|Loch Roag Lagoons is a complex of silled lagoons illustrating the range of variation from freshwater to marine conditions on the Atlantic coast of the Hebrides. Tòb Valasay has a complex salinity regime, determined by the balance between fully marine water introduced over the sill and freshwater from run-off and small inlet streams. Its basins contain a diverse range of habitats, including rocky outcrops, boulders and muddy sand, with softer mud in the eastern basin, and boulders, cobbles and shell-gravel in the narrows. A range of communities are present, including beds of eelgrass Zostera spp. and tasselweed Ruppia spp., turfs of marine algae and stands of large brown algae. Loch Shader is a smaller lagoon that is mainly brackish in character. It has soft, sheltered mud and sand sediments, with some boulders and cobbles on the shore and in shallow water. These substrates support a characteristic range of species. The narrows consists of a bedrock and boulder sill, supporting a more diverse community with a variety of species, including kelp Laminaria spp., anemones and sponges.|
