At plots I and II, the share of mycorrhizal spe-
cies on a measure of self-organized vegetation
increased approximately twice from 25-38 % in
1978 to 61-70 % in 1990-2006. The difference
between these plots consists in the following
aspects: On plot I in the process of vegetation
development, the share of optional mycorrhizal
species mainly decreased (from 50 % in 1978 to
21-22 % in 1990-2006). On plot III, the observa-

tion showed that the plants' proportions of differ-
ent mycorrhizal status for the 30-year-old period
of observation did not change despite essential
change of the general fl oristic structure of plants
(Kuprijanov and Manakov 2008 ).
The similarity of the highlights of the tempo-
ral dynamics of participation of different mycot-
rophy on different parts of dumping allows to
combine data and analyze them together. A pro-
