The total carbon stock in UK forests has increased from 1990 to 2005 and is projected to continue to increase to 2010. The carbon in forest soils (depth up to 1 metre) accounts for most (around 80%) of total forest carbon. Most of the increase in soil carbon is existing soil carbon in areas afforested between these dates, not additional carbon sequestered.

1. Excludes carbon stock on other wooded land (3 million tonnes soil carbon and 0 million tonnes other carbon), which is also reported in the MCPFE indicator.
2. The standard factors used to estimate carbon in below-ground biomass are now believed to be too low. A review of recent studies has indicated that the totals could be around twice the level shown.
