International Day of Forests
Forests are the lungs of our planet — breathe in their importance.
About
The International Day of Forests on March 21 celebrates and raises awareness of the importance of all types of forests. Forests cover 31% of the global land area and are home to more than 80% of terrestrial species. They absorb CO₂, produce oxygen, regulate water cycles, and sustain livelihoods for 1.6 billion people worldwide. Yet every year, 10 million hectares of forest are lost. Each year the day focuses on a new theme, from forests and health to forests and biodiversity.
History
The United Nations Forum on Forests and the Food and Agriculture Organization (FAO) established March 21 as the International Day of Forests through the UN General Assembly in November 2012. The date corresponds to the vernal equinox in the Northern Hemisphere — a date long associated with nature's renewal. The first official observance was held in 2013.
Where It's Observed
Cultural Context
US United States
The US observes the day through the National Forest Foundation, USDA Forest Service events, and reforestation campaigns. American forests cover about 750 million acres, but deforestation through logging and development remains an ongoing policy debate.
KR South Korea
South Korea achieved one of history's most remarkable reforestation successes — going from a nearly deforested nation after the Korean War to 64% forest coverage by 2020. The day celebrates this achievement and ongoing efforts to protect remaining old-growth stands.
JP Japan
Japan — 68% forested — has a deep cultural reverence for forests, expressed in Shinrin-yoku (forest bathing). The day draws attention to the challenge of managing aging sugi (Japanese cedar) plantations and the need for sustainable forestry practices.
