Swift environmental action to save trees . . .

. . . er, oops:

Green campaigners called police after discovering an illegal logging site in a nature reserve — only to find the culprits were a gang of beavers. Environmentalists found 20 neatly stacked tree trunks and others marked with notches for felling at a beauty-spot in Subkowy, northern Poland.

[. . .]

A police spokesman said: "The campaigners are feeling pretty stupid. There's nothing more natural than a beaver."

H/T to Radley Balko, who writes that "they may have violated some wetlands regulations, too."
