Sheep brought later from southern Europe were long-tailed, white-fleeced and larger. These displaced the short-tailed sheep in most areas, and by the early nineteenth century, short-tailed sheep remained only in remoter parts of the west and north, including Scandinavia, the area around the Baltic, Ireland, Cornwall, the Highlands of Scotland, and various islands. Long-tailed sheep then spread into most of these areas too, and by the early twentieth century short-tailed sheep were restricted to very remote islands and mountains. From the mid-nineteenth century (and especially after the middle of the twentieth century), many of the surviving short-tailed breeds became recognised as worthy of preservation for curiosity, for cultural reasons, as ornamental animals, or for conservation of genetic diversity. Breeds While some have become extinct, more than thirty of these breeds survive. They include: the Åland or Ålandsfår – From Åland, an archipelago forming part of Finland; originally brought from Gotland. Horned or not in both sexes, various colours including white and grey. Very rare. the Boreray – Survivors of the sheep kept by the crofters of the St Kilda archipelago off the west coast of Scotland, now living only on the island of Boreray but formerly also kept on the larger island of Hirta. Horned in both sexes (formerly often two pairs of horns), usually creamy white with dark face and legs, but may also be dark all over. Descended from earlier short-tailed Hebridean sheep, crossed with Scottish Blackface. the Castlemilk Moorit – From the Castlemilk estate in Dumfriesshire in Scotland. Horned in both sexes, moorit (reddish brown). Bred as ornamental parkland animals from Manx Loaghtan, Shetland and wild Mouflon. the Dala Pälsfår – From Sweden, one of the Swedish Landrace group of breeds. Males mostly horned, females polled. Usually white. Very rare. the Estonian Ruhnu – From the Estonian island of Ruhnu. Some males horned, white or cream with grey head; some individuals have one or two wattles beneath the head; tail short or medium-length. the Faeroe Sheep or Føroyskur seyður – From the Faroe Islands ("Sheep Islands"). Similar to Icelandic sheep: usually horned in males, many different colours and patterns. the Finnsheep – From Finland. Horned in males only, usually white in North America, other colours in Finland. Multiple births frequent (up to seven or even nine live lambs). the Gestrike Sheep or Gestrikefår the Gotland – From the island of Gotland, a Swedish island in the Baltic.
