An analysis of throughfall and stemflow in mixed oak stands

Net rainfall was studied under immature stands of mixed oak in southern New England. Throughfall did not differ significantly between stands. Stemflow was measured from all trees on one‐fortieth‐acre plots. Although yields varied greatly between plots, plot sampling of stemflow within 15% error tolerance was considered practical in most mixed oak stands. Both average dbh of dominant and codominant trees on stemflow plots and plot basal area showed high positive correlations with stemflow. Analysis of individual stems showed species and dbh highly correlated with stemflow. Black oaks yielded more stemflow than white oaks. The only storm characteristic significantly correlated with stemflow was storm size. Stemflow was greater during the dormant season. Copyright 1970 by the American Geophysical Union
