The complete destruction of primary vegetation and soil cover as a result of human activity is the most drastic example of disturbances in ecosystem functioning. Despite the fact that inactive limestone and dolomite quarries are relatively common in the southern part of the Silesian Upland (the Jaworzno Hills mesoregion), there are not many studies on the processes of transformation of landscape within them. The aim of our paper is to present preliminary results of research on overgrowing processes in the select objects using applied GIS methods. The studies show that differentiation of overgrowing processes in investigated quarries depend on the time that passed from the end of exploitation and of the type of surrounding landscapes. The major fragments of quarries were overgrown by species with a wide ecological spectrum, both herbaceous species (e.g. Calamagrostis epigejos) and pioneering trees (e.g. Betula pendula, Salix caprea). Additionally, especially on the edge of investigated quarries, plant communities form class Rhamno-Prunetea and grasses from Cirsio-Brachypodion pinnati union formed. In total, 145 species of vascular plants were identified, including 2 strictly protected and 7 partially protected taxons. Research is based on archival aerial photographs and the latest orthophotomaps from the 1950s to 2009. All cartographic materials were calibrated and registered in Poland CS92 coordinate system (EPSG: 2180). Registration and digitalization of vegetation patch ranges were conducted with applied MapInfo Professional software.

Migration and concentration of heavy metals in infiltration waters within unsaturated and saturated zones of a carbonate massif result from their mobility as well as anthropopression. The purpose of this project, carried out in 1995-2005, was to observe changes in the chemical composition of infiltration waters, especially Sr, Ba, Fe, Mn, and Zn concentration in precipitations, in soils and in caves within an unsaturated zone and a saturated zone situated in a carbonate massif. Field research was conducted in the Prądnik River’s drainage basin and at the Zakrzówek horst in Kraków. The chemical and mineralogical composition of limestone samples from 11 different quarries and natural exposures in the Kraków Upland were studied. The mineralogical research was conducted using the Roentgen diffraction method. The concentration of Sr, Ba, Fe, Mn and Zn in 700 samples from precipitation, caves and saturated zone waters was analysed. The determinations were made using mainly the ICP-AES Plasma 40 and ICP-MS Elan method. To assess the quality aspects of the migration of heavy metals, the results of the geochemical modelling were accounted for using the PHREEQC software. The hydrochemical research has shown distinct variability of concentrations of the analysed minor elements in different forms of precipitation (the highest concentrations being observed in sleet and the lowest in pure snowfall). In rainwater as well as in waters of the unsaturated and saturated zones, quantities of the five chemical elements appeared in the following decreasing order: Fe>Zn>Mn>Sr>Ba and Sr>Ba>Fe>Zn>Mn. The chemical composition of infiltration waters in the carbonate massif changes vertically. The fundamental trends in the waters of this area include an increase of Sr and Ba concentrations, a decrease of the concentration of Zn, and static concentrations of Fe and Mn.

Our paper presents a range of research carried out for environment protection and management using GIS applications. It documents 20 years of scientific achievements through Polish-Croatian cooperation in the GIS field. The resultant body of work includes, inter alia, scientific publications that are the result of 20 international conferences organized in the framework of said cooperation efforts. The study included articles published in 1994 to 2012 and those drafted for publication in 2013. An analysis of select articles was done in accordance with the accepted range of topics in order to categorize and define the research extent. Among the distinguished 19 subject categories, most of the articles were concerned with: environmental management, nature conservation, landscape management, biodiversity, sustainable development, meteorology, and climatology.

Ecohydrological monitoring was conducted in the period of 1999-2013 (and beyond) in the riverhead section of the Kłodnica Valley, in the riverside ecosystems in the southern part of the Silesian Upland. The aim of this study was to analyze and evaluate the impact of mining on the changes in water conditions and their impact on plant ecosystems connected with waterlogged habitats in the valley. The monitoring included observations on the variability of the water table, the size of mining subsidence and the scale of ground deformation. In order to monitor the range of Allium ursinum and Veratrum lobelianum, five permanent plots of 100 m2 each were established. During coal extraction (2000-06) the water table depths ranged from 0 to 2.4 m in the uplands, and from 0 to about 1 m in the valley, and the waterlogging of the substrate was dependent on precipitation conditions (amount and distribution of rainfall throughout a year). At that time, the surface of the area lowered by a maximum of 1.78 m. After the coalmine operation ceased, i.e. in the period of 2007-13, the subsidence significantly declined and did not exceed 15 cm. The monitored populations of Allium ursinum L. and Veratrum lobelianum Bernh. did not show considerable changes in terms of the area they occupied. However, a trend was observed to increase their ranges not only in the plots but also in the whole area. Local decrease in the ranges of the tested species was caused by forest management carried out at the same time. According to the results of the monitoring, the changes evoked by the mining activities are dependent on geological and lithological conditions, the position of the water table, the size of the mining operation, and ground subsidence, as well as the technology of extraction. It was found that the impact of mining on riparian ecosystems in the study area has not caused negative changes in their functioning.

As a pioneer species of R life strategy Salix acutifolia is an early coloniser, promoting the formation of soil in sandy areas. Initially, the area around the base of S. acutifolia is colonised by cryptogams. Then, soil formation takes place as S. acutifolia grows and the canopy develops. As a broadleaved species, S. acutifolia produces a lot of biomass. Good habitat conditions are created for the development of microorganisms accelerating the process of leaf decomposition and humus formation. This encourages the subsequent entry and growth of vascular herbs under the canopy of S. acutifolia, which hasten the process of soil and plant succession. After 5 years, a large number of Pinus sylvestris seedlings develop under the S. acutifolia canopy. P. sylvestris outcompetes S. acutifolia for nutrients and eventually eliminates S. acutifolia from the site by contributing to soil acidification. P. sylvestris then becomes the dominant influence on the physico-chemical properties of the soil.

The aim of our paper is to identify the main trends in changes in land use of select urban parks in Sosnowiec and Będzin towns during 1927-2009 in light of changes to the urban areas. Research included two urban parks: Sielecki in Sosnowiec and Góra Zamkowa in Będzin. The analysis was based on old maps (from 1927, 1960s/70s, and 1990s) and the latest available orthophotomaps of the study area (2009). The results obtained on the basis of geographical information systems (GIS) shows significant differences, both in terms of spatial and quality changes in the land use in all urban parks, conditioned by their location in the different types of landscapes. The identified changes are linked to the wider range of functions taken over by parks, and also of changes in urban planning strategies. The GIS methods were helpful in interpretation of identified changes. Increasing forest areas is observed in the last research period and has a connection with the flora of both parks. The role of urban parks is particularly noticeable in strongly urbanized and industrialized areas – in the urban-industrial agglomeration and conurbation. The urban parks in these areas are an interesting problem in terms of geographical, botanical, and landscape ecology research. The documentation, monitoring, and protection of the oldest and the most valuable parts of the urban parks (urban forests) are important in light of the fact that urban parks are linked with local history.
