Peat bogs and 'rhos'

​Peat is a precious resource that can take thousands of years to form and peat bogs are an important habitats for a whole range of species, and the finest examples of raised peat bogs in lowland Britain are in Ceredigion.

Rhos and blanket bogs of the Cambrian Mountains

The three raised bogs of the Cors Caron National Nature Reserve, at just over 2,000 acres, fill the valley of the upper Teifi river between Tregaron and Pontrhydfendigaid. One of the finest examples of raised peat bogs in lowland Britain, Cors Caron is recognised internationally as an important wetland reserve. 

Cors Caron is also known as Cors Goch Glanteifi - the red bog of the Teifi riverside - for the distinctive red hue of its vegetation - sedges, carpets of sphagnum moss, dotted with the delicate, yellow flowered bog asphodel, flag iris and insect consuming sundew. This is the habitat of Ceredigion's 'county flower' too - the pretty heather like, bog rosemary (andromeda polifolia). These and other plant materials form the basis of the deep reserves of peat that have built up over the last 2,000 years, forming gentle dome shaped forms, which are still growing behind a glacial moraine, which the river Teifi has breached.

 

Ceredigion's other internationally recognised peat bog, Cors Fochno, lies near the coast between Borth and Ynyslas, at the heat of the Dyfi Bioshpere. Cors Fochno is largest expanse of primary near-natural raised bog in lowland Britain, and forms part of the Dyfi Ynyslas National Nature Reserve. Join one of the regular visits onto the bog with reserve wardens to learn about its plants, mammals and rare amphibians as well as archaeology and modern water mangement. ​​​​​​​​​​
