Description

Knapdale Lochs Knapdale Lochs SSSI is comprised of a group of four small upland lochs in the Knapdale area of Argyll. These are Dubh Loch, Loch Clachaig, Loch Fuar-Bheinne and Loch nan Torran. Knapdale Lochs SSSI supports a nationally important breeding population of black-throated diver Gavia arctica. The lochs are all located within an altitudinal range of 220-420 metres above sea level and are nutrient poor (oligotrophic) with characteristic emergent and aquatic flora. These lochs provide breeding sites for the black-throated diver, a rare breeding species in Britain confined to the north and west of Scotland. The SSSI supports over 2% of the UK black-throated diver population. Knapdale Lochs are also the most southerly black-throated diver breeding territories in Britain and have a higher than average productivity. The combination of high productivity and location at the edge of the European range make this site extremely valuable to the maintenance of the British population.
