In the 1970's, we were so concerned about negative visitor reactions, we scraped charcoal off the bark on trees that park visitors might see. Today, most visitors know that fire is an integral part of how ecosystems and healthy forests are maintained. The use of fire to restore ecosystem health, perhaps more than any other professional program within the National Park Service, demands that we consult, communicate, and collabo rate in the service of conservation with THE NATIONAL FIRE PLAN every single partner, landowner, and Fire Recycles! concerned citizen.
