Title: Masticated Fuel Beds: Custom Fuel Models, Fire Behavior, and Fire Effects

Project Proposal Abstract: In the foothill and mountain regions of California and southern Oregon, dense flammable vegetation and seasonally extreme fire weather present a daunting fuel management challenge. Mastication is an increasingly popular means of treating ladder fuels to reduce wildfire hazard, yet little is known about how masticated fuels in this vegetation type burn. Managers are hampered in making predictions about fire behavior and effects by the lack of information on appropriate model inputs. We propose to thoroughly characterize fuel beds composed of masticated shrubs and small trees at multiple sites in California and southern Oregon, determining fueled depth, bulk density, and the proportion of fuel in different time lag size classes. Because the masticated pieces are often highly fractured and not readily categorized by size, we will additionally estimate ’effective’ size by developing moisture loss curves. Small replicated burns of masticated fuel beds will be conducted under controlled conditions in the laboratory to test differences in above- and below-ground heating among fueled types, fueled compaction levels, and soil moisture levels. Observations of fire behavior will be compared with fire model outputs for existing and custom fuel models, and correction factors developed when warranted. Accuracy of these custom model inputs in predicting fire behavior and effects will be validated by replicated prescribed burns in the field. Products generated from this proposed research will assist managers in estimating fire hazard reduction and developing strategies for prescribed burning that minimizes tree mortality and adverse soil heating impacts.
