Researchers explain the ecological developments in Lake Stechlin and the latest findings in a new IGB Dossier. In it, they also provide an assessment of which follow-up actions now appear appropriate.

IGB researchers emphasise the great importance of the WFD for sustainable water management.

In a statement released today, the Leibniz Association's Senate recommended continued funding for IGB. This attests to the Institute's very positive development. The Senate thus agrees with the assessment of an international expert panel who conducted a comprehensive review of the Institute’s achievements. Particular emphasis was placed on the structural adjustments and scientific development of the IGB over the past seven years.

A new report provides practical guidance for monitoring the biodiversity and ecological functionality of urban water bodies. 

Researchers at IGB have used long-term data from the Spree River to discover that aquatic plants can compensate for declining water levels in a drier climate. In recent summers, the growth of aquatic plants in the lower part of the Spree has led to an increase in water levels of around 50 to 60 centimetres compared to previous years, thus compensating for the declining discharge. 

Charophytes are extremely beneficial to lakes, improving water quality and biodiversity. However, their abundance was found to decline in many lakes  without clear signs of eutrophication during recent decades. Today, a team from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) in Berlin and the Feldberg-Uckermärkische Seenlandschaft association (FFUS) published recommendations for practitioners on the reintroduction of charophytes.

Since January 2026, Prof. Michael Hupfer has taken over as president of the German Society for Limnology (DGL). The DGL is one of the most important national professional associations for research on inland waters and water management. In this interview, Prof. Hupfer talks about his plans for his new role and explains why transdisciplinary professional societies are so important today.

Researchers at IGB have simulated how summer storms change the ecology of deep, clear lakes in the “LakeLab” at Lake Stechlin. They artificially generated a storm in the LakeLab enclosures, which mixed the water column. This brought nutrients, inorganic carbon, and algae from deeper layers to the surface, triggering a mass development of cyanobacteria—known as blue-green algae blooms.
