Forestry Statistics 2013 - Woodland Areas and Planting

National Forest Inventory

previous | next  

This section contains interim results from the National Forest Inventory (NFI). The statistics are based on field survey data combined with information from the NFI woodland map, which is a spatial representation of woodland areas in Great Britain.

The first cycle of the NFI field survey began in 2010 and will be completed in 2015. Therefore full field survey results from the NFI are not yet available. The NFI report "Standing Timber Volume for Coniferous Trees in Britain", released in April 2012, provides interim results on the area and standing volume of coniferous trees, including breakdowns by species and age class, based on the sample squares surveyed up to January 2012. Equivalent figures for broadleaved species are available in "NFI preliminary estimates of quantities of broadleaved species in British woodlands, with special focus on ash", released in December 2012. Both reports are available at www.forestry.gov.uk/forestry/infd-8tel28.

The figures presented in Tables 1.6 to 1.9 (and Figures 1.3, 1.4a and 1.4b) relate to stocked areas. These differ from the woodland areas presented in earlier tables, as stocked areas exclude felled areas and (for non-FC land) areas of integral open space. All estimates in these tables and figures are reported to a reference date of 31 March 2011.

The figures on coniferous growing stock presented in Table 1.10 form the basis for the Forestry Commission's softwood availability forecasts (see Table 2.4).
