Managing dominance of invasive plants in wildlands.

摘要

Invasive exotic plants threaten nature reserves and wildlands, where eradication may be neither a cost-effective nor an obtainable objective for controlling widespread weeds. In such cases, long-term management objectives should address the maintenance of desirable community and ecosystem processes through reduction in invasive plant abundance and distribution to acceptable levels. Strategic approaches to invasive plant control should include restoration of critical functional groups, mitigation of environmental stressors and reduction in exotic sources of disturbance to improve biotic resistance of the native community and reduction in invasive plant dominance. Monitoring to assess progress toward management goals is essential to identify needed changes in protocol as more is learned about drivers of community processes.
