This episode explores the process of compartmentalization of decay in trees, through which trees isolate damaged and infected wood from healthy tissues. The discussion focuses on models like CODIT, which describe the formation of barrier zones and their role in protecting trees from the spread of infection.

The episode delves into the biochemical and physiological processes involved in forming these zones, highlighting how factors such as tree species, type of injury, and season influence the effectiveness of compartmentalization. It also examines the practical implications of these findings for tree care, including pruning techniques and wound management. Lastly, the episode reviews tree responses to various types of injuries and their regenerative capacities.
