Plant performance and PHE uptake Seed emergence. Our results show that in the polluted non-treated soils (C), seed emergence was totally inhibited, whereas it was promoted by the addition of gypsum mining spoil (GS) at any proportion (T1, T2, T3), both for Medicago sativa (84% in T1, 88% in T2, and 100% in T3) and Cynodon dactylon The Saint Gobain Drummond mine which is located between Kingscourt, County Cavan and Carrickmacross, County Monaghan, produces gypsum for the nearby plaster and plasterboard plant and for the production of cement by a number of regional producers.

Gypsum soils in drylands support important habitats for conservation of unique specialised flora that must be preserved. Gypsum habitats are destroyed, fragmented and degraded by human activities, and several limitations challenge the recovery of gypsum vegetation.

2. The many ways mining activities impact biodiversity. Mining affects biodiversity at multiple spatial scales (site, landscape, regional and global) through direct (i.e. mineral extraction) and indirect Gypsum is extracted from open-cast mines or underground mines using room and pillars mining methods. Gypsum is normally only screened to remove “fine particles” (mainly mudstones), then crushed and finely ground. The extrac-tion process implies an unavoidable impact on the land-scape and the natural environment. However, Biodiversity Stewardship in Gypsum Quarrying: our Best
