Short description: Restoration had significantly improved the diversity of mesohabitats in 83 per cent of the studied river sections. For microhabitats, restoration had a significant positive effect on diversity at 69 per cent of sites but a significant negative effect at 15 per cent of sites. More specifically, the impacts of restoration on river site characteristics such as shore length, habitat width and the actual number of mesohabitats and microhabitats were greater in Southern Europe and mountainous regions. Active restoration projects, such as removing banks and placing logs in the river channel, had a greater effect on the characteristics of mesohabitats and microhabitats, particularly for Southern European sites and Central European mountain rivers. The impact of passive restoration projects, such as abandoning river maintenance and removing livestock, was smaller and mainly restricted to mountain rivers in Central Europe. The effect of restoration on the biodiversity of benthic invertebrates was small or not detectable. This supports the results of previous studies which have found that enhanced habitat diversity has little or no effects on benthic invertebrate biodiversity.
