Lough Hyne, is close to Skibbereen in West Cork. It is 0.8km by 0.6km and was likely to have originally been a freshwater lake until approx 4000 years ago when rising sea levels flooded it with saline ocean water. The lake is now fed by tidal currents that rush in through Barloge Creek in a stretch known as ‘The Rapids’. In 1981 Lough Hyne became Ireland’s first Marine Nature Reserve and remains the only one. A Marine Nature Reserve is a conservation designation officially awarded by a government to a marine reserve of national significance. Lough Hyne has an unusual habitat of highly oxygenated yet warm seawater; consequently a wide biodiversity is sustained in various environmental conditions. Scientific research began in 1886 when William Spottswood Green recorded the presence of purple sea urchin, Robert Lloyd Praeger visited later in the 19th century and UCC’s Louis Renouf founded the biological station in 1923. Scientific study has been ongoing ever since by JA Kitching, FJ Ebling, Dan Minchin to name a few. Issues concerning the Lough more recently have been the collapse of the western wall at the Rapids, which was built as a Famine relief effort in the 19th century, due to erosion. However since 2006 a Heritage Council Biodiversity grant was awarded to Dr Rob Allen to rebuild the Rapids wall and reclaim the land where one of the on-site laboratories was.
