The authors compared treated and untreated areas after the 2011 Wallow Fire to assess if fuel treatments reduced fire severity and increased ecological resiliency of mixed-conifer forests based on three metrics: high severity patch size, tree survivorship, and nonnative/native herbaceous understory cover post-fire.
The authors found that treated sites prior to the 2011 Wallow Fire resulted in lower tree mortality, smaller patches of high severity, and significantly higher understory herbaceous cover post-fire suggesting that fuel treatments imbue resiliency to uncharacteristically severe fire in mixed conifer ecosystems.
