context_page_description: Nahuel Huapi National Park is the oldest national park in Argentina, established in 1934. It surrounds Nahuel Huapi Lake in the foothills of the Patagonian Andes. The largest of the national parks in the region, it has an area of 7,050 km², or nearly 2 million acres. Its landscapes represent the north Patagonian Andean Zone consisting of three types, namely, the Altoandino, the Andino-Patagónico and the Patagonian steppe. It also represents small parts of the Valdivian Rainforest.
  The park and the reserve lie at an altitude of 720–3,574 metres, and are designated under IUCN management categories II and IV. The park is completely protected while the reserve is partially protected. The national park is dominated by the high mountain chain of the Andes, many lakes, rapid rivers, waterfalls, snow-clad peaks, glaciers and extensive forests. It is bordered by Chile on its western side.
context_section_description: The park's ecology consists of Patagonian steppe at lower elevations and Valdivian temperate forests at higher elevations. It is notable for its rich wildlife due to its many biotopes, attributed to the varied altitude and precipitation range.
  Plants
  Xerophytic Patagonian flora is dominant in the eastern half of the park while the western half is covered profusely with temperate rain forests. The dominant tree species in the park are the lengas, coihue, and the ñires. Other varieties of trees seen in the park are the Chilean cedar (Austrocedrus chilensis), Winter's bark (Drimys winteri),  Myrceugenella apiculata, Lomatia ferruginea, Lomatia hirsuta, Alstroemeria aurantica, Fuchsia megellanica, bamboo Chusquea culcou, Mitraria cocinea and Embothrium coccineum.

The Valdivian rain forests is well forested with fine arrayan trees with crumbling bark. In the high rain fall zones close to the Chilean border there is profusion of 450-year-old coihue trees (small leaved evergreen beeches). alerce South American Spanish name) of 1500 year vintage are seen spread throughout the park. Bamboo cane grows in abundance.

These genera are Cnesia, Cnesiamima, Gigantodax, Paraustrasimulium, and Simulium (Pternaspatha),  a subgenus of Simulium with 19 species; these account for 57% of the Simuliidae fauna found in Argentina.
  Nahuelito is a lake monster named after the Nahuel Huapi Lake as its sighting in the lake is reported widely. Whether it is a fact or fiction, its sighting has been reported by local people and tourists with widely varying descriptions mentioning a “giant water snake with humps and fish-like fins to a swan with a snake's head, the overturned hull of a boat, and the stump of a tree”. Its length is also reported in the range of 15–150 feet (4.6–45.7 m).
