Annex I habitats that are a primary reason for selection of this site
Loch of Isbister is an excellent example of a shallow moderate-sized naturally eutrophic loch. Formerly the Loch of Isbister was more extensive, but encroachment by peripheral vegetation and peat has resulted in the development of a high-quality basin-mire complex, with excellent examples of open-water transition plant communities. The loch supports a rich plant flora typical of the Magnopotamion type, with plants able to grow in the centre of the loch due to its shallow nature, including abundant stoneworts Chara spp. and pondweeds Potamogeton spp. The loch is rich in northern species and is the most northerly site for natural eutrophic lakes in the UK.
