FAOSTAT–Forestry provides annual production and trade estimates for numerous forest products, primarily wood products such as roundwood, sawnwood, wood panels, pulp and paper. For many forest products, historical data are available from 1961. These estimates are provided by countries through an annual survey conducted by FAO Forestry Department in partnership with the International Tropical Timber Organization (ITTO), the Statistical Office of the European Union (Eurostat) and the UN Economic Commission for Europe (UNECE). In the cases where countries have not provided information through the questionnaire, FAO estimates annual production based on trade journal reports, statistical yearbooks or other sources. Where data are unavailable, FAO repeats historical figures until new information is found. The Forestry domain covers: - Forestry production and trade - forest products production, import and export statistics from 1961 onwards; - Forestry trade flows - forest products bilateral trade statistics from 1997 onwards
