As an Accredited Official Statistics output, this publication concentrates on topics for which the data meet Accredited Official Statistics quality standards. However, some topics outside the scope of Accredited Official Statistics are included, to give a more rounded picture; any such tables are footnoted as “outside the scope of Accredited Official Statistics”. This means that they have not been subject to Accredited Official Statistics quality assurance procedures but does not necessarily imply that they are of poorer quality. This edition of Forestry Statistics includes the following tables and charts that are outside the scope of Accredited Official Statistics:

• Table 1.2: Woodland area in the UK (time series);
• Tables 1.6 to 1.11, figures 1.3a and 1.4b: National Forest Inventory;
• Table 1.15: Felling licences;
• Tables 1.16a and 1.16b: Statutory Plant Health Notices;
• Table 1.17: Canopy Cover in England.
• Table 2.4a: Softwood availability forecasts;
• Table 2.4b: Hardwood availability forecasts;
• Table 2.30: Recycled wood used for woodfuel;
• Tables 4.1 to 4.3, Figure 4.1: Carbon;
• Tables 5.1a and 5.1b: Woodland types and habitats;
• Table 5.4 and Figure 5.4: Tree health;
