Background. Monitoring researches of spatial structure on constant squares allow to observe dynamics of changes of cenoz on the basis of the analysis and also to predict their development.
Materials and methods. Since 1993, monitoring of the floristic composition, population and spatial structures of woody and herbaceous vegetation has been carried out on a constant area of 1 ha.
Results. As a result of monitoring studies over a 25-year period, 3 maps (of approximately 10 years) of the mosaic pattern of vegetation cover were compiled on the territory of the Prisurskaya Dubrava nature monument.
Conclusions. The community has retained its inherent small-scale mosaic. However, there has been a significant increase in the proportion of small canopy breaks associated with the outbreak of a significant number of medium and old growth trees of normal and reduced vitality, which in the past have formed medium and large gap-mosaic. 

Key words
