Introduction Analysis of aboveground vegetation and soil seed bank is an important source data on the state dynamics vegetation. It especially in landscapes exposed to disturbances, which have lost their functions. For our research, a post-mining area region Upper Silesian Black Coal Basin was selected, whose relief ecosystems are strongly disturbed by underground mining currently also affected ongoing climate change. Method Data collection for research took place territory two waterlogged subsidence basins Karvina region, Czech Republic. We evaluated 30 phytosociological releves using techniques Zurich – Montpellier school 540 cores cultivation extraction method. Results In above-ground vegetation, 115 plant species were identified. By cultivating samples, we determined 60 from 1,487 seedlings, method 66 5,999 seeds. A statistically significant effect presence tree layer number obtained demonstrated. There difference between selected analysis methods terms length captured seeds mass. Discussion The construction rarefaction curve demonstrated that use leads greater capture species. similarity composition correspond similarities observed other studies degraded habitats. Very low probably caused highly variable distribution time space.

Abstract The assessment of seed banks could provide useful hints towards ensuring restoration planning and invasive species management. In this study, the impacts two invaders such as Hyptis suaveolens Urena lobata on soil were investigated. We also assessed characteristics at invaded sites. This was achieved using 10 sites each for H. suaveolens- U. lobata-invaded habitats -non-invaded making a total 30 collected 200 samples from habitat type. A seedling emergence method used to determine bank recruitment both plants. diversity indices above-ground vegetation by plants significantly lower than those non-invaded Only plant emerged five when compared with where 53 emerged. larger portion seeds located in soil’s layer all while found upper layers there are significant associations between habitats. have highest percentage viable seeds.

Saudi Arabia has implemented ambitious environmental protection programs by creating numerous nature reserves throughout the country. Establishment of latter led to farm abandonment and initiation ecosystem recovery processes. Agricultural practices are known impact structure physicochemical properties soils while also often markedly affecting natural restoration Moreover, weed proliferation in crop fields may modify soil seed banks (SSB), thereby impacting subsequent vegetation recovery. Therefore, it is essential assess SSB compositions degraded sites, such as abandoned farms (AF), so identify species design efficient strategies hyperarid ecosystems. In this study, upper deep layers, standing compositions, chemical were analyzed compared for two ecosystems (NE), orchards (AO), AF, evaporite basins (EB). NE, AO, EB all exhibited similar properties, suggesting that former agricultural activities have been guided a fine understanding local environments. Agriculture had impacted composition observed germinable SSBs, which could be partly explained property modifications. The findings highlighted SSBs would warrant detailed study prior designing ecological strategies, drivers horizontal vertical dissemination should explored gain further insight into patterns adapt accordingly.
