Factsheets and Guides for Your Visit

Cae Bryntywarch and its common cotton grass meadow

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.

Wood bitter vetch is a nationally scarce plant found here

What to look out for

The meadow is home to a range of colourful plants. In spring it is flecked with the pinks of common spotted and heath spotted orchids, which are then followed by the yellows of bog asphodel and dyer’s greenweed. In the summer, the dense lilac-blue heads of devil’s-bit scabious flowers add to the colourful display.

Standing towards the top of the meadow gives good views of the surrounding farmland. Buzzards and red kites can sometimes be seen soaring overhead and in the spring the distinctive call of the cuckoo can sometimes be heard.

Look out for bog asphodel with its yellow flowers and scimitar-like leaves
