“…Sediments also should have a sufficiently high share of organic material and may not contain toxic substances. Protection against grazing is especially important as long as plant biomasses and expansion on the target site are low (Lauridsen et al, 1993 [ 94 ], Irfannulah and Moss 2004 [ 93 ], Hilt et al, 2006 [ 80 ], Moore et al, 2010 [ 141 ], Jeppesen et al, 2017 [ 77 ], Rohal et al, 2021 [ 142 ], van de Weyer et al, 2021 [ 83 ]; Figure 4 ).…”

Re-establishment of submerged macrophytes and especially charophyte vegetation is a common aim in lake management. If revegetation does not happen spontaneously, transplantations may be a suitable option. Only rarely have transplantations been used as a tool to support threatened submerged macrophytes and, to a much lesser extent, charophytes. Such actions have to consider species-specific life strategies. K-strategists mainly inhabit permanent habitats, are perennial, have low fertility and poor dispersal ability, but are strong competitors and often form dense vegetation. R-strategists are annual species, inhabit shallow water and/or temporary habitats, and are richly fertile. They disperse easily but are weak competitors. While K-strategists easily can be planted as green biomass taken from another site, rare R-strategists often must be reproduced in cultures before they can be planted on-site. In Sweden, several charophyte species are extremely rare and fail to (re)establish, though apparently suitable habitats are available. Limited dispersal and/or lack of diaspore reservoirs are probable explanations. Transplantations are planned to secure the occurrences of these species in the country. This contribution reviews the knowledge on life forms, dispersal, establishment, and transplantations of submerged macrophytes with focus on charophytes and gives recommendations for the Swedish project.

“…Research on Lake Apopka has highlighted the rapid eutrophication, the potential for restoration, and restoration progress and setbacks, with a focus on nutrient removal and planting vegetation to facilitate recovery (Dunne et al 2015;Dunne et al 2012;Slagle and Allen 2018). More recent work has examined the best ways to maximize successful plantings and restoration efforts for submersed aquatic vegetation (SAV) (Reynolds et al 2021;Rohal et al 2020a) and utilization of SAV by fish Looby, Reynolds, Adams, Walsh, et al 2021). General interest in the habitats and plant communities of Lake Apopka is the result of increased public access and enthusiasm for improving these habitats for recreation, and therefore there is considerable interest in the lake's plant community.…”

“…Thus, aquatic macrophytes are widely used as a biological indicator in monitoring and assessment systems developed in the context of WFD for lakes [19,23]. Moreover, the monitoring of temporal and spatial patterns of the growth status and the distribution of aquatic vegetation, in relation to environmental factors, is of great significance, especially considering its role in the ecological restoration of lake ecosystems [24,25].…”

Aquatic vegetation is an essential component of lake ecosystems, used as a biological indicator for in situ monitoring within the Water Framework Directive. We developed a hierarchical object-based image classification model with multi-seasonal Sentinel-2 imagery and suitable spectral indices in order to map the aquatic vegetation in a Mediterranean oligotrophic/mesotrophic deep lake; we then applied the model to another lake with similar abiotic and biotic characteristics. Field data from a survey of aquatic macrophytes, undertaken on the same dates as EO data, were used within the accuracy assessment. The aquatic vegetation was discerned into three classes: emergent, floating, and submerged aquatic vegetation. Geographic object-based image analysis (GEOBIA) proved to be effective in discriminating the three classes in both study areas. Results showed high effectiveness of the classification model in terms of overall accuracy, particularly for the emergent and floating classes. In the case of submerged aquatic vegetation, challenges in their classification prompted us to establish specific criteria for their accurate detection. Overall results showed that GEOBIA based on spectral indices was suitable for mapping aquatic vegetation in oligotrophic/mesotrophic deep lakes. EO data can contribute to large-scale coverage and high-frequency monitoring requirements, being a complementary tool to in situ monitoring.
