Effects of Soil Temperature during Fire on Seed Survival in Florida Sand Pine Scrub

Table 5

Maximum temperatures at 0 cm and 2 cm soil depth, and in open and vegetated microsites, during a prescribed fire in sand pine scrub at Archbold Biological Station, Florida. Temperatures were quantified with copper-constantan thermocouples and with temperature-sensitive paints placed on adjacent glass petri dishes.

Depth	Microsite	Maximum Temperature
		Thermocouple	Paint^(a)
0 cm	open	621.7	163.7
0 cm	open	436.2	107.2
0 cm	open	383.5	289.8
0 cm	open	367.8	<37.8
0 cm	vegetated	308.1	260.0
0 cm	vegetated	59.8	287.8
0 cm	vegetated	319.8	232.2
0 cm	vegetated	56.9	162.8
2 cm	open	63.0	<37.8
2 cm	open	90.4	<37.8
2 cm	open	52.0	<37.8
2 cm	open	141.7	<37.8
2 cm	vegetated	218.3	<37.8
2 cm	vegetated	63.0	<37.8
2 cm	vegetated	45.6	<37.8
2 cm	vegetated	43.6	<37.8
