Fire Ecology

Table 2 Heat delivery during burn treatment application by month, treatment, and longleaf pine seedling size class in South Carolina, USA, in 2013. There were no significant interactions among any of the independent variables in the model; the same superscript letter within a column and effect indicates no significant difference; HB = high-intensity burn; LB = low-intensity burn treatment; Max = peak temperature during burn application; Area60 = area above 60 °C within the time−temperature curve; Dur60 = duration (s) with temperature above 60 °C
