Ireland Totally Explained

Ireland (; Ulster Scots: Airlann) is the third largest island in Europe behind Great Britain and Iceland. It is also the twentieth largest in the world. It lies to the northwest of Continental Europe and is surrounded by hundreds of islands and islets. To the east of Ireland, separated by the Irish Sea, is the island of Great Britain. Politically, the Republic of Ireland (also known simply as Ireland) covers five sixths of the island, with Northern Ireland, part of the United Kingdom, covering the remainder in the northeast. The name 'Ireland' derives from the Irish word Éire, with the addition of the Germanic word 'land'. The derivation of Éire in turn is from Eueriio and Ériu. This word, from Proto-Celtic *Īwerjū, which also gave Middle Welsh Iwerd "Irish Sea", originally meant "fatness", in the sense of fertile.
The population of the island is slightly under six million (2006/7), with almost 4.25 million in the Republic of Ireland (1.7 million in Greater Dublin) and an estimated 1.75 million in Northern Ireland (0.6 million in Greater Belfast ). This is a significant increase from a modern historical low in the 1960's.

Political geography

The island of Ireland has two distinct jurisdictions:

Ireland (legal name Ireland, legal description the Republic of Ireland), a sovereign state, covers five sixths of the island. Its capital is Dublin.
Northern Ireland, part of the United Kingdom of Great Britain and Northern Ireland, covers the remaining sixth. Its capital is Belfast.

For the political history of the island, see History of Ireland.

Population	Area (km²)	Largest city
503,083	17,713	Galway
2,292,939	19,774	Dublin
1,172,170	24,608	Cork
1,993,918	24,481	Belfast

Traditionally, Ireland is subdivided into four provinces: Connacht, Leinster, Munster and Ulster; and, in a system developed between the 13th and 17th centuries, 32 counties. Twenty-six of the counties are in the Republic of Ireland, and the remaining six (all in Ulster) are in Northern Ireland. Notably, Ulster and Northern Ireland are neither synonymous nor coextensive, as three counties of Ulster; Cavan, Donegal and Monaghan; are part of the Republic. Counties Dublin, Cork, Limerick, Galway, Waterford and Tipperary have been broken up into smaller administrative areas, but are still considered by Ordnance Survey Ireland to be official counties. The counties in Northern Ireland are no longer used for local government, although their traditional boundaries are still used in sports and in some other cultural areas.

All-island institutions

Despite the constitutional division of the island, in a number of areas it operates officially as a single entity. In particular, with some notable exceptions, the island operates as a single country in terms of sporting, religious and commercial life. There are also all-island dimensions to governance on the island.
   For example, most of the most popular sports on the island operate on an all-Ireland basis, such as Gaelic Games, Rugby and Golf. The notable exception to this is soccer, although an all-Ireland cup competition, the Setanta Cup, was created in 2005. The creation of an all-island league and a single international team has been publicly touted by various prominent figures on the island in recent years, such as Irish government minister Dermot Ahern and Northern Ireland legend George Best. However, the international governing body, FIFA, has ruled it out as impossible under its rules, and the respective local bodies have expressed no interest.
   All major religious bodies, the Roman Catholic Church, the Methodist Church in Ireland, the Church of Ireland/Anglican and the Presbyterian Church in Ireland, are organised on an all-island basis. Some trade unions are also organised on an all-island basis and associated with the Irish Congress of Trades Unions (ICTU) in Dublin, while others in Northern Ireland are affiliated with the Trades Union Congress (TUC) in the United Kingdom, and some affiliate to both — although such unions may organise in both parts of the island as well as in Britain. The Union of Students in Ireland (U.S.I.) and the Union of Secondary Students (USS) operate in both jurisdictions, but the former organises jointly in Northern Ireland with the National Union of Students of the United Kingdom (N.U.S.), under the name NUS-USI.
   An increasingly large amount of commercial activity operates on an all-Ireland basis, particularly in the context of the European Union. There have been calls for the creation of an "all-island economy" from members of the business community and policy-makers on both sides of the border, so as to benefit from economies of scale and boost competitiveness in both jurisdictions. This is a stated aim of the Irish government and nationalist political parties in the Northern Ireland Assembly. One commercial area in which the island already operates largely as a single entity is the energy market.
   The Belfast Agreement provides for all-Ireland governance in various guises. For example, a North-South Ministerial Council was established as a forum in which ministers from the Irish government and the Northern Ireland Assembly can discuss matters of mutual concern and formulate all-Ireland policies in twelve "areas of cooperation", such as agriculture, the environment and transport. Six of these policy areas have been provided with implementation bodies, an example of which is the Food Safety Promotion Board. Tourism policy is also managed on an all-Ireland basis, by Tourism Ireland. 17 March is celebrated throughout the island of Ireland as Saint Patrick's day.

Physical geography

.]]
A ring of coastal mountains surrounds low central plains. The highest peak is Carrauntoohil in County Kerry, which is 1,038 m (3,406 ft). The River Shannon, at 386 km (240 miles) is the longest river in Ireland. The island's lush vegetation, a product of its mild climate and frequent but soft rainfall, earns it the sobriquet "Emerald Isle". The island's area is 84,412 km² (32,591 square miles).
Ireland's least arable land lies in the south-western and western counties. These areas are largely mountainous and rocky, with dramatic green vistas, hence the attributive name "the Emerald Isle".

Climate

Overall, Ireland has a mild, but changeable, Oceanic climate with few extremes. The warmest recorded air temperature was 33.3 °C (91.94 °F) at Kilkenny Castle, County Kilkenny on 26 June 1887, whereas the lowest recorded temperature was -19.1 °C (-2.38 °F) at Markree Castle, County Sligo on 16 January 1881.
   Other statistics show that the greatest recorded annual rainfall was 3964.9 mm in the Ballaghbeena Gap in 1960. The driest year on record was 1887, with only 356.6 mm of rain recorded at Glasnevin, while the longest period of absolute drought was in Limerick where there was no recorded rainfall over 38 days during April and May of 1938.
   The climate is typically insular, and as a result of the moderating moist winds which ordinarily prevail from the Atlantic, it's of a temperate nature, avoiding the extremes in temperature of many other global areas sharing similar latitudes.
   Precipitation falls throughout the year, but is light overall, particularly in the east. The west, however, tends to be wetter on average and prone to the full force of Atlantic storms, more especially in the late autumn and winter months, which occasionally bring destructive winds and high rainfall totals to these areas, as well as snow and hail. The regions of North Galway and East Mayo have the highest incidents of recorded lightning annually (5 to 10 days per year). Munster in the south records the least snow with Ulster in the north more prone to snow. Some areas along the south and southwest coasts have not had any lying snow since February 1991.
   Inland areas are warmer in summer, and colder in winter - there are usually around 40 days of below freezing temperatures (0 °C) at inland weather stations, but only 10 days at coastal stations. Ireland is sometimes affected by heat waves, most recently 1995, 2003, 2006.

Geology

Geologically the island consists of a number of provinces - in the far west around Galway and Donegal is a medium to high grade metamorphic and igneous complex of Caledonide (Scottish Highland) affinity. Across southeast Ulster and extending southwest to Longford and south to Navan is a province of Ordovician and Silurian rocks with more affinities with the Southern Uplands province of Scotland. Further south, there's an area along the Wexford coast of granite intrusives into more Ordovician and Silurian rocks with a more Welsh affinity.
   In the southwest, around Bantry Bay and the mountains of Macgillicuddy's Reeks, is an area of substantially deformed but only lightly metamorphosed Devonian-aged rocks.
   This partial ring of "hard rock" geology is covered by a blanket of Carboniferous limestones over the centre of the country, giving rise to the comparatively fertile and famously "lush" landscape of the country. The west coast district of The Burren around Lisdoonvarna has well developed karst features. Elsewhere, significant stratiform lead-zinc mineralisation is found in the limestones (around Silvermines and Tynagh).
   Hydrocarbon exploration is continuing. The first major find was the Kinsale Head gas field off Cork/Cobh by Marathon Oil in the mid-1970s. More recently, in 1999, Enterprise Oil announced the discovery of the Corrib Gas Field. This has increased activity off the west coast in parallel with the "West of Shetland" step-out development from the North Sea hydrocarbon province. Exploration continues, with a frontier well planned north of Donegal for August 2006 and continuing drilling of prospects in the Irish Sea and St Georges Channel.

Wildlife

Ireland has fewer animal and plant species than either Britain or mainland Europe because it became an island shortly after the end of the last Ice Age, about 8,000 years ago. Many different habitat types are found in Ireland, including farmland, open woodland, temperate broadleaf and mixed forests, conifer plantations, peat bogs, and various coastal habitats.

Fauna

Only 26 land mammal species are native to Ireland, because it was isolated from Europe by rising sea levels after the Ice Age. Some species, such as the red fox, hedgehog, and badger are very common, whereas others, like the Irish hare, red deer and pine marten are less so. Aquatic wild-life - such as species of turtle, shark, whale, dolphin, and others - are common off the coast. About 400 species of birds have been recorded in Ireland. Many of these are migratory, including the swallow. Most of Ireland's bird species come from Iceland, Greenland, Africa among other territories. There are no snakes in Ireland and only one reptile (the common lizard) is native to the country. Extinct species include the great Irish elk, the wolf, the great auk, and others. Some previously extinct birds - such as the golden eagle - have recently been reintroduced after decades of extirpation.
Agriculture drives current land use patterns in Ireland, leaving limited land to preserve natural habitats, in particular for larger wild mammals with greater territorial requirements. With no top predator in Ireland, populations of animals that can't be controlled by smaller predators (such as the fox) are controlled by annual culling, for example semi-wild populations of deer.

Flora

Until medieval times Ireland was heavily forested with oak, pine, beech and birch. Forests now cover about 9% (445,000 hectares or 1 million acres), of the land. Because of its temperate climate, many species, (including sub-tropical ones like the Palm Tree (Arecaceae)) will grow in Ireland. Much of the land is now covered with pasture, and there are many species of wild-flower. Gorse (Ulex europaeus), a wild furze, is commonly found growing in the uplands, and ferns are plentiful in the more moist regions, especially in the western parts of Ireland. It is home to hundreds of plant species, some of them unique to the island. The country has been invaded by: Spartina × townsendii H. & J. Groves. The country has been invaded by some algae, some of which are now well established: Asparagopsis armara Harvey first recorded by de Valera in 1939; Colpomenia peregrina now locally abundant it was first recorded in the 1930s; Sargassum muticum (Yendo) Fensholt now well established in Strangford Lough; Codium fragile ssp. atlanticum and Codium fragile ssp. tomentosum both of these subspecies are now well established.

The impact of agriculture

The long history of agricultural production coupled with modern intensive agricultural methods (such as pesticide and fertiliser use) has placed pressure on biodiversity in Ireland. "Runoff" of contaminants into streams, rivers and lakes impact the natural fresh-water ecosystems. A land of green fields for crop cultivation and cattle rearing limits the space available for the establishment of native wild species. Hedgerows however, traditionally used for maintaining and demarcating land boundaries, act as a refuge for native wild flora. Their ecosystems stretch across the countryside and act as a network of connections to preserve remnants of the ecosystem that once covered the island. Subsidies under the Common Agricultural Policy which supported these agricultural practices are undergoing reforms. The CAP still subsidises some potentially destructive agricultural practices, however, the recent reforms have gradually decoupled subsidies from production levels and introduced environmental and other requirements. Forested areas typically consist of monoculture plantations of non-native species which may result in habitats that are not suitable for supporting a broad range of native species of invertebrates. Remnants of native forest can be found scattered around the country, in particular in the Killarney National Park. Natural areas require fencing to prevent over-grazing by deer and sheep that roam over uncultivated areas. This is one of the main factors preventing the natural regeneration of forests across many regions of the country. ==
