Table 3 Mixed effects logistic regression of factors that influenced sugar pine mortality three years post fire in Sequoia and Kings Canyon national parks, California, USA. Fixed effects were burn unit (BurnUnit), dbh, average forest floor fuel depth (Avg.Fuel), raking treatment (Unraked), and the interaction between average forest floor fuel depth and raking treatment. Plot was treated as a random effect. Estimate is the coefficient from the GLMM, with associated standard error (SE) and P-value.
