Wicken Fen in Cambridgeshire is one of the few remaining fragments of England’s original fenland. A place loved by naturalists for generations, it was Victorian botanists and entomologists who led the efforts to ensure the land was entrusted to the National Trust, which has protected it for 125 years.

Today, Wicken Fen is a thriving mosaic of flowering meadows, sedge and reedbeds. It is one of the most species-rich areas in Britain, home to endangered species such as the crane, bittern, marsh harrier and great crested newt.

Martha Kearney explores the unique history and ecology of this remarkable landscape alongside sound artist Kathy Hinde. Together, they craft a handheld aeolian harp – a stringed instrument played solely by the wind. Kathy Hinde has created sound sculptures across Wicken Fen to celebrate 125 years of this special place, called 'Listen to the Voices of the Fen'.

Martha also meets local volunteer Gerard Smallwood, who demonstrates how the last surviving wooden windpump in the Fens, an iconic piece of machinery, is now used to re-wet the land. Ajay Tegala, a National Trust warden, shares recent wildlife sightings, offering a glimpse into the lives that flourish in this delicate ecosystem.
