Darren Tansley has been working with the Wildlife Trusts since 2005, as a mammal ecologist and freshwater specialist, but his voluntary conservation work goes back to the 1988 phocine distemper outbreak that killed thousands of seals across the North Sea. As part of his River Catchment work at Essex Wildlife Trust he coordinates the Combined Essex Catchment Partnership and is currently working on a fish migration roadmap with the Thames Estuary Partnership, the Essex beaver release trial and an innovative new eDNA technique for monitoring mammal species in river catchments in conjunction with Salford University.

In 2014 he co-authored the Mammals of Essex and was also invited to represent the Wildlife Trusts on the UK Water Vole Steering Group which coordinates the UK response to water vole issues from The Environment Agency, Natural England, Scottish Natural Heritage, Natural Resources Wales, RSPB, The Wildlife Trusts and PTES (the People’s Trust for Endangered Species). During this time he helped design the new National Water Vole Monitoring Programme, supported the publication of the Water Vole Mitigation Handbook and coordinated the catchment scale reintroduction of water voles to the River Stort. In 2016 he was invited to chair the UK Water Vole Steering Group, taking over the role filled for 20 years by the Environment Agency’s National Biodiversity Manager, Alastair Driver.
