LANDFIRE data was analyzed to quantify and map the areas across Oregon’s dry, fire-prone forests with an overabundance of closed canopy conditions. Such stands are at heightened risk of uncharacteristically large and severe fire, presumably due to fire exclusion and past land management.

While there is broad agreement on treatments within the wildland urban interface around local values at risk, there is less understanding, and hence less agreement, on the full scope, scale, and placement of treatments to address forest resilience at the landscape-scale. The Nature Conservancy in Oregon is using regional analysis of forest departure to promote addressing these uncharacteristic dense conditions in forests with frequent low- and mixed-severity fire regimes (Fire Regime Groups I and III), which we refer to as “Frequent Fire Forests”. Forests with longer fire return intervals have had little or no impact from fire exclusion and are not a focus for this work. this work.
