She includes botanic data from literature sources as of the year 1800 until the presence as well as extensive data from field studies conducted between 1984 and 2004. Thus the flora reflects the floral status quo of a region in eastern Germany in the time shortly before and after the reunification of both German states in a very special way, as well as the economic changes linked to this. Thus, increasing effects of biological globalization are also evident in a shift of the floral composition to the advantage of many exotic species. In the introduction, the spatial conditions of the natural conditions of the areas studied are described, and the methods of botanical surveying explained. Subsequently, all of the 1329 plant species found in the areas are presented. Each individual species is discussed briefly. In the descriptions, general information on distribution, plant community, and local site conditions as well as special data on the frequency, endangerment, status, level of establishment, occurrence in habitats with different proximity to nature, sites where the plant species are found as well as the regional blossoming times are offered. For 272 of these species, the sites where the plant populations were found are presented in distribution maps in relation to the current biotope structure. An analysis of the complete species diversity is also included. In this section, the change of species diversity from 1800 to 2004, the evaluation of plant occurrence on the locations with different proximity to nature, the plant-geographical situation of the area as well as the specific endangerment of the species are given special attention. In the literature section, floral literature relevant to the area is compiled.
