Venezuela is located in the north of South America; geologically, its mainland rests on the South American Plate. It has a total area of 916,445 km2 (353,841 sq mi) and a land area of 882,050 km2 (340,560 sq mi), making Venezuela the 33rd largest country in the world. The territory it controls lies between latitudes 0° and 13°N and longitudes 59° and 74°W.
Shaped roughly like a triangle, the country has a 2,800 km (1,700 mi) coastline in the north, which includes numerous islands in the Caribbean and the northeast borders the northern Atlantic Ocean. Most observers describe Venezuela in terms of four fairly well-defined topographical regions: the Maracaibo lowlands in the northwest, the northern mountains extending in a broad east-west arc from the Colombian border along the northern Caribbean coast, the wide plains in central Venezuela, and the Guiana Highlands in the southeast.
The northern mountains are the extreme northeastern extensions of South America's Andes mountain range. Pico Bolívar, the nation's highest point at 4,979 m (16,335 ft), lies in this region. To the south, the dissected Guiana Highlands contain the northern fringes of the Amazon Basin and Angel Falls, the world's highest waterfall, as well as tepuis, large table-like mountains. The country's center is characterized by the llanos, which are extensive plains that stretch from the Colombian border in the far west to the Orinoco River delta in the east. The Orinoco, with its rich alluvial soils, binds the largest and most important river system of the country; it originates in one of the largest watersheds in Latin America. The Caroní and the Apure are other major rivers.
Venezuela borders Colombia to the west, Guyana to the east, and Brazil to the south. Caribbean islands such as Trinidad and Tobago, Grenada, Curaçao, Aruba, and the Leeward Antilles lie near the Venezuelan coast. Venezuela has territorial disputes with Guyana, formerly United Kingdom, largely concerning the Essequibo area and with Colombia concerning the Gulf of Venezuela. In 1895, after years of diplomatic attempts to solve the border dispute, the dispute over the Essequibo River border flared up. It was submitted to a "neutral" commission (composed of British, American, and Russian representatives and without a direct Venezuelan representative), which in 1899 decided mostly against Venezuela's claim.
Venezuela's most significant natural resources are petroleum and natural gas, iron ore, gold, and other minerals. It also has large areas of arable land and water.
Venezuela is entirely located in the tropics over the Equator to around 12° N. Its climate varies from humid low-elevation plains, where average annual temperatures range as high as 35 °C (95.0 °F), to glaciers and highlands (the páramos) with an average yearly temperature of 8 °C (46.4 °F). Annual rainfall varies from 430 mm (16.9 in) in the semiarid portions of the northwest to over 1,000 mm (39.4 in) in the Orinoco Delta of the far east and the Amazonian Jungle in the south. The precipitation level is lower in the period from November to April and later in the year from August to October . These periods are referred to as hot-humid and cold-dry seasons. Another characteristic of the climate is this variation throughout the country by the existence of a mountain range called "Cordillera de la Costa" which crosses the country from east to west. The majority of the population lives in these mountains.
The country falls into four horizontal temperature zones based primarily on elevation, having tropical, dry, temperate with dry winters, and polar (alpine tundra) climates, amongst others. In the tropical zone—below 800 m (2,625 ft)—temperatures are hot, with yearly averages ranging between 26 and 28 °C (78.8 and 82.4 °F). The temperate zone ranges between 800 and 2,000 m (2,625 and 6,562 ft) with averages from 12 to 25 °C (53.6 to 77.0 °F); many of Venezuela's cities, including the capital, lie in this region. Colder conditions with temperatures from 9 to 11 °C (48.2 to 51.8 °F) are found in the cool zone between 2,000 and 3,000 m (6,562 and 9,843 ft), especially in the Venezuelan Andes, where pastureland and permanent snowfield with yearly averages below 8 °C (46 °F) cover land above 3,000 meters (9,843 ft) in the páramos.
The highest temperature recorded was 42 °C (108 °F) in Machiques, and the lowest temperature recorded was −11 °C (12 °F), it has been reported from an uninhabited high altitude at Páramo de Piedras Blancas (Mérida state), even though no official reports exist, lower temperatures in the mountains of the Sierra Nevada de Mérida are known.
Venezuela lies within the Neotropic ecozone; large portions of the country were originally covered by moist broadleaf forests. One of 17 megadiverse countries, Venezuela's habitats range from the Andes Mountains in the west to the Amazon Basin rainforest in the south, via extensive llanos plains and Caribbean coast in the center and the Orinoco River Delta in the east. They include xeric scrublands in the extreme northwest and coastal mangrove forests in the northeast. Its cloud forests and lowland rainforests are particularly rich.
Animals of Venezuela are diverse and include manatees, three-toed sloth, two-toed sloth, Amazon river dolphins, and Orinoco crocodiles, which have been reported to reach up to 6.6 m (22 ft) in length. Venezuela hosts a total of 1,417 bird species, 48 of which are endemic. Important birds include ibises, ospreys, kingfishers, and the yellow-orange Venezuelan troupial, the national bird. Notable mammals include the giant anteater, jaguar, and the capybara, the world's largest rodent. More than half of Venezuelan avian and mammalian species are found in the Amazonian forests south of the Orinoco.
For the fungi, an account was provided by R.W.G. Dennis which has been digitized and the records made available on-line as part of the Cybertruffle Robigalia database. That database includes nearly 3,900 species of fungi recorded from Venezuela, but is far from complete, and the true total number of fungal species already known from Venezuela is likely higher, given the generally accepted estimate that only about 7% of all fungi worldwide have so far been discovered.
Among plants of Venezuela, over 25,000 species of orchids are found in the country's cloud forest and lowland rainforest ecosystems. These include the flor de mayo orchid (Cattleya mossiae), the national flower. Venezuela's national tree is the araguaney, whose characteristic lushness after the rainy season led novelist Rómulo Gallegos to name it "[l]a primavera de oro de los araguaneyes" (the golden spring of the araguaneyes).
Venezuela is among the top 20 countries in terms of endemism. Among its animals, 23% of reptilian and 50% of amphibian species are endemic. Although the available information is still very small, a first effort has been made to estimate the number of fungal species endemic to Venezuela: 1334 species of fungi have been tentatively identified as possible endemics of the country. Some 38% of the over 21,000 plant species known from Venezuela are unique to the country.
Venezuela is one of the 10 most biodiverse countries on the planet, yet it is one of the leaders of deforestation due to economic and political factors. Each year, roughly 287,600 hectares of forest are permanently destroyed and other areas are degraded by mining, oil extraction, and logging. Between 1990 and 2005, Venezuela officially lost 8.3% of its forest cover, which is about 4.3 million ha. In response, federal protections for critical habitat were implemented; for example, 20% to 33% of forested land is protected. The country's biosphere reserve is part of the World Network of Biosphere Reserves; five wetlands are registered under the Ramsar Convention. In 2003, 70% of the nation's land was under conservation management in over 200 protected areas, including 43 national parks. Venezuela's 43 national parks include Canaima National Park, Morrocoy National Park, and Mochima National Park. In the far south is a reserve for the country's Yanomami tribes. Covering 32,000 square miles (82,880 square kilometres), the area is off-limits to farmers, miners, and all non-Yanomami settlers.
Venezuela was one of the few countries that didn't enter an INDC at COP21.
