This article presents the change of habitats for red-crowned crane (Grus japonensis) due to anthropologic activities in Yancheng Coastal Zone Biosphere Reserve, Jiangsu Province, China. As a result of large-scale human exploitation in tidal lands, the habitats of red-crowned crane were significantly influenced and the original wetlands were gradually altered to form artificial wetlands. In the process of rapid economic development in China, an important question that the Reserve and local governments are faced with, is how to lead development activities in a direction that will take into account the contradiction between habitat protection and sustainable economic growth.
