Survey of Round Fencing Manufacturers

Introduction

The Survey of Round Fencing Manufacturers is an annual survey conducted by the Forestry Commission (in association with the Forest Service) of round fencing manufacturers (or mills) in the UK that are believed to consume UK-grown roundwood.

The survey, which previously covered mills in Great Britain only, was extended in 2004 to include those in Northern Ireland. Figures for Northern Ireland in earlier years have therefore been estimated, based on responses to the 2004 survey.

Figures are published as UK totals and by size of mill.

Longer time series, providing data on numbers of mills and on softwood consumption are available from the Timber Statistics web page at www.forestry.gov.uk/forestry/infd-7aql5b. The time series data feature breakdowns by size of mill and by country.

Data collected

The questionnaire (www.forestry.gov.uk/pdf/Fenqgb12.pdf/$FILE/Fenqgb12.pdf) used for the Survey of Round Fencing Manufacturers is issued to around 70 mills, to collect information on the consumption of UK-grown and (from 2006) imported roundwood. In 2008, the survey was extended to cover woodfuel quantities (sales to bioenergy, sales as firewood and internal use for heat/ energy) and total employment. In 2010, the survey was further extended to request data on production of round fencing and other products. A breakdown of the country of origin (England, Wales, Scotland, Northern Ireland) for UK-grown roundwood is also requested.

Response rates

In 2012, the questionnaire was issued to 68 mills, of which 26 responded, giving a response rate of 38%. These respondents accounted for an estimated 53% of roundwood purchased by softwood round fencing manufacturers.

Notes:

1. Response rates are calculated as the number of responses received divided by the number of forms issued.

2. Weighted response rates have been calculated from the 2008 survey onwards. They are an estimate of the proportion of total roundwood purchased by softwood round fencing manufacturers that is accounted for by respondents.

Methodology

Each year, figures for non respondents are estimated by rolling forward data from previous years for these mills.

Quality

Detailed information on the survey quality is available in the "Quality Report: Private Survey of Round Fencing Manufacturers" at www.forestry.gov.uk/pdf/qrfensur.pdf/$FILE/qrfensur.pdf.

Further quality information on FC Official Statistics is available at: www.forestry.gov.uk/forestry/infd-7zhk85

Revisions

Results from the Survey of Round Fencing Manufacturers may be revised between the provisional figures published in the First Release "UK Wood Production and Trade: provisional figures" and the final data published in "Forestry Facts & Figures" and "Forestry Statistics" to take account of late returns and the results of additional data quality checking procedures.

All figures are subject to revision annually, as information becomes available about mills opening or closing, or new information becomes available for previous non-respondents. Such revisions are generally quite small.

Figures for 2012 are final; provisional figures were previously released in "UK Wood Production and Trade: 2012 provisional figures".

Figures for 2012 and earlier years have not been revised from those in "UK Wood Production and Trade: 2012 provisional figures". Information on revisions made since "Forestry Statistics 2012" are provided in "UK Wood Production and Trade: 2012 provisional figures".

Release schedule

Provisional figures for 2013 will be released on 15 May 2014 in "UK Wood Production and Trade: 2013 provisional figures".

Final figures for 2013 will be released on 25 September 2014 in "Forestry Statistics 2014" and "Forestry Facts & Figures 2014".
