The Qingtongxia Reservoir Wetland Nature Reserve, spanning an impressive 174.93 square kilometers, stands as the largest Yellow River tidal flat wetland in Ningxia, China. In a significant conservation effort, 35 milu deer were introduced to the reserve in September 2024. This initiative has proven successful, as six milu deer cubs have been born in the reserve to date. The thriving population of these rare deer highlights the effectiveness of the reserve’s ecological management and conservation strategies. A drone photograph captured on November 4, 2025, showcases the milu deer in their natural habitat, underscoring the reserve’s role in preserving biodiversity. The Qingtongxia Reservoir Wetland Nature Reserve continues to be a vital sanctuary for wildlife, contributing to the broader efforts of environmental conservation in the region.
