Chapter 20 - Peat Fires in Ireland

Peatlands are one of Ireland's most characteristic natural features, making up about 17% of the Irish landscape. Their formation began at the end of the last glaciation (about 11,700years ago) and was initially confined to shallow lakes and wet hollows. However, over time there was a transition from open water to fen and then acid ombrotrophic raised bogs. Blanket bog also spread over extensive areas of poorly drained land in the uplands and western seaboard. This spread may have taken place in areas as early as 7000years ago but was more widespread by 4000years ago when the climate may have become wetter. Ireland's peatlands have been exploited for fuel over the last 400years, reducing the original extent of the peatland by almost 47%
