Final Vegetation Treatments Using Herbicides Programmatic Environmental Impact Statement

Document Type


Publication Date



This Final Programmatic Environmental Impact Statement (PEIS) analyzes the potential direct, indirect, and cumulative impacts associated with the Bureau of Land Management’s use of herbicides on the human and natural environment. An accompanying Final Programmatic Environmental Report (PER) discloses the potential impacts to vegetation and the environment from utilization of non-herbicide treatment techniques, including, but not limited to, fire, mechanical, manual, and biological control methods. Together, herbicide and non-herbicide treatments make up the integrated pest management program that the BLM would apply to approximately 6 million acres annually of public lands in 17 western U.S. states, including Alaska. Alternatives analyzed in the PEIS include the No Action Alternative, or continuation of present management, as outlined in four previous EISs dating from 1986 to 1992. In addition, four action alternatives were evaluated: 1) the Preferred Alternative, which includes herbicide treatments on about 932,000 acres annually and adoption of four new herbicides for use on public lands; 2) a no herbicide use alternative; 3) a no aerial spraying alternative; and 4) an alternative that would limit herbicide use to non-acetolactate synthase-inhibiting active ingredients.
