Before the Habitats Directive, only four lagoons were at all well known in Ireland (Lady’s Island Lake, Tacumshin Lake, Lough Murree, Furnace Lough) and very few biological studies had been published. Under the obligations of the Directive, the National Parks and Wildlife Service (NPWS) of the Irish Government commissioned a series of surveys of coastal lagoons in Ireland in order to compile an inventory of lagoons in the country for selection of representative examples for designation as, or within, SACs. Surveys were carried out in 1996 (Good 1996, Good and Butler 1998, Hatch 1996, Hatch and Healy 1998, Healy and Oliver 1998, Oliver and Healy 1998). These surveys were summarised by Healy et al. 1997a,b,c. Further surveys were carried out in 1998 (Healy 1999a,b; Oliver 1999, Roden 1999, Good 1999, Good and Butler 2000). An inventory of approximately 100 lagoons was compiled as a result of these surveys and 36 of the higher conservation value lagoons were sampled over a 1-4 day period, depending on the size of the lagoon. More lagoons were sampled from 2002-3 as part of a PhD study (Oliver 2005, Roden 2004).

Provenance information The Inventory_of_Irish_Coastal_Lagoons_polygons.shp dataset was based on the lagoons identified in the Inventory of Coastal Lagoons 2007. Included in the inventory were sketch maps for each lagoon. However, due the scale and lack of background mapping these sketch maps could only be used as a reference tool in the creation of this spatial dataset. The OSi 1:5000 vector dataset was used as the basis for the creation of the Inventory_of_Irish_Coastal_Lagoons_polygons.shp dataset. The polylines from the OSi 1:5000 dataset, which corresponded to the extent of the lagoons were copied into a new lagoon polyline dataset. These polylines were then converted into a polygon dataset. In cases where the OSi 1:5000 vector dataset did not contain any spatial data for lagoons identified in the inventory, the OSi 2005 orthophotographs (1:40000) were used as the base layer to manually digitise the boundary of these lagoons. It should be noted that expert knowledge was used to correct instances where what was indicated on the OSi 1:5000 dataset did not match what was apparent on the ground from the orthophotographs. This dataset has been created using ArcMap 10. The source coordinate reference system is the Irish National Grid.
