About International Day of Forests

Forests cover about one third of the world’s land mass. Roughly 1.6 billion people, including more than 2000 indigenous cultures, depend on forests for their livelihood. Forests are vital to the planet for many reasons, including:

• Providing shelter for more than half of the terrestrial species of animals, plants and insects.
• Contributing to the balance of oxygen, carbon dioxide and humidity in the air.
• Protecting watersheds, which supply fresh water to rivers.

The UN first celebrated the International Day of Forests on March 21, 2013. This initiative follows from the International Year of Forests.
