Table 3 Mean C and N contents (% of dry biomass) with standard deviation for six plant groups based on 63 samples per plant group, i.e. 7 samples in 9 strata of elevation class (< 601, 601–1200, > 1200 m) and focal region (North-East, North-West, South)

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