How a dead lake came back to life

The Markermeer in the Netherlands was an ecological disaster: almost everything died in the dammed water. With the Marker Wadden nature restoration project, artificial islands had to revive ecosystems. That works. The sandbanks give new dynamics: plants grow that attract birds, which attract other life, insects, spiders, snails, shells, plankton, fish and so on. Cool production in Nature:
"As the landscape matured and vegetation appeared, more species arrived. By 2021, there were 47 breeding bird species, and birds that breed elsewhere are stopping at the islands. Some 60,000 migratory birds sought food and shelter there during the year to July 2021. Scientists have also seen rarer species, such as greater flamingos (Phoenicopterus roseus) and Eurasian spoonbills (Platalea leucorodia), and have found the nests of gull-billed terns (Gelochelidon nilotica), which have not bred in the Netherlands for decades. Perhaps the greatest surprise was spotting a long-tailed duck (Clangula hyemalis), which normally breeds in the Arctic.

By acting as a stepping stone between other marshland areas, Marker Wadden is contributing to the bird biodiversity of the region, the researchers concluded in a research summary presented at a meeting last October.

Scientists led by Bakker and Casper van Leeuwen, also at the Netherlands Institute of Ecology, surveyed Marker Wadden’s fish in 2018 and 2019, finding 19 species — as well as large numbers of fish larvae in several of its shallow habitat types. This is a good sign, says Bakker, because it is hoped that the islands will provide nurseries to boost the local fish population.

Further down the food web, according to van Leeuwen, the shelter provided by the island seems to have boosted productivity at every level, compared with what is going on in the open water. This extends from phytoplankton and zooplankton to insects, spiders and molluscs.

Bakker’s team concluded in 2021 that “the ecosystem seems to be developing towards higher ecological integrity that might increase resilience to future perturbations”.

                          That's the most idea for bringing the dead lake into life to sustain other creatures
