One of the oldest holly groves in Europe is to be found on the Stiperstones in Shropshire.
The Hollies nature reserve is a cluster of around 500 gnarled and wizened trees that were planted about 400 years ago.
The reason the trees have survived into the 21st century is because their leaves were harvested by lead miners to feed to their livestock.
The upper branches were cut back to encourage new growth, which produced nutritious, prickle-free leaves that helped animals survive the harsh winters on this bleak hillside.
Today, the miners and their families are long gone, but their enduring legacy is in the safe hands of Shropshire Wildlife Trust.
