“…A sufficiently high share of the lake surface (around 30%) should be shallow enough to allow establishment by submerged vegetation (Jeppesen et al, 2017 [ 77 ]). In smaller lakes, the total area has been planted (van de Weyer et al, 2014 [ 99 ]) after a complete fish removal (see also Moss et al, 1996 [ 145 ]). Seagrass investigations demonstrate the advantages to transplant large intact patches rather than dispersed plots (Zhang et al, 2021 [ 82 ]).…”

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.

“…The range of products used is growing and includes engineered materials, commercially available salts, modified local soils, and industrial by-products (Hickey and Gibbs 2009). Substances are also currently being developed to flocculate phytoplankton; modify dissolved oxygen, carbon, and nitrogen concentrations; and to encourage spread of desirable plants through propagule dispersal (Pan et al 2011a, 2011b, van de Weyer et al 2014. Manipulation of benthic bacterial communities through increasing redox status, using materials capable of delivering oxygen microbubbles, has also been used (Pan et al 2012b).…”

The use of geoengineering techniques for phosphorus management offers the promise of greater and quicker chemical and ecological recovery. It can be attractive when used with other restoration measures but should not be considered a panacea. The range of materials being proposed for use as well as the in-lake processes targeted for manipulation continues to grow. With increasing political imperatives to meet regulatory goals for water quality, we recommend a coordinated approach to the scientific understanding, costs, and integration of geoengineering with other approaches to lake management.
