Longtanhe

Longtanhe is a geographical name referring to several locations in China, most commonly a river and associated protected area in Chongqing Municipality.

Longtanhe River (Chongqing): This is a river located in Yunyang County, Chongqing, known for its scenic beauty and ecological importance. It is a tributary of the Pengxi River, which itself flows into the Yangtze River. The river's watershed encompasses a region characterized by karst topography, contributing to unique geological formations and biodiversity.

Longtanhe National Nature Reserve: Situated within Yunyang County, Chongqing, the Longtanhe National Nature Reserve protects the Longtanhe River and its surrounding area. The reserve's primary focus is the conservation of the region's subtropical evergreen broad-leaved forests and the rare and endangered species that inhabit them, including the Clouded Leopard ( Neofelis nebulosa), various primate species, and diverse flora. The reserve is a critical habitat and a focus for scientific research related to biodiversity conservation in the Three Gorges region. Threats to the reserve include deforestation, poaching, and human encroachment. Conservation efforts are underway to mitigate these threats and maintain the ecological integrity of the area.

Other Potential Locations: It is possible that "Longtanhe" is also used as a place name for smaller villages, settlements, or other local geographical features in other parts of China. Further clarification would be needed to provide specific information about these locations.
