摘要

Aside from the physical destruction of habitat, invasive exotic plants are the biggest threat to endangered species. When invasive exotic flora invade natural areas the natural biodiversity is often reduced, resulting in the reduction of the invaded ecosystem's ability to support life, including human life. Unfortunately, the ecological devastation resulting from invasive exotic flora is not always obvious to those unfamiliar with the natural world, nor is the direct harm to our quality of lite. No place is safe from invasive exotic flora. 1 hink about the ranger who has the responsibility to protect the natural ecosystems m the Great Smoky Mountains National Park and International Biosphere Reserve. Somehow the invasive species team must try to protect hundreds of square miles from invading exotic flora, a task that has even involved rappelling down cliff faces to destroy invasive exotics threatening the sensitive cliff habitats. Land managers around our country spend billions of dollars each year in the continuing effort to protect natural areas from invasive exotics.
