One Tree, Multiple "Jurisdictions": North American Experiences with Exotic Invasive Pests Managed at Local, Municipal, and Federal Levels

Summary

Exotic invasive pests can cause significant destruction to individual trees and entire populations.  When managing such problems on a residential tree-by-tree basis the goals, objectives, and decisions may look vastly different than when compared to managing thousands or millions of trees.  Simply put, different stakeholders take different approaches, and frequently a single tree may have multiple entities with “jurisdiction” over it.  In North America three such pests provide excellent examples of this:  the Asian Longhorned Beetle, the Emerald Ash Borer, and the Mountain Pine Beetle.
