In November 1971, at the request of the European Confederation of Agriculture, FAO'S member governments supported the annual observance of 21 March as World Forestry Day.
Preparations have already started for the world-event in 2013.
The UN International Day of Forests invites all Member States to hold, in connection to this international day, awareness-raising events on activities related to our forests.
