Join us to discover the Irfon catchment's freshwater habitats

Do you want to discover more about the Irfon catchment’s freshwater habitats and wildlife? Book now for one of our spring 2026 events.

Through the River Irfon Catchment Project, we’re working with local farmers and landowners to reduce pollution and improve freshwater habitats for wildlife in the River Irfon catchment in mid-Wales. The Irfon stretches from Abergwesyn to Builth Wells, and the catchment includes many tributaries, floodplains, ponds and wetlands. These events are a great way to get involved in helping us protect this wonderful freshwater environment and the wildlife it supports.

For more details and to book your place at any of these events, please contact Paola Perez at Freshwater Habitats Trust: pperez@freshwaterhabitats.org.uk
