Habitat Mapping for Conservation and Management of the Southern Irish Sea (HABMAP)
The HABMAP project was set up in response to the need for better spatial awareness of habitat distributions in the Southern Irish Sea. This work produced habitat maps of the seabed using novel predictive modelling techniques. This dataset is related to the predictive modelling only.
The HABMAP Extension Project has built on the methods developed during the original project, and has repeated the modelling work using higher resolution / improved input datasets to help increase the accuracy of the predictive map outputs. The modelling work has also been extended to cover all of Welsh waters (previously cut-off at the Interreg funding boundary), notably including the Dee and Severn estuaries.
The purpose of this data capture was to provide seabed habitat maps that could be used for conservation and management. Project outputs might be used in strategic planning, decision making for offshore developments, Marine Protected Area selection, sensitivity mapping and mapping essential fish habitats. However, because of the way the has been produced, and the fact that some data has been modelled and derived, the maps are not appropriate to act as the sole evidence for any specific planning or regulatory decision or assessment without further supporting studies or evidence.
The project boundaries were as follows: Southern Irish Sea- land-based boundaries include the whole Welsh coast to the English border on the east side of the Dee Estuary in the north, and the whole Severn Estuary and Bristol Channel coastline in the south, extending as far as Morte Point (east of Ifracombe) in England. The southern project boundary then extends offshore (skirting the northern tip of Lundy) across to a point approximate 60km west of Waterford on the Irish coast, including the whole SE Ireland coastline and offshore banks as well as parts of the Celtic Sea. The boundary then extends northwards along the Irish coast to a point approximately 40 km north of Dublin.

The HABMAP project used a multi-parameter predictive modelling tool to develop seabed biotope maps for the Southern Irish Sea. Existing biological and physical datasets across the whole study area were collated within a Geographical Information System (GIS) and used to construct a rule-based biotope prediction model. Data were collated for the following physical parameters: bathymetry, sediment type, temperature, wave stress, tide stress, salinity and light attenuation. (NB Bedform data was not included in the extension project modelling work as it was found to be unreliable during the original project). These data were combined in GIS to produce a single map with many cells, each with a value for each of the physical parameters. Data was also collated for seabed biotopes and these points were overlain onto the physical data layer, allowing the relationships between each biotope and the physical environment to be determined. Preference ranges of each physical parameter were then identified for each biotope, leading to the development of predictive rules that could identify other cells with the same physical data ranges. This meant that maps could be produced showing the recorded and predicted distributions for each biotope. A final map was produced which listed all recorded and predicted biotopes in each cell, in order of confidence.

-
The data used to create the model output is knows as Input data parameter maps. These have restricted access. The British Geological Society (BGS) derived seabed sediment map; Temperature data was provided by the Met Office; Bathymetry layer derived from Seazone hydrospatial dataset. Tidal and wave dataset were supplied by ABPmer (for DEFRA data layers project). There is a need to check the conditions of use before dissemination.
The datasets will not be loaded to DataMapWales as individual layers with endpoints as the data is too complex and needs to be viewed as a package. It will remain as ShareFile link only
