Caledonian Forest

Caledonian Forest above the Allt Ruadh

The Caledonian Forest is a type of woodland that once covered vast areas of Scotland. Today, parts of the original forest survive, covering 180 square kilometres (44,000 acres) in 84 places. The forests are home to a wide variety of wildlife, much of which is not found elsewhere in the British Isles.

History

The Caledonian forests were formed at the end of the last ice age. Trees began to recolonise what is now the British Isles over a land bridge which is now beneath the English Channel. Forests of this type were found all over what is now the island of Great Britain for a short period. Then the climate began to warm and the pine wood retreated north into the Scottish Highlands.

What's left of a Caledonian pinewood near Loch an Eilein

The native pinewoods which formed this westernmost outpost of the boreal forest of Europe are estimated to have covered 15,000 km² (3,700,000 acres) as a vast wilderness of pine, birch, rowan, aspen, juniper, oak and a few other species. On the west coast, oak and birch predominated in a temperate rainforest ecosystem rich in ferns, mosses and lichens.

The forest takes its name from the Romans, who called Scotland Caledonia, from the early Celtic word '*caleto-' meaning 'hard, strong'. The name was used by a local tribe or tribal confederation of native Picts or Britons called the Caledonii.

Rewilding

Today less than 1% of the original native pinewood forest survives, in isolated remnants. The only real future of the once great forest is rewilding. This amounts to keeping sections free of deer and hogs until trees have a chance to grow. Natural predators are also needed to keep control of herbivores which would otherwise eat everything before trees could grow. Alan Watson Featherstone explains his life's work.

Wildlife
