Recording of the eider duck population in the Wadden Sea of Lower Saxony in spring 2008. In the Wadden Sea of Lower Saxony, the eider duck population has been recorded twice a year during a tide from the aircraft since 1986. These are the moulting (July/August) and wintering (January/February) stocks. The censuses take place in coordination with Schleswig-Holstein. The data are part of the Trilateral Monitoring and Assessment Program (TMAP). Monitoring of migratory birds (Eiders) in the Wadden Sea of Lower Saxony in spring 2008. The population of migratory birds (Eiders) in Lower Saxony's Wadden Sea is biyearly determined by aerial flight since 1986. Counts are carried out in July/August during the moult and in January/February and are coordinated with Schleswig-Holstein. The data are part of the trilateral monitoring and assessment program (TMAP).本数据集记录了2008年春季下萨克森州（Lower Saxony）瓦登海（Wadden Sea）内的绒鸭（eider duck）种群情况。自1986年起，科研人员便通过航空航拍的方式，每年对该区域的绒鸭种群开展两次普查：分别为换羽期（7月/8月）与越冬期（1月/2月）的种群数量统计。本次普查工作与石勒苏益格-荷尔斯泰因州（Schleswig-Holstein）协同开展，相关数据隶属于三边监测与评估计划（Trilateral Monitoring and Assessment Program，简称TMAP）。
