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.
Woodland Carbon Code Statistics Review 2015
In 2015, Woodland Carbon Code Statistics were reviewed. The findings and action plan can be found in this report.
Woodland Area, Planting and Restocking Review 2014
In 2014, woodland area, planting and restocking were reviewed. The findings and action plan can be found in this report.
UK Wood Imports & Exports Review 2013 & Methodology Note
In 2013, UK wood imports & exports were reviewed. The findings and action plan can be found in this report.
Methodology note: UK wood imports and exports sets out the data analysis methods used to produce annual estimates of UK wood imports and exports.
UK Wood Production Review 2012 & Methodology Note
In 2012, UK wood production was reviewed. The findings and action plan can be found in this report.
Methodology note: UK wood production sets out the data analysis methods used to produce annual estimates of UK wood production.
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.
Forestry Statistics Review 2002
The main Forestry Commission statistical outputs were brought into the scope of National Statistics in August 2001. As part of our commitment to ensuring that our statistics meet quality standards, we carried out a National Statistics Quality Review of forestry statistics in 2002. The review assessed how well the Forestry Commission's National Statistics outputs meet users' needs, as well as the quality of the outputs, from data collection to publication. In addition, the user demand and feasibility of producing separate forestry statistics for Scotland, Wales and England was assessed.
The Project Initiation Document provides details on the scope of the review and organisational arrangements.
The final report of the review, which includes a number of recommendations for improvement, was published on 13 December 2002. We have also prepared an implementation plan, to show the action we propose to take on each of the recommendations. A final report on implementation plan progress was published in 2007.
We would like to record our thanks to all those who participated in the review.
Consultation on UK Indicators of Sustainable Forestry 2001-2002
The UK Indicators of Sustainable Forestry were developed through 2 rounds of consultation in 2001 and 2002. See the consultation process page for further details.
