (ESAP) in 2006.

The Environmental Stewardship Award Program (ESAP), sponsored by the National Cattlemen’s Beef Association (NCBA), Dow AgroSciences and Natural Resources Conservation Service (NRCS), annually recognizes the outstanding stewardship practices and conservation achievements of U.S. cattle producers across the nation. The families selected as regional ESAP winners have successfully conducted stewardship practices that can serve as exemplary models for all cattle producers. They are actively working to protect and improve the environment and have proven that environmental stewardship and good business can go hand-in-hand.
