This reserve, once the site of extensive coal mining, is a great example of how nature has reclaimed the landscape. It is a rich mix of wildlflower meadow, rhos pasture and young woodland. It is one of the best sites in Wales for the rare marsh fritillary butterfly.
Trewalkin Meadow is a small, damp, flower-rich meadow at the foot of the Black Mountains between Llangorse and Talgarth. It is how much of Brecknock would have looked 60 years ago, before the habitat was lost due to changes in farming.
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.
Cwm Wanderers once played football on this site. It is now a nature reserve of wet tussocky grassland known as Rhos pasture. It is home to the rare marsh fritillary butterfly.
The Pen y Waun nature reserve consists of two small fields situated on the edge of Waun-y-Mynach common. The fields were former garden plots for nearby cottages.
This wildflower meadow has always been managed traditionally with grazing by cattle or ponies from spring to autumn. This kind of rough, damp grassland is known in Wales as Rhos pasture and is becoming rare. Please keep dogs on a lead as skylarks often nest within the rough grass.
