If you are one of those people who loves the quiet communion of hiking in the high-country forests of Colorado, you'd better get there fast. In three years, those forests may be gone.
The Rocky Mountain News reported this week that every large, mature forest of lodgepole pines in Colorado and southern Wyoming will be dead in three to five years. Some 1.5 million acres of pine forest already have been destroyed since 1996. State and federal foresters call the loss "catastrophic."
What's causing the massive die-off? The root cause appears to be global climate change. Winters are warmer. That allows pine bark beetles to survive. The lodgepoles are less able to defend themselves because they have been stressed by years of drought. As a result, a rice-sized bug is felling vast expanses of forests in Colorado. Similar die-offs are underway elsewhere in the western United States and in Canada.
(Forest management practices -- mainly fire suppression in past years -- also are to blame. Dense vegetation allows the beetles to spread more quickly and older trees are more susceptible to the bug.)
