The Llanos de Moxos, also known as the Beni savanna or Moxos plains, is a tropical savanna ecoregion of the Beni Department of northern Bolivia.
The Llanos de Moxos covers an area of 126,100 square kilometers (48,700 sq mi) in the lowlands of northern Bolivia, with small portions in neighboring Brazil and Peru. Most of the Llanos de Moxos lies within the departments of El Beni, Cochabamba, La Paz, Pando, and Santa Cruz. The Llanos de Moxos occupies the southwestern corner of the Amazon basin, and the region is crossed by numerous rivers that drain the eastern slope of the Andes Mountains. The low relief of the savannas, coupled with wet season rains and snowmelt from the Andes, cause up to half the land to flood seasonally.
The Llanos de Moxos is surrounded by tropical moist forests; the Southwestern Amazonian moist forests to the north, west, and south, and the Madeira-Tapajós moist forests to the east.
The climate of the Llanos de Moxos is tropical, with pronounced wet and dry seasons. The wet season generally extends from December to May, and annual rainfall ranges from 1300 mm in the east to 2500 mm in the west.
The ecoregion comprises a mosaic of savannas and wetlands, with islands of forest and gallery forests along rivers. Flooding and fire are important ecological factors.
The ecoregion is home to the blue-throated macaw (Ara glaucogularis), which is critically endangered.
The Llanos de Moxos was the setting for pre-Columbian agriculture, and appears to have been an early center of plant domestication. The inhabitants constructed agricultural earthworks: raised fields, causeways, canals, and about 4700 forested mounds over a 50,000 square kilometer area. Construction lasted from about 8850 BCE to about 1450 CE. Cultivation included manioc from about 8350 BCE, squash from about 8250 BCE, and maize from about 4,850 BCE. Several domestic crops, including manioc, squash, peanut, some varieties of chili and some beans, are genetically very close to wild species living in the Llanos de Moxos, suggesting that they were domesticated there. [3] The people made decorated pottery, wove cotton cloth, and in some places buried their dead in large urns.
Although Europeans arrived in South America in the late 15th century, they did not come to settle in the Llanos de Moxos until the late 17th century. The missions established by Jesuit missionaries in the 17th and 18th centuries became many of the modern towns in the region.
Since the 1950s, ranching has become the most important industry, and ranches dominate the landscape.
The Jesuit Missions of Moxos are located in the Llanos de Moxos, while the Jesuit Missions of Chiquitos are in the Chiquitania region to the southeast. [4]
A 2017 assessment found that 96,126 km2, or 77%, of the ecoregion is in protected areas. [2]
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone.
The Global 200 is the list of ecoregions identified by the World Wide Fund for Nature (WWF), the global conservation organization, as priorities for conservation. According to WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species dynamics, and environmental conditions". For example, based on their levels of endemism, Madagascar gets multiple listings, ancient Lake Baikal gets one, and the North American Great Lakes get none.
Chiquitania is a region of tropical savannas in the Santa Cruz Department in eastern Bolivia.
The Llanos is a vast tropical grassland plain situated to the east of the Andes in Colombia and Venezuela, in northwestern South America. It is an ecoregion of the tropical and subtropical grasslands, savannas, and shrublands biome.
When the Spanish arrived, they divided Peru into three main regions: the coastal region, that is bounded by the Pacific Ocean; the highlands, that is located on the Andean Heights, and the jungle, that is located on the Amazonian Jungle. But Javier Pulgar Vidal, a geographer who studied the biogeographic reality of the Peruvian territory for a long time, proposed the creation of eight Natural Regions. In 1941, he presented his thesis "Las Ocho Regiones Naturales del Perú" at the III General Assembly of the Pan-American Institute of Geography and History.
The Mojeños, also known as Moxeños, Moxos, or Mojos, are an indigenous people of Bolivia. They live in south central Beni Department, on both banks of the Mamore River, and on the marshy plains to its west, known as the Llanos de Mojos. The Mamore is a tributary to the Madeira River in northern Bolivia.
The Chiquitano dry forests is a tropical dry broadleaf forest ecoregion in Bolivia and Brazil. The ecoregion is named for the Chiquitano people who live in the region.
The Jesuit Missions of Chiquitos are located in the Santa Cruz department in eastern Bolivia. Six of these former missions collectively were designated as a UNESCO World Heritage Site in 1990. Distinguished by a unique fusion of European and Amerindian cultural influences, the missions were founded as reductions or reducciones de indios by Jesuits in the 17th and 18th centuries to convert local tribes to Christianity.
William Maxfield Denevan is an American geographer. He is professor emeritus of Geography at the University of Wisconsin-Madison and is a prominent member of the Berkeley School of cultural-historical geography. He also worked in the Latin American Center and the Institute for Environmental Studies at Wisconsin. His research interests are in the historical ecology of the Americas, especially Amazonia and the Andes.
The Chiquitano or Chiquitos are an indigenous people of Bolivia, with a small number also living in Brazil. The Chiquitano primarily live in the Chiquitania tropical savanna of Santa Cruz Department, Bolivia, with a small number also living in Beni Department and in Mato Grosso, Brazil. In the 2012 census, self-identified Chiquitanos made up 1.45% of the total Bolivian population or 145,653 people, the largest number of any lowland ethnic group. A relatively small proportion of Bolivian Chiquitanos speak the Chiquitano language. Many reported to the census that they neither speak the language nor learned it as children. The Chiquitano ethnicity emerged among socially and linguistically diverse populations required to speak a common language by the Jesuit Missions of Chiquitos.
The Llanos de Moxos, also known as the Moxos plains, are extensive remains of pre-Columbian agricultural societies scattered over the Moxos plains in most of Beni Department, Bolivia. The remains testify to a well-organized and numerous indigenous people. This contradicts the traditional view of archaeologists, notably Betty Meggers, who asserted that the Amazon River Basin was not environmentally able to sustain a large population and that its indigenous inhabitants were hunter-gatherer bands or slash-and-burn farmers. In the 1960s, petroleum company geologists and geographer William Denevan were among the first to publicize the existence of extensive prehistoric earthworks constructed in the Amazon, especially in the Llanos de Moxos.
The Caquetá moist forests (NT0107) is an ecoregion of tropical moist broad leaf forest to the east of the Andes in the east of Colombia, with a small section in Brazil, in the Amazon biome. The forests are in the transition between the Guiana and Amazon regions, and have highly diverse flora and fauna. They are relatively intact, although they are mostly unprotected and are threatened with deforestation to create cattle pastures.
The Mato Grosso tropical dry forests (NT0140), also called the Mato Grosso seasonal forests, is an ecoregion in central Brazil to the south of the Amazon region. It contains vegetation in the transition between the Amazon rainforest to the north and the cerrado savanna to the south. The opening of highways through the region has caused rapid population growth, deforestation and pollution.
The Apure–Villavicencio dry forests (NT0201) is an ecoregion in Venezuela and Colombia to the east of the eastern cordillera of the Andes. The ecoregion covers the transition zone between montane forests in the Andes and the llanos, or lowland grasslands. It has been severely degraded by deforestation, farming and ranching. The remnants are poorly protected.
The Jesuit Missions of Moxos are located in the Llanos de Moxos of Beni department in eastern Bolivia. Distinguished by a unique fusion of European and Amerindian cultural influences, the missions were founded as reductions or reducciones de indios by Jesuits in the 17th and 18th centuries to convert local tribes to Christianity.
The Mamoré–Guaporé linguistic area is a linguistic area that includes over a dozen South American language families and isolates of the Mamoré–Guaporé region of eastern lowland Bolivia and Brazil.
Forest islands are atypical isolated stands of tropical forest on the Amazonian savanna. Their origin is largely unknown. One hypothesis suggests anthropomorphic origins, those forest islands being earlier human farming of diverse useful, food-producing tropical plants and trees, collected and willfully inserted in suitable points of the grassland.
