Bassurelle Sandbank SAC Monitoring Report 2017

Bassurelle Sandbank Special Area of Conservation (SAC) is a Marine Protected Area (MPA) located in the Dover Strait, 30 km south of the Dungeness peninsula within the ‘Eastern English Channel’ Charting Progress 2 (CP2) sea area. The site was designated to protect the Annex I Habitat ‘Sandbanks which are slightly covered by seawater all the time’. This monitoring report is informed by data acquired during the first Sentinel (Type 1) monitoring survey carried out at the Bassurelle Sandbank SAC in 2017 and will form part of the ongoing time series data for this MPA. The report describes the extent and distribution of the topographical sandbank and supporting habitat and determines the structural and functional attributes of this feature. It also compares sediment composition and biological assemblages to observations made during the habitat verification survey in 2013.巴叙雷尔沙洲特别保护区（Special Area of Conservation, SAC）是坐落于多佛尔海峡的海洋保护区（Marine Protected Area, MPA），地处邓杰内斯半岛以南30公里处，归入“东英吉利海峡”制图进展2（Charting Progress 2, CP2）海域范围。该保护区的划定旨在保护附录I生境“长期轻微被海水覆盖的沙洲”。 本监测报告的数据来源于2017年在巴叙雷尔沙洲特别保护区开展的首次哨兵（Type 1）型监测调查，相关成果将纳入该海洋保护区的长期时序数据集。报告阐述了该沙洲地形的分布范围与支撑生境，并明确了该地貌的结构与功能属性；此外，报告还将沉积物组成与生物群落状况，与2013年生境验证调查的观测结果进行了对比。
