OBJECTIVE FORESTRY

Detailed explanation-1: -The most common upland forest trees are aspens, oaks, maples, birches, basswood, pines, spruce, and balsam fir. Because the forest canopy blocks most of the sunlight before it reaches the understory, most understory plants have evolved some degree of shade tolerance.

Detailed explanation-2: -Ozark forests and woodlands include most of southern Missouri. The Ozark highlands are an ancient mountain chain that’s been eroding for a quarter billion years. Limestone, dolomite, and chert are the main rock types, though in some areas igneous rock (such as granite) or sandstone predominate.

Detailed explanation-3: -Upland forests occur where drainage is sufficient so that soils do not become saturated for extended periods of time. Water can either run off or percolate through the soil. The upper canopy is 80% to 100% closed, and sub-canopies of younger trees and shrubs typically exist.
