The paper describes some results of investigations into the spread and radiation temperature of burning of fallen birch leaves and pine and cedar needles at different moisture content using the IR imaging technique. The paper presents the exponential functions of the fire front spread speed depending on the moisture content in the fallen leaves and needles. The radiation temperature of the condensed phase burning in the range of 3–12 mm is 800–900 K provided that the radiation coefficient e equals unity.
