A catastrophic fire reduces a pine forest down to just a few large fire resistant trees. Eventually, the forest is reseeded by these few remaining trees and rebounds to its original population size.

The forest before the fire had less genetic variation and was not as likely to have blister rust resistant individuals. The forest after the fire has less genetic variation and is not as likely to have blister rust resistant individuals The forest before the fire was not as adapted for resistance to blister rust.
