Wilbur-Cruce horses are associated with a family ranch near Arivaca in southern Arizona. The registry initiative's account connects the foundation to horses purchased from the northern Sonora trade and to the region's Spanish mission history. Three generations of the ranch family maintained the population. It attracted conservation attention at the end of the 1980s and beginning of the 1990s.
A 1991 account reproduced by the initiative describes assessment, blood typing and the transfer of horses to conservation breeders as drought and a removal deadline complicated the rescue. These were ranch horses shaped by a particular landscape and management history, rather than simply an interchangeable western mustang group. The rescue aimed to distribute genetic variation among the new breeding groups.
