Human activity dramatically increases the duration of wildfire seasonBy Fred Bales, CFPS, CFI | April 10, 2017
According to a report published in the journal Proceedings of the National Academy of Sciences, "human-ignited wildfires accounted for 84 percent of all wildfires, tripling the length of the average fire season and accounting for nearly half of the total acreage burned."
The report, "Human-Started Wildfires Expand the Fire Niche Across the United States," provides an in-depth analysis of wildfire trends and the impact that humans have had on the increase in wildfires, the lengthening of the traditional wildfire season, and the huge cost of combating these fires. The report is the result of extensive research, led by the University of Colorado Boulder, into the seasonal extent of wildfires across the U.S. over a 21-year period and is based on a review of 1.5 million wildfires.
Blame humans for added 40,000 wildfires each year
Researchers discovered that from 1992 to 2012, the human-caused fire season added an average of 40,000 wildfires each year to the U.S. wildfire experience. The research also revealed that human-related wildfires accounted for nearly 84 percent of the wildfires.
Human-related wildfires are more prominent in the eastern U.S. and western coastal areas. Conversely, lightning-started wildfires are more prominent in the mountainous regions of the western U.S. A variety of other factors related to human-related wildfires is also discussed in the report, which can be downloaded from the National Academy of Sciences website.
