Invasive Plants
Introduction
The Invasive Plants Toolbox provides resources for managing non-native invasive plants (NNIP) in wilderness areas. It includes relevant laws and agency policies, management guidelines, tools, examples of plans and agreements, and othertools and strategies to help address this growing challenge.
Non-native invasive plants pose a significant threat to the biological diversity and ecological integrity of wilderness areas. They can displace native plants, reduce habitat and forage for wildlife, contribute to the loss of threatened and endangered species, increase soil erosion, degrade water quality, and alter fire intensity and frequency.
Due to their ability to spread rapidly and cross administrative boundaries, the effective management of non-native invasive plants in wilderness requires coordinated efforts among local, state, and federal agencies.

Law and Policy
Section 2 provides a definition of wilderness that directs and guides how wilderness is to be managed to achieve the goals of preserving wilderness as an enduring resource. Several items in the legal definitions found in the Act are applicable to management of non-native invasive plants and should be considered. According to Section 2.(a), wilderness areas are to be managed to protect their natural, unmodified conditions and wilderness character, and leave them unimpaired for future use as wilderness. Section 2.(c) defines wilderness as areas untrammeled by humans, in contrast to areas were human works dominate the land. Further, wilderness retains its primeval character, and is protected and managed to preserve natural conditions, provide outstanding opportunities for solitude, and may contain features of ecological value.
The Wilderness Act in Sections 2 and 4 direct managers to protect and preserve the different qualities of wilderness character. Non-native invasive plants threaten the Untrammeled, Natural, Opportunities for Solitude or Primitive Recreation, and maybe some Unique qualities of wilderness character.
Section 4.(c) of the Wilderness Act may influence the consideration of certain actions taken to manage NNIP. This section lists the generally prohibited uses (allowed only if necessary to meet the minimum requirements for the administration of the area for the purpose of the Act) including no temporary road, no use of motor vehicles, motorized equipment or motorboats, no landing of aircraft, no other form of mechanical transport, and no structure of installation within any such area. For example, use of a motorized sprayer, even one that is battery powered, is prohibited in wilderness unless it is the minimum necessary tool for treatment of NNIP.
Section 4.(d), states that, "In addition, such measures may be taken as may be necessary in the control of fire, insects, and diseases, subject to such conditions as the Secretary deems desirable." Although it does not specify non-native invasive plant species, this section of the Act provides direction applicable to non-native invasive species management activities. It provides the Secretary with the authority to take measures as may be necessary to control insects, and diseases as deemed desirable. Special Provisions MAY be allowed to continue subject to analysis and restrictions. The minimum requirements concept is one screen that is typically applied to projects that are considered under the special provisions section of the Act.
