In early June, the 24th General Meeting of the EGF took place in one of the oldest agricultural centers in Eastern Europe. The Congress Centre of the Lublin University of Natural Resources in Poland has hosted more than 300 scientists from 41 countries. During the event, the participants were offered tours, seminars, presentation of oral and poster presentations, and workshops for young scientists. The business meetings of the Presidium were dedicated to making decisions on a European scale.

Kozhevnikov V. I., Grechushkina-Sukhorukova L. A., Peschanskaya E. V., Isaenko T. N. Experience of restoring the meadow-steppe coenosis in the Stavropol Botanical Garden by turf planting

13

УДК: УДК 581.9 (470.63)

Results of comparative analysis of 40 years of meadowsteppe coenosis restored by turf planting and initial donor coenosis are presented. In the course of autogenous succession in experimental community the positions of the initial dominants weakened. Th e species composition was 65- 97 species per 100 m², 15 endangered species were saved, biological productivity reached 3.98-6.91 t/ha. Th e results of an entomological research are also presented.

Keywords: coenosis, meadow steppe, turf, succession, dominance, species сompositions (richness), biological productivity, endangered species, entomological research
