Erosion or plant succession - How to interpret the presence of arbuscular mycorrhizal fungi (Glomeromycota) spores in pollen profiles collected from mires

► The indicative value of arbuscular mycorrhizal fungi (AMF) in mires was examined. ► Combined palaeoecological and mycological methodology was used. ► AMF spores are ambiguous erosion indicators in peat. ► AMF spores are related with plants overgrowing mire surface.
