Abstract—The overgrowing of meadow-bog communities by shrubs and trees (age 5–40 years, crown closure
0.4–0.9) leads to a decrease in incident illumination. As a consequence, juvenile and generative plants disappear
from D. incarnata population loci, their average ecological density decreases, and the loci enter the state of
regression. The digging activity of wild boars disrupts phytocenotically closed groups of longirhizomatous
herbs, thereby creating favorable conditions for seed reproduction of D. incarnata. The species begins to form
population loci with a complete ontogenetic spectrum and high ecological density, eventually restoring the nor-
mal (definitive) population structure.
