Abstract: Exotic species in non-native lands pose a serious threat to biodiversity, and over time can lead to extinction of native species.  Understanding the characteristics of invaded sites could help to stem the current massive loss of biodiversity.  It is generally recognized that disturbance plays a significant role in the rate of invasibility of land (Fox and Fox 1986, Elton 1958).  However, communities are known to vary in their susceptibility to invasion (Fox and Fox 1986, McIntyre 1988).  I examined two disturbances with different origins to see if I would detect a facilitative effect by either or both.  I examined both anthropogenic disturbance and natural flooding disturbance at sites along Big Stony Creek in Giles County, Virginia.  The trends discovered in this examination show that disturbances of both types exhibit higher overall plant densities and diversities.  However, exotics on their own did not exhibit strong trends, which could be ameliorated with a change in study design, or perhaps, could be attributable to a yet unknown mechanism by which exotics flourish.
