The doubling of wildfires since 1970 has been predictable as a result of large scale and indiscriminate control of wild fires in human occupied areas for almost a century. Many tree species depend on fire in order to reproduce. In the mountain regions of northern U.S. and Canada the average frequency of naturally occurring forest fires is 80 years in any given area with the result that the predominant species, lodge pole pine, has a life span of approximately 100 years. Today large areas close to human development are populated by forests that are 100 to 120 years old. Many trees are dyeing from natural senescence and the amount of deadfall in the forest is sufficient to make even a small fire uncontrollable. Physical concentration of deadfall and controlled burns are the only option that give us any control over natures attempt to reestablish the natural balance in these areas.
