They conducted their analysis based on restoration operations in northern Arizona, where the Four Forest Restoration Initiative (4FRI) has been working collaboratively to restore forests. I have visited the area three times since last November and have seen first-hand the enormous restoration work being done there. Here lies the largest contiguous ponderosa pine forest in the world, and untreated areas are thick with small diameter trees that would provide fuel for catastrophic wildfires under the right conditions. As many as 600 or even 900 trees are crowded together per acre, so a lightening strike can start a fire that can spread all too quickly.<\/p>\n<\/div>
