Caohai Nature Reserve is a critical wetland habitat in southwestern China, renowned for its rich biodiversity and stunning migratory bird populations, offering unique opportunities for wildlife observation and wetland exploration.
Located in the Weining Yi, Hui, and Miao Autonomous County of Guizhou Province, Caohai Nature Reserve is in one of China's most important wetland ecosystems. Established in 1985, the reserve encompasses a large highland lake—Caohai Lake—surrounded by marshes, reed beds, and mountainous terrain, creating a diverse mosaic of habitats. The reserve is especially famous as a wintering ground for migratory birds, notably the endangered black-necked crane, as well as many other waterfowl species. The landscape combines freshwater lake systems with adjacent karst formations typical of Guizhou, offering rich ecological niches for plants and animals. Visitors to Caohai can engage in birdwatching tours, guided nature walks, and photography to capture the abundant and sometimes rare wildlife. The reserve also preserves the cultural heritage of local Yi, Hui, and Miao ethnic communities, whose traditional lifestyles remain closely tied to the land and wetlands. Beyond biodiversity, Caohai is an important site for environmental research and wetland restoration efforts aimed at protecting this fragile ecosystem. Its relative remoteness offers a tranquil retreat for nature lovers seeking authentic wildlife encounters far from urban centers.
