Male osprey before return of female

Male osprey before return of female


From water-logged, tidal saltmarsh, through reclaimed grazing land and conifer plantation to current wildlife haven, Cors Dyfi has travelled an interesting journey. Since 1996, when the conifers were removed, work has been carried out to create and improve the natural and man-made habitats and increase the number of breeding species.

This tranquil site has a variety of habitats - open water, swamp, bog, wet woodland, scrub and gorse, all supporting their own mix of flora and fauna. Drains have been cleaned and then blocked to ensure that the site stays wet and this work, along with creation of new ponds, is encouraging a wealth of species, particularly dragonflies and damselflies such as the common darter and the emerald damselfly.

The diversity of plants and flowers provide nectar to butterflies and moths. Look out for two very interesting plants - royal fern which is recolonising, and the aromatic bog myrtle. Reed and ground nesting birds including nightjar are breeding successfully.

A short walk from the parking area passes the first pond to the living willow screen bird watching area. An offshoot of this path leads to a bird watching screen overlooking the other ponds.

We recommend wearing warm, comfortable clothing and footwear during periods of inclement weather.

With the exception of the elevated bird hide, the site is fully accessible to wheelchair users. Facilities include visitor centre with a small shop & basic refreshments; there is a disabled toilet.

Assistance dogs only.
