Coming off of one of the worst fires seasons in the known history of the western states, both managers and citizens are grappling with the complexity of how climate change may alter fire disturbance regimes. Is fire still a natural disturbance in these mountain forests? What relationship does fire have with other disturbances such as drought and bark beetle outbreaks? During this all-day class, we will explore the role of fire in mountain forest ecosystems, typical fire regimes, synergistic disturbances, and predicted changes with climate warming. We will also discuss the history of fire policy ranging from the 10 am policy to the let burn policy, with the caveat of the wildland-urban interface.
