Findings are presented on the growing danger to national forests, recreational, and agricultural lands from noxious weed infestations. These infestations are causing costly and irreparable damage to wetlands, wildlife habitat, wildlands, rangelands, and aquatic and riparian areas on public and private lands all across the United States, especially in popular western recreation states. The release of the paper was scheduled to coincide with National Invasive Weed Awareness Week, February 28 through March 3, 2000. Chair: Barbra H. Mullin, Montana Department of Agriculture, Helena.
