Something strange is happening in the forests around Chernobyl. More precisely1, it is what is not happening that is the problem. When leaves fall and trees die there, they are not decomposing2 properly.
Scientists visiting the dead forests noticed that the trees were almost unchanged nearly 30 years after the disaster. They also found an unusually thick carpet of fallen leaves. The scientists knew something strange was happening and they decided3 to investigate. They uncovered that the rate of decay for the dead trees and leaves was much slower in the contaminated areas.
It appears that microbes, fungi4 and insects, are suffering from contamination. Usually, when a tree dies in the forest these organisms break it down and turn it into soil. They are essential to the forest ecosystem5. But near Chernobyl the ecosystem has broken down.
