Germany | New study confirms decline in insect populations, including in PAs
Compared to a decade ago, today the number of insect species on many areas has decreased by about one third. This is the result of a survey of an international research team led by scientists from the Technical University of Munich (TUM). The loss of species mainly affects grasslands in the vicinity of intensively farmed land -- but also applies to forests and protected areas.
Various studies have already demonstrated that there are far fewer creatures chirping, buzzing, creeping and fluttering in German meadows today than 25 years ago. "Previous studies, however, either focused exclusively on biomass, i.e. the total weight of all insects, or on individual species or species groups. The fact that a large part of all insect groups is actually affected has not been clear so far," says Dr. Sebastian Seibold, a scientist with the Terrestrial Ecology Research Group at TUM.
