The paper is well researched and well written, but in a country such as China, where nearly all natural vegetation has been removed or highly modified, especially in the eastern half of the country, invasive plants are really not the problem. The problem is that China is so highly disturbed and the natural environment so thoroughly destroyed, or even totally removed in some places, that almost any plants that cover up the bare soil, regardless of their origin, serve a useful purpose. If the natural environments could be restored, it is likely that introduced plants would disappear. Such an experiment was carried out at the Kochi Makino Botanical Garden in Kochi, Shikoku, Japan, where a bare piece of land was restored to what the forest was originally. For the first five or six years the staff made an effort to remove all non native plants, but after the vegetation had developed sufficiently the non native plants essentially disappeared on their own - they were unable to survive in a natural environment. In intact natural forests the introduced plants are rare, but where the land has been stripped of its natural vegetation and where the soil has been badly disturbed, then there are introduced plants, and also native invasive plants. The best way to combat introduced plants is to restore the natural environment. Perhaps the authors should address the loss of China's natural vegetation in relation
