Table 5 Mixed effects logistic regression results of factors that influenced the occurrence of stem charring on sugar pine three years post-fire in Sequoia and Kings Canyon national parks, California, USA. Fixed effects in the model were burn unit (BurnUnit), white pine blister rust infection status (InfStatus), raking (Unraked), average forest floor fuel depth (Avg.Fuel), dbh, an interaction between raking and forest floor fuel depth, raking and burn unit, and raking and white pine blister rust infection. Plot was treated as a random effect. Estimate is the coefficient from the GLMM, with associated standard error (SE) and P-value.
