General regularity of biodiversity changing of birds population in technogenic landscapes in south part of Baikal region
The authors examine the changes of birds' variety of the technogenic landscapes in south part of Baikal region (Tulunskii, Kujtunskii, Ziminskii, Zalarinskii, Chermchovskii, Usolskii, Irkutskii, Olchonskii, Sludanskii fields of Irkutsk region). The highest meaning of species abundance and diversity are on the coal ash dumps with grass and bushes. High meaning of birds' density is observed on the coal ash dumps without plants, with homogenous conditions of environment. It is regarded groups of sites with different variants of transformation. It is followed time sequence of changing from native areas, changed, than abandoned or recultivated.
