Formerly in the ownership of the Trawsgoed Estate, and the Earl of Lisburne, the bog is located in the Cors Caron National Nature Reserve. In 1956, the 7th Earl of Lisburne entered into a management agreement with the Nature Conservancy Council, and the reserve lands were sold to the Countryside Council for Wales in 1986. The estate retains grazing and sporting rights over some of the reserve and adjoining farmland. On 2 September 1992, Cors Caron was put on a list of wetland sites of international importance under the Ramsar Convention. The bog is now maintained by Natural Resources Wales, successor body to the Countryside Council for Wales.
