Description
Attempts were made to determine whether the spatial distribution of the plant species composing vegetation of a semi-natural grassland is heterogeneous, using negative hypergeometric series (NHG) and Taylor’s power law (TPL). The occurrence of each species was observed, in an area of the grasslands, using 100 quadrats with a size of 50 cm x 50 cm, each of which was divided into 4 small quadrats with an area of 25 cm x 25 cm. For all species dominating in the grassland, good fits to the NHG and TPL were obtained. Species which grow stolons, rhizomes and tillers for propagation such as Potentilla freyniana and Hydrocotyle ramiflora, exhibited a highly heterogeneous spatial pattern.
