Validation of the stratification scheme used in site selection. Boxplots of measured values of nutrient levels (soil N g/m2), moisture levels (trimmed site mean % Volumetric Water Content (VWC)), and vegetation height (mean LIDAR canopy height (m)) for the a 90 natural sites of different fertility levels (infertile, fertile), moisture levels (dry, moist, wet), and successional stages (early (open), mid (herb/scrub), late (forest)) and b the 90 natural sites, 15 plantations, 15 fields and 10 perceived areas of high species richness (HighSpcRich)
