Invasive Species

    An invasive species is one that has moved into an area that it previously did not inhabit, usually as a result of man's intervention. Often the consequences are negative; valuable food reserves and sources of cover for native species are reduced. The invasive species can negatively affect human needs such as water supply, transportation, recreation, and resource utilization. A host of environmentally sound, physical, chemical and biological control strategies are available to deal with non-native plants and animals.
