From the Rocky Mountain Research Station:
Changing climatic conditions and an abundance of dense, mature pine forests have helped to spur an epidemic of mountain pine beetles larger than any in recorded history. This has raised concerns among many people that the death, desiccation, and decomposition of the overstory could have dramatic and negative consequences for affected ecosystems.
