“…(Boltižiar 2022). Snow avalanches are a special phenomenon (Rączkowska et al 2016a;Boltižiar et al 2016). The morphodynamic phenomena of the highmountain landscape are characterized by high dynamics and frequency of geomorphic processes, extreme disturbance effects on the landscape, which are remarkably reflected also in the changes of the vegetation patterns.…”

The geomorphic processes in high-mountain environments are crucial and often limiting factors of vegetation development. Studies based on the long-term field monitoring are still scarce, however, thus limiting our understandng to vegetation dynamics and the knowledge needed for effective conservation management. In this paper we interpret results of a 20 years long observation considering the relationship between alpine vegetation and intensity of geomorphic processes in the territory of seven permanent plots in the Belianske Tatra Mts. (Slovakia, Central Europe). In principle, these sites represent a “battle field” for ongoing geomorphic processes and vegetation. They are either gradually occupied by initial stages of ecological succession of vegetation or were occupied in the past with the vegetation being more or less destructed. The field research was combined with data collection for standard phytosociological relèves. Spatial distribution of particular tussocks or individuals on each field was drawn in detail. We observed the share of species and their spatial arrangement in relation to the control sites with uncovered substrate. Special attention was paid to measuring the intensity of geomorphic processes using various methods and carried out three times a year. The CANOCO software was used for quantitative evaluation of the phytosociological relèves data. We applied indirect gradient analysis of principal components (PCA) to find out the variability of vegetation and sites, and the direct gradient analysis (RDA) to explain the diversity of species ad the habitat characteristicsThe geomorphic processes affecting the extreme high-mountain environment were evaluated as the most crucial elements that determine the spatial distribution of vegetation, its particular species or overall nature of coppice fragmentation. The relief and mainly its spatial geomorphic attributes are therefore relevant phenomena of landscape that enable scientists to understand, for example the scale and hierarchy of vegetation arrangement. The relationship of vegetation and the intensity of geomorphic processes can be only considered and generalized on the basis of longtermed research.

“…Due to the higher degree of results relevance, M. Žiak [50] was able to develop the concept of the avalanche geographical information system, representing the updated digital version of the avalanche cadastre, by applying geo-information systems and remote sensing methods. Over the last decade, a large number of articles have been published which have made significant contributions to a better understanding of the processes associated with avalanche issues [51][52][53][54][55][56][57].…”

The aim of this work is a comprehensive assessment of the avalanche risk within the Kráľova hoľa area in the Low Tatra Mountains in Slovakia by the modeling of trigger areas, and the simulation of avalanche movements and their maximum impact using GIS and the RAMMS simulation model. Within the environment of geographic information systems, we created a layer of trigger areas using a digital elevation model and a vector layer of a land cover as input data. This layer was added together with the digital elevation model to the RAMMS simulation model, where cartographic outputs were created, focusing on snow cover height, avalanche flow speed, and pressure exerted by a falling avalanche. Based on these documents, we were able to develop an updated map of the avalanche cadastre of the examined area. In the given territory, we mapped a range of trigger areas within an area of 2.6 km2 and the total range of avalanche run-outs within 14 interconnected areas. Of all the high mountains in Slovakia endangered by avalanches, this is the lowest range. The results are a suitable basis for the proper management and optimal use of the territory, which is part of Low Tatras National Park.

“…Besides, the first geomorphological research and lake mapping in the High Tatras highlighted these lake infilling processes (Rehman 1892, Schaffer 1930, Szaflarski 1933 and they were also thoroughly covered in the first comprehensive relief studies and detailed geomorphological mapping of both Slovak and Polish mountain aspects. Authors have also provided indirect evidence of decreased lake volume and water surface area caused by the High Tatras morphodynamic processes (Lukniš 1973, Hreško and Boltižiar 2001, Hreško et al 2003, Gregor 2005, Gregor and Pacl 2005, Hreško et al 2008, Kapusta et al 2010, Boltižiar et al 2016, Gallik and Bolešová 2016, Kłapyta et al 2016.…”

This paper assesses the shrinkage of glacial lakes in the High Tatras by analysing the series of historical and actual orthophotomaps from 1949 to 2018. The shoreline dynamics during this period were established by detailed retrospective remote sensing, and the decrease in the former surface of the water was caused by intensive interaction between morphodynamic processes and the lake basins. Herein, we have identified 38 tarns with an assumed decline in the area. This assumption was based on a comparison of initial visual analysis of the historical aerial photographs and the current orthophotomaps which capture all High Tatras tarns. We selected ten tarns with the largest or most representative changes and performed detailed cartographic analysis on them. We also attempted this analysis over shorter periods whenever possible and herein we established from 2.5 to 32.2% decrease in lake water surface area during the monitored period. This decrease in shallow lake basins was accompanied by the presence of accumulated debris flows, fine fraction fluvial-proluvial deposits, and vegetation. The shallow glacial lake basins are sensitive indicators of irreversible changes in their catchment areas and this study, therefore, highlights the effectiveness of combining detailed orthophotomaps and historical aerial photos and GIS tools in researching glacial lakes shoreline dynamics in the alpine landscape. Retrospective shoreline analysis facilitates the assessment of the effects of morphodynamic processes on the development of tarns from the postglacial period until today.
