Water Vole

Water Vole

Some widespread mammals such as water vole, otter, hazel dormouse and badger are protected by law; others, such as hedgehog and brown hare, are Species of Principal Importance under Section 41 of the NERC Act. These species all require appropriate consideration in planning applications. Our ecologists have considerable mammal expertise, and are adept at carrying out surveys and specifying mitigation methods for protected and valued mammal species. Our skills working with  non-protected species such as small mammals (shrews and rodents) and others may be of assistance in site monitoring and management.

Water vole survey

Water vole survey

Project Example – Riparian Mammals

As part of ongoing Environment Agency river restoration works, WFE has undertaken surveys for protected water vole and otter along multiple sections of the River Wensum SAC. These were carried out alongside habitat surveys and targeted surveys for bats and badgers.

The riparian mammal surveys focused primarily on the main river channel, and often involved a finger-tip search of the banks. Our survey results and impact assessments were used to inform restoration designs and mitigation protocol. Once restoration works were complete, further surveys have been conducted to determine the success of the project.

WFE provided protected species surveys and reports leading to the successful planning consent at Middlewick Wind Farm in Essex.  We then provided ecological clerk of works during the construction phase of the project. This included excluding water vole from areas of impact and applying for a Natural England licence to close a badger sett. The badgers were relocated and the turbines constructed. We are now overseeing the installation of a range of ecological enhancements and conducting post construction monitoring at the site.
