Interception as related to gross precipitation and canopy density was studied in the Utah juniper (Funiperus osteosperma (Torr.) Little) and alligator juniper (F. deppeana Steud.) types on Beaver Creek watershed in north-central Arizona. The canopy camera provided the best index of canopy density. Interception was computed by subtracting stemflow and throughfall from gross precipitation. Stemflow was found to be negligible. Throughfall was predicted with reasonable accuracy for either species by the equation Y = 0.044 + 0.865 (gross precipitation in inches) - 0.216 (canopy density index as a decimal fraction of 1.0000).
