Introduction

This page provides high level information on the sources of the timber statistics presented in Chapter 2; more detailed information is provided on the following pages.

The chapter covers wood production (removals) from UK woodland, and consumption and production by primary wood processors in the UK. The timber statistics presented cover both softwood (wood from coniferous trees such as spruce, pine and larch) and hardwood (wood from non-coniferous trees such as oak, birch and beech). Please refer to the Glossary for an explanation of the terms used.

Quanitities of wood can be expressed in different units. Conversion factors can be used to convert between units.

Data sources and methodology

Statistics on timber are obtained from a number of sources. For wood production (removals), data are compiled from:

  • Forestry Commission (FC) and Forest Service (FS) administrative records of removals from FC/FS woodlands;

  • the Private Sector Softwood Removals Survey for softwood removals from non-FC/FS woodlands and

  • deliveries of hardwood to wood processing industries (see below) for total hardwood removals.

There is no source of data for hardwood removals from non-FC/FS woodlands, so these are estimated to be:

  • deliveries of hardwood to wood processing industries (see below) less

  • hardwood removals from FC/FS woodlands.

Softwood availability forecasts are obtained from the "UK 25-Year Forecast of Softwood Availability", released in July 2012 and available at www.forestry.gov.uk/forestry/infd-89zffj

Deliveries are estimated from the following sources:

  • the Sawmill Survey;

  • the Wood Panel Industries Federation (for wood-based panels);

  • the UK Forest Products Association (for integrated pulp and paper mills);

  • the Confederation of Paper Industries (for paper production);

  • the Survey of Round Fencing Manufacturers;

  • the Private Sector Softwood Removals Survey (for softwood deliveries to woodfuel);

  • shavings manufacturers;

  • companies believed to export roundwood and/or chips.

Estimates are also provided by the Expert Group on Timber and Trade Statistics: www.forestry.gov.uk/forestry/infd-5rabj3

Quality

The figures in this publication are final.

Detailed information on the quality of the statistics presented in this publication is available in the "Quality Report: UK Wood Production and Trade" at: www.forestry.gov.uk/pdf/ukwptqrpt.pdf/$FILE/ukwptqrpt.pdf

Further quality information on FC Official Statistics, including separate reports for each of the industry surveys used in this release, is available at:

Revisions

Figures for 2011 and earlier years have been previously published. They are however subject to revisions from those published in "UK Wood Production and Trade: 2011 provisional figures" and previous publications, to reflect late updates to administrative or survey data. Further details on any revisions made are provided in the following pages.

Information on significant revisions to published statistics is provided in the quality report on UK Wood Production and Trade, available from our Quality web page at www.forestry.gov.uk/forestry/infd-7zhk85.

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.

Further information

Most of these statistics are used to compile data that are sent to international organisations in the Joint Forest Sector Questionnaires (JQ1 and JQ2), in some cases giving more detail than in this release. These returns are published as Official Statistics on the FC website; provisional figures in May and final figures in September. The statistics are used by Eurostat Forestry Statistics, UNECE Timber Bulletins, and UN/FAO Forest Product Statistics and are published on the FAOSTAT database (www.fao.org/forestry/site/29420/en). Summary results from the FAOSTAT database are provided in the International Forestry chapter.

The definitions used in this publication are consistent with the international definitions, as given in Eurostat’s "Forestry in the EU and the World 2011":

The Department of Energy and Climate Change publishes an annual Digest of UK Energy Statistics (www.decc.gov.uk/en/content/cms/statistics/publications/dukes/dukes.aspx). Chapter 7 of this digest covers renewable sources of energy including wood. Figures for wood use in renewable energy statistics take into account wood from all sources (including processed wood, recycled wood and imports), not just UK-grown roundwood.

Release schedule

Provisional figures for 2012 will be released on 16 May 2013 in "UK Wood Production and Trade: 2012 provisional figures".

Final figures for 2012 will be released on 26 September 2013 in "Forestry Statistics 2013" and "Forestry Facts & Figures 2013".
