Loch Garry (Dalnaspidal)Loch Garry is a large upland freshwater loch located in Perth and Kinross in Scotland, within the Forest of Atholl just to the south of the Cairngorms National Park.Loch Garry ProjectA study of the arctic char population of the loch conducted by Ron Greer between 1972 and 1974 concluded that it had become ecologically impoverished as a result of the loss of living and dead plant material from the shallow littoral zone. In 1986, the Loch Garry Project was established to undertake a programme of tree-planting around the loch.
