Annex I habitats that are a primary reason for selection of this site

  • 3150 Natural eutrophic lakes with Magnopotamion or Hydrocharition - type vegetation

    Llangorse Lake is the largest lake in south Wales and is an example of a northern or western natural eutrophic lake of glacial origin, in this case lying on Old Red Sandstone. The flora is dominated by pondweed – yellow water-lily Potamogetonaceae – Nupharetum associations, and the shoreline flora is a good example of the club-rush – common reed Scirpo – Phragmitetum association. Llangorse Lake has a different flora from that of Loch Watten, the other lake of this type selected, being richer in more southern elements such as shining pondweed Potamogeton lucens.
