The Role of Fire-Return Interval and Season of Burn in Snag Dynamics in a South Florida Slash Pine Forest

Fire Ecology

Table 4 With an outlying point removed, variation in density of lightly to moderately decayed snags in a slash pine (Pinus elliottii var. densa) forest in south Florida after experimental burning was unrelated to season of burn (season) or fire-return interval (interval), and was best explained by a null model or a model including only the density of snags prior to treatment.

Model	Δ AIC_c ^a	Akaike weight^b
Null	0	0.86
Baseline	4.3	0.10
Baseline + interval	7.6	0.02
Baseline + season	8.1	0.01
Baseline + interval + season	15.7	0
Baseline + interval + season + interval*season	24.3	0

^a ΔAIC_c is the difference between each model’s AIC_c score and the score for the best model; models with lower AIC_c scores are better supported by the data.
^b Akaike weight provides an estimate of the likelihood that each model is the best model in the candidate set.
