American mistletoe (Phoradendron leucarpum) was observed on 1740 host trees from 12 species in 8 families in Garrard County, Kentucky. Juglans nigra was the predominant host tree; Prunus serotina, Ulmus americana, and Robinia pseudoacacia followed. These four host species accounted for 1560 (89.7%) of the total infested trees. American mistletoe exhibits an aggregated or clumped spatial distribution pattern among host trees, which is characteristic of its life history and avian method of dispersal. In density, the occurrence value was 3.33 infested trees per kilometer traveled.
