Priority Marine Habitats of Wales: Saline Lagoons
UK Biodiversity Action Plan (BAP) priority habitats cover a wide range of semi-natural habitat types, and were those that were identified as being the most threatened and requiring conservation action under the UK Biodiversity Action Plan (UK BAP). The UK BAP habitats and species lists have been used to draw statutory lists of priority habitats as required under Section 42 of the Natural Environmental and Rural Communities (NERC) Act 2006. The habitats listed as priority habitats include; blue mussel beds, Fragile sponge and anthozoan communities, Tide swept channels, Horse mussel beds, Maerl beds, Honeycomb worm reefs, Seagrass beds, Oyster beds, Intertidal boulder communities, Intertidal mudflats, mud habitats in deep water, Sheltered muddy gravels, subtidal mixed muddy sediments, Estuarine rocky habitats, Peat and clay exposures, Carbonate reefs, Musculus discors beds, Saline lagoons, Coastal Saltmarsh and Subtidal sands and gravels. The data is related to Saline Lagoons only. Lagoons in the UK are essentially bodies, natural or artificial, of salinewater partially separated from the adjacent sea. They retain a proportion of their seawater at low tide and may develop as brackish, full saline or hyper-saline water bodies. Lagoons can contain a variety of substrata, often soft sediments which in turn may support tasselweeds and stoneworts aswell as filamentous green and brown algae. In addition lagoons contain invertebrates rarely found elsewhere. They also provide important habitat for waterfowl, marshland birdsand seabirds. The flora and invertebrate fauna present can be divided into three main components: those that are essentially freshwater in origin, those that are marine/brackish species and those that are more specialist lagoonal species. The presence of certain indigenous and specialist plants and animals make this habitat important to the UK's overall biodiversity. Majority of the records are from the 1960s onwards. This data is still in draft format and has not yet been finalised. All habitat records include a confidence measure. Decisions about how these were applied are documented in the processing notes for each habitats.

The data was collated from a wide range of sources, including but not limited to Marine Recorder, Phase 1 Intertidal, HabMap, Marine Monitoring Data. Habitats layers were produced as both polygon and point data for many of the habitats. Each layer is accompanied by processing notes detailing data sources and all decisions 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. The habitat layers build on and replaced work started in the CCW BAP Atlas.
