An Icelandic horse.
Few plants and animals have migrated to the island or evolved locally since the last ice age, 10,000 years ago. There are around 1,300 known species of insects in Iceland, which is a rather low number compared with other countries (over one million species have been described worldwide). The only native land mammal when humans arrived was the Arctic Fox, which came to the island at the end of the ice age, walking over the frozen sea. There are no native reptiles or amphibians on the island.
Phytogeographically, Iceland belongs to the Arctic province of the Circumboreal Region within the Boreal Kingdom. According to the WWF, the territory of Iceland belongs to the ecoregion of Iceland boreal birch forests and alpine tundra. Approximately three-quarters of the island are barren of vegetation; plant life consists mainly of grassland which is regularly grazed by livestock. The only tree native to Iceland is the Northern Birch Betula pubescens, which formerly formed forest over much of southern Iceland. Permanent human settlement greatly disturbed the isolated ecosystem of thin, volcanic soils and limited species diversity. The forests were heavily exploited over the centuries for firewood and timber. Deforestation caused a loss of critical topsoil due to erosion, greatly reducing the ability of birches to grow back. Today, only a few small birch stands exist in isolated reserves. The planting of new forests has increased the number of trees, but does not compare to the original forests. Some of the planted forests include new foreign species.
The animals of Iceland include the Icelandic sheep, cattle, chicken, goat and the sturdy Icelandic horse. Many varieties of fish live in the ocean waters surrounding Iceland, and the fishing industry is a main contributor to Iceland's economy, accounting for more than half of its total exports. Wild mammals include the Arctic Fox, mink, mice, rats, rabbits and reindeer. Polar bears occasionally visit the island, travelling on icebergs from Greenland. In May 2008 two polar bears came only two weeks apart. Birds, especially seabirds, are a very important part of Iceland's animal life. Puffins, skuas, and kittiwakes nest on its sea cliffs. Though Iceland no longer has a commercial whaling fleet (as of August, 2007) it still allows scientific whale hunts which are not supported by the Scientific Committee of the International Whaling Commission (IWC).
