Mapio cynefinoedd ar gyfer gwarchod a rheoli de Mor Iwerddon (HABMAP)
Sefydlwyd prosiect HABMAP mewn ymateb i’r angen am well ymwybyddiaeth gofodol o ddosbarthiad cynefinoedd ym Môr De Iwerddon. Mae’r gwaith hwn wedi cynhyrchu mapiau o gynefinoedd gwely’r môr gan ddefnyddio technegau modelau rhagfynegol arbennig. Mae Prosiect Ymestyn HABMAP wedi adeiladu ar y dulliau a ddatblygwyd yn y prosiect gwreiddiol, ac yn ailadrodd y gwaith modelu gan ddefnyddio cydraniad uwch / gwell setiau data mewnbwn er mwyn gwella cywirdeb y mapiau rhagfynegol. Mae’r gwaith modelu wedi’i ymestyn hefyd i ymdrin â holl ddyfroedd Cymru (pennwyd y ffiniau gwreiddiol yn ôl ffiniau cyllidol Interreg), gan gynnwys aberoedd afonydd Dyfrdwy a Hafren. Aethpwyd ati i gasglu’r data hwn er mwyn darparu mapiau o gynefinoedd gwely’r môr y gellid eu defnyddio er dibenion cadwraeth a rheoli. Mae’n bosibl defnyddio allbynnau’r prosiect hefyd ym maes cynllunio strategol, gwneud penderfyniadau ynghylch datblygiadau alltraeth, dethol Ardaloedd Morol Dan Warchodaeth, mapio sensitifrwydd a mapio cynefinoedd pysgodfeydd hanfodol. Fodd bynnag, oherwydd y modd y cynhyrchwyd y mapiau, ac oherwydd bod peth data wedi’i fodelu a’i ddeillio, nid yw’n briodol defnyddio’r mapiau fel yr unig dystiolaeth ar gyfer unrhyw gynllunio penodol neu benderfyniad neu asesiad rheoleiddio heb astudiaethau neu dystiolaeth ategol bellach.

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
