Report: Macrozoobenthos: Lütetsburger Plate – TMAP-Monitoring (1999)»

The “Trilateral Monitoring and Assessment Program (TMAP)” introduced an integrated and methodologically uniform monitoring of the Wadden Sea ecosystem by the three neighbouring countries Netherlands, Germany and Denmark. In the course of the implementation of this programme, the Lower Saxony Wadden Sea National Park Administration commissioned the NLÖ Coast Research Centre in autumn 1998 with the establishment and continuous investigation of 4 monitoring stations for the monitoring of the macrozoobenthos on the Lütetsburger Plate (Steuwer 2000). Together with the long-term stations of the NLÖ Coast Research Centre in Norderney Islandwatt, which already existed since 1976, a continuous eulitoral station profile from the mainland line to the island watt was established. According to the TMAP guidelines, the monitoring stations on the Lütetsburger Plate are examined twice a year in spring and autumn. In the context of the monitoring of the eulitoral mussel deposits on the Lower Saxony coast, the area’s shell banks have been mapped repeatedly in recent years (OBERT & MICHAELIS 1989; Michaelis et al. 1995, ZENS et al. 1997, HERLYN & MILLAT 1997, MILLAT & HERLYN 1999). Since 1994, a permanent station for monitoring the stocking, age distribution and area expansion of mussels has been operated on the plate (MILLAT & HERLYN 1999). The results of the 1999 permanent examinations are summarised in this report.”三边监测与评估计划（Trilateral Monitoring and Assessment Program, TMAP）由荷兰、德国、丹麦三个邻国牵头，对瓦登海生态系统（Wadden Sea ecosystem）开展了一体化且方法统一的监测工作。在该计划的实施过程中，下萨克森州瓦登海国家公园管理局于1998年秋季委托NLÖ海岸研究中心在吕特斯堡滩（Lütetsburger Plate）设立并持续开展4个大型底栖动物（macrozoobenthos）监测站的调查工作（Steuwer 2000）。结合该中心自1976年起便已设立的诺德尼岛滩涂（Norderney Islandwatt）长期监测站，由此构建了从大陆岸线至岛滩的连续潮间带（eulitoral）监测站剖面。根据TMAP的监测规范，吕特斯堡滩上的监测站每年春季与秋季各开展一次监测工作。针对下萨克森州沿岸潮间带贻贝床的监测工作，近年来该区域的贝壳滩已被多次测绘（OBERT 与 MICHAELIS 1989; Michaelis 等 1995, ZENS 等 1997, HERLYN 与 MILLAT 1997, MILLAT 与 HERLYN 1999）。自1994年起，该滩涂便设立了永久性监测站，用于监测贻贝的放养、年龄分布与面积扩张情况（MILLAT 与 HERLYN 1999）。本报告汇总了1999年该永久性监测站的监测结果。
