U.S. Forest Service reports fewer dying trees in Nation’s forests

A recent report from the U.S. Forest Service shows the number of dead trees is on the decline for the second straight year. Most of the reduction is coming from the western states where bark beetles have been killing trees.

The 50 page report called Major Forest Insect and Disease Conditions in the United States: 2011, shows that damage done by various insects like the pine beetle and bark beetle, is on the decline.




In California, the Western Bark Beetles are the major threat to the forest. Western Bark Beetles include: Jeffrey Pine Beetle, Fir Engraver Beetle, Douglas-Fir Beetle, Western Pine Beetle, and Pine Engraver Beetle.

Insect and disease attacks run in cycles, and right now the trend is downward. The history since 1979 indicates a 14 year cycle from high to low. Let’s hope the trend continues down for the next 10 or 12 years.
