Vegetation classification of the Voronezhsky Nature Reserve

E. A. Starodubtseva, L. G. Khanina



Voronezhsky nature reserve is situated in the forest-steppe zone of European Russia, on the border between Lipetsk and Voronezh regions. The reserve was estab­lished in 1923; the total area of the reserve is 31 053 ha. We have created the vegetation classification system for the reserve on basis of 1058 phytocoenotic relevés processing. Phytocoenotic relevés have been collected since 1929 by different generations of researchers. All relevés were included into the data processing. Five forest vegetation formations and one herbaceous formation were described. According to the reserve’s forest inventory from 1991, Pinussylvestris formation occupies 32.3% of the reserve area, broad-leaved forest (oak forest) formation — 29.3, Populus tremula formation — 19.3, birch forest formation — 5.7, and Alnus glutinosa formation — 5.2 correspondingly. Her­baceous formation covers 3 % of the area in dry, moderate moistened and moist soils, and swamps occupy 2.5 % of the reserve area (they are not described here). Within the bounds of the vegetation formations, we have distinguished the vegetation association groups on the basis of ground vegetation functional group composition and ordination (DCA) technique. 8 functional species groups (ecologic-coenotic species groups) were used for the classification. The ecologic-coenotic species groups were as follows: 1) nemoral, 2) boreal, 3) nitrophilous, 4) pine-forest, 5) meadow-forest edge, 6) steppe, 7) oligotrophic, and 8) water-swamp. Totally we have described 23 vegetation asso­ciation groups united into the 9 ecologic-coenotic types of vegetation cover. 4 vegetation association groups were described for the herbaceous formation. We described in detail vegetation association groups inclu­ding species, structural diversity and the ecological position calculated by Tsyganov’s ecological species values. We also discuss the group’s history and the succession status. Finally, we have compared the proposed vegetation classification system for the re­serve with some other classification systems.
