Otter (Lutra lutra) populations have been recovering in the UK and expanding into new and often isolated
habitats. Otters were first sighted at Malham Tarn in 2009, and have since been observed on a regular basis.
This study looks at the diet of the Malham Tarn otters and considers their possible impact on prey
populations, such as fish, wading birds and white-clawed crayfish
