The authors tested the theory that frequent, low severity wildfire confers a heightened defense response to ponderosa pine against future bark beetle attack.
The authors found that frequent, low-severity fire events correlate with increased resin duct defenses in ponderosa pine, which increases protection against bark beetle infestation provided the trees suffer only minor injury. This resin production decreases during long fire-free periods.
