Management Plan for the 7B Ranch
The 7B Ranch is a 3,073-acre parcel, primarily on the eastern side of the lower San Pedro River, directly east of the town of Mammoth, Arizona (Figures 1, 2). It contains approximately 6.8 miles of the San Pedro River corridor and supports one of the largest, uncut, intact mesquite bosques in the American Southwest. The 7B’s mesquite bosque has been proposed as a state Natural Area and as a National Natural Landmark. Both nominations emphasized the quality and the size of its mesquite bosque, among other worthy conservation characteristics, as the primary consideration for the nominations.
