Research Abstract

Spatial heterogeneity of phytomass in the semi-natural grassland was higher in a grazed condition than in both a condition with spatially uniform defoliation and a condition without defoliation. Grazing inhibited spatially homogeneous domination of a few tall grasses and induced to occur spatially heterogeneous floristic compositions. Grazing animals used spatially heterogeneously the vegetation, and slight spatial biases of soil nutrients were caused. Nutritive values of available herbage had less heterogeneous spatially than both the phytomass and the floristic composition.
