Lower water temperatures within a streamside buffer strip
The removal of streamside vegetation increases the water temperature in mountain streams. Clearcutting and farming have been found to raise temperatures beyond the tolerance level for trout (68° F). Within the sale area of a commercial clearcut in the mountains of North Carolina, a narrow buffer strip of uncut trees and shrubs was left beside a stream. Although water temperatures within the sale area may have exceeded 68° F., the stream immediately below the sale area was never warmer than 62° F.
