Studies of the ecological behavior of vascular plants of the ground-cover vegetation of forests. II. Species that are concentrated on moderately dry to moderately moist soils

The ecological behavior of 62 vascular plant species of the ground-cover ve getation of forests was investigated with regard to soil humidity and soil acidity. The study concentrated on soils from moderately dry to moderately moist. Most species show a wide amplitude with regard to the moisture facto r. Partly they are more likely to be found at more dry sites and partly at sites with sufficient water supply. Some of the species can even be found o n wet soils. The amplitude of most species is also wide with regard to acid ity. The mainly applies to species which inhabit slightly acidic to moderat ely acidic sites. Several good indicator plants can be found for highly aci dic to acidic soils. Only few species, however, can be characterised as lim estone indicators.
