Landsliding as a Limit to Possible Territorial Development in the Kysuce Region

Abstract

The growing development of settlements in mountainous areas and their sustainable development constantly requires new approaches to assess the land in terms of occurrence of landslides. The flysch zone, where the monitored area is located, is one of the most landslide prone areas in Slovakia. Landslides respond sensitively to the quality of the individual factors that form the landscape and to the change of natural conditions. Their occurrence is a geo-barrier that reduces or totally prevents the use of natural environment and negatively affects the life of population and territorial development. The reason for the increased hazard of landslides is not only demographic pressure on territories, but also its poor management. Consistent spatial planning addresses not only the spatial layout but also the functional use of the territory. Landslides represent one of the limits of land use. This study is based on the assessment of landsliding as a limit to possible territorial development. The input parameters for the assessment were elements of the current landscape structure (built up structure, forest stands, transitional woodland-shrubs, traditional agricultural land, permanent grasslands and arable land) and occurring landslides (active, potential and stabilized). On most of the determined elements of the landscape, landslides occur on about a quarter of their area. They have a smaller share only in areas of mixed forests, built up areas and have the smallest share on arable land. Potential landslides have the largest proportion on all landscape elements. They occupy the largest areas on coniferous forests (1578.93 ha) and on permanent grasslands (741.33 ha). By evaluating the overall endangerment of the area by landslides according to the degree of threat, we found that the greatest threat of landslides is in the Skalité and Svrčinovec cadastral areas, the smallest threat is in the Čadca cadastral area. In addition to the danger of landsliding in the individual elements of the landscape, we have also set limits for its development. Spatial planning limits have been divided into two categories according to the sectors they affect the most: limiting the development of an area assigned for residential building, or restricting the development of an area designed for agricultural and forestry purposes.

Abandonment of agricultural land in central Poland and its ecological role

Abstract

Majchrowska A.: Abandonment of agricultural land in central Poland and its ecological role. Ekologia (Bratislava), Vol. 32, No. 3, p. 320-327, 2013. The intent of this paper is to give an overview of the ongoing study of farmland abandonment in central Poland. The goal of this project, initiated in 2011, is to provide field-verified information: 1. What is the spatial distribution of abandoned agricultural land in central Poland? How is it related to biophysical features of the study area? 2. What are botanical characteristics of spontaneous vegetation succession in the abandoned agricultural lands? What are their environmental determinants? 3. How do the abandoned lands correspond to existing protected areas? How could they be used to strengthen the ecological landscape structure of central Poland? The paper summarises the general study approach, discusses some methodological difficulties, presents preliminary findings and formulates the expected results.

THE EVALUATION OF ECOLOGICAL FACTOR S AFFECTING ENVIRONMENTAL FUNCTION S OF THE SOIL S IN AREA OF TRADITIONAL AGRARIAN STRUCTURE S

Abstract

Krnačova Z., Hreško J., Kanka R., Boltižiar M.: The evaluation of ecological factors affecting environmental functions of the soils in area of traditional agrarian structure. Ekologia (Bratislava),Vol. 32, No. 2, p. 248-261, 2013. Cultural landscape can be seen as a result of hundred years of founding and sensitive cultivation of landscape structures respecting natural conditions. Specific geomorphological, climatic as well as social conditions enabled the conservation of original agrarian landscape structures mainly in the marginal regions of Slovakia. They are created by mosaic structures of extensively used small-scale landscape elements of permanent agricultural and arable land. An example of traditional agrarian way of using is foothill meadow-grazing landscape of the village Liptovska Teplička. By using the traditional extensive maintenance of the agricultural landscape, optimal environmental characteristics of soils were preserved. These were modified to some extent by the way of using and management. The submitted contribution is focused on the following:

• Indication of environmental characteristics of soils

• Quantification of the influence of chosen ecological factors on these environmental functions Seven research localities representing main types of the traditional landscape maintenance were chosen for needs of the research of soil and environmental conditions in a relation with the way of using the land and management. In given localities, we chose 21 sampling sites for secondary landscape structure (according to the legend of project Corine Land Cover, 2000), geological, soil, physical, biochemical and chemical conditions evaluation. Environmental functions indication was assessed in the following way: by assigning an amount of organic carbon (Cox) in a standard way (Fiala et al., 1999) for production functions, by assigning a ratio of granular fractions (pipetting method according to Novak) for retention functions. Buffering functions were evaluated potentiometrically by assigning an active soil reaction of pH (H2O) and exchange reaction of pH (KCl) in a soil. Highest values of Cox in the Ap horizon (7.67-6.62%), as well as pH of the soil environment (pH/KCl 7.26-7.21, pH/H2O 7.69-7.68) were assigned to anthrosolic and cultisolic rendzinas of extensively used grasslands. On the contrary, the lowest monitored values of organic matter Cox (2.51-2.53%), as well as pH of the soil environment (pH/KCl 4.81-5.21) (pH/ H2O 5.21-6.19) were indicated for soil subtypes anthrosols of the large fields and lithosol of theextensively used grasslands on non-carbonate substrates. Most favourable production and buffering soil properties were preserved in rendzinas on the carbonate substrates and extensively used meadows. Similarly, this type of soil on limestone used in a form of extensive meadows preserved also the most favourable retention functions according to the stated ratio of granularity fractions. Quantification of the influence of chosen ecological factors on environmental functions was performed using multivariate statistical methods, specifically principal component analysis (PCA). PCA is an indirect gradient analysis using the linear correlation of data, with a biplot as an output. Closeness of points in ordination graph represents their similarity of composition. The CANOCO (Ter Braak, Šmilauer, 2002) software was used to perform the analysis and to create the graph.

Woody Plants Affected by Ungulates in Winter Period, Impacts and Bark Renewal

Abstract

Due to biotope fragmentation and changes in landscape structure, opportunities for forest animals to migrate and obtain food are diminishing, especially during extreme winter conditions. The main objective of this research was an assessment of ungulates, impact on woody species, evaluation of damage forms and bark renewal phases of affected woody plants. The study area is located in western Slovakia in the southeast part of Male Karpaty Mts. After the very cold and long winter of 2012/2013, 34% of woody plants were damaged by bark stripping and biting on the forest locality and 53% of evaluated trees and shrubs were damaged by biting off shoots in the non-forest locality. Together, 262 woody plants belonging to 15 species were evaluated; the girth of tree trunks and stripped bark patches were measured. The most severely affected tree species, suffering from bark stripping and bitten-off sprouts, was Fraxinus excelsior; Acer campestre was also significantly affected. Results showed that woody plants provide a significant part of hoofed mammal nutrition (especially Capreolus capreolus and Cervus elaphus). The stripped bark dendromass per forested area of 625 m2 reached 3 m2. After the mild winter in 2014, the majority (93.7%) of previously affected Fraxinus excelsior trees in the forest locality had only old damages with renewed bark in different phases of regeneration. In the non-forest locality, 96% of young Fraxinus excelsior, damaged in the winter of 2013, shot up new sprouts. The mortality of affected trees was minimal (4−5%).
