context_page_description: The Gearagh is a submerged glacial woodland and nature reserve two kilometres southwest of Macroom, County Cork, Ireland. It is located at the point where the River Lee descends from the mountains and widens at an alluvial plain, and stretches for roughly five kilometres, bounded by the townlands of Toonsbridge, Illaunmore and Anahala.
  It was until recently densely populated with ancient oak trees and the last surviving full oak forest in western Europe.
  Its Irish name, An Gaoire, is derived from the Irish word Gaorthadh, roughly the Wooden River. It was flooded in 1954 to facilitate the building of two hydro-electric dams in Carrigadrohid and Inniscarra, which provide electricity for the nearby city of Cork. The area is now part of the plants' upper reservoir. The development required the flooding of the region; consequently, hundreds of trees were felled and many people were relocated. Many of the trees were centuries old and had grown since the medieval period. Today only their stumps survive, in flood land, giving the area a ghostly and almost lunar appearance.
context_section_description: The Gearagh is primarily of interest and importance due to its rich and rare diversity of wildlife, and it represents the only extant extensive alluvial woodland in Western Europe. It hosts numerous rare plant species including marsh marigold, meadowsweet and nightshade, and 62 species of moss and liverwort. While oak and ash trees once pre-dominated, today there are a number of willow and alder trees on the higher islands and inlets. It hosts a large diversity of birds and wildfowl and attracts both summer and winter migrants. Examples include mallards, wigeon, Greylag geese, herons and coots. It also hosts Atlantic salmon and the near extinct freshwater pearl mussel. The area is protected under the international Ramsar Convention.
  The area has been the focus of significant heritage and conservation efforts, especially by environmental biologist and conservationist Kevin Corcoran. He observed that before the dam was built "this was the last pure stand of ancient riverine forest that had survived intact since the last ice age. This was just one of four such systems on the whole planet." Describing the Gearagh as of "immense" importance, Corcoran observed in a later interview how it is "hard to imagine what the area looked like before being flooded – a vast inland delta of inter-connecting, many branched streams that encircled a maze of small and inaccessible islands, covered in oak forest. It was protected from the ravages of humanity by its swampy terrain, deep swirling streams and treacherous banks of soft mud with holes big enough to swallow a horse."
  According to filmmaker Declan O’Mahony, "If the water level was permanently dropped, the Gearagh would grow back and has the full potential to become a world heritage site on a par with Newgrange, the Giant’s Causeway and The Burren". (The Burren is not actually a World Heritage Site, although it has been put forward as a candidate.).
  The Gearagh was declared a statutory nature reserve in 1987, under the protection of the Wildlife Act but owned by the ESB.
