Unformatted text preview: Removal of Invasive Plant Species Plant With W.R.V. April 1, 2007 Environmental Conservation, M. Stephens By, Karen Gale It takes one person at a time to make a difference. difference. Non-native invasive (NNI) plants are exotic species Non-native that are also ecological pioneers and colonizers. They are plants that, once introduced, can quickly establish themselves in ecologically disturbed communities. Non-native invasive species typically displace native flora because they have faster growth rates, efficient dispersal mechanisms, and tolerance of a wider range of conditions. Because they are not normally found in the region where they have been introduced, nonin native invasive plants often lack natural predators and native diseases that control their populations in their native environments. Ron shows us the degradation of the under-story by humans. under-story Why Remove Exotic Invasive Species? Species? To preserve wildlife habitat. Invasive plants have become recognized in recent Invasive years as a major threat to the integrity of natural areas. Invasive species can alter natural ecological processes Invasive by reducing the interactions of many species to the interactions of only a few species. According to a 1996 report by the Nature According Conservancy, invasive species have contributed to the 42 percent population decline of threatened and endangered species in the U.S. Conserve our Planet Conserve Non-native species threaten two-thirds of Non-native endangered species world wide, and are considered by some to be second most important threat to biodiversity after habitat destruction.

Pull seedlings and small or shallow-rooted plants Pull when soil is moist. Dig out larger plants, including the root systems. Dig Use a spading fork or weed wrench for trees or Use shrubs. Herbicides: We do not recommend this method Herbicides: with volunteers. Herbicides should be used only as a last resort – in cases where the infestation cannot be controlled through other means.
