Climate change is a common factor that contributes to the growth or decline of animal populations. The present study, conducted using the Species Distribution Model, highlights the fact that despite the recognized negative impact of wild boar (Sus scrofa) on semi-natural areas and agricultural systems worldwide, the species remains poorly studied. According to projections for Representative Concentration Pathways (RCP) 4.5 and 8.5, increased clusters of wild boar abundance are expected to emerge around fragmented species assemblages by 2070. Sus scrofa is an extremely destructive and rapidly spreading invasive species whose movement appears to be facilitated by humans. As a consequence, many endemic plants are threatened with extinction. Biological corridors between fragments with poor conservation status should be linked to priority areas for adequate protection. The creation of preserved landscapes in territories separated from semi-natural ecosystems is recommended. Additionally, these measures can help mitigate the negative impact of S. scrofa on local biodiversity. Continuous monitoring and adaptive management strategies will be crucial for long-term conservation of the affected areas. Environmental protection efforts must prioritize the restoration of natural habitats and the implementation of strict regulations to control the spread of this invasive species. Collaborations between conservation organizations, governments, farmers, and local communities are essential to ensure effective wild boar management and the preservation of arable land and forests. Moreover, public awareness campaigns about the environmental impact of wild boar and the importance of conservation efforts are critical for garnering broader support.

Na rekultywowany teren pogórniczy naniesiono substrat glebowy zawierający osady ściekowe. Oznaczono zawartość metali ciężkich w próbkach nowo powstałej gleby pobranej z tego terenu i gleby kontrolnej. Obliczono wskaźnik zanieczyszczenia dla substratu glebowego i Taraxacum officinale metalami ciężkimi na obszarze poeksploatacyjnym. Stwierdzono korzystny wpływ materiału doglebowego na zdegradowane tereny pogórnicze. Odpady przemysłowe i komunalne mogą być wykorzystane w gospodarce o obiegu zamkniętym i rekultywacji terenu.

Sewage sludge mixt. was deposited on the post-mining area. The content of heavy metals in soil samples was taken from both study and control site. The heavy metal contamination index for the soil substrate and Taraxacum officinale in the post-mining area was calculated. The beneficial effect of soil substrate on reclaimed post-mining areas was found. Industrial and municipal waste can be used for a circular economy and land reclamation.
