The process of identifying potentially valuable ecological functions of NI plants could start with a checklist of relevant managementoriented, system-based questions such as: 1. Does the existence of the species enhance management goals of the system? Is the species noninvasive or a threat to resources of concern, particularly in adjacent systems? 2. Is the species ecologically similar to an extirpated IN species? Could it serve a similar ecological role in the system?
They reduce the value of these systems" (Bazzaz 1986). For many speakers of English the term weed brings to mind images of rapidly growing pests choking out valuable species in agricultural lands, gardens, or lawns. Because management of these areas usually involves regular disturbance of the vegetation cover and soil, most unwanted species on them are characterized by their ability to colonize disturbed areas and to reproduce quickly. Plants of this type often build up large populations that disperse propagules far and wide, increasing chances that some will drop in a freshly disturbed area before the population itself is overtaken by late-successional species (Frenkel 1970; Harper 1977).
