Abstract
The regularities of the typical stages of self-recovery (regeneration) of the subpopulation structure of Soldanella hungarica Simonk. after rigid local destructions were generalized relying on the results of multi-year (1974–2011) monitoring on permanent test grounds of the Institute of Carpathian Ecology, NAS of Ukraine, situated near the upper boundary of spruce forest in the Carpathian mountains. It was revealed that under the experimental conditions the point impacts of this kind do not cause general destabilization of population processes. However, they initiate behavioral reactions aimed at the mobilization of population reserve of S. hungarica at closely located territories. Unequal roles of individual and group effects in this phenomenon were revealed. The conclusion concerning the determining importance of the vitality composition for the results of the local regeneration of S. hungarica population was made. It was stated that self-recovery of the structure of S. hungarica on experimental grounds is a long-standing process requiring several ten years.
