Mortality was compared among ponderosa pines (Pinus ponderosa) with various degrees of crown damage sustained during fall, spring, and summer prescribed burns. After 5 years, 12% of the trees scorched in the fall had died compared to 26% scorched in the spring, and 29% scorched in the summer. Eighty-five percent of this mortality occurred in trees less than 7 in. dbh. Scorch damage of up to 90% of the crown caused minimal mortality regardless of season. West. J. Appl.
