The role of β-diversity of plant communities as a factor in its phytoindication significance has been revealed. We studied the continuously flooded semi-light elm-oakery with blackberry De'' 2-3 in the river Dnipro floodplain within the nature reserve of "Dnipro-Orelsky". Plant community relates to suballiance Ulmenion minoris Oberdorfer 1953 union Alnion incanae Pawlowski 1928 Null-order alfa diversity is 8.74 (95% confidence interval 8,62–8,91). Null-order beta-diversity is at the level of 6,86 (6,44-7,17), and gamma diversity is at the level of 60 (56,01–63,01). Environmental factors identified using phytoindication approach have been found to be correlated with each other, resulting in the formation of their regular complexes. The complex nature of the aggregate environmental factors that describes a multidimensional factor-1, can be identified as the result of forest pertinentia (according Visotsky). Less important multidimensional factors in their mathematical properties are close to ordinary phytoindicator factors. Structuring of β-diversity indicates that the plant species differ in their informational value to indicate a variety of environmental factors. Established plants clusters represent a plurality of kinds, characterized by the highest information value to indicate certain factors. Indicator ability of the vegetation to display the action of environmental factors spatially heterogeneous. In condition when the neutral or random factors prevail over phytoindicator useful information, there is disinformation on the relevant factors. The disinformation zones established for all multi-dimensional factors and they have a specific spatial location.
