About the reserve

Dolydd Hafren is the largest area of unmodified river floodplain in Montgomeryshire. Over time, the unstoppable power of water has created a mosaic of oxbows, shingles, wet meadows, reedbeds, scrub and willow and, of course the river itself.

The team at Montgomeryshire Wildlife Trust have enhanced the sites' natural assets through careful management, creating species-rich hedgerows, woodland and scrub. Each year, an area of the reserve is planted with arable crops to provide a giant bird table, as well as encouraging arable weeds.

The great diversity of habitats on this natural floodplain provides for a wealth of wildlife from the rare, inconspicuous Mudwort to the frequently spotted Brown Hare; and if birds are your thing, then Dolydd Hafren is hard to beat!

With such a diversity of species, there is plenty to see at Dolydd Hafren all year round. Migration season in Spring and Autumn can be the most exciting time; you never know what you might see!

For up to the minute bird sightings at Dolydd Hafren, the Montgomery Bird Blog is a great place to start:
