The aim of this study was to investigate the soil microbial communities of a phosphogypsum waste heap. The soil microbial community structures can differ over time, as they are affected by the changing environmental conditions caused by a long-term exposure to different kinds of pollutions, like is the case of soil in the post-production waste area in Wiślinka (in the northern part of Poland) currently undergoing restoration. Our analyses indicated that the most abundant phyla were Proteobacteria, Acidobacteria, and Actinobacteria, and generally such an abundance is common for most of the studied soils. The most dominant class were Alphaproteobacteria, with their participation in 33.46% of the total reads. Among this class, the most numbered order was Sphingomonadales, whereas among this order the Sphingomonadaceae family was the most abundant one. The Sphingomonadaceae family is currently in the center of interest of many researchers, due to the ability of some of its members to utilize a wide range of naturally occurring organic compounds and many types of environmental contaminants. This kind of knowledge about microbial populations can support efforts in bioremediation and can improve monitoring changes in the contaminated environments.

The purpose of the article is to determine changes in the development and relief of the post-extractive area that result from transformations related to aggregate mining. The area around the gravel quarry in Tarnowa was selected as the test area. On the basis of cartographic summaries and analyzes, changes in the topography were shown. Thanks to the field study using a drone, the development of the area after and during the exploitation of natural aggregate was presented. The direction of forest remediation in which the changes are heading is indicated. The concept of special reclamation was introduced, which will allow the development and use of post-mining areas in an alternative way.

Celem artykułu jest określenie zmian w zagospodarowaniu oraz rzeźbie obszaru powydobywczego, które wynikają z przekształceń związanych z eksploatacją kruszywa. Jako obszar testowy wybrano okolice żwirowni w Tarnowej. Na podstawie zestawień i analiz kartograficznych pokazano zmiany w rzeźbie terenu. Dzięki fotografiom wykonanym z drona przedstawiono krajobraz terenów dawnej i obecnej eksploatacji kruszywa naturalnego. Wskazano kierunek rekultywacji leśnej, w którym następują zmiany. Przybliżono oraz zasugerowano koncepcję rekultywacji specjalnej, która umożliwi zagospodarowanie i wykorzystanie terenów pokopalnianych w alternatywny sposób.
