The statistics presented in the International Forestry chapter of this release cover:
- woodland area;
- carbon stocks;
- wood removals;
- production and apparent consumption of wood products; and
- trade in forest products.
Data sources and methodology
International data on forest area and carbon stocks are obtained from the Global Forest Resources Assessment (FRA) 2010 (www.fao.org/forestry/fra/fra2010/en/), compiled by the United Nations Food and Agriculture Organisation (FAO). The information in Table 9.1 uses forest area from FRA 2010, excluding "other wooded land"; for the UK, this is very similar to the definition of "woodland" used in other tables.
International data on production, imports and exports are obtained from the FAO. Data are collected via the Joint Forest Sector Questionnaire for FAO and other international organisations and published on the FAOSTAT database (http://faostat.fao.org/).
Data on apparent consumption is derived as production plus imports less exports.
The UK data on forest area and carbon stocks are as submitted by the Forestry Commission to FAO in May 2009. More recent estimates of UK woodland area are provided in the Chapter on Woodland Area and Planting. A copy of the full UK return for the Forest Resources Assessment is available at www.forestry.gov.uk/forestry/infd-7z8k3k
The UK data on production, imports and exports are as submitted by the Forestry Commission to Eurostat in September 2013. More recent UK estimates are provided in the Chapters on UK-grown Timber and Trade. Copies of all UK returns for the Joint Forest Sector Questionnaire are available at www.forestry.gov.uk/forestry/infd-7aqhzh
International statistics compiled from FRA are not subject to revision after publication.
International statistics compiled from FAOSTAT may be subject to revision after publication if revisions are made to the data produced by individual countries.
Revisions to historical data have been made in the FAOSTAT database since the publication of "Forestry Statistics 2013" (Tables 9.4 to 9.6). The largest revision resulted in an increase in industrial roundwood removals in the Asia region across all years shown in Table 9.4.
The Forestry Commission’s revisions policy sets out how revisions and errors to these statistics are dealt with, and can be found at: www.forestry.gov.uk/pdf/FCrevisions.pdf/$FILE/FCrevisions.pdf
Statistics on international forestry are reported here at a regional level. Further data (including figures for individual countries) are also available from the original sources (see above).
Information on the Global Forest Resources Assessment 2015 is available on the FAO website at www.fao.org/forestry/fra/76871/en/
The United Nations Economic Commission for Europe (UNECE) Committee on Forests and the Forest Industry (previously the UNECE Timber Committee) also collects, on an annual basis, estimates for the current year and projections for the following year of wood production, imports and exports. Results are available on the UNECE website (www.unece.org/forests/fpm/timbercommittee.html). Copies of UK returns for the UNECE Timber Forecast Questionnaire are available at www.forestry.gov.uk/forestry/infd-7aqjql

UK data for the Global Forest Resources Assessment 2015 will be released on 30 October 2014.
International data on wood production and trade in 2013 will be released on 24 September 2015 in "Forestry Statistics 2015" and "Forestry Facts & Figures 2015".
