Development of tools for ecological quality assessment in polish marine areas according to the Water Framework Directive. Part III — Secchi depthThe implementation of the EU Water Framework Directive (WFD) requires ecological status quantification on the basis of biological and physico-chemical parameters, and an assessment of reference conditions and relevant environmental pressures for the construction of response curves. In this study the linking of water transparency, a proposed eutrophication indicator, to environmental pressure parameters was examined in the Polish sector of the Baltic Sea. Statistically significant linear correlations were detected between nutrient concentrations in sea water and Secchi depth, and between nutrient riverine loads and Secchi depth. The magnitude of acceptable deviation from reference conditions is also discussed.

Development of tools for ecological quality assessment in Polish marine areas according to the Water Framework Directive. Part I - NutrientsAssessment of the ecological status of an aquatic environment according to the European Union Water Framework Directive (WFD) requires the determination of a link between the observed status of the marine ecosystem and catchment loading as well as the establishment of criteria for ecological status definitions. This article presents the results of a study identifying links between environmental pressures in the Polish sector of the Baltic Sea and state parameters applied in the assessment of eutrophication. Strong, statistically significant correlations were found between riverine loads of nutrients and their marine concentrations even in relatively short time data series.

AbstractA set of classification methods was developed for the Polish coastal and transitional waters regarding the biological quality elements — phytoplankton, macrophytes and macroinvertebrates as required by the EU Water Framework Directive. Mean summer chlorophyll-a and total summer biomass of phytoplankton were proposed as indicators in the phytoplankton assessment. Macrophytes were assessed by the Macrophyte Quality Assessment Index, including biomass and percent bottom coverage of the selected taxa. Macroinvertebrate assessment was based on a biotic index comprising abundance, dominance structure, taxonomical richness and species sensitivity/tolerance to eutrophication. A preliminary assessment of the ecological status revealed that the coastal and transitional waters failed to reach a ‘good’ ecological status.

AbstractThe EU Water Framework Directive (WFD) aims to protect the ecological status of coastal waters. To establish acceptable boundaries between good and moderate ecological status, the WFD calls for reference conditions practically undisturbed by human impact. For Denmark, the nitrogen (N) concentrations present around year 1900 have been suggested to represent reference conditions. As the N load of coastal waters relates closely to runoff from land, any reduction in load links to agricultural activity. We challenge the current use of historical N balances to establish WFD reference conditions and initiate an alternative approach based on parish-level land-use statistics collected 1896/1900 and N concentrations in root zone percolates from experiments with year 1900-relevant management. This approach may be more widely applicable for landscapes with detailed historic information on agricultural activity. Using this approach, we find an average N concentration in root zone percolates that is close to that of current agriculture. Thus, considering Danish coastal waters to be practically unaffected by human activity around year 1900 remains futile as 75% of the land area was subject to agricultural activity with a substantial potential for N loss to the environment. It appears unlikely that the ecological state of coastal waters around year 1900 may serve as WFD reference condition.

The history of monitoring transitional water fish in Scotland is briefly outlined. The requirements of the EU Water Framework Directive are explained and how this applies to the monitoring of transitional water fish communities in Scotland is described. The development of a monitoring programme for Scotland is outlined, including sampling methods and strategies. Six transitional waters were selected as representative for Scotland covering three different types of transitional water. A multi-metric tool, the Transitional Water Fish Classification Index was used to assess the ecological status of the fish communities in these waters and the operation of the different metrics and the creation of appropriate reference conditions is explained. The assessment tool was applied to survey data from 2005 to 2018, although only the more recent data fully met the tool requirements. The species composition and abundances in the respective transitional waters were compared. The fully valid surveys were all classed as of Good or High status, indicating the fish communities in all the representative transitional waters appeared to be in good ecological health. The efficacy of the different metrics is considered and some issues with Metric 2, enumerating migratory species, are discussed at length. A new multi-metric tool, the Estuarine Multi-metric Fish Index, is briefly discussed and its introduction for the assessments in Scotland is recommended.

First Time

In the frame of the European Water Framework Directive (WFD, 2000/60/EC), a macroalgae based index (CARLIT) was applied along the Sicilian coastal water bodies (WBs) in order to assess for the first time their ecological status and collect accurate information on the distribution and abundance of shallow-water communities, especially of those most sensitive. The ecological quality ratio values, sensu WFD, showed “high”/“good” levels in all WBs with lushy forests of Cystoseira amentacea except two with “moderate” level due to the presence of stress-tolerant species related to local factors.
