Title: Boundary Monument 75E, Southeastern Arizona - 1994
During the past century, the grassland has continued to become more shrubby with increases in such plants as broom snakeweed and velvet mesquite. The mesquite, occurring here near the upper limits of its range, has remained short, probably as the result of catastrophic freezes that have visited the area. Bush muhly is found beneath some of the mesquites. (Raymond M Turner).
