Aboveground Biomass Models for Indigenous Tree Species in the Dry Afromontane Forest, Central Ethiopia

Figure 2

Scatter plot matrices showing correlation coefficients between tree variables and significance levels for (a) E. capensis, (b) N. congesta, and (c) R. ruspolii in Menagesha Suba dry afromontane forest, central highlands of Ethiopia. On the top of the diagonal, the value of the correlation (Corr.) is shown, plus the significance level of the -values, which are indicated by asterisks, , <0.001; , <0.01; and , <0.05. The abbreviations AGB represent above ground biomass, TH = tree total height, DBH is diameter at breast height, DSH is diameter at stump height, and WD = wood density.
