Table 2 Relative importance (non-normalized contribution to multiple-R2 from multiple linear regression) of explanatory variables measured at thermocouple locations prior to prescribed burns in longleaf pine forest in southwest Georgia, USA, in May 2016; response variables are prescribed burn average temperature (Tavg), time over 60 °C (>60 °C), and their product (Tavg∙>60 °C). Bold font highlights relative importance values ≥ 0.1

From: Longleaf pine proximity effects on air temperatures and hardwood top-kill from prescribed fire
