About the reserve

A valley mire once common in the uplands of North Wales. Blaen-Y-Weirglodd is a wild and remote site protected for its peat bog habitat once common in the upland valleys of North Wales. It is a Site of Special Scientific Interest with a rich variety of bog plants such as sphagnum mosses, round-leaved sundew, bog asphodel, marsh violet, marsh pennywort and bog bean. Snipe are common winter visitors to the reserve and, between late April to July, listen out for grasshopper warbler. Brown hare and stoat are frequently seen at the site and in surrounding fields.
