“…Additionally, ecoregion and river size are given in Annex II of the WFD as factors determining the characteristics of a river. Also, the distinction between the ground water influenced subtype MPG from non ground water influenced subtype MP agrees with the results of KOHLER et al (1997), CARBIENER and ORTSCHEIT (1987), and EGLIN et al (1997.…”

The European Water Framework Directive requires ecological status classification and monitoring of surface and ground waters using biological indicators. To act as a component of the "Macrophytes and Phytobenthos" biological quality element, as demanded by the Directive, a macrophyte-based assessment system was developed for application in river site types in Germany. Macrophyte abundance data were collected from 262 sites in 202 rivers. Seven biocoenotic river site types were established using differences in characteristic macrophyte communities reflecting ecoregion, channel width, water depth, current velocity, water hardness, and ground water influence. For four of these river site types, a macrophyte assessment system was developed, for the remaining three river site types data were insufficient for developing an assessment system. Ecological status classification of river sites is based on the calculation of a Reference Index value, in some cases supplemented by additional vegetation criteria. The Reference Index quantifies the deviation of species composition and abundance from reference conditions and classifies sites as one of the five possible ecological quality classes specified in the Directive. The assessment of long river stretches with changing river site types along its course is discussed based on an example from the Forstinninger Sempt River, southeast Germany.

“…Some authors find a good correlation between plant species and water quality (Eglin et al 1997), while others find a poor correlation (Iliopoulou-Georgutaki et al 2003). In our study, plants represent a very good indicator of the decreasing environmental quality along the river Aniene.…”

From the source to the mouth of the Aniene River, a tributary of the Tiber near Rome, there is a multifactorial gradient of increasing disturbance and water pollution. We first investigated the variation of riverine and aquatic vegetation along the Aniene, analysing the floristic composition by means of transects comprising both water and shore. We then compared vascular plants and macroinvertebrates to establish which was the more reliable bioindicator of water pollution and disturbance in river habitats. The floristic dataset can be ordered according to the two axes of NMMDS. Axis I showed a high correlation with the Extended Biotic Index (EBI) (Spearman's rho = 0.89) and Hemeroby indicator of disturbance in plants (Spearman's rho = -0.70), and Axis II with Shannon diversity of plants (Spearman's rho = -0.67). These results have been summarised in two GIS maps, for EBI and Hemeroby, and allow to distinguish two sectors of the Aniene: upper and low-middle, correlated with geomorphology, density, type of settlement and degree of pollution. EBI and Hemeroby indicators collect information about environmental quality along different scales

“…This relative high number may be due to the high diversity of habitats created by the dynamics of the river (as shown by Bornette et al 2001) in spite of hydraulic management (straightening and canalisation). The aquatic habitats of the Rhine fringe are characterized by a broad range of vegetation communities: from mesotrophic to eutrophic vegetation (Trémolières et al 1993, Eglin et al 1997). In the Rhine cut-off channels conditions, nutrient level was highly related to the connectivity because of the specific hydrological functioning of large rivers as shown in Rhône and Danube (Bornette et al 1998, Janauer & Kum 1996.…”

“…Moreover a high nutrient content in water ensures a high development of biomass linked to a low or a high specific richness. Amoros & Bornette (2002), Amoros (in press) and Bornette et al(1998) Connection and trophy level (nutrient P and N content), are narrowly linked to the functioning of the Rhine floodplain (Trémolières et al 1993, Eglin et al 1997. Connected stretches are eutrophic to hypertrophic depending on the eutrophication of the river.…”
