Cors Fochno (Borth bog) and Cors Caron are the finest examples of a raised peat bog in Britain. At just over 2,000 acres, Cors Caron fills the valley of the upper Teifi river between Tregaron and Pontrhydfendigaid. The reserve has three raised bogs - areas of deep peat that have built up over the last 12000 years, and are still growing. Cors Fochno, at the heat of the Dyfi Bioshpere, is largest expanse of primary near-natural raised bog in lowland Britain.
Rhos is a common element of place names across Ceredigion, From Rhos Llawr Cwrt in the lowlands to Ffair Rhos in the Cambrian Mountains, rhos habitats are wet grassland or pasture. Another common element in rhos and bog names is 'coch' (red), from the colour of the stems and leaves of the sedges which dominate the habitat.
Listen to the song of skylarks and meadow pipits, and find a variety of orchids in the wetter parts, as well as tall plants of angelica. Rhos environments are great for spotting butterflies, dragonflies and damselflies. Rhos Llawr Cwrt near Talgarreg has one of the biggest UK populations of the rare marsh fritillary butterfly. Other butterflies such as the pearl bordered fritillary and green hairstreak can be also be spotted.
