No one can prove that the pesticides are to blame for the decline, however. “There is no data on insecticide levels, especially in nature reserves,” Sorg says. The group has tried to find out what kinds of pesticides are used in fields near the reserves, but that has proved difficult, he says. “We simply don’t know what the drivers are” in the Krefeld data, Goulson says. “It’s not an experiment. It’s an observation of this massive decline. The data themselves are strong. Understanding it and knowing what to do about it is difficult.”
