Càrna is an island in Loch Sunart, an arm of the sea, close to the Ardnamurchan peninsula, on the west coast of Scotland.GeographyCàrna lies across the mouth of Loch Teacuis, forming two narrow kyles which provide some of the trickiest rock-dodging for yachtsmen anywhere on the west coast. Moine schist bedrock of quartz-feldspar constitution, with mixed schists and mica schists in a west coastal strip. A north-south ridge divides the island in two. From the heather covered rocky peak of Cruachan Chàrna, there are spectacular views over Oronsay, Loch Sunart, Morvern, Coll and Isle of Mull.WildlifeA variety of habitats support willow warblers, redstarts, wheatears, whinchats, twites, herons, ostercatchers, cormorants, ravens and kestrels. There are also eagles here, including occasional sea eagles. Eilean nan Gabhar (goat island) to the south is often used by seals, and there are also porpoises in the area.In 2013 it was announced that Càrna is to become a sanctuary for wildcats in order to protect the species, which is endangered in Scotland. A new breeding centre will be run by The Aspinall Foundation and a separate project on the mainland will involve the trapping and neutering of feral cats. Purebred wildcats reared on the island will be released into the wild.
