Habitat point records from 1978-79 SWBSS Milford Haven survey

43 sites were surveyed at Milford Haven in 1978 and 1979, but no report was produced. Instead the original raw data sheets and copies of edge-punched cards have been included as a seperate volume of Hiscock, K. (1981) 'SWBSS: Final Report'. Area covered was from St Annes Head and West Angle Bay to the Cleddau Bridge. A wide variety of habitats and communities present including open coast communities of algae and animals on bedrock in the outer Haven and communities on stones, gravel and mud in various locations. An extensive bed of seagrass Zostera marina and a bed of sparse maerl were also present. The presence of jetty piles and other man-made structures enriched the habitats present in the area. The variety of habitats and communities in Milford Haven is so great that no one particular area can be identified here as characteristic, although Watchhouse Point and Dale Point provide good examples of rocky subtidal habitats and communities. N.B. Species have been recorded using the abundance scale as detailed in SWBSS final report. Records currently considered sensitive have been removed from this dataset.1978年与1979年，科研人员对米尔福德港（Milford Haven）的43个调查点位开展了野外调查，但未形成正式研究报告。取而代之的是，原始数据记录表与边缘打孔卡片副本被收录于Hiscock, K.（1981）所著《SWBSS：最终报告》的单独分卷中。本次调查覆盖区域西起圣安妮斯角（St Annes Head）与西角湾（West Angle Bay），东至克莱德奥桥（Cleddau Bridge）。该区域拥有极为丰富的生境类型与生物群落，包括外港基岩上的藻类与动物开放海岸群落，以及分布于不同点位的石块、砾石与泥质生境群落。区域内还分布有大面积的鳗草（Zostera marina）床与稀疏的石藻（maerl）床。码头桩柱及其他人工构筑物的存在，进一步丰富了该区域的生境多样性。米尔福德港的生境与生物群落多样性极高，在此难以界定某一特定区域为典型代表，不过瞭望角（Watchhouse Point）与戴尔角（Dale Point）是岩质潮下带生境与群落的优质范例。备注：物种记录采用了《SWBSS最终报告》中详述的丰度分级标准。当前被认定为敏感的物种记录已从本数据集中移除。
