The subjects of this study were the plant succession of the regrassed and spontaneously revegetated fields in the Bohemian Forest foothills and the effect of grass cutting management on vegetation changes in time and some of the important soil microbial characteristics. The main aims of this study were to assess i) the phytocoenose differences between the re-grassed and spontaneously revegetated fields, ii) the effect of abandoned field surroundings on the field grassing, iii) the possible correlations between the successional age of fields and characteristics of meadow plant species. The data for the landscape view were collected during the season 2008 and were analyzed by ordination methods (DCA, CCA) and by the ANCOVA. The second data for the detailed view were collected during three seasons (2006-2008) from ten experimental squares and were analyzed by the ordination method (RDA) and the methods Repeated Measures ANOVA and One Way ANOVA. The significant difference between regrassed and naturally revegetated fields was not found. The effect of surrounding was important, while most of the plant species (86% in average) occurring in the surroundings were also found on the studied fields. The field age was positively correlated with particular characteristics of presented meadow plant species. Although the effect of grass cutting on the phytocoenose was not significant, the effect on the microbial biomas was significant in the mineralization rate of soil organic mater.
