Celtic Rainforest is a colloquial term which refers to the temperate rainforest of Ireland and Great Britain. These woodlands are also variously referred to as Atlantic rainforest, Upland Oakwoods, Atlantic Oakwoods or Western Oakwoods. Today, the Celtic Rainforest exists as small fragments of the temperate rainforest that once covered much of Ireland and the west coast of Great Britain. The majority of these fragments occur on steep-sided slopes above rivers and lakes which have avoided clearance and intensive grazing pressure. There are notable examples in Scotland on the islands and shores of Loch Maree, Loch Sunart, Loch Lomond, and one of the best preserved sites on the remote Taynish Peninsula in Argyll. In Wales, they occur on steep-sided riverine gorges in Snowdonia and Mid Wales.
