Tierra del Fuego (tiˈɛərə_dɛl_ˈfweɪɡoʊ, ˈtjera ðel ˈfweɣo; Spanish for "Land of Fire", rarely also Fireland in English) is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of , and a group of many islands, including Cape Horn and Diego Ramírez Islands. Tierra del Fuego is divided between Chile and Argentina, with the latter controlling the eastern half of the main island and the former the western half plus the islands south of Beagle Channel and the southernmost islands. The southernmost extent of the archipelago is just north of latitude 56°S.
The earliest known human settlement in Tierra del Fuego dates to approximately 8,000 BC. Europeans first explored the islands during Ferdinand Magellan's expedition of 1520. Tierra del Fuego and similar namings stem from sightings of the many bonfires that the natives built.
Settlement by those of European descent and the displacement of the native populations did not begin until the second half of the nineteenth century, at the height of the Patagonian sheep farming boom and of the local gold rush. Today, petroleum extraction dominates economic activity in the north of Tierra del Fuego, while tourism, manufacturing, and Antarctic logistics are important in the south.
Fuegians
The earliest human settlement occurred approximately 8,000 BC. The Yaghan were some of the earliest known humans to settle in Tierra del Fuego. Archeological sites with characteristics of their culture have been found at locations such as Navarino Island.
The name Tierra del Fuego was given by the Portuguese explorer Ferdinand Magellan while sailing for the Spanish Crown in 1520; he was the first European to visit these lands. He believed he was seeing the many fires (fuego in Spanish) of the Yaghan, which were visible from the sea, and that the "Indians" were waiting in the forests to ambush his armada.

Patagonia (pataˈɣonja) is a geographical region that encompasses the southern end of South America, governed by Argentina and Chile. The region comprises the southern section of the Andes Mountains with lakes, fjords, temperate rainforests, and glaciers in the west and deserts, tablelands and steppes to the east. Patagonia is bounded by the Pacific Ocean on the west, the Atlantic Ocean to the east, and many bodies of water that connect them, such as the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south.
The Strait of Magellan (Estrecho de Magallanes), also called the Straits of Magellan, is a navigable sea route in southern Chile separating mainland South America to the north and Tierra del Fuego to the south. The strait is considered the most important natural passage between the Atlantic and Pacific oceans. It was navigated by canoe-faring indigenous peoples including the Kawésqar for thousands of years. In 1520, the Spanish expedition of Ferdinand Magellan, after whom the strait is named, became the first Europeans to discover it.
The Selk'nam, also known as the Onawo or Ona people, are an indigenous people in the Patagonian region of southern Argentina and Chile, including the Tierra del Fuego islands. They were one of the last native groups in South America to be encountered by migrant Europeans in the late 19th century. In the mid-19th century, there were about 4000 Selk'nam; by 1919 there were 297, and by 1930 just over 100. They are considered extinct as a tribe. The exploration of gold and the introduction of farming in the region of Tierra del Fuego led to genocide of the Selk'nam.
Tree growth limitation at treeline has mainly been studied in terms of carbon limitation while effects and mechanisms of potential nitrogen (N) limitation are barely known, especially in the southern hemisphere. We investigated how soil abiotic properties ...
