The Llanos is a big, flat land. It is in South America. It sits in Colombia and Venezuela.
A large river called the Orinoco flows through it. The land has much grass and some trees. Sometimes, the land gets very wet. This happens during the rainy season.
Rain makes the land flood. This creates new homes for water birds. You might see a scarlet ibis there. Many big cats like the jaguar live here too.
People herd many cows on the grass. They also find oil deep in the ground. The Llanos is a very busy place.
The Llanos is a vast plain in South America.
It sits in Colombia and Venezuela. To the west, the Andes mountains rise up. To the north, you will find the Venezuelan Coastal Range. The Orinoco River flows through the middle. This river runs from west to east. It helps form the border between the two countries.
The weather has two main parts. There is a rainy season from April to November. Then comes a dry season from December to March. During the wet months, the land can flood. The water can rise up to one meter high. This creates wetlands for many animals.
You might see many animals here. Large cats like jaguars and pumas live in the forests. You can also find giant anteaters and capybaras. Water birds, like the scarlet ibis, live in the wet areas.
People use the land in many ways. Many people herd cattle on the grass. These workers are called llaneros. People also grow crops like rice and maize. Deep in the ground, there are large deposits of oil. This is part of the Orinoco Belt.
The Llanos is a huge area of tropical grasslands and savannas. It sits in northwestern South America. This region spans across Colombia and Venezuela. To the west, the Andes mountains form a high border. The Venezuelan Coastal Range sits to the north. To the southeast, you will find the Guiana Highlands. The Orinoco River is the main river of this place. It flows from west to east through the plains. This large river also helps form the border between Colombia and Venezuela.
The weather in the Llanos follows a seasonal pattern. It has a tropical savanna climate. There is a rainy season from April to November. The wettest months are usually June and July. After the rain, a dry season begins in December. It lasts until March. During the rainy season, the land can flood quite a bit. Water can rise up to one meter high in some areas. These seasonal floods turn the grasslands into temporary wetlands. This creates a special home for many different water birds.
Plants and animals live in many different parts of the Llanos. Some areas are called llano alto, which stay dry all year. These places have grasses and shrubs that grow about 30 to 100 cm high. Other areas are called llano bajo, which flood during the rains. These flooded lands have richer soils. You might see trees like the manteco or the chaparro growing there. Many animals call this place home. You can find giant anteaters, capybaras, and white-tailed deer. Large cats like jaguars and pumas also live in the forests.
People have lived and worked in the Llanos for a long time. Since the Spanish colonial era, many people have herded cattle here. The workers who take care of the herds are called llaneros. This name is similar to the gauchos of the Pampas. Today, people also use the land for farming rice and maize. Some farmers even grow rice in former seasonal wetlands. The governments of Venezuela and Colombia also work in the oil and gas industry. Large amounts of oil are found in the Orinoco Belt.
Protecting this large region is very important for nature. A study in 2017 showed that 28% of the area is protected. This covers about 105,323 square kilometers. In Venezuela, there are places like Aguaro-Guariquito National Park. Another protected area is the Cinaruco-Capanaparo National Park. Colombia also has the El Tuparro National Natural Park. These parks help keep the plants and animals safe. Many special animals, like the long-nosed armadillo, live only in the Llanos.
The Llanos is a vast ecoregion of tropical grasslands, savannas, and shrublands. It is located in northwestern South America. This massive plain spans across parts of Colombia and Venezuela. To the west and northwest, the Andes mountains form a high boundary. The Venezuelan Coastal Range borders the region to the north. To the southeast lie the Guiana Highlands. To the southwest, you will find the Negro-Branco moist forests. The Orinoco River is the central feature of this landscape. It flows from west to east through the plains. This river system also helps form the border between Colombia and Venezuela.
The climate of the Llanos follows a distinct seasonal pattern. It features a tropical savanna climate. In the Colombian Llanos, this can transition into a tropical monsoon climate. Rainfall is highly seasonal. A rainy season occurs from April to November. The wettest months are typically June and July. This is followed by a dry season from December to March. Rainfall amounts vary across the region. In Apure State in the southwest, rainfall can reach high levels. Monagas State in the northeast also sees significant precipitation. The mean annual temperature remains relatively consistent throughout the year.
The landscape is divided into different types of terrain based on water levels. One type is the llano alto. These are grasslands and savannas that remain dry all year. They cover about two-thirds of the Venezuelan Llanos. These areas feature grasses and shrubs that grow between 30 and 100 cm high. They often form small clumps called tussocks. The soil here is typically sandy and low in nutrients. Another type is the llano bajo. These are seasonally flooded grasslands and savannas. During the rainy season, water can rise up to one meter. This flooding creates temporary wetlands similar to the Pantanal in South America. These flooded areas usually have richer soils.
Vegetation in the Llanos is diverse and adapts to these water changes. In the dry llano alto, grasses like Trachypogon are very common. Shrubs are often legumes from genera such as Mimosa or Cassia. Trees like the manteco or chaparro grow in scattered groups or small patches called matas. In the flooded llano bajo, you will find the Paspalum fasciculatum grass. The moriche palm is a key feature of the morichales, which are seasonally flooded forests. Along rivers, gallery forests provide more dense cover. These include evergreen forests or semi-deciduous forests on higher ground. Semi-deciduous forests have a canopy height of 12 to 15 meters. Some areas also feature matorrales, which are shrublands reaching 5 to 8 meters high.
A wide variety of animals inhabit these different environments. Mammals in the open savannas include white-tailed deer, giant anteaters, and capybaras. You might also see the giant armadillo or the Eastern cottontail. The gallery forests support more diverse large mammals. These include tapirs, peccaries, and various monkeys like the capuchin. Large cats such as the puma, jaguar, and ocelot are also present. The Llanos are home to some of the largest jaguars in the world. Male jaguars here can average over 95 kg. The Orinoco River supports the endangered giant otter. Some animals, like the long-nosed armadillo, are endemic to the Llanos. This means they are found nowhere else on Earth.
Human activity has shaped the Llanos for centuries. Since the Spanish colonial era, cattle herding has been the main economic activity. The workers who manage these herds are known as llaneros. This culture is similar to the gauchos of the Pampas. Decades of cattle raising have changed the local ecology. Grasslands are often burned to remove trees and make grazing easier. Non-native grasses, such as the African grass Melinis minutiflora, have been introduced for fodder. Agriculture has also expanded, with rice and maize being grown in large areas. Some rice fields are located in former seasonal wetlands.
The region is also vital for its natural resources. The governments of Venezuela and Colombia have developed large oil and gas industries. In Venezuela, the Orinoco Belt contains massive deposits of extra heavy crude. These oil sands are one of the largest in the world. They sit behind the Athabasca Oil Sands in Canada. Venezuela's non-conventional oil deposits are estimated at about 300 billion barrels. This amount is roughly equal to the world's conventional oil reserves. To protect this complex system, much of the land is conserved. A 2017 assessment found that 105,323 km², or 28%, of the ecoregion is in protected areas. This includes several national parks in both Colombia and Venezuela.
