Isla Grande de Tierra Del Fuego - Flora

Flora

Only 30% of the islands have forests, which are classified as Magellanic subpolar; the northeast is made up by steppe and cool semidesert.

There are six species of tree found in Tierra del Fuego: Canelo or Winter's Bark (Drimys winteri), Maytenus magellanica, Pilgerodendron uviferum the southernmost conifer in the world, and three kinds of Southern Beech; Nothofagus Antarctica, Nothofagus pumilio and the evergreen Nothofagus betuloides. Very delicious fruits grow in open spaces in these forests, such as beach strawberry (Fragaria chiloensis var. chiloensis forma chiloensis) and calafate (Berberis buxifolia), which were and are collected respectively by Indians and countrymen. These forests are unique in the world for having developed in a climate with such cold summers. Tree cover extends very close to the southernmost tip of South America. Winds are so strong that trees in wind-exposed areas grow twisted by the force of winds, and people call the trees "flag-trees" for the shape that they need to take in the fight with the wind. Tree vegetation extends as far south as the Isla de los Estados, Navarino Island and the north of Hoste Island. At altitudes above, dwarf nothofagus communities are found. Going further south, Wollaston Islands and the south of Hoste Island are covered by subantarctic tundra.

Forests from Tierra del Fuego have expanded beyond local importance; they have been a source of trees that have been planted abroad in places with practically the same climate but which were originally devoid of trees like Faroe Islands and nearby archipelagos. Most species were gathered from the coldest places in Tierra del Fuego, sites mainly with tundra borders. This effort resulted in positive changes, as the heavy winds and cool summers in the Faroe Islands did not allow the growth of trees from other regions in the world. The imported trees are used ornamentally, as curtains against wind, and for fighting erosion caused by storms and grazing in the Faroe Islands.
