Table 1. Differences (mean ± SE) between forest structure variables collected in unburned and thrice-burned plots.

		Canopy openness (%)	Understory density (un)	Litter depth (cm)
Unburned ( n  = 162)	February	6.54±0.67	3.11±0.12	4.43±0.15
	August	6.55±0.68	3.33±0.15	4.02±0.13
Thrice-burned ( n  = 162)	February	22.07±1.60	0.86±0.12	1.35±0.06
	August	22.15±1.59	0.69±0.08	1.01±0.02
Analysis of Deviance	Month	<0.001	<0.001	<0.001
	Treatment	<0.001	<0.001	<0.001
	Month x Treatment	= 0.001	>0.05	= 0.01

Statistical results are from Analysis of Deviance using chi-square to test significance and based on quasi-Poisson (understory density and litter depth), and quasibinomial errors (proportion of canopy openness).
