Table 4 Effect of fire intensity on raking treatment efficacy for sugar pine in Sequoia and Kings Canyon national parks, California, USA. Three-year post-fire mortality was modeled using logistic mixed effects regression. Trees were assigned to a fire intensity category based on percent crown volume scorched. Low intensity = scorch (percent crown volume scorched) = 0% (n = 172), Moderate intensity = scorch between 1% and 79% (n = 181), or High intensity = scorch% >80% (n = 104). Fixed effects in the models were burn unit, raking treatment, and fire intensity category, and an interaction between raking and fire intensity category. Plot was included as a random effect. Estimate is the coefficient from the GLMM, with associated standard error (SE) and P-value.
