In a pine‐hardwood stand in the Ouachita Mountains of Arkansas, throughfall was strongly correlated with gross rainfall and long‐term mean temperature on the calendar day of the storm, whereas stemflow was closely related to gross rainfall, crown diameter (or basal area at breast height), tree height, and minimum temperature on storm date. Total interception averaged 15.1% of average annual gross rainfall and stemflow 2.4%. Thus, average annual interception loss was 12.7%. Nearly 75% of total stemflow was from hardwoods, which were primarily understory trees.
