The Northwest Fire Science Consortium works to accelerate the awareness, understanding, and adoption of wildland fire science. We connect managers, practitioners, scientists, and local communities and collaboratives working on fire issues on forest and range lands in Washington and Oregon.

Engaging fires before they start: Spatial fire planning for the 21st Century

What will you learn?

New fire management paradigms are emerging that recognize fire is inevitable, and in many cases desirable. During this webinar you will be introduced to a new process for spatial fire planning using tools such as Potential Control Line atlases (PCLs), Quantitative wildfire Risk Assessments (QRAs), and Suppression Difficulty Index (SDI). Chris will demonstrate how these tools can align wildfire management decisions and actions, from the development of strategic wildfire response zones to in situ wildfire response decisions that balance operational success, firefighter safety and values at risk. He will also highlight opportunities to use these tools for allocating limited restoration resources to support wildfire response, including areas where cross-boundary management would be beneficial. By the end of this webinar Chris hopes you will have a better understanding of ongoing efforts to engage wildfires before they start, as a means to help society learn to live with wildfire during this period of rapid environmental change.

A multi-century history of fire regimes along a transect of mixed-conifer forests in central Oregon, U.S.A

Authored by E.K. Heyerdahl; Published 2019

Dry mixed-conifer forests are widespread in the interior Pacific Northwest, but their historical fire regimes are poorly characterized, in particular the relative mix of low- and high-severity fire. We reconstructed a multi-century history of fire from tree rings in dry mixed-conifer forests in central Oregon. These forests are dominated by ponderosa pine (Pinus ponderosa Lawson & C. Lawson), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), and grand fir (Abies grandis (Douglas ex D. Don) Lindl.). Across four, 30-plot grids of ~800 ha covering a mosaic of dry mixed-conifer forest types, we sampled 4065 trees for evidence of both highand low-severity fire. From 1650 to ~1900, all four sites sustained frequent, often extensive, low-severity fires that sometimes included small patches of severe fire (50-150 ha during 18%-28% of fire years). Fire intervals were similar among sites and also among forest types within sites (mean intervals of 14-32 years). To characterize the continuous nature of the variation in fire severity, we computed a plot-based index that captures the relative occurrence of low- and high-severity fire. Our work contributes to the growing understanding of variation in past fire regimes in the complex and dynamic forests of North America’s Interior West.
