How do we actually know how healthy a body of water is? Researchers use biological diversity as a criterion for water quality, among other things. Based on the analysis of different animals that live, for example, in a stream or pond, conclusions can be drawn about the health of the water. If a body of water is particularly healthy, it is also sustainable and can be assessed as worthy of protection.
A new pond was created in the new “Technorama Draussen” park and the Riedbach was revitalized. The aim of the workshop is to examine the health of these two bodies of water. For this purpose, the participants first independently collect random samples from the waters, which are identified and counted in the laboratory using an identification key. These samples are then documented using a table and the biodiversity and health of the water are calculated. The work of various groups makes the biodiversity analysis of the Technorama waters more and more precise.
