Description

 Due to long comparative studies, it has been established that in protected areas demotion successions lasting more than 30-40 years cause a significant threat to numerous rare species and phytocenoses due to colonization by shrubs and violet herbaceous species. These adverse processes are exacerbated by climate change. The smallest changes were made by the tripartite cells, blueberries, rhododendrons and sesler. At the same time, the position of the dominant in the recumbent and bent pads significantly decreased. Leaf beds are decayed and replaced by other phytocenoses. In the subalpine zone, cereal meadow coenoses are replaced by secondary-derived blueberry groups and competitive species. As a result of the reduction in the duration of snow occurring in chionophilic settlements, gradual succession changes occur. The greatest impact on the vitality of individuals and populations is caused by changes in pricing positions between different types of life forms and strategies. Pseudo-rejuvenation of populations is inherent not only under the influence of anthropogenic factors, but also in adverse natural changes in the environment or negative endogenous processes. For rare species of Carpathian plants, examples of adverse natural factors are, first of all, modern climatic changes and demotion successions. In Achillea lingulata populations, opposite dynamic trends are observed in different (optimal or pessimistic) phytocenotic conditions: positive in low-grassland highland grasslands and negative in abandoned pastures. These trends are related to the succession of vegetation caused by the decline of traditional land use (primarily grazing) and climate change. The determinant of the negative dynamics or, conversely, the stability of populations of a number of rare Carpathian species is the presence of loci that allow for effective self-maintenance. This is often a limiting factor in the size of their populations.
