Has fire frequency changed in the United States over time?

Prescribed Fire June 26, 2013 Print Friendly and PDF

For most of the United States, current fire frequencies are longer than what historically occurred prior to European settlement. In part, this can be attributed to fire suppression and exclusion efforts. This is particularly true for the eastern 2/3 of the nation. There are some areas of the western United States that are experiencing more frequent fire due to exotic annual grass invasion.
