Survey of Round Fencing Manufacturers

Background

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.

Data collected

The questionnaire used for the Survey of Round Fencing Manufacturers is issued to around 80 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 2010, the questionnaire was issued to 79 mills, of which 34 responded, giving a response rate of 43%.  These respondents accounted for an estimated 46% of roundwood purchased by softwood round fencing manufacturers.

Methodology

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

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 and 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.

Reporting

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.  The time series data feature breakdowns by size of mill and by country.
