Effects of hydro-morphological restoration of Dutch lowland streams on macrophytes : relations between fine scale physical features and aquatic plants communities

As a consequence of intense channelisation, agriculture and urbanization, 96% of Dutch streams are nowadays directly impacted by human activities, thus affecting stream biota. In response to this general stream degradation, many restoration projects were carried out over the past decades to improve stream habitat quality, but often leading to no ecological improvement. In 2010 and 2011, Dutch waterboards undertook innovative restoration measures encompassing reshaping the stream bed to make it less wide and deep, flattening the banks' slope and creating meanders. To assess the impact of these... Mehr ...
