Along with climate and topography, geology and soils may be considered the dominant factors that shape the potential vegetation of any region. A significant part of the influence of geology on forest vegetation is mediated through its effects on soil development.
Soils are a complex, natural mantle covering the surface of the earth.
Many factors interact in the development of any soil. The purpose of this exercise is to determine the influence of geology and soils on the composition and productivity of forests in the Ridge and Valley Physiographic Province. This lab exercise will consist of a number of stops where the various geologic and soil factors influencing forest development in the Ridge and Valley can be observed. Introduction to the geology of the Valley and Ridge. Discussion of factors influencing productivity.
