The United Nations General Assembly proclaimed 21 March the International Day of Forests in 2012. The organizers are the United Nations Forum on Forests and the Food and Agriculture Organization of the United Nations (FAO), in collaboration with Governments, the Collaborative Partnership on Forests and other relevant organizations in the field. The Day celebrates and raises awareness of the importance of all types of forests. On each International Day of Forests, countries are encouraged to undertake local, national and international efforts to organize activities involving forests and trees, such as tree planting campaigns. The theme for each International Day of Forests is chosen by the Collaborative Partnership on Forests. More details: https://www.un.org/en/observances/forests-and-trees-day
