The richest and most diverse of the woodlands and forests in the Davis Mountains are the mesic forests found from 1,770 to 2,330 m (5,810 to 7,640 ft). These forests are found in stream valleys and other well-watered areas. Indicator species are ponderosa pine and southwestern white pine, plus two small groves of quaking aspen at elevations of 2,300 m (7,500 ft) at the base of the cliffs surrounding the summit of Mount Livermore.
