Table 1 Microclimatic conditions during four 2016 prescribed fires in longleaf pine forest in southwest Georgia, USA. Treatments include the following silvicultural treatments: g = group selection, r = group selection with reserves, s = single-tree selection, c = control. Time = period when fire burned, RH = relative humidity, T = air temperature, Gust = maximum wind speed recorded per 3 s recording intervals, ROS = rate of spread of fire, and P = number of days since last precipitation

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