In this episode of Science of Arboriculture Dr. Dirk Dujesiefken delivers a lecture on the CODIT Principle.  Dr. Dujesiefken addresses the four phases of the defense reaction according to the CODIT principle, and shares his most recent experiments which have interesting implications for how, he suggests, the CODIT model should be expanded.
