Exmoor supports the strongest sub-population of Red deer in England. There are over 300 Red deer living on the Holnicote Estate.
You can often see deer on Ley Hill above Porlock, and around the edges of Horner Wood.
Look out for the Exmoor ponies. They help to maintain the moorland habitat of Exmoor.
They act as a team of lawn mowers, keeping the grass short and eating scrub.
