Skye - Wildlife

Wildlife

The Hebrides generally lack the biodiversity of mainland Britain, but like most of the larger islands, Skye still has a wide variety of species. Observing the abundance of game birds Martin wrote:

There is plenty of land and water fowl in this isle - as hawks, eagles of two kinds (the one grey and of a larger size, the other much less and black, but more destructive to young cattle), black cock, heath-hen, plovers, pigeons, wild geese, ptarmigan, and cranes. Of this latter sort I have seen sixty on the shore in a flock together. The sea fowls are malls of all kinds - coulterneb, guillemot, sea cormorant, &c. The natives observe that the latter, if perfectly black, makes no good broth, nor is its flesh worth eating; but that a cormorant, which hath any white feathers or down, makes good broth, and the flesh of it is good food; and the broth is usually drunk by nurses to increase their milk. —Martin Martin, A Description of The Western Islands of Scotland.

Similarly, Samuel Johnson noted that:

At the tables where a stranger is received, neither plenty nor delicacy is wanting. A tract of land so thinly inhabited, must have much wild-fowl; and I scarcely remember to have seen a dinner without them. The moor-game is every where to be had. That the sea abounds with fish, needs not be told, for it supplies a great part of Europe. The Isle of Sky has stags and roebucks, but no hares. They sell very numerous droves of oxen yearly to England, and therefore cannot be supposed to want beef at home. Sheep and goats are in great numbers, and they have the common domestic fowls." —Samuel Johnson, A Journey to the Western Islands of Scotland.

In the modern era avian life includes the corncrake, red-throated diver, kittiwake, tystie, Atlantic puffin, goldeneye and golden eagle. The eggs of the last breeding pair of white-tailed sea eagle in the UK were taken by an egg collector on Skye in 1916 but the species has recently been re-introduced. The chough last bred on the island in 1900. Mountain hare (apparently absent in the 18th century) and rabbit are now abundant and preyed upon by wild cat and pine marten. The rich fresh water streams contain brown trout, Atlantic salmon and water shrew. Offshore the edible crab and edible oyster are also found, the latter especially in the Sound of Scalpay. There are nationally important horse mussel and brittlestar beds in the sea lochs and in 2012 a bed of 100 million flame shells was found during a survey of Loch Alsh.

Heather moor containing ling, bell heather, cross-leaved heath, bog myrtle and fescues is everywhere abundant. The high Black Cuillins weather too slowly to produce a soil that sustains a rich plant life, but each of the main peninsulas has an individual flora. The basalt underpinnings of Trotternish produce a diversity of Arctic and alpine plants including alpine pearlwort and mossy cyphal. The low-lying fields of Waternish contain corn marigold and corn spurry. The sea cliffs of Duirinish boast mountain avens and fir clubmoss. Minginish produces fairy flax, cats-ear and black bog rush. There is a fine example of Brachypodium-rich ash woodland at Tokavaig in Sleat incorporating silver birch, hazel, bird cherry, and hawthorn.

The local Biodiversity Action Plan recommends land management measures to control the spread of ragwort and bracken and identifies four non-native, invasive species as threatening native biodiversity: Japanese knotweed, rhododendron, New Zealand flatworm and mink. It also identifies problems of over-grazing resulting in the impoverishment of moorland and upland habitats and a loss of native woodland, caused by the large numbers of red deer and sheep.
