Puzzle about aquatic plant: Lietzensee blossomed with frizzy spawning herb!

in Lietzensee, a popular waters in Berlin, has spread a striking brown plant for two years in spring, which covers the large areas of the lake. The local association "Citizens for the Lietzensee" turned to the environmental office to obtain information about the mysterious plant. According to the reports, the plant has been identified as the "Krause spawn", which can be found in the water from May to September. However, this plant is not a problem, but is viewed as a sign of improving water quality, according to the Tagesspiegel .

In the past, the Lietzensee suffered from mass developments of poisonous blue -green algae, which significantly impaired the ecosystem by reducing the depth of vision and disabling the growth of underwater plants. Thanks to extensive renovation measures that have been carried out in recent years, these problematic algae has largely disappeared. The return of underwater plants, such as spawwood, could have positive effects on the water quality and the ecological balance of the Lietzensee, as is determined by the environmental office.

monthly monitoring and ecological importance

The capture and evaluation of the water status and the development of the underwater plants are carried out monthly by the environmental agency. These regular analyzes are crucial to monitor the health of the ecosystem and to identify potential challenges in good time.
The fragrance of spawn is expected to die after the flowering period and decrease to the bottom of the lake. This is a normal part of the life cycle of the plant and also plays a role in the nutrient cycle of the water.

The role of aquatic ecosystems is of central importance for understanding the environment. According to the UFZ , sweet waters are hotspots of biodiversity and habitats for over 10% of all known animal species. Algae, which only make up 1% of the global plant biomass, do impressive 45% of global primary production. These dynamics show how important good water quality is for the entire ecosystem.

The optimization of water quality in water, such as the Lietzensee, contributes not only to relax and leisure activities, but also for biological self -cleaning and fishing. It is crucial that municipalities and environmental authorities work together to support and promote such positive developments.
