Dict. of natural resource management, c1996 (noxious plant: A plant that may or may not be specified by law as being undesirable, troublesome, and difficult to control or eradicate. Typically, noxious plants are shrubs and perennial or annual plants rather than tree species, and have the capacity to readily colonize areas such that they can completely stifle the growth of other plants.) The dict. of forestry, c1998 (noxious plant (weed): a plant specified by law as being especially undesirable, troublesome, and difficult to control) Bureau of Land Management’s weeds website, viewed Dec. 29, 2003 (What is a noxious weed?: The term "weed" means different things to different people. In the broadest sense, it is any plant growing where it is not wanted. Weeds can be native or non-native, invasive or non invasive, and noxious or not noxious. Legally, a noxious weed is any plant designated by a Federal, State or county government as injurious to public health, agriculture, recreation, wildlife or property. A noxious weed is also commonly defined as a plant that grows of place (i.e. a rose can be a weed in a wheat field) and is "competitive, persistent, and pernicious." Are invasive plants the same as noxious weeds?: No. Invasive plants include not only noxious weeds, but also other plants that are not native to this country. The BLM considers plants invasive if they have been introduced into an environment where they did not evolve.) Callihan, R.H. Idaho’s noxious weeds, 1999, via WWW, Dec. 29, 2003: introd. (What is a noxious weed? Noxious weeds are plant species that have been designated "noxious" by law. The word "noxious" simply means deleterious, and all listed weeds are deleterious by definition. There are hundreds of weed species in Idaho; however, only 35 are designated noxious by Idaho law as of 1977. Currently, the Idaho Department of Agriculture uses the following criteria for designation of a noxious weed: 1) It must be present in but not native to Idaho. 2) It must be potentially more harmful than beneficial to Idaho. 3) Eradication must be economically physically feasible. 4) The potential adverse impact of the weed must exceed the cost of control) Froude, V.
