Britain’s rare rainforests are home to wildlife from eagles to the world’s largest slugs and lichen looks like dragon skin, say conservationists battling to save them.

The Woodland Trust has unveiled a list of 11 “weird and wonderful” species that make their home in and around temperate rainforests found in the south-west and north-west of England, Wales and Scotland.

The forests once covered a fifth of Britain, but they have been lost from all but 1% of land area in the face of felling, overgrazing and conversion to other uses, face ongoing pressures including invasive species and are more threatened than their tropical counterparts, conservationists say.
