Biodiversity in Wrexham
Wrexham County Borough possesses an extremely rich and varied array of habitats and species. From east to west there is incredible diversity resulting from differences in soils, topography, land use and legacies of the past. To the west, the open moorland of the Ruabon and Esclusham Mountains are a valuable habitat for several important bird populations including the most important site for black grouse in Wales. The River Ceiriog Valley, and surrounding Berwyn Mountains, are a patchwork of small farms, woodlands, open moorland and scrub.
In the eastern lowland areas of the borough including the River Dee and its floodplain, extensive areas of floodplain meadow support an array of breeding birds, insects and small mammals. The extremely dense occurrence of ponds in the lowlands is of European importance and essential for the protection of the great crested newt population. Fenns, Whixall and Bettisfield Moss National Nature Reserve, once formed part of a huge lowland raised bog site which developed after the last glaciation. The peat body supports dozens of locally and nationally rare species and is of European importance.
