Excerpt from Clearcutting and Burning Slash Alter Quality of Stream Water in Northern Idaho After clearcutting on the Hubbard Brook Experimental Forest (likens and others all trees and woody vegetation felled were left in place. The area was treated with herbicides for three successive summers to insure that major vegetation would not be present. During the first year after treatment, streamflow export of all ions tested, except ammonium, sulfate, and bicarbonate, was from 2 to 53 times greater on the deforested watershed. The large nutrient losses were attributed mainly to alteration of the nitrogen cycle by clearcutting and herbicide application. Two years after herbicide use was stopped, nitrate losses had decreased to the level of several other cutover for est areas nearby. The Hubbard Brook study provides information as to the highest nutri ent losses that might be expected if vegetative regrowth is denied.
