National parks of the United Kingdom

• Peak District: The central location of this park provides for the coincidence of the northern limit of many lowland species, such as the stemless thistle and nuthatch and the southern extent of many northern upland species, such as the mountain hare and globe flower. The Carboniferous Limestone of the White Peak in its southern and central areas, gives rise to peaks formed by harder reef limestone and dales rich in wildlife (typically over fifty species of wildflower and herb per square metre) gouged out by meltwater from the Ice Age. In the north, east and west is the Dark Peak where the rocks are shale, sandstone and gritstone and where layers of peat have given rise to bleak moorland landscapes.[9]
• Lake District: England's largest national park has geology providing a dramatic record of nearly 500 million years, with evidence of colliding continents, deep oceans, tropical seas, and kilometre-thick ice sheets. The area has the largest and deepest lakes and highest peaks in England. This landscape is overlaid by thousands of years of human activity and the habitats for wildlife to be found in the park include mires, limestone pavement, upland heath, screes and arctic-alpine communities, lakeshore wetlands, estuary, coastal heath and dunes.[10]
• Dartmoor: Dartmoor is the largest and wildest area of open country in the south of England. Granite, intruded 295 million years ago underlies 65% of the park and is surrounded by sedimentary rocks including limestones, shales and sandstones belonging to the Carboniferous and Devonian periods. Almost half of the park is moorland, and within it are four separate national nature reserves, including the 366 hectare East Dartmoor Woods & Heath. There are also over forty locations designated as Sites of Special Scientific Interest within the national park covering 26,169 hectares. Dartmoor is also home to England's second highest waterfall (Canonteign Falls) and highest man made waterfall.[11]
• North York Moors: Boasting archaeology dating from the end of the last Ice Age, the park contains the largest Iron Age hill-fort in the North of England, Roman forts, castles and abbeys, moorland crosses and important early industrial sites.[12] Its ancient and varied geology includes the evidence left behind of ancient oceans, huge river deltas and great ice sheets. The evidence left behind by these events has brought geologists to the area for over a century, including figures such as William Smith, 'the father of English geology'. The area is also famous for its fossils, from ammonites to dinosaur footprints.[13]
• Yorkshire Dales: The park straddles the central Pennines, known as the backbone of England. At the Millstone Grit-capped Three Peaks it rises to over 2,300 ft, contrasting with its deep cut valleys (dales) from which it derives its name. In the south the park boasts limestone (Karst) scenery, with its crags, pavements and extensive cave systems, whilst in the north valleys with distinctive stepped profiles are separated by extensive moorland plateaux. A different geology shapes the grassy rounded hills with deep ravines in the west known as the Howgill Fells. The park is noted for its glacial and post-glacial landforms including the drumlin fields, Norber erratics, and the moraines and post-glacial lakes of Semerwater and Malham Tarn. The park also boasts waterfalls including Hardraw Force and the Aysgarth Falls.[14][15]
• Exmoor: The majority of Exmoor's rocks were formed during the Devonian period of geological history between about 410 and 360 million years ago,[16] the most prominent being old and new red sandstones, Devonian slates, shales and limestone. The park rises to 519m at Dunkery Beacon and boasts 55 km of coastline towards which flow a number of rivers, most notably the River Lyn. In contrast the Exe flows south and east. A number of settlements are found within the park including the much visited Lynton and Lynmouth.[17]
• Northumberland: With a population of around 2,000 people this is the least populated of all the national parks in England and Wales. Rising to 815m at The Cheviot, the park contains over 1,100 km of paths for walking, cycling and horse-riding. The park also contains a Ramsar site (an international site for the protection of wetlands) as well as 31 Sites of Special Scientific Interest, six Special Areas of Conservation and three national nature reserves. The park's human heritage is no less impressive than its natural diversity, with 259 listed buildings, 432 scheduled ancient monuments and 3,883 Historic Environment Records.[18]
• The Broads: Britain's largest nationally protected wetland, the Norfolk and Suffolk Broads is considered to be the eleventh member of the national park family, but in fact was designated through its own Act of Parliament in 1988 gaining similar status to a national park.[19] The Broads was not established as a national park, but was described at the time as having a 'status equivalent to that of a national park'. It has since adopted the title 'national park' and is a member of the UK national parks family, with the same level of landscape protection and an additional statutory purpose; to protect the interests of navigation.[20] Its rivers, broads (shallow lakes), marshes and fens make this area rich in rare habitats, supporting myriad plants and animals. It is also one of Europe's most popular inland waterways. There are six rivers (Bure, Ant, Thurne, Yare, Chet and Waveney) and 63 broads within the park, comprising over 125 miles (200 km) of navigable waterways. The How Hill National Nature Reserve is wholly contained within the boundaries of the park, as well as 28 Sites of Special Scientific Interest, most of which fall under the Ramsar Convention on Wetlands of International Importance.[21]
• New Forest: England's smallest national park[22] was designated as a hunting ground by William the Conqueror almost 1,000 years before it became a national park and has its own section in the Domesday Book, in 1086. Originally the term 'forest' referred to the designation as a hunting ground subject to forest law, not to a collection of trees[22] and today less than half the national park is tree-covered (22,300 hectares).[23] The rest is heather- and bracken-covered heath, open pasture, marsh, villages and coastline, and the park contains the largest remaining lowland heath in Europe as well as three quarters of Europe's 120 lowland valley mires.[24] 38,000 hectares of the park is covered by the historic 'Perambulation' in which commoners’ rights apply and their animals can roam freely.[22] Amongst the 700 species of wildflower in the forest grow the blue marsh gentian and the bog orchid and the park is the only place in Britain where the wild gladiolus grows. The park is home to five types of deer, all species of British newt, all three native species of British snake, the UK’s largest breeding population of the Dartford warbler, the rare Southern Damselfly with thirty colonies, thirteen native species of British bat and the New Forest cicada, rediscovered in 1962.[25] The park also contains a wealth of human history with 214 scheduled ancient monuments.[26]
• South Downs: The most recently designated national park in the United Kingdom is a line of hills that run from Winchester in the west to Eastbourne in the east. The underlying geology of the eastern half, from the River Arun to Eastbourne, is mainly hills made of Chalk. To the west of the Arun, the area is wider and includes not only chalk hills but also part of the Weald made of sandstones and clay.[27] Most of the rocks that make up the South Downs were formed 120 million years ago, uplifted by earth movements and pushed up into a huge dome about 125 miles long and 50 miles wide which was then worn away to form the North Downs, South Downs and the plain of the Weald.[28] Amongst the key habitats overlaying this geology are chalk grassland, lowland heath and floodplain grazing marsh. The park rises to 280 metres at Blackdown in Sussex.[29] The park has the highest population of any national park in the UK which at 107,929 is bigger than the next two largest combined (Lake District: 42,000 and Peak District: 38,000). The park has a wealth of cultural heritage from evidence in Boxgrove of the earliest humans, through to contemporary arts, such as Edward James’ collection of surrealist art at West Dean College.[30] The park contains 600 Scheduled Monuments, over 5,000 listed buildings, two registered battlefields and 165 conservation areas.[29]

• Snowdonia: The largest national park in Wales, includes the highest mountain in England and Wales, and Wales' largest natural lake. The area is steeped in culture and local history, where more than half its population speak Welsh[31] Fossil shell fragments on the summit of Snowdon date from over 500 million years ago and the ancient ‘Harlech Dome’ of which Snowdon and Cadair Idris form the northern and southern extents respectively, was created in the Cambrian Period before the volcanoes erupted. The more recent Ice Age glaciers were at their peak 18,000 years ago in Snowdonia and formed the distinctive U-shaped valleys including Llanberis and Nant Gwynant in the north and Tal-y-llyn Lake in the south.[5]
• Pembrokeshire Coast: The only UK national park recognised primarily for its coastline, it covers almost all the Pembrokeshire Coast, every offshore island, the Daugleddau estuary and large areas of the Preseli Hills and the Gwaun Valley. It is an ecologically rich area recognised as of international importance for a wide range of high quality habitats and rare species. The park contains thirteen Special Areas of Conservation, five Special Protection Areas, one of three UK marine nature reserves and seven national nature reserves as well as sixty Sites of Special Scientific Interest.[32] The park also contains a wealth of human history and culture, including the UK's smallest city, St Davids and Iron Age forts. Within the park there are also a total of sixty geological conservation sites ranging from small roadside quarries and isolated crags on hilltops to many kilometres of coastline.[33]
• Brecon Beacons: The last of the original ten national parks to have been designated in the 1950's, the park straddles the divide between rural mid Wales and industrial South Wales. 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 in the UK, 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.[34]

• Loch Lomond and The Trossachs: The park, the fourth largest in the British Isles, includes 21 Munros (including Ben Lomond, Ben Lui, Beinn Challuim, Ben More and two peaks called Ben Vorlich) and 20 Corbetts. There are two forest parks (Queen Elizabeth Forest Park and Argyll Forest Park), and two national nature reserves.[35]
• Cairngorms: The largest national park in the British Isles, the heart of it is the eponymous maintain range, the Cairngorms, but these mountains form only one part of it, alongside other hill ranges such as the Angus Glens and the Monadhliath, and lower areas like Strathspey and upper Deeside. Three major rivers rise in the park: the Spey, the Dee, and the Don.[36]

There are currently no national parks in Northern Ireland though there have been controversial moves to establish one in the Mourne Mountains.[37] If established, it would stretch from Carlingford Lough to Newcastle and Slieve Croob. Though it might create jobs in tourism, there were fears that it would drive up the area's cost of living.
