The methodology and outputs relevant to a particular topic are reviewed regularly to ensure that they are fit for purpose. The topics include wood production, imports and exports, woodland area, timber prices, environment and climate change, recreation, and FC administrative data. One topic is reviewed every year on a rotating basis.
There is a parallel process for survey reviews.
More in-depth reviews, to address specific issues, are undertaken on an ad hoc basis. These may consider:
- Potential problem areas;
- New or changed concepts, definitions and classifications;
- New or changed data sources.
- Potential method improvements
- New or changed data requirements;
For substantial methodological changes, we will produce a paper outlining the changes to be made and the effects of these changes. This paper will be released on our website before the release of any statistics based on the new methods.
Our revisions policy sets out how we deal with revisions and errors to our statistics.
Further details on specific methodology and output reviews are provided below.

Annual Woodland Area Estimates 2012
The methodology used to estimate the area of GB woodland was refined in 2012. Further details can be found in the Methodology Note: Annual Woodland Area Estimates.
Softwood Removals from Non-FC/FS woodland 2012
A review of the methodology used to estimate the quantity of UK softwood removals** from woodland that is not owned or managed by the Forestry Commission (in Great Britain) or the Forest Service (in Northern Ireland) was undertaken in 2011-2012. The paper Methodology Review of Softwood Removals from Non-FC/ FS Woodland presents the results from this review and the implications of the proposed change in methodology.
** Softwood removals refers to the harvesting of roundwood (logs and small branches) from coniferous trees.
Price Index Review 2008
A review of the methodology used to calculate the Coniferous Standing Sales Price Index (CSSPI) was undertaken in 2007-2008. The paper Methodology for the Coniferous Standing Sales Price Index explains the rationale for the change in how the index is calculated. The new methodology was first implemented in the November 2008 publication of Timber Price Indices.
