Table 2 Ecological ranges (from 5 percentile, p5, to 95 percentile, p95) of the abiotic soil parameters for the abiotic response per ecosystem. Given are the median values of the p5 and p95 of the pH-H2O, \( {\mathrm{NO}}_3^{-} \) content (in mg NO3 kg−1) and mean spring water level (MSW, cm below surface) for the selected species
