Straddling the English border, near Whitchurch in Shropshire and Wrexham in Wales, lies one of the biggest and best raised bogs in Britain. Its astonishingly varied wildlife makes it a place of international importance.
The reserve has 18 species of bog moss, as well as many other characteristic bog plants, such as the insect-eating round-leaved sundew, and more uncommon plants, too, like bog asphodel, bog rosemary, lesser bladderwort, white-beaked sedge, the rare mosses Dicranum bergeri and D. leioneuron and regionally rare golden bogmoss Sphagnum pulchrum.
