| 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.
