Freshwater Bullhead Survey Data in Wales

Bullhead is listed under Annex II of the Habitat and Species Directive as a "species of community interest". Bullhead numbers have been declining across Europe in recent decades as a result of human activities. Bullhead is a designated feature on three Special Areas of Conservation (SACs) in Wales: River Dee and Bala Lake / Afon Dyfrdwy a Llyn Tegid; River Wye / Afon Gwy; River Usk / Afon Wysg. This survey records the presence and populations of the freshwater fish, Bullhead (Cottus gobio), within the River Wye and River Usk SACs in south-east Wales. Currently data is available for all three Special Areas of Conservation (See survey metadata for further details).
