The rising number of high severity wildfires in California has significant ecological, economic, and health impacts. Many western American forests are adapted to frequent low severity fires. However, the majority of these forests, and particularly the mixed conifer forests of California, are not adapted to high intensity fires and do not possess fire resistance adaptations such as serotinous cones to protect seeds. Consequently, high severity fires have significant negative impacts on California forests, and the absence of low severity fires has considerably altered many fundamental ecosystem processes (Miller et al. 2008). Prior to 1900, low severity fires would burn every 6-15 years. Low severity fires are generally non-lethal, have minimal change to the overstory, and kill mainly small trees. In the past, these fires were started naturally by lightning, or by Native Americans who used low severity fires to manage the forests. …show more content…

The increase in high severity fires is largely due to historical and current fire suppression policies. Federal forest-fire management in the United States began in 1886 following the creation of the national parks, and the passage of the federal Clarke-McNary Act in 1924 began a national fire suppression regime (Stephens and Ruth 2005). Suppression of low severity fires allows surface and ladder fuels to accumulate, contributing to high severity crown fires. Today, 98-99% of all wildland fires are suppressed at less than 0.5 acres in size. Of the 4.5 million acres of land once burned on California, only 6% of this area is burned today. Fire suppression investment is still increasing with 3 billion more dollars invested in fire suppression since 2013. This investment has not prevented increases in the size or frequency of high intensity fires (Stephens 2014). There is currently no comprehensive policy that works to manage fire
