Prosser and Metzger families

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.
