The Bosque Andino Patagónico is a type of temperate to cold forest located in southern Chile and western Patagonia in Chile and Argentina at the southern end of South America. The climate here is influenced by humid air masses moving in from the Pacific Ocean which lose most of their moisture as they rise over the Andes. The flora is dominated by trees, usually of the ''Nothofagus'' genus. ==Geography== The Bosque Andino Patagónico represents one of the few relatively undisturbed temperate forests that has been little changed by man. It occupies approximately 6.5 million hectares of land. It is culturally significant because of its archaeological and historical value.〔 The Andean Patagonian forest region is located between 37°S and 55°S latitude, and clothes both sides of the Cordillera. The forest extends for about parallel to the Pacific coast, extending from just south of Mendoza in Argentina to the southern end of Santa Cruz Province and to the island portion of the province of Tierra del Fuego. It is a narrow strip of land, with a maximum width of , dwindling to zero in places near the Chubut River and Santa Cruz Province. It is bounded to the east by the Patagonian Desert. Ecologically the forest have no equivalent in the northern hemisphere. This is indebted to distinct biota histories and environmental differences.〔Veblen 2007, p. 217〕 The forest is divided into four regions; deciduous forest, Magellan forest, Valdivia forest and Del Pehuén. Rainfall is more plentiful in the Andean area than in other parts of Patagonia and there are several lakes, reservoirs and hydro-electric projects within the forested area. There is also an increase in population in nearby urban areas and greater tourism in the forest, resulting in increasing pollution.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bosque Andino Patagónico」の詳細全文を読む スポンサード リンク
