Wern Plemys Nature Reserve

The reserve consists of three wildflower meadows and a large area of woodland. The reserve lies on the site of a former coal-mine and is a wonderful example of how nature can reclaim an area.

What to look out for:

Just below the main meadow are the crumbling walls of an old farmhouse. The farmer would have used the meadow for grazing his animals. The Trust continues this traditional form of management by grazing the meadows with Exmoor ponies.


Look out for ragged robin in the damper areas
Excellent views of the meadows, woodland and Ystradgynlais can be seen from the disused railway line running along the eastern boundary of the reserve. The line can be accessed from the upper right-hand corner of the main meadow.
The meadows feature a range of uncommon plants such as ragged robin, great burnet and devil's bit scabious. The damper parts provide excellent habitat for frogs.
The woodland contains trees such as oak, ash, hawthorn and alder and provides home to a range of woodland birds. If you are lucky, you may see a green woodpecker with its green and yellow colouring, red head and undulating flight.
