The role of low impact herbicide treatments in ecosystem management
Abstract. Environmentally safe, selective herbicide treatments can be adapted to manage habitats and direct succession toward desired future conditions within the principles of ecosystem 0. Six roles for herbicide treatments in ecosystem management are suggested: create and maintain desired habitats; create mixed and uneven-aged stands; restore damaged landscapes; control exotic, noxious and poisonous plants; maintain recreational areas, trails, and scenic vistas; and manage the rights-of-way for multiple use. Low inpact, selective herbicide treatments include tree injection, cut-stump 6prqys or wipes, basal sprays or wipes, directed sprays, and soil-spot sprays. Selective control can also be achieved using broadcast (aerial and ground) applications of selective herbicides. Currently less than 0.1 percent of national forest lands are treated with chemical herbicides in a typical y-ear. The six roles and treatment methodologies are consistent with the desire of the current administration to decrease pesticide use, to use safer pesticides, and to emphasize integrated pest management programs.
