Species 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，尤拉海峡的东岸。其开口朝向西南，口部部分受到小马科马格群岛的保护。湖泊主体相对笔直，岩石或砾石边缘逐渐过渡至沙质或泥质的海底。湖泊中有多条支流，大大丰富了现有的生境多样性。林恩穆里奇向西延伸形成一条支流，其狭窄的口部进入洛赫斯温，形成潮汐急流的区域。在湖泊的上游，支流包括斯科特尼斯的狭口。洛赫斯温与洛恩纳基尔相邻，曾与其相连，现由堤道分隔。洛赫斯温因其内部生境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沿岸和海底调查。为了评估各个区域的相对重要性以及整个湖泊的综合重要性，需要进一步了解沿岸生境和群落的存在分布和类型。1985年沿岸调查的目标是；调查塞恩安特萨利恩沿岸；评估林恩穆里奇区域中动物群落，尤其是软体动物群落，的任何时间变化；以及描述洛恩纳基尔的沿岸地带。调查工作在春季和秋季的访问期间进行。报告中包括了所有地点的描述，还包含详细的物种清单和显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信息的摘要。报告得出结论，塞恩安特萨利恩为洛赫斯温已知生境类型增添了另一种类型（一个浅潮汐湾，底部为粘土质）。
从沉积物沿岸记录了多种群落类型。软体动物种群进一步的变化被注意到，但并未显示出与季节性相关的明显模式。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本数据集中移除。
