About 120 hectares of wild purple alfalfa are in full bloom in Tashkurghan in Xinjiang Uygur Autonomous Region, contrasting with snowy peaks across the Pamir Plateau. Over 4,000 meters above sea level, this pasture is a key winter fodder reserve. Herders follow a rotational system – a summer ban lets alfalfa flourish, while winter grazing sustains livestock. This approach balances ecology and animal husbandry.
