“It was sonic warfare”

In Can the tree whisperer save our forests from the pine beetle?, an edited excerpt from his new book, Calgarian author Andrew Nikiforuk explores how David Dunn may have discovered the fix, for an unprecedented multi-decade beetle outbreak affecting the pinyon tree forests of the South-West.

Specifically, through an innovative idea: acoustic warfare against beetles. The results may change the entire field of pest control. “We altered beetle behavior by playing back their own sound” explains Dunn. “We managed to turn them into cannibals. We created unprecedented behaviors.

The excerpt also touches on how some trees make their own “sad” music in response and the effects of nonlinear change.
