Transformation of hemiboreal ornithocenoses in modern forest management

The ornithocenoses of a sequence of forestry succession stages are studied in different types of hemiboreal forests of the Russian Plain, and the species of birds that determine each of the recognized stages is given. Statistical analysis showed that anthropogenic disturbances and natural succession processes played a significant role in the transformation of ornithocenoses, against a background of less influence from forestry activities (conifer plantations and their maintenance). Dispersion decomposition showed a high proportion of the combined effect of exogenous and endogenous factors, as well as their equivalent contribution to the formation of ornithocenoses, was demonstrated. Various types of logging are shown to facilitate shifts of natural succession of forest ornithocenoses to anthropodynamic successions characterized by specific subclimax stages.
