Previous research has looked into the effect of factors, such as the pH, water level, temperature, and nutrient concentration on peatland, separately. This paper looks at all factors, presenting a review of articles about the role of groundwater in peatlands, focusing on the negative effects of groundwater on Sphagnum (spp.) dominated bogs. Findings demonstrate that changes in water level, pH and calcium affect species composition, which can be seen as a negative effect. When defining a negative effect more strict, it can be concluded that only pH has a negative effect on Sphagnum dominated bogs, as findings suggest that high alkalinity led to rapid internal phosphate mobilization, peat disintegration and Sphagnum die-off. Die-off intensified with sulphate pollution. None of the articles really discussed groundwater in terms of origin, pathway, and related composition. In addition, the processes of acidification and methanogenesis are still not well known. Hopefully, this paper will encourage the inclusion of research on origin and pathway of groundwater, and on the different processes.
