The Exmoor ponies who have become 'eco warriors'

Two Exmoor ponies introduced to the heart of the Yorkshire Dales have been described as “eco warriors” by organisers of a conservation project. The pair – called Reddycombe and Cannerhaugh – have been moved to Malham Tarn as part of a scheme to help control invasive plants running wild in one of the UK’s most precious habitats for wildlife.
