A herd of wild Asian elephants in southwest China has caught worldwide attention for its long northward journey 500 kilometers away from its traditional home in Xishuangbanna Dai Autonomous Prefecture. The herd left Xishuangbanna National Nature Reserve and started marching northward in mid-March last year, passing through several counties and occasionally wandering into villages and towns. The government of Yunnan Province has been working to address human-elephant conflicts by building barriers, such as fences and ridges.
