Abstract
The site Damvallei is a lowland fen area, arisen by peat formation in
a former meander of the river Schelde. Peat digging created about
forty five pools, hosting unique Hydrocharition and Magnopotamion
vegetations (Natura-2000 habitat 3150). Spatial differences in
elevation and soil type (clay, loam and sand are all present in the
area) lead to a variation of well developed habitats with a profound
botanical diversification.The site has been designated as part of the
European Natura-2000 network.
Due to the detrimental effects of angling activities, these pond habitats
have locally perished. Restoration of these habitats is a main
objective of a EU-funded LIFE-nature project.A detailed biogeochemical
study has been conducted to investigate the possibilities for
restoration and spontaneous recolonisation of the ponds. This study
provided evidence-based, scientifically-sound instructions for
pond restoration, such as removal of the introduced planktivorous
and benthivorous fish species and re-introduction of the ‘flagship’
species Stratiotes aloides.The first results of these restoration actions
indicate a successful recovery of the originally present habitats.
