This study investigated the cause of increasing wildfires frequency between 1950 and 2017 using the Historic wildfires geodatabase maintained at Idaho State University’s GIS Training and Research Center. Analysis was conducted using ArcGIS, Microsoft Excel, and R statistical software. ArcGIS was used to query and summarize the tabular data as well as perform various spatial analyses. In addition, Excel and R were used for data visualization and to perform statistical analysis. The study suggests fire frequencies are increasing over time with the line of best fit following an exponential growth curve. Coniferous forests showed a marked increase in fire frequency especially after the year 2000. The study also revealed that 61% of the total area burned since 1950 occurred during the new millennia. In conclusion, wildfire mangers should expect, plan and prepare for more and larger wildfires in the future. Further research is underway to identify the drivers of this change.
