ABSTRACT
The presented work shows a method of evaluating the changes of territorial sozofloristic value which illustrates the effects of anthropogenic pressure on threatened and rare flora of a given area. As a result, a distribution map of the changes of the flora is shown, aiming to support conservation activities within Opole voivodship, e.g. the flora conservation strategy. The territorial sozofloristic value has been determined in two stages. In the first stage, the species sozofloristic value for a selected group of 302 plant species has been evaluated on the basis of 14 criteria. These were plants considered rare, threatened or protected within the province borders, so-called sozophytes. Then, species sozofloristic values have adequately been summed up on the readily prepared cartogram consisting of 2298 basic squares, thus receiving the territorial distribution of floristic richness of the region. Next, the comparison of the sozofloristic value between two periods, 1806-1944 and 1945-2001 were done. The analysis of characteristic features and reasons of the received distribution has been undertaken, with the particular taking into consideration the territories of the highest changes of the sozofloristic value. The possibilities to use these analyses in regional flora conservation have been presented.
