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

3150 Natural eutrophic lakes with Magnopotamion or Hydrocharition - type vegetation
Llyn Dinam is a coastal eutrophic lake in north Wales. Common reed Phragmites australis, and to a lesser extent common club-rush Scirpus lacustris ssp. lacustris, dominate the shoreline. Rigid hornwort Ceratophyllum demersum is abundant in shallow open water, often in association with autumnal starwort Callitriche hermaphroditica and ivy-leaved duckweed Lemna trisulca. The white and yellow water-lilies Nymphaea alba and Nuphar lutea dominate in a sheltered arm on the west side. Fennel-leaved pondweed Potamogeton pectinatus, perfoliate pondweed P. perfoliatus and lesser pondweed P. pusillus have been recorded. Stoneworts Chara spp. are present. Water chemistry characteristics are consistent with those expected in eutrophic lakes, including relatively high pH, alkalinity and phosphorus levels. Llyn Dinam is the least-enriched of a series of Anglesey Lakes which have been subjected to sediment diatom analysis
