Combination For American Lock
The Big Island is the largest in South America and is divided into two parts through the meridian of 68 ° 36'que is the one that corresponds to the international border and covers an area of \u200b\u200bapproximately 45,000 km2. The boundary continues then East, accompanying the direction of the Beagle Channel, which is defined as Chilean territory to all islands and islets in the south of the border, including islands as Hoste, Navarino, Picton, Lennox and Nueva among others.
The area north of the island is characterized as a continuation of Magellan or Patagonian steppe, where the plain is covered by vegetation, which is dominated by grasses (Festuca spp.) Dotted with patches of shrubs ( Mata Mata green and black). This is the space that alternates with "vegas" (wetter areas along watercourses), where conditions are best sheep and cattle to graze, so the land is almost exclusively used for farming these animals, impressing the landscape a rural environment for excellence. Also tour the area some representatives of wildlife such as guanacos, foxes, and numerous species of birds.
As you continue south, the relief is starting to curl and spaces were some patches of forest, dotted with lakes. This area is known as "park Tierra del Fuego." Combine grassland vegetation typical of the north with the forest, the dominant vegetation in the southern landscape. The forest is distributed in clumps or patches, represented mainly by the ñire (Nothofagus antarctica) and valleys are occupied by small bogs. 're Going through the heart of the island, where the eponymous Provincial Reserve. Here they begin to alternate breaks livestock in forest undertakings and during the trip through this area, both along the National Route 3, as the complementary route No. 9 (Sector South), 16, 18 and 21 see succeed farms at (considerably smaller than the found further north) with small and medium sawmills. Also here you will surely see guanacos, foxes, and one begins to see the effects of beavers on the landscape.
The great natural boundary between North and South Island is the magnificent Lago Fagnano. A large valley glaciers eroded by water containing a body of freshwater, the largest in the archipelago, which marks a significant divide between the area North and South. The route begins to ascend the slopes of the Andes, which together with the sub-Antarctic and Magellanic forest dominate the landscape of the area. Tree species that represent it are the Lenga (Nothofagus pumilio), the cherry (Nothofagus betuloides) and to a lesser extent the ñire (Nothofagus antarctica), and referred to the north of Lago Fagnano, coexisting with smaller sized plant communities dominated by El Calafate (Berberis buxifolia) and black matte (Chiliotricum difussum). Throughout the broad and deep valleys also traverse bogs and valleys are seen cross relic glaciers thousands of years ago covered this mountainous landscape. Some peaks reach 1,500 m. and appreciated the precise boundary line of the forest covering the mountain slope to 650 m. on sea level. The National Highway No. 3 is the one crossing the mountains by the Garibaldi Pass (about 450 m above sea level). The route continues south and then west to come to an end within the National Park Tierra del Fuego, across the Provincial Land Reserve Staff and their final stretches along the coast of the Beagle Channel. This area is also crossed by the Provincial Highway No. 33, which extends eastward along the Beagle Channel and leading to breaks Harberton and Moat, to just over 110 km. the East of Ushuaia.
the fullest extent of the province , Highlights the wide variety of bird species. The most representative are: penguins, albatrosses, petrels, gulls, terns, cormorants, oystercatchers, sandpipers, ducks, grebes, geese, storks, vultures, condors, eagles, hawks and numerous species of birds (ovenbirds, flycatchers, etc..) each of them in the wild, adding about two hundred species.
terrestrial mammals from the guanaco, the red fox, rodents and the tuco-tuco and small field mice, among the natives, while the rabbit, gray fox, beaver, muskrat, mink and the hairy armadillo is the most common among those introduced and feral. You can include the red deer on Staten Island and reindeer in the archipelago of South Georgia, both introduced in the early twentieth century.
With regard to marine mammals throughout the Argentine Sea surrounding the Big Island and the Antarctic Peninsula, the most frequently sighted several species of seals, dolphins (including orca), bottlenose dolphins, whales and seals. Furthermore, along the Beagle Channel live sea otters, a threatened species under the IUCN Red List of Mammals Argentinos and vulnerable according to IUCN.
Los Andes cross our country in its entirety. In some Argentine provinces, "high mountain" involves making journeys of several hours by car, or perhaps demanding hikes, to overcome at least 2,000 m. height and reach above the upper limit of the forest and meet certain species of birds and flora, or with signs of recent glacial ice or even with themselves. The ecosystem that occurs from the upper limit of the forest is known as the "Andean desert."
Mountains near Ushuaia offer this ecosystem approach to virtually every visitor who wants it, almost without having to leave the city. For example, just 7 km. Ushuaia, and with help from a chairlift, it's easy approach to the Martial Glacier, just over 800 m. high. However, do not neglect all the safety aspects pertaining to a mountain out, so we suggest you check what are the conditions for your hiking or climbing with guaranteed success.
In the past, our territory has been covered by ice, a phenomenon known as ice. This is a process that includes the origin, movement and occupation of a surface by a huge mass of ice or a glacier. And in the surrounding small glaciers survive, testimony of that period, such as Martial. Once removed
bodies and rivers of ice, bare rock shaped was accompanied only by glacial deposits or shelters and small patches of vegetation that could survive while they lived with the ice and it was the seed to repopulate the area, thanks to the thin layer of soil that was formed
A FOREST most remarkable features of Tierra del Fuego forest for the forest is closer to Antarctica. It is also commonly called or sub-Antarctic Magellanic forest. A striking feature of the trees that consist mainly of the genus Nothofagus, is their ability to live in extremely harsh: a thin layer of soil (sometimes no more than 10 cm.) steep slopes, exposed to strong winds, with gusts over 100 km / h at times and a mean annual temperature (in the area of \u200b\u200bUshuaia) of 5 º C and rainfall ranging between 300 and 5000 mm. This is truly extreme and this forest grows there fagáceas, serving as support thousands of other living beings that form the ecosystem of very peculiar. Of the three species that comprise it, both are deciduous foliage: the Lenga (Nothofagus pumilio) and ñire (Nothofagus antarctica) and a perennial, called cherry or coihue de Magallanes (Nothofagus betuloides). There are other species of trees but are much less abundant.
The species under to use is mainly beech.
