Species point records from 1982 OPRU Skomer littoral survey

This report describes the major littoral habitats and selected special sites together with their communities around Skomer Island and the adjacent Marloes peninsula. The information is provided in a format suitable for inclusion in a management plan for a proposed statutory marine nature reserve. Sites were selected as being representative of as wide a range of habitats as possible and include bedrock and boulder shores of various aspects and water surge areas and caves. A total of 22 sites were surveyed. Descriptions of these sites together with summaries of their associated communities are given and discussed in this report. Field data is presented in Appendix 1 and annotated species lists are provided in Appendix 2. A photographic record of the sites and communities was also submitted to the NCC. A catalogue of photographs is given in Appendix 3. The findings of this report are discussed in the light of those of previous studies. The chief features of the survey area are: a) the presence of classic examples of shores extremely exposed to wave action; b) shores which provide an exceptionally wide variety of other habitats and communities, and; c) a number of unusual microhabitats, all within a relatively small geographic area. The occurance of several species in the survey area at or near the northern limits of their geographic range contributes to the scientific interest of the area. In the light of this survey, it is recommended that detailed surveys of special habitats and the production of comprehensive species lists should be the aim of any future work. The littoral zone of Skomer Marine Reserve is assessed for its value as a conservation area.

本报告详细阐述了斯莫尔岛及其相邻的马尔罗斯半岛的主要沿海栖息地与选定特殊区域的群落。所提供信息之格式，旨在适用于纳入提议的法定海洋自然保护区管理计划之中。所选取的地点旨在代表尽可能广泛的栖息地类型，包括不同朝向的基岩和巨石海滩、潮涌区域以及洞穴。总计调查了22个地点。本报告对所调查地点及其相关群落的描述进行了概述并展开讨论。实地数据详见附录一，标注物种列表详见附录二。同时，对地点和群落的照片记录也已提交至国家海岸委员会（NCC），照片目录详见附录三。本报告的研究成果在借鉴先前研究成果的基础上进行了探讨。调查区域内若干物种的分布达到或接近其地理分布的北部极限，这增加了该区域的科学价值。鉴于本次调查，建议未来工作的目标应为对特殊栖息地进行详细调查，并编制全面的物种名录。对斯莫尔海洋保护区沿岸地带的价值作为保护区进行了评估。
