The Vetiver Grass Technique (VGT) was introduced into China in 1988 via Mr. Richard Grimshaw, the Chairman of International Vetiver Network. It is an excellent ecoengineering and phytoremediation technology that has been used for the purposes of soil and water conservation, environmental protection, habitat restoration, disaster and pollution control and so on. In the last two decades, VGT has been applied to over a dozen of provinces in southern China, and has made significant ecological and social benefits. As a matter of fact, before it was introduced into China, “wild” vetiver had already existed in Hainan, Guangdong, Fujian for long time, which can be traced back to 1936. However, there has not been conclusive evidence or information so far whether the vetiver is native to China or imported from abroad. At present, the only reproduction method of the cultivated vetiver around the globe is through asexual means (e.g., tillering), and vetiver sprawl and “repellent” phenomena haven’t been found in China. In contrast, vetiver can improve harsh habitat conditions and therefore benefits the growth of other native species, which subsequently leads to the shrinking or even disappearance of vetiver due to its poor tolerance to shade. In addition, vetiver is particularly sensitive to herbicides, and therefore, often can be completely annihilated by the spraying of herbicides. In conclusion, there is no scientific basis to conclude that vetiver is an alien invasive species and has potential to become a weed.
