Deddf yr Amgylchedd (Cymru) Adran 7 ac OSPAR: Cynefinoedd Morol

  • English

  • All

Under the Environment (Wales) Act (2016), Section 7 requires biodiversity lists to be produced. These lists include types of habitats which are of 'Principal Importance' for the purpose of maintain and enhancing biodiversity in relation to Wales. This list supersedes the duty in Section 42 of the NERC Act 2006. In addition to this marine habitats can be protected under the OSPAR Convention, which has established a list of 'threatened and/or declining species and habitats' in the North-East Atlantic.


This spatial dataset details the extent and location of those marine habitats classed of 'Principal Importance' under Section 7 and are regarded as 'threatened or declining' under OSPAR in Wales.


Habitats include: Carbonate Reefs, Estuarine Rock, Honeycomb Worm Sabellaria alveolata, Intertidal Underboulder, Mud habitats in deep water, Musculus Discors Green crenella Beds, Blue Mussel Beds (listed under OSPAR aswell), Fragile Sponge and Anthozoans (listed under OSPAR aswell), Horse Mussel Modiolus Bed (listed under OSPAR aswell), Intertidal Mudflats (listed under OSPAR aswell), Maerl Beds live and dead (listed under OSPAR aswell), Sabellaria spinulosa reef (listed under OSPAR aswell), Saline Lagoons (listed under OSPAR aswell), Saltmarsh, Seagrass Beds (listed under OSPAR aswell), Seapens And Burrowing Megafauna (listed under OSPAR aswell), Peat Clay Exposures (listed under OSPAR aswell), Sheltered Muddy Gravel (listed under OSPAR aswell), Subtidal Mix Mud Sediments (listed under OSPAR aswell), Tide Swept Channels (listed under OSPAR aswell), Oyster Beds (OSPAR only).

O dan Ddeddf yr Amgylchedd (Cymru) (2016), mae Adran 7 yn ei gwneud yn ofynnol i restrau bioamrywiaeth gael eu cynhyrchu. Mae'r rhestrau hyn yn cynnwys mathau o gynefinoedd sydd yn "Bwysig Iawn" at ddiben cynnal a gwella bioamrywiaeth mewn perthynas â Chymru. Mae'r rhestr hon yn disodli'r ddyletswydd yn Adran 42 o Deddf yr Amgylchedd Naturiol a Chymunedau Gwledig 2006. Yn ogystal â hyn, gellir gwarchod cynefinoedd morol o dan Gonfensiwn OSPAR, sydd wedi sefydlu rhestr o "rywogaethau a chynefinoedd dan fygythiad a/neu sy'n dirywio" yng Ngogledd-ddwyrain yr Iwerydd. Mae’r set ddata ofodol hon yn manylu ar helaethrwydd a lleoliad y cynefinoedd morol hynny sydd wedi’u dosbarthu fel “Pwysig Iawn” o dan Adran 7 ac sy’n cael eu hystyried yn rhai “dan fygythiad neu’n dirywio” o dan OSPAR yng Nghymru. Ymhlith y cynefinoedd mae: Creigresi Carbonad, Creigiau Morydol, Mwydyn Crwybr Sabellaria alveolata, Clogfeini Rhynglanwol, Cynefinoedd mwd mewn dyfroedd dyfnion, Gwelyau Misglod Gwyrddion Musculus Discors, Gwelyau Cregyn Gleision (a restrir o dan OSPAR hefyd), Sbwng Bregus ac Anthosoaid (a restrir o dan OSPAR hefyd), Gwely Marchfisglod Modiolus (a restrir o dan OSPAR hefyd), Fflatiau Llaid Rhynglanwol (a restrir o dan OSPAR hefyd), Gwelyau Maerl byw a marw (a restrir o dan OSPAR hefyd), riff Sabellaria spinulosa (a restrir o dan OSPAR hefyd), Lagwnau Heli (a restrir o dan OSPAR hefyd), Morfa Heli, Gwelyau Morwellt (a restrir o dan OSPAR hefyd), Megaffawna Seapens a Thyrchu (a restrir o dan OSPAR hefyd), Datguddiadau Clai Mawn (a restrir o dan OSPAR hefyd), Graean Mwdlyd Cysgodol (a restrir o dan OSPAR hefyd), Gwaddodion Mwd Cymysgedd Islanwol (a restrir o dan OSPAR hefyd), Sianelau wedi’u Hysgubo gan y Llanw (a restrir o dan OSPAR hefyd), Gwelyau Wystrys (OSPAR yn unig).

Lineage

The data was collated from a wide range of sources, including but not limited to Marine Recorder, Phase 1 Intertidal, HabMap and Marine Monitoring Data. Habitats layers were produced as both polygon and point data for many of the habitats (where both types of data exist – some layers only have point data). Each layer is accompanied by processing notes detailing data sources and all decision made in creating the layers. A standard template was also produced and documented for attributing the GIS layers and general assumptions that could be made. Data layers within this dataset are updated at different times, usually as and when new data is available and collated.
