The Forage Resource Study Group (FRSG) began in 1990 to track participation and the utilization of priority forage species. This long standing multiparty monitoring group involves the ranches, AZ State Land Department, AZ Game & Fish, and the US Forest Service, as well as other partners, and goes out into the field two times a year, come rain, dust storms or snow, to survey the land and ensure all parties involved are working towards the ecological stability of the landscape.

Monitoring plots built by the USFS in the 1940s have been systematically revisited during the past five years. Instrumentation includes rain gauges, utilization cages and mapping, photo plots, condition and trend transects, and a wildlife census. Diablo Trust has also supported and encouraged more focused research projects, particularly when they augment knowledge about resource condition and offer new insights for management.
