Description: The use of mechanical mastication to treat non-merchantable fuels is becoming increasingly popular, but loadings and other characteristics of masticated fuel beds are unknown. Surveys of eight recently masticated sites in northern California and southwestern Oregon indicate that significant site level differences were detected for 1 hr and 10 hr time-lag classes and total woody fuel loading (P < 0.0001). The majority of the total woody fuel loading occurred in the 10 hr time-lag class (76.9 ± 14.1 percent) at all 10 sites. At one particular site, planar intercept estimates of woody fuel loading were 181.7 (± 20.3) % higher than estimates using a plot-based method. When the actual average squared quadratic mean diameter values (1 hr = 0.06 cm2, 10 hr = 1.09 cm2 and 100 hr = 11.8 cm2) were used, woody fuel loading estimates between the two methods did not differ statistically. Across sites, fuel depth was not a significant predictor of fuel loading (R2 = 0.24, P = 0.22). However, a significant relationship between fuel depth and loading was found at the individual site level, except for one site (WFR). Species masticated, mastication machinery used, and operator experience are some of the potential reasons why the depth to loading relationship differed among sites.
