Results of the negative binomial regression which examined the impacts of long-term prescribed burning, year, quarter, and wildlife occurrence on the number of ticks encountered per hour that were infected with any bacteria.

	Coefficient (SE)	RR (95% CI)	P
Any Burning (vs. No Burning*)	−2.09 (0.50)	ND	<0.001
Season (Warm [Spring/Summer] vs Cool* [Fall/Winter])	1.54 (0.52)	ND	0.003
Any Burn X Season	−1.58 (0.62)	ND	0.011
Year (2011 vs. 2010*)	0.44 (0.19)	1.55 (1.06, 2.27)	0.024
Constant	−882 (390)	NA	0.024
ln(effort)	1 (exposure)

SE = Standard error. RR = Relative rate. ND = Not determined; RR is not given because it depends on the interacting variable. NA = Not applicable.

*Indicates the reference category.
