The natural resources of Wales have contributed substantially to the economic wealth of the United Kingdom from pre-Roman times to the present. Wales has a complex and varied geology with a wealth of natural minerals. Although Wales has been strongly associated with the coal industry, it has also been the world's leading supplier of slate and of copper at different times. The country lies along the western side of Great Britain and is buffeted by the prevailing South-Westerly trade winds which bring year round rain and wind but also maintain an equable temperate climate. The combination of climate and physical geography and geology have given rise to many different types of landscape and biomes rich in species variety.

With its mountainous terrain and ample rainfall, water is one of Wales' most abundant resources. The country has many man-made reservoirs and exports water to England as well as generating power through hydroelectric schemes. The largest group of reservoirs, are in the Elan Valley and include Claerwen. Other notable bodies of water include Bala Lake, Llyn Trawsfynydd, Lake Vyrnwy, Talybont Reservoir and Llyn Brianne. Some of these are popular resorts for outdoor activities such as sailing, kayaking, cycling, fishing and bird-watching. [2]

The source of many significant rivers are located in the Welsh mountains including the River Dee, River Teifi, Afon Tywi, River Wye, and River Severn all of which have significant fisheries especially of Salmon and Sea trout.

Renewable energy

Wind is another resource that Wales has in abundance. The Gwynt y Môr is one of several offshore wind farms off the coast of North Wales and Anglesey, and is the second largest such wind farm in the world. [3] Other wind farms are found on inland, mostly upland sites, but there are none in the Snowdonia and Brecon Beacons national parks. [4]

Coal

The South Wales Coalfield extends from parts of Pembrokeshire and Carmarthenshire in the west, to Blaenau Gwent and Torfaen in the east, [5] and the rather smaller North Wales Coalfield underlies parts of Flintshire and Denbighshire. [6] Vast quantities of coal were mined in Wales during the Industrial Revolution and the earlier part of the twentieth century, after which coal stocks dwindled and the remaining pits became uneconomical as foreign coal became available at low prices. The last deep pit in Wales closed in 2008. [7]

Metal ores

Ironstone outcrops along the northern edge of the South Wales Coalfield were extensively worked for the production of iron and were important in the initiation of the Industrial Revolution in South Wales. [8]

Lead, silver and to a lesser extent zinc were mined in the upland areas of the rivers Ystwyth and Rheidol and in the headwaters of the River Severn for centuries and smaller deposits were also mined at Pentre Halkyn in Flintshire during the Roman occupation of Britain. There were also ore-bearing sites in Clwyd where lead, silver and sometimes zinc were mined. [9] Manganese, titanium and numerous other minerals occur in various parts of Wales. Gold is found in southern Snowdonia and at Dolaucothi.

Copper was a major export from Parys Mountain on Anglesey which was, at its height, the largest copper mine in the world. Copper had been known about and mined since at least the Bronze Age with a sophisticated Bronze Age copper mine on the Great Orme near Llandudno. [10] Smaller copper deposits were worked in Snowdonia which had a flourishing copper industry from the early 1800s. Although exploited in the past, none of these minerals is mined on a commercial scale today. [11]

Stone

Stone is quarried in various parts of Wales, and slate quarrying and mining has been a major industry in North Wales. The Cilgwyn Quarry was being worked in the 12th century, but later Blaenau Ffestiniog became the centre of production. [12] The Penrhyn Quarry is still producing slates, though at a reduced capacity compared to its heyday, and the Llechwedd Slate Caverns have been converted into a visitor attraction. [13] Several of the railways that used to carry the slates to the ports have been restored as tourist attractions, including the Ffestiniog Railway and the Talyllyn Railway. [14]

Oil and gas

Wales has some potential for the onshore production of oil and gas. Shale gas may be obtained by fracking and there is methane in unmined coal seams that may be extractable. Another potential source of gas is the underground controlled combustion of coal seams to produce syngas, a mixture of hydrogen, methane and carbon monoxide. [15]

Partly because of its relatively sparse population in Mid and North Wales, its unusually equable climate and its complex geology, Wales sustains a great variety of notable landscape forms, unusual biomes and areas enjoying special protection because of their natural environmental value. It is home to a number of National Nature Reserves (NNRs), sites of special scientific interest (SSSIs), five areas of outstanding natural beauty (AONBs) and three national parks

Wales has many protected areas including three national parks: Snowdonia, Brecon Beacons and Pembrokeshire Coast. It has five Areas of Outstanding Natural Beauty; Anglesey, the Clwydian Range and Dee Valley, the Gower Peninsula, the Llŷn Peninsula, and the Wye Valley. [16]

The Gower Peninsula was the first area in the United Kingdom to be designated as an Area of Outstanding Natural Beauty, in 1956.

Sea and coast

Because of its location facing into a very energetic ocean, Wales has numerous sandy beaches, a coastline rich in sea-cliffs and a relatively high tidal range in many areas. As of 2020, the coastline of Wales has 40 Blue Flag beaches, three Blue Flag marinas and one Blue Flag boat operator. [17] A significant tourism industry has developed to advantage of these coastal resources including substantial caravan parks along the north-east coast at Rhyl, Prestatyn and Kimnel Bay in parts of Pembrokeshire and along the south coast at Porthcawl and Barry

A number of westerly and south-westerly facing beaches have well developed sand-dune system behind them including Kenfig dunes, Merthyr Mawr, Morfa Harlech and Newborough Warren all of which are highly valued for their wild-life diversity including the presence of some rare plant and animal species such as the Fen orchid.

<span class="mw-page-title-main">Slate industry in Wales</span> World Heritage site in the United Kingdom

The existence of a slate industry in Wales is attested since the Roman period, when slate was used to roof the fort at Segontium, now Caernarfon. The slate industry grew slowly until the early 18th century, then rapidly during the Industrial Revolution in Wales until the late 19th century, at which time the most important slate producing areas were in northwest Wales. These sites included the Penrhyn Quarry near Bethesda, the Dinorwic Quarry near Llanberis, the Nantlle Valley quarries, and Blaenau Ffestiniog, where the slate was mined rather than quarried. Penrhyn and Dinorwig were the two largest slate quarries in the world, and the Oakeley mine at Blaenau Ffestiniog was the largest slate mine in the world. Slate is mainly used for roofing, but is also produced as thicker slab for a variety of uses including flooring, worktops and headstones.

<span class="mw-page-title-main">Geology of Wales</span> Overview of the geology of Wales

The geology of Wales is complex and varied; its study has been of considerable historical significance in the development of geology as a science. All geological periods from the Cryogenian to the Jurassic are represented at outcrop, whilst younger sedimentary rocks occur beneath the seas immediately off the Welsh coast. The effects of two mountain-building episodes have left their mark in the faulting and folding of much of the Palaeozoic rock sequence. Superficial deposits and landforms created during the present Quaternary period by water and ice are also plentiful and contribute to a remarkably diverse landscape of mountains, hills and coastal plains.

<span class="mw-page-title-main">Coal industry in Wales</span>

The coal industry in Wales played an important role in the Industrial Revolution in Wales. Coal mining in Wales expanded in the 18th century to provide fuel for the blast furnaces of the iron and copper industries that were expanding in southern Wales. The industry had reached large proportions by the end of that century, and then further expanded to supply steam-coal for the steam vessels that were beginning to trade around the world. The Cardiff Coal Exchange set the world price for steam-coal and Cardiff became a major coal-exporting port. The South Wales Coalfield was at its peak in 1913 and was one of the largest coalfields in the world. It remained the largest coalfield in Britain until 1925. The supply of coal dwindled, and pits closed in spite of a UK-wide strike against closures. Aberpergwm Colliery is the last deep mine in Wales.

The bedrock geology of Carmarthenshire in west Wales consists largely of Palaeozoic age sedimentary rocks. Unconsolidated deposits of Quaternary age in Carmarthenshire include a dissected cover of glacial till, valley floor alluvium and some scattered peat deposits in both upland and lowland settings. There are extensive beach and tidal flat deposits along the Carmarthenshire coast. The exploitation of the county's mineral riches, particularly coal and limestone, was a key part of the local economy through much of the nineteenth and twentieth centuries.

<span class="mw-page-title-main">Coastline of Wales</span> Sea-bounded areas of Wales

The coastline of Wales extends from the English border at Chepstow westwards to Pembrokeshire then north to Anglesey and back eastwards to the English border once again near Flint. Its character is determined by multiple factors, including the local geology and geological processes active during and subsequent to the last ice age, its relative exposure to or shelter from waves, tidal variation and the history of human settlement and development which varies considerably from one place to another. The majority of the coast east of Cardiff in the south, and of Llandudno in the north, is flat whilst that to the west is more typically backed by cliffs. The cliffs are a mix of sandstones, shales and limestones, the erosion of which provides material for beach deposits. Of the twenty-two principal areas which deliver local government in Wales, sixteen have a coastline, though that of Powys consists only of a short section of tidal river some distance from the open sea. Its length has been estimated at 1,680 miles (2,700 km).

<span class="mw-page-title-main">Regions of Wales</span> Undefined class of subdivision in Wales

Wales has traditionally been divided into a number of ambiguous and undefined areas described as "regions", reflecting historical, geographical, administrative, cultural and electoral boundaries within the country. Presently, the most common form of division of Wales into "regions" has been using cardinal and intercardinal references, north or south-west for example. None of the variously described "regions" have official status or defined boundaries, there is neither a fixed number of regions. Various organisations use different regions and combinations of regions for their individual purposes. This includes devolved institutions, such as Visit Wales, Natural Resources Wales, and the Welsh Government itself, using different sets of Wales' regions. Wales is most commonly sub-divided into between two and four regions, with a North–South divide, and North, Mid, South East and South West division being common. This article will list the various terms applied to be the "regions of Wales" and the regions used by various organisations.

<span class="mw-page-title-main">Manufacturing in Wales</span> Overview of the manufacturing industry of Wales

The manufacturing sector in Wales was historically centred on the mining industry, with slate, coal, tinplate and steel being important industries. Today, while traditional industries remain in smaller quantities, manufacturing in Wales is increasingly specialised and diverse, including parts of the automotive, aerospace, medical and technological industries.
