Table 4 Estimates of carbon stock changes between 2002 and 2007 and 2009–2012 for all forests, and for tall forest and regenerating forest separately within the pre-1990 natural forest. Plus-or-minus values are estimated 95% confidence intervals calculated using two methods; the first method is based solely on sampling variation between plots (CIs); and the second method combines the effects of sampling variation and prediction uncertainty (CIs&p)
