Marine intertidal Phase 1 Final Report and Analysis Data dataset https://portal.medin.org.uk/portal/start.php?tpc=007_NRW_DS109830 This dataset contains analysis data in the form of excel spreadsheets (survey dates, contacts, recreational popular areas, details of sea defences etc) and MapInfo tables (biotope distribution- including rare, scarce, nationally important and specialised biotopes, biotope richness, mapping of northern and southern species, non native species, LBAP areas, bait digging and boulder turning locations, angling, man made substrata, intertidal designated sites etc). It also contains many images taken during surveying which are stored as JPEGs. These are made up of the results of a 10 year survey of the intertidal zone of Wales including detailed information on a wide variety of features and activities e.g. the distribution of habitats and species, non-native species, man-made substrata, bait collection. It provides comprehensive baseline data for monitoring change or for the identification of locations sensitive to certain anthropogenic impacts - a critical capacity in the context of climate change. The data also provides information to support a notification programme for intertidal Sites of Special Scientific Interest (SSSI), thereby providing a series of intertidal designated sites across Wales. It also underpins the selection of the internationally important Special Area of Conservation (SAC) site series. Intertidal mapped data provides an integrated information resource for Local Authority structure and development plans on the coast and for the consideration of planning applications. The maps give important regional information about habitat and biotope distribution. They are used in the production and evaluation of Environmental Impact Assessments, assessment of sites as possible Sites of Special Scientific Interest (SSSI), as a basis for the development of sensitivity mapping, and as a baseline for developing monitoring of intertidal features in marine Special Areas of Conservation (SAC). Sites are mapped once and therefore are a 'snapshot' in time. 20070228
