“…They are recommended as supporting methods for other biological, physical, or chemical methods of surface water restoration (e.g., phytoremediation, use of synthetic zeolites, or injection of salt into bottom sediments) (Gao et al 2023 ; Tarczyńska et al 2001 ). A particularly recommended biological method for controlling water blooms in reservoirs is the creation of ecotone zones consisting of macrophytes that prevent the resuspension of sediments (containing, among other things, nitrogen and phosphorus compounds that are food for algae that cause eutrophication) that accumulate harmful substances in their tissues (e.g., heavy metals) and that perform important ecological functions (e.g., as shelter for other groups of organisms) (Chen et al 2019 ; O’Hare et al 2018 ; Wiatkowski 2015 ).…”

Since reservoirs perform many important functions, they are exposed to various types of unfavorable phenomena, e.g., eutrophication which leads to a rapid growth of algae (blooms) that degrade water quality. One of the solutions to combat phytoplankton blooms are effective microorganisms (EM). The study aims to evaluate the potential of EM in improving the water quality of the Turawa reservoir on the Mała Panew River in Poland. It is one of the first studies providing insights into the effectiveness of using EM in the bioremediation of water in a eutrophic reservoir. Samples for the study were collected in 2019–2021. The analysis showed that EM could be one of the most effective methods for cleaning water from unfavorable microorganisms (HBN22, HBN36, CBN, FCBN, FEN) — after the application of EM, a reduction in their concentration was observed (from 46.44 to 58.38% on average). The duration of their effect ranged from 17.6 to 34.1 days. The application of EM improved the trophic status of the Turawa reservoir, expressed by the Carlson index, by 7.78%. As shown in the literature review, the use of other methods of water purification (e.g., constructed wetlands, floating beds, or intermittent aeration) leads to an increase in the effectiveness and a prolongation of the duration of the EM action. The findings of the study might serve as a guide for the restoration of eutrophic reservoirs by supporting sustainable management of water resources. Nevertheless, further research should be conducted on the effectiveness of EM and their application in the remediation of eutrophic water reservoirs.

“…Many authors have shown that methods of biological treatment of degraded lakes are most appropriate in most cases (Moss, 1990;Cook et al, 2013;Cook et al, 2016). The introduction of eco-tones in the structure of the reclaimed water of the reservoir have a positive effect on the ecological status of the freshwater environment (Chen et al, 2019). A general increase in species biodiversity of the littoral zone plants was also visible in 2019.…”

Aim of the study Study of the effects of the microbiological bioremediation process carried out as a part of a purification process of a reservoir in Kamienna Góra. Material and methods A number of field measurements were made, i.e. thickness of bottom sediments, light transmission, and physicochemical analyses of waters. Activities undertaken in the bioremediation process were described. The final effects have been characterised. Results and conclusions The microbiological bioremediation process has contributed to the reduction of bottom sediments (organic fractions) by 30-100% at the selected measuring points. There was an improvement in the euphotic zone conditions from 70-100% in the examined points. The level of organic pollutants in water has also partially improved. The concentrations of the studied nutrients did not decrease, and even in some points they increased in 2018. Despite visible changes in the water quality in the reservoir, and almost complete elimination of organic fractions in bottom sediments, an increase in nutrients in the flood waters could be expected. In the last year of research, complete elimination of algal blooms was noted and ecotones were located in places of their earlier occurrence. The reservoir is still exposed to pressure from pollutants brought in by waters of the Zadrna River. If sources of pollution are not eliminated, this type of treatment will have to be repeated in subsequent seasons to maintain the quality of the reservoir water.

“…Riparian forests margin water bodies and, therefore, have certain floristic peculiarities due to regular water flow, sediments and nutrients. The process of deforestation and fragmentation of the natural vegetation leads to the physical degradation of the soil, resulting in erosion and consequently to the silting of rivers, leading to the decline of springs (Albuquerque et al, 2013;Chen et al, 2019;Nóbrega et al, 2020). Therefore, the ecological restoration of riparian environments aims to initiate or to accelerate the recovery of these ecosystems relative to their health, integrity and sustainability (Chen et al, 2019).…”

Establishment of native seedlings species as an indicator of ecological restoration of riparian forest, Cerrado, DF, Brazil

This study evaluated the survival of seedlings of native species of Cerrado - Brazil and its potential as an indicator of ecological restoration of riparian forests. The factors affecting survival were also analyzed. The experiment consisted of three planting models with three replications (T1 = nucleation: Anderson model; T2 = nucleation: Anderson model + artificial perches; T3 = filling line and diversity line). The influence of factors such as leaf herbivory, stem herbivory, absence of leaves (predation, dehydration or malnutrition) and sprouting/regrowth survival were assessed by cluster analysis. The survival rates ranged from 58.6 to 100% (average 73.6%). Out of eighteen species, fifteen showed survival rate above 60%, and could be potentially used in the restoration of degraded areas. The hierarchical clustering using survival efficiency and biotic factors resulted in the distinction of two groups of species with high frequency of leaves and stem herbivory, differing statistically (test “t”, p < 0.05) in the sprouting and regrowth. The survival efficiency shows potential of being used as a restoration indicator.
