Colombia is one of the most biodiverse countries on Earth, and its rich ecological and geographical diversity has earned it a place among the world's megadiverse nations. The country's diverse landscapes, which include tropical rainforests, high mountain ranges, coastal regions, and vast river systems, contribute to its exceptional biodiversity.
Due to its variety of ecosystems, Colombia is among the top three countries on the planet in terms of biodiversity. According to the Global Biodiversity Index, with its 1,863 bird species, 812 amphibian species, 2,105 fish species, 477 mammal species, 634 reptile species, and 24,025 plant species, Colombia is one of 17 megadiverse countries.
Conservation
Conservation in Colombia is a critical and ongoing effort to protect the country's exceptional biodiversity, unique ecosystems, and natural resources. Colombia is renowned for its rich ecological diversity, including tropical rainforests, high mountain ranges, coastal regions, and extensive river systems. These ecosystems are home to numerous endemic species.
Challenges to conservation in Colombia include illegal armed groups, land conflicts, illicit crop cultivation, and the socio-economic pressures that drive deforestation and land degradation. Despite these challenges, Colombia's commitment to protecting its unique natural heritage remains strong, and the country continues to make significant efforts to conserve its biodiversity and promote sustainable development.
Climate
Colombia's climate is tropical along the coast and the eastern lowlands and cooler in the highlands and Andes. However, the country's proximity to the equator minimizes temperature variations throughout the year.
Colombia generally experiences warm, humid weather year-round. The mean annual temperature is 24 °C (75 °F), and the average humidity is 70%. However, the climate in Colombia varies greatly depending on the region due to the country's diverse topography.
Colombia can be divided into five main climate zones:
-
Tierra Caliente (hot zone): This zone is located at sea level and up to 1,000 m (3,280 ft) above sea level. It is characterized by hot, humid weather with temperatures ranging from 24 - 32 °C (75 - 90 °F).
-
Tierra Templada (temperate zone): This zone is located 1,000 - 2,000 m (3,280 - 6,560 ft) above sea level. It is characterized by mild, pleasant weather with temperatures ranging from 18 - 24 °C (64 - 75 °F).
-
Tierra Fría (cold zone): This zone is 2,000 - 3,000 m (6,560 - 9,840 ft) above sea level. It is characterized by cool weather with temperatures ranging from 13 - 18 °C (55 - 64 °F).
-
Tierra Helada (frozen zone): This zone is above 3,000 m (9,840 ft) above sea level. It is characterized by cold weather below 13 °C (55 °F).
-
Páramos: These are high-altitude grasslands above 3,500 m (11,480 ft) above sea level. Cold weather, strong winds, and high humidity characterize them.
Colombia also has two main seasons: the wet season and the dry season. The wet season runs from April to May and October to November, and the dry season runs from December to January and July to August. However, the timing and duration of the wet and dry seasons vary depending on the region.

Natural Geography of Colombia
Natural Regions
Colombia generally classifies its geographic landscape into six natural regions:
-
Caribbean Region: in the north
-
Pacific/Chocó Region: in the west
-
Andean Region: at the center
-
Orinoco Region: in the east
-
Amazon Region: in the south
-
Insular Region: in the Caribbean Sea and the Pacific Ocean
Caribbean Region
The Caribbean Natural Region stretches from the Gulf of Uraga in the west to the Guajira Peninsula in the east. The region also hosts the historic port cities of Cartagena and Santa Marta, the first areas settled by the Europeans.
The natural region is traversed by rivers that flow from the Andean highlands and empty into the Caribbean Sea, including the Magdalena, Colombia's principal waterway.
Ecosystems include humid forests, dry forests, savannas, wetlands, the Sierra Nevada de Santa Marta mountain range and the Guajira Desert.
The Caribbean coast has a hot and humid climate year-round. The average temperature is 27 °C (81 °F), and the average humidity is 80%. The wet season runs from May to November, and the dry season runs from December to April.
Pacific/Chocó Region
The Pacific/Chocó Natural Region, also known as the "Colombian Chocó," comprises an area of approximately 75,000 sq km (29,000 sq mi) on the west coast of Colombia. The terrain is mostly flat and covered by dense rainforests, rivers, swamps, and mangroves. Some areas experience rainfall rates that are among the highest in the world.
The Pacific Ocean borders the region on the west and the Cordillera Occidental of the Colombian Andes to the east. To the south is the border with Peru. To the north is the Darién Gap and the border with Panama.
Ecologically, the region belongs entirely to the Chocó Biogeographic Region and is part of the Tumbes-Chocó-Magdalena hotspot. Due to a combination of evolutionary, ecological, climatic, and geologic factors, this region presents the highest biodiversity concentration per area in the world.
Between 7,000 and 8,000 of the 45,000 species registered in Colombia are found in the Chocó. Endemic plant species total more than 2,000, while endemic birds comprise more than 100 species, representing the highest endemism levels on the planet.
The Pacific coast has a warm and humid climate year-round. The average temperature is 26 °C (79 °F), and the average humidity is 85%. The wet season runs from May to November, and the dry season runs from December to April.
Andean Region
The Andean Natural Region is the most populated natural region of Colombia. Along with its many mountains, it contains most of the country's urban centers. These urban centers were also the location of the most significant pre-Columbian indigenous settlements.
The Andean region also hosts a significant portion of the Magdalena River and basin, the most important in Colombia regarding economic and environmental significance.
North of the Colombian Massif in the extreme southwest, the Colombian Andes divide into three parallel mountain chains:
-
Cordillera Occidental: the western range runs adjacent to the Pacific coast and is home to the city of Cali
-
Cordillera Central: the middle range runs up the center of the country between the Cauca and Magdalena river valleys
-
Cordillera Oriental: the eastern range extends northeast towards the Guajira Peninsula and includes the cities of Bogotá, Bucaramanga, and Cúcuta
The Andes Mountains have a cooler climate than the coast, with temperatures varying depending on the altitude. The average temperature in the temperate zone is 18 °C (64 °F), and the average temperature in the cold zone is 13 °C (55 °F). The wet season runs from April to May and October to November, and the dry season runs from December to January and July to August.
Orinoco Region
The Orinoco (or Orinoquía) Natural Region is part of the Llanos, a vast tropical grassland plain situated east of the Andes. The region belongs to the Orinoco River watershed.
The sparsely populated region is rich in oil and suitable for extensive ranching. The region's ecosystems are tropical savanna with gallery forests and wetlands along the rivers.
Amazon Region
The Amazon Natural Region is located in southern Colombia and the Amazon Basin. Mostly covered by tropical rainforest, it covers approximately 35% of Colombia's territory.
The region is bounded west by the Cordillera Oriental of the Colombian Andes and extends to the Venezuelan and Brazilian borders in the east.
The Amazon rainforest has a hot and humid climate year-round. The average temperature is 27 °C (81 °F), and the average humidity is 90%. The wet season runs from October to May, and the dry season runs from June to September.
Insular Region
Some consider the Insular Region not a natural but a geopolitical region of Colombia. It comprises the areas outside the continental territories of the country, some of which are sometimes classified with the Caribbean Natural Region instead.
The Insular Region includes the Archipelago of San Andres, Providencia and Santa Catalina in the Caribbean Sea, Malpelo Island, and Gorgona Island in the Pacific Ocean.
Its subregions include other groups of islands:
-
Archipiélago de San Bernardo (in the Morrosquillo Gulf, Caribbean).
-
Islas del Rosario (Caribbean)
-
Isla Fuerte (Caribbean)
-
Isla Barú (Caribbean)
