Figure 4.4 Annualised rates of stand-level basal-area(BA) growth, basal-area mortality, stem recruitment and stem mortality from plots with two consecutive census intervals, each giving the mean from 50 plots with 95% confidence intervals. Paired t-tests show that all of the increases are significant. The average mid-year of the first and second censuses was 1989 and 1996, respectively(from Lewis et al. 2004b)
