This layer forms one of a set of data layers created for the Defra MB0102 contract. This work will support the delivery of a network of Marine Protected Areas as required to meet existing international and national obligations and commitments, including Marine Conservation Zones (MCZs), a new measure to be delivered as part of the Marine and Coastal Access Bill, and equivalent measures under Scottish legislation. The availability of these data layers will also be of importance in underpinning Marine Planning (e.g. licensing) in our marine area.

Data was collated from a range of conservation and academic organisations and through a literature search. The survey used to collate the polygon data are: MPALAYERS000025 - Braint Estuary pSAC: NVC Saltmarsh Survey 1996 MPALAYERS000026 - Cefni and Aberffraw Estuaries pSAC NVC Saltmarsh Survey 1998 MPALAYERS000027 - Burry Inlet and Loughor Estuary MPALAYERS000028 - Taf, Tywi and Gwendraeth saltmarsh Survey 1997 MPALAYERS000029 - Milford Haven Saltmarsh Survey 2002 MPALAYERS000030 - Milford Haven Saltmarsh Survey 2002 MPALAYERS000031 - Milford Haven Saltmarsh Survey 2002 MPALAYERS000032 - Milford Haven Saltmarsh Survey 2002 MPALAYERS000034 - National Vegetation Classification Survey: Saltmarsh of the Conwy Estuary, September 2001 MPALAYERS000035 - NVC Survey of the saltmarshes of the lower Dyfi Estuary 1996.

Original Scientific Name: The scientific name (or in some cases the common name) recorded in the original survey. Scientific Name: The current accepted name for the taxon using WORMS as the definitive species list. See link: www.marinespecies.org Survey ID: A link to survey information. Where data is entered in to Marine Recorder this refers to the MR SurveyID. A few surveys could not be entered into Marine Recorder without risk of duplication occuring. e.g. Seasearch data that will be entered into MR at a later date, data from polygons etc. These have been given a project surveyID using the reference: MPALAYERS0000XX Date: The date the species was recorded. Vague dates have been entered as the first of a month, if only the month is known, e.g. 01/03/89 or as the first of January if only the year is known, e.g. 01/01/78. Unknown dates show as 00:00:00. Location Name: The location or site name where provided. SampleID: For Marine Recorder surveys the sample_key field has been entered. Event name: Where known an event name has been provided. Latitude: The latitude of the sample point. Longitude: The longitude of the sample point. Determiner: Where known the determiner of the species record as specified in Marine Recorder. For non MR surveys the recorder has been inputted into this field as it has been assumed that the recorder is the determiner unless otherwise stated. Status: The species status as defined by three terms; Present - the default indicating the presence of a species. Absent - Absence records have only been included in a small number of cases where a key historical population has disappeared. Uncertain - Indicates that the identification of the species may be incorrect and further investigation is required. Coordinate Precision: An estimate of the spatial resolution in metres of the co-ordinate, based on survey method, date and the derivation of the co-ordinates . This ranges from 10-10000 metres. EndDate: A second date field has been added to this layer to accomodate records organized into date classes from the BSBI. As several of the date classes are quite large it was decided to display this information so as records are not misinterpretted.
