International Day of Forests - March 21
(Last Updated On: March 15, 2023)


Each year on March 21st, the International Day of Forests celebrates and raises awareness of the importance of all types of forests.

Forests cover one-third of the Earth’s landmass. Around 1.6 billion people depend on forests for their livelihood, medicines, fuel, food, and shelter. Forests are also home to more than 80 percent of land animals, insects, and plants. There are 3 trillion trees in all the forests on Earth. Forests are defined as a large group of trees. In order to be considered an actual forest, trees have to cover at least 0.5 hectares.

The three primary types of forests include:

  • Tropical: temperatures range from 68 to 77 degrees F. and receives 100 inches of rain a year
  • Temperate: broken down into two subcategories including temperate deciduous and temperate coniferous
    • Found in China, Japan, and the Eastern United States and Canada, temperate deciduous forests receive between 30 to 60 inches of rain a year.
    • Look for temperate coniferous forests in New Zealand, South America, and Pacific Northwestern United States and Canada. They receive between 50 and 200 inches of rain a year.
  • Boreal: Also known as Taiga forests, they grow in cold climates, such as Siberia, Canada, and Scandinavia. They receive between 15 and 40 inches of precipitation a year.

All forests contribute to the Earth’s ability to maintain its climate. Forests also help prevent soil erosion and act as water filters. Besides providing food and raw materials, forests promotes ecotourism and help make our planet look more beautiful.
