Tierra del Fuego National Park is a national park on the Argentine part of the island of Tierra del Fuego, within Tierra del Fuego Province in the ecoregion of Patagonic Forest and Altos Andes, a part of the subantarctic forest. Established on October 15, 1960 under the Law 15.554 and expanded in 1966, it was the first shoreline national park to be established in Argentina. The park has dramatic scenery, with waterfalls, forests, mountains and glaciers. Its 630 km2 (240 sq mi) include parts of the Fagnano and Roca lakes. The Senda Costera (Coastal Path), connecting Ensenada Bay to Lapataia Bay on Lago Roca, is a popular hiking trail within the park. Forests of Antarctic beech, lenga beech and coihue in the lower elevations of the park are home to many animal species. There are 20 species of terrestrial mammals, including the guanaco, Andean Fox, North American Beaver, European Rabbit and muskrat. Among the 90 species of birds are the Kelp Goose, Torrent Duck, Austral Parakeet, Andean Condor, Blackish Oystercatcher, and Magellanic Oystercatcher. The southernmost national park in the world, it is listed as an IUCN category II park. The park stretches 60 km (37 mi) north from the Beagle Channel along the Chilean border. Ushuaia, the capital of Tierra del Fuego Province, is 11 km (6.8 mi) from the park. The park can be reached by car or by train. The southern terminus of the Pan-American Highway is located within the park, as is the El Parque station of the End of the World Train. The first Europeans who came to explore the southern tip of South America saw the campfires of the native inhabitants of the area (the Yaghan people, also called Yámana). The Spanish explorers hence named the area "Tierra del Fuego", meaning "land of fire". Tierra del Fuego National Park is studded with mountains, lakes and rivers, which form deep valleys. It is bounded on the west by the Chilean border, on the north by Lago Fagnano, and on the south by the Beagle Channel, which forms the shoreline. It encompasses an area of 63,000 hectares (160,000 acres) and represents two ecoregions: the Altos Andes and the Patagonian Forest. While the former ecoregion is made up of hill ranges and slopes, the latter has high and jagged mountains, glacier valleys and semi-deciduous forests. The landscape of the park is the result of glacial erosion, which has created bays and beaches against a backdrop of rugged mountains and valleys. The park experiences a temperate climate with frequent rain, fog and strong winds. Westerly winds over the sea maintain a uniform climate in the park. The average annual rainfall is 700 mm (28 in). Peak rainfall (snowfall at higher elevations) occurs from March through May; there is no dry season. Average temperatures are about 0 °C (32 °F) in winter and 10 °C (50 °F) in the summer. At Ushuaia, the recorded mean annual temperature reported is 5.4 °C (41.7 °F) with maximum monthly mean of 14.2 °C (57.6 °F) and minimum of −2.4 °C (27.7 °F). The park forms the southern portion of the subantarctic forest and is known for its biological richness. The subantarctic forest vegetation is dominated by tree species of Coihue, Nires and Lenga (a tree or shrub native to the Andes and also known as Lenga Beech) apart from a profusion of massbed.[9] The flora that characterizes the "Andino-Patagonico" forests, the lenga, is well distributed over the mountain slopes above sea level to a height of 600 m (2,000 ft). Above 600 m (2,000 ft) elevation, the flora consists of altoandina with small little bushes, plants en cojin and grasses. IUCN has reported forests of southern beech species of Nothofagus pumilio, N. antarctica and N. betuloides. Other species include Berberis buxifolia, Embothrium coccineum, winter's bark Drimys winteri, and Crowberry, Empetrum rubrum and mosses. Magellan coihue (coihue de Magallanes) is found in the wettest parts of the Beagle channel coast of the park. Lenga is found in the Pipo River Valley and some parts of southern mountain slopes and may be thickly set and reach great heights. Chinese lantern, hemiparasite and Pande Indian or Llao Llao, which are fungus parasites, are found over the branches of the trees. Cinnamon is also reported in many small forest areas of the park. Peat bogs extensively found in the park. These are made up of sphagnum moss and aquatic grasses in damp valleys where low temperatures and slow moving acidic waters prevent decomposition. The flower varieties found are calafate, chaura and michay, which are orange coloured. Flag Tree, Strawberry Devil and little ferns, yellow orchids and luzuriagas are seen in the understory of forest cover. Black bush, caulking, grill and Embothrium cocci with red tubular flowers are typically seen in the Beagle Channel coast and the western part of Lapataia Bay. Also found is the chocolate scented Nassauvia.
