2005 English Nature (EN) North West England. Maritime monitoring intertidal survey dataset https://portal.medin.org.uk/portal/start.php?tpc=010_39e1786111ee57e2de8c7408789d4acf Maritime monitoring surveys were undertaken on behalf of English Nature in order to fulfil the requirements of the European Habitats Directive to assess the ecological condition of the designated features within the Natura 2000 site series. For this contract, intertidal surveys were undertaken of mudflats, sandflats and cobble skears in selected areas of Morecambe Bay, the Lune Estuary, the Wyre Estuary and the Ribble Estuary. The surveys were carried out along a series of transects positioned to encounter the widest possible ranges of biotope and also to facilitate comparison with historical data. A range of data were collected along each transect, including information on sediment character, infaunal community, saltmarsh condition and anthropogenic influences. Recommendations for future surveys include the provision of an up-to-date set of aerial photos (at low water) in order to take into account any channel movements when positioning transects. 20060301 20051021
