Annual figures for coniferous standing sales from Forestry Commission owned woodland broken down by size category, and for Forestry Commission sales of softwood logs, are obtained from administrative records held by the Forestry Commission.  The figures are obtained twice yearly, covering the year to 31 March and the year to 30 September for standing sales and the six month period to 31 March and to 30 September for logs.

The GDP market prices deflator (published quarterly by the Office for National Statistics) is used to convert the figures to real prices (September 1996 base).

The coniferous standing sales prices are converted to a Laspeyres index, which allows the figures to be compared over time on the basis of a constant (September 1996) size mix.

The coniferous standing sales and softwood log indices are published twice yearly, in May and November, in the First Release Timber Price Indices.  This publication includes further detail on how the indices are compiled.

Estimates of financial returns from commercial Sitka spruce plantations are compiled and published by Investment Property Databank Limited (IPD).  The returns include changes in the value of forestry estates, as well as timber price changes.

Statistics on gross value added (GVA) are obtained from the Annual Business Inquiry (Office for National Statistics), an annual survey of UK businesses.  The Annual Business Inquiry uses the Standard Industrial Classification (SIC) to classify businesses to industries according to their main activity.

Information about government expenditure on forestry is obtained from administrative records held by the Forestry Commission.  Data are published annually in the Annual Report & Accounts produced by National Offices.

Data on grant expenditure are obtained from administrative records for woodland grant schemes across GB.
