The aim of the project is to restore fish species diversity habitat restauration in brooks and rivers that are specified as area’s that need special protection from to the Habitat Directive. Special intention will be given to rheofilic species, as there has been a severe decline in their distribution in Flanders over the past decades. Habitat rehabilitation measures will be worked out after a study of the habitat use of selected key species and an inventory of habitat availability in the rivers. Afterwards, post project appraisal will be carried out, to evaluate the restoration measures and to direct future projects.
