We examined pressure response relationships using data collated from the National Monitoring Network. We plotted parameters of phytoplankton, aquatic macrophytes and water transparency across TP concentrations in the two types of natural lakes. In TP threshold values of 20-40 μg/l changes in biological communities and water transparency were observed in both lake types.

We analyzed data from the National Monitoring Network from 2019-2021 for 16 freshwater lakes in Greece. Water transparency, ionic composition and Total Phosphorus (TP) were correlated with major phytoplankton groups (chlorophytes, dinoflagellates, cryptophytes, bacillariophyceae and cyanobacteria). Based on both phytoplankton and physicochemical parameters, two groups of lakes were formed in cluster analysis, corresponding a) to deep warm monomictic and b) shallow and very shallow polymictic lakes. With regard to the impact from phosphorus loading, in both groups of lakes, a considerable increase of cyanobacteria biomass along a TP gradient was observed. Chlorophytes showed a statistically significant response in relation to TP in shallow and very shallow lakes.

The objectives of this study were a) to investigate spatial and temporal variations of benthic macroinvertebrate communities in Lake Kastoria and b) to assess the lake water quality with the use of a WFD-compliant national method. Samplings were undertaken at the littoral zone of the lake at 5 selected sites during spring 2017 and 2021, according to the Hellenic Lake Littoral Benthos (HeLLBI) assessment method. Non-metric multidimensional (NMDS) scaling and one-way analysis of similarity percentages were applied to visualize similarities and to identify the taxa responsible for the discrimination in benthic macroinvertebrate communities between different sampling periods, among sites and water quality classes. In total, 5569 individuals were collected and 37 taxa groups were identified. NMDS plot provided a useful display of the actual multivariate distance among samples (stress value: 0.14). Benthic invertebrate communities showed considerable spatial variation at local scale (sampling site level) except for one site but no clear temporal variation. The mean EQR value of HeLLBI showed moderate water quality of the lake. All sites showed no change in their water quality across time except for 2 sites that improved (poor to moderate and good respectively). Benthic macroinvertebrates communities at good water quality sites differed in composition and showed higher biodiversity compared to those at moderate and poor sites. Management measures should be site-adapted in Lake Kastoria and priority could be given to the conservation and restoration of the littoral zone.},

abstract = {Lake Koronia, Greece, is a wetland of international and European importance (Ramsar and Natura 2000 site). The lake has deteriorated in terms of habitats, water quantity and quality since 1995, resulting in mass fish and bird deaths. We monitored abiotic and biotic (aquatic macrophytes) parameters between 2015 and 2021 to investigate recovery progress, following implementation efforts of a restoration plan. Abiotic conditions were recorded monthly/seasonally, while vegetation data were recorded in two periods (June 2017, 2020). After an initial considerable increase in water level, mean annual values fluctuated at around 70-71 m asl. Water transparency values were low while conductivity values were high. Three vegetation units were present: Lemnetea, Potamogetonetea and Phragmitetea, represented by few taxa. Helophytic taxa formed a narrow littoral reedbed (< 10 % of the lake area). Few rooted hydrophytes were present but limited to sparse patches (< 5 % of the total abundance).

abstract = {Assessment methods had been intercalibrated for lake types LM 5/7 (deep siliceous reservoirs) and LM 8 (deep calcareous reservoirs) (de Hoyos et al. 2014). In the first round of IC that Greece participated, boundaries for individual phytoplankton metrics (chlorophyll-a, total biovolume, percentage of cyanobacteria, IGA and MedPTI) were agreed (using option 1 of IC) and formally included in the 200 8 EC Intercalibration Decision. During the second round of IC, national assessment methods based on the above metrics (NMASRP for Cyprus and Portugal, MASRP for Spain and NITMET for Italy) were intercalibrated for LM 5/7 and LM 8 types. Greece had not started the operation of the monitoring network at that time, and thus had not submitted its national assessment method for the second round of IC. The operation of the Greek monitoring network started in 2012, following the publication of a Joint Ministerial Decision in 2011. Fifty lake water bodies have been included in the monitoring network, out of which 15 are LM 5/7 and 5 are LM 8 reservoirs. The national phytoplankton assessment method applied for Greek LM 5/7 and LM 8 reservoirs is the New Mediterranean Assessment System for Reservoirs Phytoplankton (NMASRP), that has been intercalibrated in the Med GIG, as applied by Cyprus and Portugal (i.e. the metric percentage of cyanobacteria is replaced by the metric biovolume of cyanobacteria, in order to account for algal blooms) (de Hoyos et al. 2014). Spain uses MASRP (i.e., with the metric percentage of cyanobacteria). NMASRP addresses eutrophication pressure in Mediterranean reservoirs. This report does not discuss the development of new or revised ecological assessment method for phytoplankton according to finalized IC results, but the application of the existing NMASRP phytoplankton assessment method as intercalibrated in the Med GIG (including existing MEP values and EQRs), into the national dataset. NMASRP values are calculated as annual mean. This dataset contains data collected during the 2012-2015 sampling campaign, and in particular 53 NMASRP values for LM 5/7 and 18 NMASRP values for LM 8 reservoirs arising from 139 and 56 samplings, respectively.},
