Theme I. Inventory, stratigraphy and conservation of mires and peatlands
Cors Fochno (Borth Bog) is an almost pristine, active estuarine raised peatland on the west coast of Wales which has a high level of National and International protection There has been a long history of peripheral human intervention mainly related to peat extraction and drainage. From the 1970s many of the drainage channels were blocked and using a rocky outcrop called Llwyn y garreg as a baseline the shrinkage and subsequent recovery of the peat level has been followed suggesting that the blockage of the drains has had a positive effect on the surface level of the bog.
