Wildfires have been a natural part of the ecosystem since the beginning of time. Fossilized charcoal shows that the first wildfires occurred approximately 419 million years ago, soon after the first terrestrial plants evolved. The fact that areas that have frequent wildfires have higher species richness and diversity than unburned old forest areas indicates that fires benefit ecosystems. However, what is good for the forest is not always good for man. Man’s intervention has led to changes in the fires themselves.
New Mexico, like much of the American West, possesses characteristics that make wildfires common. In prehistoric times, the area’s volcanism might have contributed to burns. Now, the most common non-human cause of fires is lightning. Climatic cycles also contribute to the likelihood of wildfires. The heavy rains and deep snows of wet periods create crowded stands of small trees and thick underbrush. These become fuel during periods of drought. This fuel allows the naturally occurring ground fires to become the high-intensity crown fires.
In 1872, Yellowstone, the world's first national park, was established. Fifteen years later, the U. S. Army was assigned the responsibility for its protection.
The Army did not have enough soldiers to fight all of the naturally occurring fires and concentrated on those that were close to roads or human habitation. However, several deadly fires, most notably the 1871 Peshtigo Fire, which killed more than 1,500 people, the 1889 Santiago Canyon Fire, and the 1910 Great Fire made the public believe that all fires were bad. In 1916, the National Park Service took over park management from the Army and fire suppression became the only fire policy for the next fifty years.

In the 1960s, the government changed its policy. It once again recognized fire as a necessary ecological process. Fires were to be allowed to run their courses as long as they could be contained within fire management units and accomplished approved management objectives. Controlled burns were established to reduce the low-level fuels, keeping fires from becoming crown fires. However, fires, both natural and man made, do not always follow government rules.
Jennifer Bohnhoff's next book, Summer of the Bombers, tells the story of a girl who loses everything as a result of a controlled burn that jumps the barriers and races through her town. Scheduled to be published on April 10, it is available to preorder in digital form on Amazon or in paperback directly through the author.
