Ecosystem Benefits of Wildfire vs. Post-Fire Logging Impacts

fire factsheet thumbMost wildfires in montane (mountainous) forests and shrublands of the western United States are ecologically beneficial and needed for the proper function and maintenance of fire-dependent biota. Unfortunately, many decision-makers view fire as “catastrophic” and believe it to be increasing beyond historical bounds. Contrary to popular belief, there is actually a deficit of wildfire acresin most western montane forests as compared to historical times due primarily to fire suppression. Although historical data using comparable tracking metrics are lacking on a subset of the very large fires (“mega-fires”), there has been no significant upward trend in these fires detected in the past 15 years, although longer timelines are needed for meaningful conclusions.
