To ensure that only legally logged timber, especially from tropical forests, is sold, we develop tests and reference databases with which the origin of wood can be tracked along the entire value chain (in German).
A total of about 3100 soil sample were taken nationwide within the context of the German agricultural soil inventory by Thünen Institute. What takes place on the field and what happens to the soil samples in the laboratory? This video tells us the story.
How do you know how much fish there is in the North Sea? Does climate change affect fish stocks? Scientists at the Thünen Institute of Sea Fisheries answer these and other questions by taking fish and plankton samples every spring and autumn with a research vessel – and have done so for 50 years.
The Thünen Institute maintains three research vessels for marine studies. Differing in size and specialization, these vessels are put into use for very different expeditions. The video introduces the vessels and shows their activities above and under water.
In order to check whether wood has been logged legally, it may be necessary to know not only the species but also the region from which it originates. This is possible with genetic testing. The video shows how it works (in German).
Climate change endangers many forests in Central Europe. The high dynamic of changing growing conditions impede the natural adaptation of forest ecosystems. The international project SUSTREE is aimed at supporting the adaptive ability of major tree species through seed transfer from today allready dry and warm regions.
