|Loch a’ Phuill is a large (96 ha) high-quality naturally eutrophic loch situated behind an extensive machair complex of windblown sand and is backed by a raised beach, forming its northern shore. It is located in the south-west corner of the island of Tiree. Loch a’ Phuill is one of the best examples of a coastal eutrophic loch, with a catchment including acid grassland/heathland on peaty soils and machair landforms protecting it from any serious modifications. The loch supports a particularly diverse aquatic plant flora with several species indicative of the sandy substrate and maritime influence on this eutrophic waterbody, particularly in its south-west area that is dominated by stoneworts Chara spp. The loch also supports several species of pondweed including the nationally scarce fen pondweed Potamogeton coloratus, and slender-leaved pondweed P. filiformis. Of further interest is the loch’s very high pH level, indicating the liming influence of windblown shell-sand, and high conductivity reflecting sea-water spray affecting the site.|
