Hydrological, soil chemical and ecological effects of Climate Change in species rich fens


Rich fens are characterised by their low productivity, permanent wetness and base richness, with P availability often limiting primary production. Prolonged periods of summer drought may drastically alter the redox and pH conditions in the root zone. Such events are likely to affect the soil and soil solution chemistry (e.g. P availability). Increased P availability may in turn lead to increased net primary production and, eventually, decreased species richness. In this Global Change study, we evaluated to what extent prolonged periods of summer drought which are expected to occur more frequently in Climate Change scenarios affect the hydrology, soil chemistry and ecology of species-rich fens.
