Tussock Moths


This video is not currently available. We apologize for any inconvenience.

The voracious tussock moth has wiped out thousands of acres of Douglas fir in Oregon. This devastation is really part of the natural cycle of the forest, as long as it doesn’t get out of hand. Scientists have figured out how to control the moth’s populations so that the infestations become beneficial.
