Table 5 Coefficients and standard error of standard linear regression model (Eq. 2) between total above-ground biomass including woody parts of shrubs and cover class and elevation on subplots. For each cover class mean (±SD) observed and predicted biomass is presented; see Table 1 for sample size

From: Extending harmonized national forest inventory herb layer vegetation cover observations to derive comprehensive biomass estimates
