Rannoch Moor is a large expanse of around 30 square miles (78 km²) of boggy moorland to the west of Loch Rannoch, in the Watsonian Vice County of Mid Perth and the County of Perthshire, in Scotland.
It is notable for its wildlife, and was frequently visited by Horace Donisthorpe, who collected many unusual species of ants on the moor and surrounding hilly ground. Today it is still one of the few remaining habitats for Formica exsecta, the narrow-headed ant, although recent surveys have failed to produce any sign of Formica pratensis, which Donisthorpe all recorded in the area in the early part of the 20th century.
Peat deposits pose major difficulties to builders of roads and railways. When the West Highland Line was built across Rannoch Moor, its builders had to float the tracks on a mattress of tree roots, brushwood and thousands of tons of earth and ashes.
