Masticated Fuels Research
Fuel loading in masticated areas
While small trees and shrubs can be chipped and sold to generate energy, market conditions for biomass are volatile and removal of this biomass is often not cost effective. Masticated biomass is therefore usually left on the forest floor to protect the soil from erosion and to retain nutrients. The biomass contained within the shrubs, hardwoods, and small conifers can be considerable. Masticated wood is often highly fractured and fragmented, with a high surface area: volume ratio. Size and shape of the individual pieces depends on the specific machinery used and amount of mastication effort (i.e. the amount of time spent per unit area).
We sampled fuels at 10 masticated sites from SW Oregon to the central Sierra Nevada in California, using both a plot-based method and Brown's planar intercept method. Final fuel loading values for fine woody fuels, litter, and duff were from plot data and fuel loading values for large woody fuels were from transect data.
