Rivelin Valley Conservation Group and Ruskin in Sheffield
The mill dam at Mousehole was one of the largest in the valley but since the forge closed in the 1930s the mill dam has become well-colonised by trees such as Ash, Alder, Elder, Sycamore, Holly, Hawthorn, Elm and Willow. At the time of writing (2015), there is a large amount of the invasive species Himalayan Balsam here. Look and listen out for birds such as Blackbird, Chiffchaff, Robin, Thrush, Wren and tits including Blue, Great and Long-tailed.
Just above the Mousehole weir (about 300 m upstream from the gates to Mousehole Forge), there is a steep wooded bank on the north-west side of the river. Here there are several large Oaks at the top the bank - a favourite early morning haunt for the Great Spotted Woodpecker. Brambles, ferns, ivy and liverworts grow on the damp rocky outcrop. Watch out for a Kingfisher on this stretch of the river.
