During early stages of an outbreak, attacks are limited largely to trees under stress from injury, poor site conditions, fire damage, overcrowding, root disease or old age. Stand-replacing wildfires initiate even-aged stands. Outbreaks of Mountain Pine Beetles can result in large scale losses of pine trees. Milder winters and an abundance of mature pine forests due to many years of wildfire suppression has resulted in an unprecedented northern and eastern expansion of mountain pine beetle populations.
