Surveys of Harbours, Rias and Estuaries in Southern Britain - Milford Haven and Daugleddau dataset https://portal.medin.org.uk/portal/start.php?tpc=007_NRW_DS111189 The Nature Conservancy Council commissioned the Field Studies Council to undertake studies of the marine inlets of southern Britain, including harbours, rias and estuaries, in order to gain information on the ecosystems present. The study took place between 1985 and 1988 and covered 24 inlets. This dataset contains the results of a survey of Milford Haven and the estuary of the Rivers Cleddau (Daugleddau estuary). The purpose of this dataset was to describe areas in terms of their physical attributes; to review the results of previous studies; to review marine resource usage e.g. fisheries, diving activites etc; to catalogue available information and, to collect information and photographs on the habitats and species present. The field survey specifically aimed to collect further information on habitats and species where little or no previous work had been carried out, in areas of known or likely nature conservation importance, or where rare or unusual species may be present. 19870228
