Mountain Pine Beetle
Mountain pine beetles are the primary biotic disturbance agent in lodgepole pine forests. In epidemic years, they kill millions of acres of trees, creating dead forests that transform landscape ecology. The beetles bore into bark, lay eggs, and introduce fungus that blocks water transport. Trees are overwhelmed by mass attack - thousands of beetles per tree creating damage no defense can resist.
The epidemic cycle is intimately connected to lodgepole pine's own strategy. Dense, even-aged stands created by post-fire regeneration are especially vulnerable - all trees are the same age and size, perfect for beetle population buildup. The fire-dependent forest creates conditions for beetle-dependent disturbance. One disturbance enables another.
Climate change has amplified beetle impacts. Warmer winters allow beetle survival at higher elevations and latitudes; longer summers allow faster breeding. The 2000s beetle epidemic in British Columbia killed 18 million hectares of forest - the largest forest insect outbreak in North American history. The beetle is now moving into previously unaffected areas.
The business insight is that uniform systems are vulnerable to specialized attackers. Lodgepole pine monocultures created by fire management policies became beetle buffets. Companies that create standardized systems - identical stores, identical products, identical processes - become vulnerable to attacks optimized for that standard. Diversity provides insurance that uniformity sacrifices.
