| Zusammenfassung: | The Davis Mountains are a lava region resulting from deformational movements of late Cretaceous time, later lava flows, and consequent severe erosion. Mount Livermore, the highest point in the group, probably marks the line of a fissure eruption. Early botanical work on the area was done by collectors and descriptive writers; investigations since 1900 have dealt mostly with the ecological phases of botany. Comparison of the records of Fort Davis and McDonald Observatory on Mount Locke indicates an average annual precipitation of at least twenty-five inches on Mount Livermore. The vegetation of the north slope of Mount Livermore is a part of the Petran montane forest. Most of the area belongs to the oak woodland or to various combinations of Pinus-Juniperus-Quercus groupings. Some of the canyons have their own characteristic vegetation. |
