The NIFC has been tracking wildfires since 1960. While the number of wildfires has actually gone down, the number of acres destroyed has been rising, which experts attribute to hotter, drier conditions that make the blazes harder to contain. In 1981, there were over 249,000 fires, yet only 4.8 million acres were burned. After 1983, the number of wildfires in the United States has stayed below 100,000 every year.
