“…Phytoindication scales of Y. Didukh (Didukh, 2011;Didukh et al, 2021) are comparable to other environmental indicator values (Ellenberg) and reflect amplitude indices of the species characterized by the following dimensions: ecological indicator of soil humidity (Hd -23 grades), ecological indicator of variability of damping (fH -11 grades), ecological indicator of soil acidity (Rc -15 grades), ecological indicator of total salt regime (Sl -19 grades), ecological indicator of carbonate content (Ca -13 grades), ecological indicator of nitrogen content (Nt -11 grades), ecological indicator of soil aeration (Ae -15 grades), ecological indicator of thermoregime (Tm -17 grades), ecological indicator of humidity of microclimate (Om -23 grades), ecological indicator of continentality (Kn -17 grades), ecological indicator of cryoregime(Cr -15 grades) and ecological indicator of light in the community (Lc -9 grades).…”

The characteristics of shaded chasmophytic habitats on calcareous rocks in forest conditions are described, where the forest canopy primarily acts as a shading factor that determines microclimate, humidity and light levels. These communities can be found in deciduous forests of the Carpinion betuli, Fagion sylvaticae and Tilio-Acerion alliances, where they are confined to steep calcareous rock faces and cliffs. Syntaxonomically, these communities belong to the Polypodietea class (Ctenidio-Polypodietalia vulgaris order, Ctenidio-Polypodion vulgaris alliance) and to four informal communities: Isothecium alopecuroides-Polystichum braunii, Porella platyphylla-Asplenium ruta-muraria, Pseudanomodon attenuatus-Chrysosplenium alternifolium and Pedinophyllum interruptum-Polystichum aculeatum. We evaluated indices of environmental parameters according to the synphytoindication method using Didukh’s scales. An assessment of the threat impacts and indicators of sociological significance shows that the habitat belongs to a rare type (II class), and therefore requires specific conservation measures.

“…This principle is applied for developing spatial and timebased dependencies and scale-based dependency analysis methods [53]. Thus, for example, results of a research performed in the coastal woods of Poland allowed selection of eight uniform groups of rare species, reflecting the complexity and dynamics of shore zones [54].…”

Experience of Forest Ecological Classification in Assessment of Vegetation Dynamics

2022

Due to global climate change and increased forest transformation by humans, accounting for the dynamics of forest ecosystems is becoming a central problem in forestry. We reviewed the success of considering vegetation dynamics in the most influential ecological forest classifications in Russia, the European Union, and North America. Out of the variety of approaches to forest classification, only those that are widely used in forestry and forest inventory were selected. It was found that the system of diagnostic signs developed by genetic forest typology based on the time-stable characteristics of habitats as well as the developed concept of dynamic series of cenosis formation allows us to successfully take into account the dynamics of vegetation. While forest dynamics in European classifications is assessed at a theoretical level, it is also possible to assess forest dynamics in practice due to information obtained from EUNIS habitat classification. In ecological classifications in North America, the problem of vegetation dynamics is most fully solved with ecological site description (ESD), which includes potential vegetation and disturbance factors in the classification features. In habitat type classification (HTC) and biogeoclimatic ecosystem classification (BEC), vegetation dynamics is accounted based on testing the diagnostic species and other signs of potential vegetation for resistance to natural and anthropogenic disturbances. Understanding of vegetation–environment associations is fundamental in forming proper forest management methods and improving existing classification structures. We believe that this topic is relevant as part of the ongoing search for new solutions within all significant forest ecological classifications.

“…To assess the impact of climate change, point calculations of relevant indicators of 12 leading environmental factors were performed according to the scales and methods of Didukh (2021). Based on statistical processing of geobotanical data, the amplitude of their values for the corresponding syntaxon, average (X0), minimum (X0min) and maximum (X0max), as well as the correlation between their change for each of the factors, especially in relation to the temperature regime, were determined.…”

“…At the same time, we assumed that such climate changes act as a trigger mechanism that affects a change in edaphic properties of the soil, and such an indirect effect is much more significant than direct effects (Didukh et al, 2016). Based on the correlations between the changes in average annual temperatures, thermoregime of humidity of the climate, and continentality cryoregime, as well as indicators of edaphic factors (soil humidity and salt regime), corresponding calculations were carried out on the change of indicators at an increase in average annual temperatures by +1, +2, +2, 5, and +3 °C (Table 3) (Didukh, 2021). At an increase of +1 °C, the average thermoregime is already beyond the amplitude of the modern existence of these communities, and with changes in temperature conditions, these groups fall into the risk zone of reduction.…”

This article deals with phytosociological and ecological requirements of the vulnerable species Festuca pallens in Ukraine. Based on the analysis of 51 relevés, we have recognized the occurrence of Festuca pallens in three associations within the Festuco-Brometea class. Some communities where Festuca pallens occurs have transitional stages of succession to forest edge vegetation according to the expert system classification. In addition, we evaluated the ecological differences among occupied habitats using Didukh’s phytoindication scales and concluded that the most important ecological factors are soil humidity, nitrogen content, soil aeration, salt regime, carbonate content, thermoregime, and climate continentality. Finally, we evaluated the threats to the existence of these communities with the presence of Festuca pallens, taking into account climate change and other impacts of anthropogenic activities (illegal mining, recreation, afforestation).
