England’s largest temperate rainforest is set to become a protected nature reserve.

The Borrowdale Valley in Cumbria was declared a national nature reserve by Natural England and the National Trust on Wednesday.

This means the 721-hectare National Trust site has been marked out as an area of focus for conservation and nature restoration efforts

Once abundant in the UK because of the oceanic climate, temperate rainforests now cover less than 1% of England’s surface.

Borrowdale, which is as wet as a tropical rainforest albeit much cooler, regularly sees the highest rainfall in England.
