Where did the infestation in Colorado start?
The Mountain Pine Beetle (MPB) is always present somewhere in Colorado. During low periods of the MPB cycle, called endemics, the MPB would normally be found in stressed trees such as those infested with mistletoe, mechanically damaged by construction or soil compaction, or weather impacted (mainly by drought). There is no epicenter from which the state’s infestation started. High periods are called epidemics.
