班德湖斑头雁被守护和观望的13年（Wings over Bande Lake: A 13-year Conservation Project for Bar-headed Geese）

Every spring, a group of migratory birds, Anser indicus, arrive at Lake Bande, located at the Source of the Yangtze in Qinghai Province. They are known as the ‘birds that fly the highest in the world’ because they fly over the Himalayas to breed and spend the summer here. This legendary bird mainly lives on the sparsely populated plateau, and its movements are rarely known, which casts a veil of mystery over it. However, since 2012, the environmental protection organisation Green River has protected the Anser indicus at Lake Bande for 13 years. They have observed rare scenes of Anser indicus' life and collaborated with multiple organisations to conduct in-depth research on this bird and related species. In August 2024, I finally got the opportunity to enter Lake Bande as a volunteer systemic designer with a multidisciplinary approach, and try to unravel the mystery of Anser indicus through a brand new complex systems science perspective. I followed National Highway 109 from Mount Kunlun via Kekexili, through Fenghuoshan, to the first town on the Changjiang River at an altitude of 4,539 metres – Tangula Town in Golmud City, Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province. From here, we set off from the Yangtze River Source Water Ecological Conservation Station, following the Ulan Moron, the true source of the Yangtze, through a remote uninhabited area, successfully avoiding the risk of getting stuck in the car, which often occurs, and arrived at Lake Bande – an ideal breeding ground on the Anser indicus migration route.
