Abstract (eng)
Since the 1960ies a strong decline of the populations of the European hare has been recorded. To initiate management measures, it is necessary to know their habitat characteristics. For this reason the floristic composition, the species richness and the vegetation structure (vegetation height and density) of five hare home-ranges are to be studied in the following master thesis. Subsequently, the latter two are to be correlated with the size of the home-ranges. Concerning the floristic composition, all home-ranges and landscape elements are relatively similar. There are just small differences, by which the elements are distinguishable from each other. The sizes of the home-ranges are between 14 ha and 40 ha. The species richness within the home-ranges ranks between 63 and 125 plant species. The smallest individual has a height of 1.1 cm, the tallest plant measures 159.0 cm. The vegetation density ranges between 0 % (completely permeable) and 100 % (not permeable). Considering the vegetation height and density, one will find a strong variability. There is no correlation between vegetation density and the size of home-ranges. But the home-ranges are greater, the greater the variability of the vegetation height is. As for species richness, there is a link between the mean number of species within the herb layer and the home-range size. That means if the mean species richness in this layer is small, the related home-range is small, too.
