There were over 56,000 forest fires in the United States during 2012. Millions of trees, which provide beauty, shelter, clean air and drinking water, were destroyed. While trees can be replanted where they were lost, according to the Arbor Day Foundation over one million acres of the country’s national forests are on backlog for planting.
Forest fires can have many different causes, natural or human. They can start from camp fires, burning cigarettes, arson or lightning. The Mustang Complex Fire, for example, was sparked by lightning in July 2012. Consuming over 340,000 acres, this has been the largest fire in the state of Idaho.
Drought and heat add to the potential for fire. The infestation of pine bark beetles can also create dry conditions favorable to fire, turning a forest into a tinderbox, just waiting for a spark. While some fires begin by natural causes, the majority are caused by humans. In 2006, 83 percent of fires were started as a result of human activity and contributed to the burning of 4.4 million acres across the United States, according to the National Interagency Fire Center.
