“…The restoration method supporting the growth of the submerged vegetation originates from the Theory of Alternative Stable States which assumes that inland reservoirs can exist under two alternative regimes: the transparent water regime (with the predominance of macrovegetation) or the turbid water regime (with the predominance (Scheffer, 1998;Wetzel, 2001;Moss, 2003). The literature indicates a series of successful examples of using the submerged vegetation in the process of restoration of shallow, eutrophic reservoirs (inter alia Pan, 2008;Dai, 2014;Li, 2014). The role of submerged vegetation is, inter alia, to: increase the stability of bottom sediments, improve the aerobic conditions, reduce the concentration of biogenic substances in the pelagic zone and their accumulation in the bottom sediments, as well as to provide shelter for zooplankton (whose main food is phytoplankton) and discharge allelopathic compounds that inhibit the growth of phytoplankton (Scheffer, 1998;Górniak and Dunalska, 2005;Walstad, 2013;Dai, 2014).…”

Due to complex biophysicochemical interactions, the state with the predominance of macrovegetation persists in a relatively wide range of fluctuations in the parameters of the habitat (the stability of the ecosystem); the shift to the state with the predominance of phytoplankton usually occurs exclusively due to a strong anthropogenic pressure, that may, for example, be connected with an intense inflow of biogenic substances to the reservoir, or to a significant disturbance of relationships within the trophic chain.…”

This paper presents the proposed criteria for the evaluation of mine subsidence reservoirs in areas of underground mining extraction with regard to the ability of such reservoirs to be restored and adapted to perform natural and social functions in urban space. The criteria for the evaluation of the reservoirs' potential (P) have been analyzed, and factors crucial to the suitability (S) of the aforementioned reservoirs to be ecologically restored with the implementation of the method using submerged vegetation have been identified. The ability of the proposed criteria (qualitative -yes/no and quantitative within the range of -2, -1, 0, 1, 2) to be applied has been verified based on 4 randomly selected mine subsidence reservoirs in Upper Silesia (Poland). The obtained results show that the reservoirs are different in the evaluated potential (P: from -1 to 3) and suitability (S: from -3 to -1). It has been concluded that the 3 proposed stages of the evaluation of reservoirs' potential and suitability to be adapted enable the categorization and determination of bodies of water for restoration activities. This is even of greater significance as, at present, mine subsidence reservoirs constitute the majority of anthropogenic reservoirs occurring in the post-mining areas.

“…On some occasions, facilitation has been the proposed mechanism that may enhance the colonization of several submerged hydrophytes planted at the same time [ 98 ]. Thus, Dai et al [ 99 ] proposed using the combination of C. demersum and M. verticillatum as the best choice for ecological restoration of eutrophic water bodies. The charophyte Chara vulgaris has also been used for replanting in eutrophic wetlands due to its high-nitrate concentrations tolerance and because it is a r-strategist that produces large amounts of oospores [ 100 ].…”

Wetland Restoration with Hydrophytes: A Review

Restoration cases with hydrophytes (those which develop all their vital functions inside the water or very close to the water surface, e.g., flowering) are less abundant compared to those using emergent plants. Here, I synthesize the latest knowledge in wetland restoration based on revegetation with hydrophytes and stress common challenges and potential solutions. The review mainly focusses on natural wetlands but also includes information about naturalized constructed wetlands, which nowadays are being used not only to improve water quality but also to increase biodiversity. Available publications, peer-reviewed and any public domain, from the last 20 years, were reviewed. Several countries developed pilot case-studies and field-scale projects with more or less success, the large-scale ones being less frequent. Using floating species is less generalized than submerged species. Sediment transfer is more adequate for temporary wetlands. Hydrophyte revegetation as a restoration tool could be improved by selecting suitable wetlands, increasing focus on species biology and ecology, choosing the suitable propagation and revegetation techniques (seeding, planting). The clear negative factors which prevent the revegetation success (herbivory, microalgae, filamentous green algae, water and sediment composition) have to be considered. Policy-making and wetland restoration practices must more effectively integrate the information already known, particularly under future climatic scenarios.

“…The use of plants for puri cation aids in realizing the removal of pollutants while maintaining economic value. Studies have found that plant diversity and species richness are important factors that affect the removal of pollutants by plants (Dai et al 2014;Zeng et al 2017). Several combinations of wetland plants, such as Iris minutoaurea, Acorus calamus L. and cattail, can signi cantly increase the removal rates of TN and TP in wastewater (Zhu et al 2017).…”

Aquatic plants have attracted wide attention because of their low cost and high level of resource utilization. In order to study the effects of emergent and submerged plants on the puri cation of different concentrations of wastewater, two common aquatic plants found in Northeast China, Iris ensata Thunb. and Potamogeton malaianus Miq., were selected Under static conditions, nitrogen and phosphorus removal from simulated wastewater with different concentrations (high, medium and low) and lake samples of Nanhu Park, Changchun, Jilin Province, China, were studied. The results showed that the removal rate of total nitrogen (TN) in medium-and high-pollutant concentration water samples and total phosphorus (TP) in medium-and low-pollutant concentration water with I. ensata reached more than 75%. The removal rate of TN in the medium-pollutant concentration water with P. malaianus reached 71.4%, while the removal e ciency of TN and TP in the low-pollutant concentration water was higher than 80%. It is more advantageous to use plants to purify high-pollutant concentration water after further puri cation. The puri cation plants suitable for medium-pollutant concentration water are limited, but under low-pollutant concentration water conditions, there are more diverse options regarding the choice of wastewater puri cation plants. In the Nanhu lake samples, I. ensata had the highest removal rates of TN (80.38%), and TP (85.62%). This study shows that both I. ensata and P. malaianus can be used as aquatic plants to restore the water quality of urban lakes. A reasonable combination of different plants for addressing different pollutants is more bene cial to improve the puri cation effect. This research provides an important basis for the phytoremediation and treatment of urban domestic wastewater and urban surface water bodies in northern China.
