What impact might these changes have on the rate at which plant invaders arrive in our natural communities and on the effects they have there? One can certainly list some major changes underway in the environment and review the ways in which th

Unlike weed control in agricultural situations where the objective is to control all species except the crop, resource managers often want to control one or several undesirable species while causing little or no impact to components of the native community or to natural ecological processes.

Defining Indigenous Species: An Introduction in making a decision to manage a potentially problematic species invasion is to first determine whether a species is a natural component of, or is indigenous to, the community in question.

Where there is a clear, agreed-upon vision of which species are wanted and, better yet, the level of productivity desired—as in a corn field—much of this subjectivity disappears. Here, a
