Habitat 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.

本报告详述了斯克默岛及其相邻的马尔洛斯半岛的主要沿岸生境以及选定特殊地点及其周边群落。信息以适宜纳入拟设法定海洋自然保护区的管理计划之格式提供。所选地点旨在代表尽可能广泛的各种生境，包括不同朝向的基岩和巨石海岸、潮汐涌动区域以及洞穴。共调查了22个地点。本报告对这些地点及其相关群落的描述和总结进行了详细阐述与讨论。野外数据呈现于附录一，标注物种名录提供于附录二。同时，该报告还将地点和群落的摄影记录提交至国家海岸委员会（NCC）。附录三提供了照片目录。本研究成果在参考先前研究的基础上进行讨论。调查区域内若干物种在或接近其地理分布的北部极限处出现，增添了该区域的科学价值。鉴于此次调查，建议未来工作应致力于对特殊生境的详细调查以及全面物种名录的编制。对斯克默海洋保护区沿岸带作为保护区的价值进行了评估。
