Predicting snag fall in an old-growth forest after fire

Fire Ecology

Table 3 The mean variable importance across 15 model runs for the five most important variables in the most predictive models of the post-fire fall of pre-fire snags ≥ 10 cm DBH

Predictor set	Snag population: pre-fire DBH ≥ 10 cm
Predictor set	Variable	Mean importance
Post-fire	Model A: Neighborhood: 0–3 m; collinearity threshold: r = 0.7
	Post-fire DBH	67.1
	Post-fire snag height	38.1
	Bole scorch	21.2
	Distance-weighted crown injury in 0–3 m circle	14.2
	Post-fire decay class	14.0
Pre-fire	Model B: Neighborhood: 0–15 m; collinearity threshold: r = 0.7
	Pre-fire DBH	64.4
	Pre-fire snag height	27.5
	Species	10.8
	Pre-fire density of live trees ≥ 28 cm DBH in 0–3 m circle	10.3
	Pre-fire basal area of live trees in 0–3 m circle	8.8
