Disturbance and disturbance interactions drive multiple ecosystem processes over multiple spatial and temporal scales. This project investigated the role of frequent, low-severity fire in Pinus ponderosa (ponderosa pine) forests in altering the success of the irruptive insect Dendroctonus ponderosae (mountain pine beetle (MPB)). We first explored the factors controlling constitutive defenses without fire and then studied the impact of low severity on tree defenses.
