One of the reasons it is such a threat is because it travels in the air and may fall on areas that did not produce it. The nature of the organisms—the species, functional groups and trophic levels to which they belong—dictates the sorts of actions these individuals are capable of carrying out and the relative efficiency with which they do so.
