Electrofishing Surveys

The Foundation, along with partners the Environment Agency and Natural Resources Wales, conduct yearly electrofishing surveys throughout the Wye and Usk catchments to record fish densities. This is vital information in helping us assess the health of the catchments.

    Catchment Systems Thinking Cooperative (CaSTCo)

    Only 14% of rivers in England are in ‘good health’ – one of the worst records in Europe. This project will ensure there is robust evidence base for tackling environmental challenges with direct support for local evidence gathering and community engagement in eight demonstration catchments, and a national framework of standardised tools and training.

  • Senior Monitoring Team Field Technician

    WUF requires a senior monitoring technician role to support a variety of projects we undertake. This role will be able to work across different departments to support the delivery of multiple projects and staff.
