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

3130 Oligotrophic to mesotrophic standing waters with vegetation of the Littorelletea uniflorae and/or of the IsoŽto-Nanojuncetea
Loch Ussie in the north-east Highlands lies in a shallow basin of Old Red Sandstone rocks and is one of the best mesotrophic lochs in Scotland. The distribution of natural mesotrophic lochs in Scotland is restricted, occurring most commonly at the junction of upland and lowland areas where the geochemical characteristics of these areas are manifested in the one waterbody. This gives rise to water quality conditions which allows the flora and fauna of upland and lowland areas to thrive. Water quality data show that Loch Ussie has a neutral pH and is moderately rich in nutrients, and a comparison with historical conditions show that it has changed little in the last 100 years. The assemblage of water plants is very diverse with nine pondweed Potamogeton species present, including the rare Shetland pondweed Potamogeton rutilus. The fringing sedge beds and shore support such species as bladder-sedge Carex vesicaria and pillwort Pilularia globulifera.
