Páramo () may refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". A narrower term classifies the páramo according to its regional placement in the northern Andes of South America and adjacent southern Central America. The páramo is the ecosystem of the regions above the continuous forest line, yet below the permanent snowline. It is a "Neotropical high mountain biome with a vegetation composed mainly of giant rosette plants, shrubs and grasses". According to scientists, páramos may be "evolutionary hot spots", that meaning that it's among the fastest evolving regions on Earth. Location The Northern Andean Páramo global ecoregion includes the Cordillera Central páramo (Ecuador, Peru), Santa Marta páramo (Colombia), Cordillera de Merida páramo (Venezuela) and Northern Andean páramo (Colombia, Ecuador) terrestrial ecoregions. The Costa Rican páramo in Costa Rica and Panama is another páramo ecoregion. In the strictest sense of the term, all páramo ecosystems are in the Neotropics, specifically South and Central America. Scattered throughout the regions between 11°N and 8°S latitudes, these ecosystems are mainly in the northwest corner of South America, in Colombia, Ecuador, Peru, and Venezuela. In Venezuela, the páramo occurs in the Cordillera de Mérida. Páramo ecosystems are also found in the Sierra Nevada de Santa Marta in Colombia, and in the regions of Huehuetenango and El Quiché of Guatemala in the Sierra de los Cuchumatanes. The Cordillera de Talamanca of Costa Rica and the westernmost part of Panama has páramo. In northern Ecuador, the Guandera Biological Station is a fairly undisturbed páramo ecosystem. The majority of the páramo ecosystems occur in the Colombian Andes. The Sumapaz Páramo, south of the Altiplano Cundiboyacense in the Eastern Ranges of the Colombian Andes (about south of Bogotá), is the largest páramo in the world. This region was declared a National Park of Colombia in 1977 because of its importance as a biodiversity hotspot and main source of water for the most densely populated area of the country, the Bogotá Savannah. The Páramo Wildlife Refuge Park in the San José Province of Costa Rica "protects tropical forest areas in the high elevations of the Talamanca Mountains". Cotopaxi National Park contains of protected land in the Cotopaxi Province of Ecuador. Much of this park is páramo. Its flora includes gentians, clubmosses, valerians, and asters such
