LHASA - Scientists have found over 150 unsafe invasive species in Tibet autonomous region after two years of research.
Led by Tibet's regional institute of plateau biology, the research team found over 130 invasive plants including crofton weed, and more than 20 invasive animals in the region, like bull frogs and the red-eared slider (a type of turtle), both on the list of the world's 100 most invasive species. They are also found in other parts of China.
Tu Yanli, associate researcher with the institute, said the drastic increase of these species in the area is due to the rapidly growing economy and the more convenient transportation.
The Qinghai-Tibet Plateau, where Tibet is located, has long been recognized as a natural biological shield.
To prevent the invasive species from damaging the local environment, the regional government has taken various measures such as strengthening border inspection and establishing quarantine zones.
