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

  • Bosherston Lakes are an outstanding shallow marl lake system created at intervals in the late 18th and mid 19th centuries by damming a limestone river valley. They are fed in part by a series of calcium-rich springs and are isolated from the sea by a small sand dune ridge. Charophytes are represented by bristly stonewort Chara hispida which forms dense beds up to 1 m high, with individual plants up to 3.5 m long, and by variable quantities of C. globularis, C. virgata and C. vulgaris. Extensive white water lily Nymphaea alba beds also occur, mainly in the western and central arms. In contrast, the eastern arm is characterised by variably dense stands of curled pondweed Potamogeton crispus, fennel pondweed Potamogeton pectinatus, spiked water-milfoil Myriophyllum spicatum and Canadian waterweed Elodea canadensis. Emergent vegetation fringes parts of the system, mostly common reed Phragmites australis, bulrush Typha latifolia, common spike-rush Eleocharis palustris and branched bur-reed Sparganium erectum.

Annex II species that are a primary reason for selection of this site

  • 1304 Greater horseshoe bat Rhinolophus ferrumequinum

    This site in south-west Wales supports approximately 9.5% of the UK greater horseshoe bat Rhinolophus ferrumequinum population. It represents the species at the north-western extremity of its range. The site contains a mixture of maternity, transitory and hibernation sites and so demonstrates good conservation of features required for survival.
