Coordinates: Shetland ( / /), also called the Shetland Islands, is a subarctic archipelago of Scotland that lies north-east of mainland Britain. The islands lie some 80 km (50 mi) to the northeast of Orkney and 280 km (170 mi) southeast of the Faroe Islands and form part of the division between the Atlantic Ocean to the west and the North Sea to the east. The total area is 1,468 km2 (567 sq mi) and the population totalled 22,210 in 2009. Comprising the Shetland constituency of the Scottish Parliament, Shetland is also one of the 32 council areas of Scotland; the islands' administrative centre and only burgh is Lerwick.
The largest island, known simply as " Mainland", has an area of 967 km2 (373 sq mi), making it the third-largest Scottish island and the fifth-largest of the British Isles. There are an additional 15 inhabited islands. The archipelago has an oceanic climate, a complex geology, a rugged coastline and many low, rolling hills.
Humans have lived there since the Mesolithic period, and the earliest written references to the islands date back to Roman times. The early historic period was dominated by Scandinavian influences, especially Norway, and the islands did not become part of Scotland until the 15th century. When Shetland became part of the Kingdom of Great Britain in 1707, trade with northern Europe decreased. Fishing has continued to be an important aspect of the economy up to the present day. The discovery of North Sea oil in the 1970s significantly boosted Shetland incomes, employment and public sector revenues.
The local way of life reflects the joint Norse and Scottish heritage including the Up Helly Aa fire festival, and a strong musical tradition, especially the traditional fiddle style. The islands have produced a variety of writers of prose and poetry, many of whom use the local Shetlandic dialect. There are numerous areas set aside to protect the local fauna and flora, including a number of important seabird nesting sites.
In AD 43 and 77 the Roman authors Pomponius Mela and Pliny the Elder referred to the seven islands they call Haemodae and Acmodae respectively, both of which are assumed to be Shetland. Another possible early written reference to the islands is Tacitus' report in AD 98, after describing the discovery and conquest of Orkney, that the Roman fleet had seen " Thule, too". In early Irish literature, Shetland is referred to as Inse Catt—"the Isles of Cats", which may have been the pre-Norse inhabitants' name for the islands. The Cat tribe also occupied parts of the northern Scottish mainland and their name can be found in Caithness, and in the Gaelic name for Sutherland (Cataibh, meaning "among the Cats").
The oldest version of the modern name Shetland is Hetlandensis, the Latinised genitive form of the Old Norse name recorded in a letter from Harald count of Shetland in 1190, becoming Hetland in 1431 after various intermediate transformations. It is possible that the Pictish "cat" sound forms part of this Norse name. It then became Hjaltland in the 16th century.
As Norn was gradually replaced by Scots, Hjaltland became Ȝetland. The initial letter is the Middle Scots letter, " yogh", the pronunciation of which is almost identical to the original Norn sound, "/hj/". When the use of the letter yogh was discontinued, it was often replaced by the similar-looking letter z, hence Zetland, the misspelt form used to describe the pre-1975 county council.
Most of the individual islands have Norse names, although the derivations of some are obscure and may represent pre-Norse, possibly Pictish or even pre-Celtic names or elements.
Geography and geology
Shetland is around 170 kilometres (110 mi) north of mainland Scotland, covers an area of 1,468 square kilometres (567 sq mi) and has a coastline 2,702 kilometres (1,679 mi) long. Lerwick, the capital and largest settlement, has a population of around 7,500 and about half of the archipelago's total population of 22,000 people live within 16 kilometres (10 mi) of the town. Scalloway on the west coast, which was the capital until 1708, has a population of less than 1,000.
Only 16 of about 100 islands are inhabited. The main island of the group is known as Mainland and of the next largest, Yell, Unst, Fetlar lie to the north and Bressay and Whalsay lie to the east. East and West Burra, Muckle Roe, Papa Stour, Trondra and Vaila are smaller islands to the west of Mainland. The other inhabited islands are Foula 28 kilometres (17 mi) west of Walls, Fair Isle 38 kilometres (24 mi) south-west of Sumburgh Head, and the Out Skerries to the east.
The uninhabited islands include Mousa, known for the Broch of Mousa, the finest preserved example in Scotland of these Iron Age round towers, St Ninian's Isle connected to Mainland by the largest active tombolo in the UK, and Out Stack, the northernmost point of the British Isles. Shetland's location means that it provides a number of such records: Muness is the most northerly castle in the United Kingdom and Skaw the most northerly settlement.
The geology of Shetland is complex, with numerous faults and fold axes. These islands are the northern outpost of the Caledonian orogeny and there are outcrops of Lewisian, Dalriadan and Moine metamorphic rocks with similar histories to their equivalents on the Scottish mainland. Similarly, there are also Old Red Sandstone deposits and granite intrusions. The most distinctive feature is the ultrabasic ophiolite, peridotite and gabbro on Unst and Fetlar, which are remnants of the Iapetus Ocean floor. Much of Shetland's economy depends on the oil-bearing sediments in the surrounding seas. Geological evidence shows that at around 6100 BC a tsunami caused by the Storegga Slides hit Shetland, (as well as the rest of the east coast of Scotland), and may have created a wave of up to 25 metres (82 ft) high in the voes where modern populations are highest.
The highest point of Shetland is Ronas Hill, which only reaches 450 metres (1,480 ft) and the Pleistocene glaciations entirely covered the islands. The Stanes of Stofast is a 2,000 tonne glacial erratic that came to rest on a prominent hilltop in Lunnasting during this period.
Shetland is a National Scenic Area, although unusually this single designated area is made up of a number of discrete locations: Fair Isle, Foula, South West Mainland (including the Scalloway Islands), Muckle Roe, Esha Ness, Fethaland and Herma Ness.
Shetland has an oceanic climate, with long but mild winters and short, cool summers. The climate all year round is moderate due to the influence of the surrounding seas, with average peak temperatures of 5 °C (41 °F) in March and 14 °C (57 °F) in July and August. Temperatures over 21 °C (70 °F) are rare. The highest temperature on record was 23.4 °C (74.1 °F) in July 1991 and the coldest −8.9 °C (16.0 °F) in the Januarys of 1952 and 1959. The frost-free period may be as little as 3 months.
The general character of the climate is windy and cloudy with at least 2 mm (0.079 in) of rain falling on more than 250 days a year. Average yearly precipitation is 1,003 mm (39.5 in), with November and December the wettest months. Snowfall is usually confined to the period November to February, and snow seldom lies on the ground for more than a day. Less rain falls from April to August although no month receives less than 50 mm (2.0 in). Fog is common during summer due to the cooling effect of the sea on mild southerly airflows.
Due to the islands' latitude, on clear winter nights the "northern lights" can sometimes be seen in the sky, while in summer there is almost perpetual daylight, a state of affairs known locally as the "simmer dim". Annual bright sunshine averages 1090 hours and overcast days are common.

Due to the practice, dating to at least the early Neolithic, of building in stone on virtually treeless islands, Shetland is extremely rich in physical remains of the prehistoric eras and there are over 5,000 archaeological sites all told. A midden site at West Voe on the south coast of Mainland, dated to 4320–4030 BC, has provided the first evidence of Mesolithic human activity on Shetland. The same site provides dates for early Neolithic activity and finds at Scord of Brouster in Walls have been dated to 3400 BC. "Shetland knives" are stone tools that date from this period made from felsite from Northmavine.
Pottery shards found at the important site of Jarlshof also indicate that there was Neolithic activity there although the main settlement dates from the Bronze Age. This includes a smithy, a cluster of wheelhouses and a later broch. The site has provided evidence of habitation during various phases right up until Viking times. Heel-shaped cairns, are a style of chambered cairn unique to Shetland, with a particularly large example on Vementry.
Numerous brochs were erected during the Iron Age. In addition to Mousa there are significant ruins at Clickimin, Culswick, Old Scatness and West Burrafirth, although their origin and purpose is a matter of some controversy. The later Iron Age inhabitants of the Northern Isles were probably Pictish, although the historical record is sparse. Hunter (2000) states that in relation to King Bridei I of the Picts in the sixth century AD: "As for Shetland, Orkney, Skye and the Western Isles, their inhabitants, most of whom appear to have been Pictish in culture and speech at this time, are likely to have regarded Bridei as a fairly distant presence.” In 2011, the collective site, " The Crucible of Iron Age Shetland" including Broch of Mousa, Old Scatness and Jarlshof joined the UKs "Tentative List" of World Heritage Sites.
The expanding population of Scandinavia led to a shortage of available resources and arable land there and led to a period of Viking expansion, the Norse gradually shifting their attention from plundering to invasion. Shetland was colonised during the late 8th and 9th centuries, the fate of the existing indigenous population being uncertain. Modern Shetlanders have almost identical proportions of Scandinavian matrilineal and patrilineal ancestry, suggesting that the islands were settled by both men and women in equal measure.
Vikings then made the islands the headquarters of pirate expeditions carried out against Norway and the coasts of mainland Scotland. In response, Norwegian king Harald Hårfagre ("Harald Fair Hair") annexed the Northern Isles (comprising Orkney and Shetland) in 875. Rognvald Eysteinsson received Orkney and Shetland from Harald as an earldom as reparation for the death of his son in battle in Scotland, and then passed the earldom on to his brother Sigurd the Mighty.
The islands were Christianised in the late 10th century. King Olav Tryggvasson summoned the jarl Sigurd the Stout during a visit to Orkney and said, "I order you and all your subjects to be baptised. If you refuse, I'll have you killed on the spot and I swear I will ravage every island with fire and steel." Unsurprisingly, Sigurd agreed and the islands became Christian at a stroke. Unusually, from c. 1100 onwards the Norse jarls owed allegiance both to Norway and to the Scottish crown through their holdings as Earls of Caithness.
In 1194, when Harald Maddadsson was Earl of Orkney and Shetland, a rebellion broke out against King Sverre Sigurdsson of Norway. The Øyskjeggs ("Island Beardies") sailed for Norway but were beaten in the Battle of Florvåg near Bergen. After his victory King Sverre placed Shetland under direct Norwegian rule, a state of affairs that continued for nearly two centuries.
Increased Scottish interest
From the mid 13th century onwards Scottish monarchs increasingly sought to take control of the islands surrounding the mainland. The process was begun in earnest by Alexander II and was continued by his successor Alexander III. This strategy eventually led to an invasion by Haakon Haakonsson, King of Norway. His fleet assembled in Bressay Sound before sailing for Scotland. After the stalemate of the Battle of Largs, Haakon retreated to Orkney, where he died in December 1263, entertained on his death bed by recitations of the sagas. His death halted any further Norwegian expansion in Scotland and following this ill-fated expedition, the Hebrides and Mann were yielded to the Kingdom of Scotland as a result of the 1266 Treaty of Perth, although the Scots recognised continuing Norwegian sovereignty over Orkney and Shetland.
Pawned to Scotland
In the 14th century, Orkney and Shetland remained a Norwegian province, but Scottish influence was growing. Jon Haraldsson who was murdered in Thurso in 1231, was the last of an unbroken line of Norse jarls, and thereafter the earls were Scots noblemen of the houses of Angus and St. Clair. On the death of Haakon VI in 1380, Norway formed a political union with Denmark after which the interest of the royal house in the islands declined. In 1468, Shetland was pledged by Christian I, in his capacity as King of Norway, as security against the payment of the dowry of his daughter Margaret, betrothed to James III of Scotland. As the money was never paid, the connection with the crown of Scotland has become perpetual. In 1470, William Sinclair, 1st Earl of Caithness ceded his title to James III and the following year the Northern Isles were directly annexed to the Crown of Scotland, a process confirmed by Parliament in 1472. Nonetheless, Shetland's connection with Norway has proven to be enduring.
From the early 15th century on the Shetlanders sold their goods through the Hanseatic League of German merchantmen. The Hansa would buy shiploads of salted fish, wool and butter and import salt, cloth, beer and other goods. The late 16th century and early 17th century was dominated by the influence of the despotic Robert Stewart, Earl of Orkney, who was granted the islands by his half-sister Mary Queen of Scots, and his son Patrick. The latter commenced the building of Scalloway Castle, but after his imprisonment in 1609 the Crown annexed Orkney and Shetland again until 1643 when Charles I granted them to William Douglas, 7th Earl of Morton. These rights were held on and off by the Mortons until 1766, when they were sold by James Douglas, 14th Earl of Morton to Laurence Dundas.
Early British rule
The trade with the North German towns lasted until the 1707 Act of Union when high salt duties prohibited the German merchants from trading with Shetland. Shetland then went into an economic depression as the Scottish and local traders were not as skilled in trading with salted fish. However, some local merchant-lairds took up where the German merchants had left off, and fitted out their own ships to export fish from Shetland to the Continent. For the independent farmers of Shetland this had negative consequences, as they now had to fish for these merchant-lairds.
Smallpox afflicted the islands in the 17th and 18th centuries, but as vaccines became common after 1760 the population increased to a maximum of 31,670 in 1861. However, British rule came at price for many ordinary people as well as traders. The Shetlanders nautical skills were sought by the Royal Navy. Some 3,000 served during the Napoleonic wars from 1800 to 1815 and press gangs were rife. During this period 120 men were taken from Fetlar alone and only 20 of them returned home. By the late 19th century 90% of all Shetland was owned by just 32 people, and between 1861 and 1881 more than 8,000 Shetlanders emigrated. With the passing of the Crofters' Act in 1886 the Liberal prime minister William Gladstone emancipated crofters from the rule of the landlords. The Act enabled those who had effectively been landowners' serfs to become owner-occupiers of their own small farms. By this time fishermen from Holland, who had traditionally gathered each year off the coast of Shetland to fish for herring, triggered an industry in the islands that boomed from around 1880 until the 1920s when stocks of the fish began to dwindle.
During World War I many Shetlanders served in the Gordon Highlanders, a further 3,000 served in the Merchant Navy and more than 1500 in a special local naval reserve. The 10th Cruiser Squadron was stationed at Swarbacks Minn and during a single year from March 1917 more than 4,500 ships sailed from Lerwick as part of an escorted convey system. In total, Shetland lost more than 500 men, a higher proportion than any other part of Britain, and there were further waves of emigration in the 1920s and 1930s.
During World War II a Norwegian naval unit nicknamed the " Shetland Bus" was established by the Special Operations Executive in the autumn of 1940 with a base first at Lunna and later in Scalloway to conduct operations around the coast of Norway. About 30 fishing vessels used by Norwegian refugees were gathered and the Shetland Bus conducted covert operations, carrying intelligence agents, refugees, instructors for the resistance, and military supplies. It made over 200 trips across the sea with Leif Larsen, the most highly decorated allied naval officer of the war, making 52 of them. Several RAF bases were also established at Sullom Voe and several lighthouses suffered enemy air attacks.
Oil reserves discovered in the later 20th century in the seas both east and west of Shetland have provided a much needed alternative source of income for the islands. The East Shetland Basin is one of Europe's largest oil fields and as a result of the oil revenue and the cultural links with Norway, a small independence movement developed briefly. It saw as its model the Isle of Man, as well as Shetland's closest neighbour, the Faroe Islands, an autonomous dependency of Denmark.
Today, the main revenue producers in Shetland are agriculture, aquaculture, fishing, renewable energy, the petroleum industry (crude oil and natural gas production), the creative industries and tourism.
Fishing remains central to the islands' economy today, with the total catch being 75,767 tonnes (74,570 long tons; 83,519 short tons) in 2009, valued at over £73.2 million. In addition Mackerel, which makes up more than half of the catch in Shetland by weight and value, there are significant landings of Haddock, Cod, Herring, Whiting, Monkfish and shellfish. Farming is mostly concerned with the raising of Shetland sheep, known for their unusually fine wool. Crops raised include oats and barley; however, the cold, windswept islands make for a harsh environment for most plants. Crofting, the farming of small plots of land on a legally restricted tenancy basis, is still practiced and viewed as a key Shetland tradition as well as important source of income.
Oil and gas was first landed at Sullom Voe in 1978, and it has subsequently become one of the largest terminals in Europe. Taxes from the oil have increased public sector spending on social welfare, art, sport, environmental measures and financial development. Three quarters of the islands work force is employed in the service sector and Shetland Islands Council alone accounted for 27.9% of output in 2003. Shetland's access to oil revenues has funded the Shetland Charitable Trust which in turn funds a wide variety of local programmes. The balance of the fund in 2011 was £217million i.e., about £9,500 per head.
In January 2007, the Shetland Islands Council signed a partnership agreement with Scottish and Southern Energy for a 200-turbine wind farm and subsea cable. This renewable energy project would produce about 600 megawatts and contribute about £20 million to the Shetland economy per year. The plan is meeting significant opposition within the islands, primarily resulting from the anticipated visual impact of the development. The PURE project on Unst is a research centre which uses a combination of wind power and fuel cells to create a wind hydrogen system. The project is run by the Unst Partnership, the local community's development trust.
Knitwear is important both to the economy and culture of Shetland and the Fair Isle design is well-known. However, the industry faces challenges due to plagiarism of the word "Shetland" by manufacturers operating elsewhere and a certification trademark, "The Shetland Lady", has been registered. Shetland is served by a weekly local newspaper, The Shetland Times and the online Shetland News with radio service being provided by BBC Radio Shetland and the commercial radio station SIBC.
Shetland is a popular destination for cruise ships and in 2010 the Lonely Planet guide named Shetland as the sixth best region in the world for tourists seeking unspoilt destinations. The islands were described as “beautiful and rewarding" and the Shetlanders as "a fiercely independent and self-reliant bunch". Overall visitor expenditure was worth £16.4 million in 2006, in which year just under 26,000 cruise liner passengers arrived at Lerwick Harbour. In 2009, the most popular visitor attractions were the Shetland Museum, the RSPB reserve at Sumburgh Head, Bonhoga Gallery at Weisdale Mill and Jarlshof.
Transport between islands is primarily by ferry, and Shetland Islands Council operate various inter-island services. Shetland is also served by a domestic connection from Lerwick to Aberdeen on mainland Scotland. This service, which takes about 12 hours, is operated by NorthLink Ferries. Some services also call at Kirkwall, Orkney, which increases the journey time between Aberdeen and Lerwick by 2 hours.
Sumburgh Airport, the main airport on Shetland, is located close to Sumburgh Head, 40 km (25 mi) south of Lerwick. Loganair operates flights for FlyBe to other parts of Scotland up to ten times a day, the destinations being Kirkwall, Aberdeen, Inverness, Glasgow and Edinburgh. Lerwick/Tingwall Airport is located 11 km (6.8 mi) west of Lerwick. Operated by Directflight Ltd. in partnership with Shetland Islands Council, it is devoted to inter-island flights from the Shetland Mainland to most of the inhabited islands. Scatsta Airport near Sullom Voe allows frequent charter flights from Aberdeen to transport oilfield workers and this small terminal has the fifth largest number of international passengers in Scotland.
Public bus services are operated on Mainland, Whalsay, Burra, Unst and Yell.
The archipelago is exposed to wind and tide, and there are numerous sites of wrecked ships. Lighthouses are sited as an aid to navigation at various locations.
The Shetland Islands Council is the local authority for all the islands, based in Lerwick Town Hall. The islands' motto, which appears on the Council's coat of arms, is Með lögum skal land byggja. This phrase is taken from Njáls saga and means "By law shall the land be built up". Shetland is subdivided into 12 civil parishes that no longer have administrative significance but are sometimes used for statistical purposes, and into 18 community council areas.
In Shetland there are two High Schools— Anderson and Brae—seven Junior High Schools, and over thirty primary schools. Shetland is also home to the North Atlantic Fisheries College, the Centre for Nordic Studies and Shetland College, which are all associated with the University of the Highlands and Islands.
Shetland is represented in the House of Commons as part of the Orkney and Shetland constituency, which elects one Member of Parliament, the current incumbent being Alistair Carmichael. This seat has been held by the Liberal Democrats or their predecessors the Liberal Party since 1950, longer than any other they represent in the UK.
In the Scottish Parliament the Shetland constituency elects one Member of the Scottish Parliament (MSP) by the first past the post system. The current MSP is Tavish Scott of the Scottish Liberal Democrats. Shetland is within the Highlands and Islands electoral region.
The political composition of the Council is 22 Independents. Thus it is one of only three Councils in Scotland with a majority of elected members not representing a political party.
Roy Grönneberg, who founded the local chapter of the Scottish National Party in 1966, designed the flag of Shetland in cooperation with Bill Adams to mark the 500th anniversary of the transfer of the islands from Norway to Scotland. The colours are identical to those of the Flag of Scotland, but are shaped in the Nordic cross. After several unsuccessful attempts, including a plebiscite in 1985, the Lord Lyon King of Arms approved it as the official flag of Shetland in 2005.
Local culture, religion and the arts
After the islands were transferred to Scotland, thousands of Scots families emigrated to Shetland in the 16th and 17th centuries but studies of the genetic makeup of the islands' population indicate that Shetlanders are just under half Scandinavian in origin. This combination is reflected in many aspects of local life. For example, almost every place name in use can be traced back to the Vikings. The Norn language was a form of Old Norse, which continued to be spoken until the 18th century when it was replaced by an insular dialect of Scots known as Shetlandic, which is in turn is being replaced by Scottish English. Although Norn was spoken for hundreds of years it is now extinct and few written sources remain. Shetlandic is used both in local radio and dialect writing, and kept alive by the Shetland Folk Society.
The Lerwick Up Helly Aa is one of a variety of fire festivals held in Shetland annually in the middle of winter. The festival is just over 100 years old in its present, highly organised form. Originally a festival held to break up the long nights of winter and mark the end of Yule, the festival has become one celebrating the isles' heritage and includes a procession of men dressed as Vikings and the burning of a replica longship.
The cuisine of Shetland is based on locally produced lamb, beef and seafood, much of it organic. Inevitably, the real ale-producing Valhalla Brewery is the most northerly in Britain. Shetland competes in the biennial International Island Games, which it hosted in 2005.
Churches and religion
The Reformation reached the archipelago in 1560. This was an apparently peaceful transition and there is little evidence of religious intolerance in Shetland's recorded history. A variety of different religious denominations are represented in the islands. The Methodist Church has a relatively high membership in Shetland, which is a District of the Methodist Church (with the rest of Scotland comprising a separate District). The Church of Scotland has a Presbytery of Shetland that includes St. Columba's Church in Lerwick.
Shetland's culture and landscapes have inspired a variety of musicians, writers and film-makers. The Forty Fiddlers was formed in the 1950s to promote the traditional fiddle style, which is a vibrant part of local culture today. Notable exponents of Shetland folk music include Aly Bain and the late Tom Anderson and Peerie Willie Johnson. Thomas Fraser was a country musician who never released a commercial recording during his life, but whose work has become popular more than 20 years after his untimely death in 1978.
Walter Scott's 1822 novel The Pirate is set in "a remote part of Shetland", and was inspired by his 1814 visit to the islands. The name Jarlshof meaning "Earl's Mansion" is a coinage of his.
Hugh MacDiarmid, the Scots poet and writer lived in Whalsay from the mid-1930s through 1942, and wrote many poems there, including a number that directly address or reflect the Shetland environment such as "On A Raised Beach", which was inspired by a visit to West Linga. The 1975 novel North Star by Hammond Innes is largely set in Shetland and Raman Mundair's 2007 book of poetry A Choreographer's Cartography offers a British Asian perspective on the landscape. Vagaland, who grew up in Walls, was arguably Shetland's finest poet of the 20th century.
The Shetland Quartet by Ann Cleeves, who previously lived in Fair Isle, is a series of crime novels set around the islands.
There are two monthly magazines in production: Shetland Life and i'i' Shetland.
Michael Powell made The Edge of the World in 1937, a dramatisation based on the true story of the evacuation of the last 36 inhabitants of the remote island of St Kilda on 29 August 1930. St Kilda lies in the Atlantic Ocean, 64 kilometres (40 mi) west of the Outer Hebrides but Powell was unable to get permission to film there. Undaunted, he made the film over four months during the summer of 1936 on Foula and the film transposes these events to Shetland. Forty years later, the documentary Return To The Edge Of The World was filmed, capturing a reunion of cast and crew of the film as they revisited the island in 1978.
A number of other films have been made on or about Shetland including A Crofter's Life in Shetland (1932) A Shetland Lyric (1934), Devil's Gate (2003) and It's Nice Up North (2006), a comedy documentary by Graham Fellows.
An annual film festal takes place in the newly built Mareel, a cinema, music and education venue.
Shetland has three National Nature Reserves, at the seabird colonies of Hermaness and Noss, and at Keen of Hamar to preserve the serpentine flora. There are a further 81 SSSIs, which cover 66% or more of the land surfaces of Fair Isle, Papa Stour, Fetlar, Noss and Foula. Mainland has 45 separate sites.
The landscape in Shetland is marked by the grazing of sheep and the harsh conditions have limited the total number of plant species to about 400. Native trees such as Rowan and Crab Apple are only found in a few isolated places such as cliffs and loch islands. The flora is dominated by Arctic-alpine plants, wild flowers, moss and lichen. Spring Squill, Buck's-Horn Plantain, Scots Lovage, Roseroot and Sea Campion are abundant, especially in sheltered places. Shetland Mouse-ear ( Cerastium nigrescens) is an endemic flowering plant found only in Shetland. It was first recorded in 1837 by botanist Thomas Edmondston. Although reported from two other sites in the 19th century, it currently grows only on two serpentine hills on the island of Unst. The nationally scarce Oysterplant is found on several islands and the British Red Listed bryophyte Thamnobryum alopecurum has also been recorded.
Shetland has numerous seabird colonies. Birds found on the islands include Atlantic Puffin, Storm-petrel, Red-throated Diver, Northern Gannet and Bonxie. Numerous rarities have also been recorded including Black-browed Albatross and Snow Goose, and a single pair of Snowy Owls bred on Fetlar from 1967 to 1975. The Shetland Wren, Fair Isle Wren and Shetland Starling are subspecies endemic to Shetland. There are also populations of various moorland birds such as Curlew, Snipe and Golden Plover.
The geographical isolation and recent glacial history of Shetland have resulted in a depleted mammalian fauna and the Brown Rat and House Mouse are two of only three species of rodent present on the islands. The Shetland Field Mouse is the third and the archipelago's fourth endemic subspecies, of which there are three varieties on Yell, Foula and Fair Isle. They are variants of Apodemus sylvaticus and archaeological evidence suggests that this species was present during the Middle Iron Age (around 200 BC to AD 400). It is possible that Apodemus was introduced from Orkney where a population has existed since at the least the Bronze Age.
There are a variety of indigenous breeds, of which the diminutive Shetland Pony is probably the best known, as well as being an important part of the Shetland farming tradition. The first written record of the pony was in 1603 in the Court Books of Shetland and, for its size, it is the strongest of all the horse breeds. Others are the Shetland Sheepdog or "Sheltie", the endangered Shetland Cattle and Shetland Goose and the Shetland Sheep which is believed to have originated prior to 1000 AD. The Grice was a breed of semi-domesticated pig that became extinct in 1930. Its habit of attacking lambs cannot have aided its survival.
