dc.descriptionThe Davis Mountains are a lava canyon region resulting from deformational movements of late Cretaceous time, later lava flows, and consequent severe erosion. Mt. Livermore, the highest point in the group, probably marks the line of a fissure eruption. Early investigators of the area were collectors, but not always botanists; many of the later visitors to the region made collections, and a few published various studies of the vegetation. Comparison of the records of Ft. Davis and MacDonald Observatory indicate an average annual precipitation of about twenty-three inches on Mt. Livermore. Since about one-half of this falls during the three summer months, the growing season is limited and xerophytic conditions ordinarily prevail for most of the year. Likewise the temperature records and the frost data show a limited growing season. The vegetation of the north face of the upper slope of Mt. Livermore is definitely a part of the Petran montane forest. Most of the area belongs to the woodland climax, its structure consisting of various combinations of the Pinus-Juniperus-Quercus association. Some of the canyons have their own characteristic vegetation. The outlying foothills and nearby plains are characterized mostly by desert scrub
