Researchers in Germany hope to develop a set of automated sensors that will monitor the abundance and diversity of plants, animals, and fungi with the help of pattern recognition and DNA and chemical analysis.
The mass of insects collected by monitoring traps in the Orbroicher Bruch nature reserve in northwest Germany dropped by 78% in 24 years.
In 1989, the group’s traps in one reserve collected 17,291 hover flies from 143 species. In 2014, at the same locations, they found only 2737 individuals from 104 species.
