in the centre, and the confusingly named Black Mountains in the east, where the highest point is Waun Fach 811 metres (2,661 feet). It is formed from sedimentary rocks from the mid Ordovician through to the late Carboniferous though it is the Devonian Old Red Sandstone which is the rock most identified with the park, since it forms the larger part of the different mountain massifs including South Wales' highest point Pen y Fan at 886m. Like many other upland national parks it is glacial activity during the Quaternary ice ages which is responsible for many of the well-known landforms. The west of the park is also designated as Fforest Fawr Geopark in recognition of its geological interest, and includes Waterfall Country. A number of former tramroads and the Monmouthshire and Brecon Canal running down the Usk valley dating from the Industrial Revolution now serve as recreational facilities. The Brecon Beacons National Park Authority is a special purpose local authority with wide-ranging responsibilities for the conservation and enhancement of the landscape and the promotion of its enjoyment by the public, and in particular exercises planning functions across the designated area of the park. List of national parks In the 1990s, an independent panel chaired by Professor Ron Edwards from Cardiff University reviewed the operation of the Parks over a period of 40 years, which culminated in a report known as "the Edwards Report" and subsequent establishment of "free-standing, independent authorities" through the Environment Act 1995 and set up in 1996. In 2004, the Welsh Government published an independent review of the National Parks and 3 years later produced a policy statement on National Parks and NPAs. In 2014, the 'Commission on Public Service Governance and Delivery' recommended that NPAs collaborated further with each other, with local authorities, with Natural Resources Wales etc., to share expertise, avoid duplication, and to maximise the use of resources. Proposed national parks Two areas of Wales have been proposed by campaigners to become national parks: Clwydian Range and Dee Valley AONB has been proposed to become a national park since 2010, with Welsh Labour supporting a new national park in north-east Wales in their manifesto for the 2021 Senedd election. Cambrian Mountains has been bidding for national park status since the 1960s, with their 1973 bid rejected by the Welsh Office. Campaigns for a Cambrian Mountains national park in Mid Wales still continue. National Parks
