Invasive Species
Background from Wikipedia Lantana Invasion of abandoned citrus plantation; Moshav Sdey Hemed, Israel; May 2, 2006 The term invasive species refers to a subset of those species defined as introduced species or non-indigenous species. Keystone species can alter ecological relationships among native species and can affect ecosystem function, economic value of ecosystems, and human health. A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not native), becomes capable of establishing a breeding population in the new location without further intervention by humans, and spreads widely throughout the new location. Natural range extensions are common in many species, but the rate and magnitude of human-mediated extensions in these species tend to be much larger than natural extensions, and the distances that species can travel to colonize are also often much greater with human agency (Cassey et al. 2005). The majority of introduced species do not cause significant ecological change or environmental harm because they exist primarily in habitats already subjected to intensive human alteration; such species may not be considered 'invasive'.
