Habitat point records from 1985 Smith Loch Sween littoral survey

Loch Sween is situated on the east side of the Sound of Jura, in south-west Scotland. It opens to the south-west and its mouth is partially protected by the small MacCormaig Isles. The main body of the loch is relatively straight, with a fringe of rocks or gravel giving way to a sandy or muddy seabed. There are a number of arms to the loch which add considerably to the diversity of habitats present. Linne Mhuirich forms an arm to the west, with a constricted mouth into Loch Sween forming an area of tidal rapids. At the head of the loch, arms include the silled Caol Scotnish. Adjacent to Loch Sween, once connected to it but now separated by causeway, is Loch na Cille. Loch Sween has been proposed as a Marine Nature Reserve by NCC on account of the high scientific interest and conservation importance of the habitats and communities within the loch. Although a site of historical marine biological recording and research, NCC commissioned extensive systematic littoral and sublittoral surveys in 1982. Further information was required on the distribution and types of littoral habitats and communities present to assess the relative importances of individual areas and the integrated importance of the whole loch. The aims of the shore surveys in 1985 were; to investigate the shores around Ceann an t-Sailein; to assess any temporal variation in faunal communities, particularly molluscan, in the Linne Mhuirich area; and to describe the shores of Loch na Cille. Survey work was carried out during spring and autumn visits. Descriptions of all the sites are included in the report, which also contains a detailed species list and tables showing the numbers of Mollusca associated with algae. The discussion is limited to a summary of the more important information found during the spring surveys. The report concludes that Ceann an t-Sailein adds another habitat type (a shallow tidal bay with a clay floor) to those already known in Loch Sween. Several community types were recorded from the sediment shores. Further variability in molluscan populations was noted but showed no clear pattern which could be related to seasonality. Several mollusc species new to Loch Sween were recorded. Records currently considered sensitive have been removed from this dataset.

洛赫斯温位于苏格兰西南部的朱拉海峡东岸，其口部朝西南方开放，并被微小的麦克科马格群岛部分保护。该湖泊的主体相对笔直，岩石或砾石边缘逐渐过渡至沙质或泥质的海底。湖泊中有多个分支，极大地丰富了现有的栖息地多样性。林恩穆里奇向西形成了一个分支，其狭窄的口部汇入洛赫斯温，形成了一个潮汐急流区域。在湖泊的上端，分支包括斯科特尼尔的石拱。洛赫斯温与相邻的洛恩纳基尔湖曾相连，但现已被堤道隔开。洛赫斯温因其内部栖息地和群落的高科学价值和保护重要性，被国家海岸委员会（NCC）提议设立为海洋自然保护区。尽管该地区是历史上海洋生物记录和研究的地方，但NCC于1982年委托进行了广泛的系统性的近岸和海底调查。为了评估各个区域相对重要性以及整个湖泊的综合重要性，需要进一步了解近岸栖息地和群落分布及类型。1985年的海岸调查旨在调查塞恩安特萨莱因附近的岸边；评估林恩穆里奇区域的动物群落，尤其是软体动物群落，随时间的变化；以及描述洛恩纳基尔湖的岸边。调查工作在春季和秋季的访问中进行。所有地点的描述均包含在报告中，报告还包含详细的物种列表和展示与藻类相关的软体动物数量的表格。讨论仅限于春季调查中发现的更重要的信息总结。报告得出结论，塞恩安特萨莱因为洛赫斯温增添了另一种栖息地类型（一个浅潮汐湾，底部为粘土质）；在沉积物岸边记录了多种群落类型。软体动物种群的变化进一步加剧，但并未显示出与季节性相关的明确模式。记录了洛赫斯温新出现的几种软体动物物种。目前被认为是敏感的记录已被从该数据集中移除。
