Forest Distribution

1. Forest Distribution in the World

Forest distribution across the world depends mainly on climate, relief, soil, and rainfall. Forests cover about 31% of Earth’s land area and are unevenly distributed. Tropical evergreen forests occur near the Equator, coniferous forests in high latitudes, temperate deciduous forests in mid-latitudes, Mediterranean forests in western continental margins, and montane forests in mountainous regions. These forests support biodiversity, regulate climate, prevent soil erosion, and maintain ecological balance. Human activities, urbanization, and deforestation have altered natural forest distribution in many regions. Understanding forest distribution is important for conservation, sustainable resource management, and environmental protection.

2. Tropical Evergreen Forests

Tropical evergreen forests, also known as tropical rainforests, are found in warm and humid regions near the Equator, generally between 10°N and 10°S latitudes. They receive heavy rainfall exceeding 200 cm annually and remain green throughout the year. These forests are dense, multi-layered, and rich in biodiversity. Major regions include the Amazon Basin, Congo Basin, and Southeast Asia. Common vegetation includes tall broad-leaved trees, lianas, palms, bamboo, and epiphytes. They provide habitat for numerous species such as elephants, monkeys, tigers, and birds. Tropical evergreen forests regulate climate, absorb carbon dioxide, and maintain the global water cycle.

3. Coniferous Forests (Taiga/Boreal Forests)

Coniferous forests, also called Taiga or Boreal forests, are found in sub-polar regions between 50°N and 70°N latitudes across North America, Europe, and Asia. They experience long, cold winters and short, cool summers. Trees are evergreen, cone-bearing, and possess needle-shaped leaves that reduce water loss. Common species include pine, spruce, fir, cedar, and hemlock. These forests form the largest terrestrial biome on Earth and play a significant role in carbon storage. Wildlife includes moose, bears, lynx, foxes, and reindeer. Coniferous forests are important sources of timber, paper pulp, and ecological stability.
