A number of people have recently said that they have not seen any water voles in the brook.
However there is evidence of water vole burrows and latrines in the section between Ashbourne Road and Oakamoor Road. A recent survey in the summer of 2018 has located 11 latrines in this section with a further 5 in the area behind Ullswater Drive. A number of water voles have been seen by members, particularly in the middle section of the reserve. Unfortunately there has been no evidence of water vole activity south of Ashbourne Road.
As part of the planning application for the old JCB site a survey also recorded the presence of water voles in this area.
