As winter deepens in the pine forests of Hulunbuir, north China's Inner Mongolia, temperatures have dropped below -30 degrees Celsius. To protect wildlife such as the lynx and red deer, the reserve is strengthening tech-based conservation. Using monitoring data and drone surveys, the reserve has added six new feeding sites and upgraded 12 others, all equipped with infrared cameras, snow shelters and protective fencing. Daily patrols by rangers, combined with smart technology, are forming a strong protection network to ensure wild animals can safely survive winter.
