Table 3 Quaking aspen regeneration height from burned and unburned transects at four sites in Lassen Volcanic National Park, California, USA. Note: sites are ordered by ascending number of years-since-fire. Burned and unburned regeneration heights were compared with the Wilcoxon rank sum test.

From: Quaking Aspen Regeneration Following Prescribed Fire in Lassen Volcanic National Park, California, USA

		Median height (cm)
Site	Years-since-fire	unburned	burned	P-value (W)	>150 cm (%)	>150 cm density (ha⁻¹)
BUT	1	95.0	33.3	0.33 (0)	0.0	0
GR2	3	72.7	40.3	0.40 (2)	0.0	0
BLK	11	57.7	64.9	0.67 (3)	4.8	333
SL^a	11	5.5	57.2		8.1	282

^a SL was the only site with pre-fire height data, but stems greater than 1.37 m tall were not measured and therefore could not be compared to the burned aspen heights at this site.
