The overarching modelling framework used to quantify relationships between period and fire and the mortality and collapse of large cavity trees.

C is the overall constant in the model; P2, P3 and P4 are the period effects; MF.P2 is the effect of moderate fire in period 2; SF.P2 is the effect of severe fire in period 3, etc.

C为模型的总体常数；P2、P3及P4为周期效应；MF.P2代表第2周期内中度火灾的效应；SF.P2代表第3周期内重度火灾的效应，其余依此类推。
