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 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 100 mills, to collect information on the consumption of UK and (from 2006) imported roundwood. A breakdown of the country of origin (England, Scotland, Wales, Northern Ireland) for UK roundwood is also requested.
Response rates
In 2007, the questionnaire was issued to 103 mills, of which 67 responded, giving a response rate of 65%.

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' 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. Data for individual countries can be produced, subject to confidentiality constraints.
