A survey of host trees infested with eastern mistletoe (Phoradendron leucarpum, Viscaceae) at General Burnside State Park in Pulaski County, Kentucky, was made in late 2008 and early 2009. It is the only island state park in Kentucky, and consists of 174.0 ha in the middle of Lake Cumberland, adjacent to the city of Burnside. A total of 244 mistletoe-infested trees from nine tree species in eight families were found. Prunus serotina, Juglans nigra, and Ulmus americana were the most common host trees. Mistletoe infestation had a greater occurrence in older, full-crowned canopy trees of open, exposed sunny habitats.

A survey of eastern mistletoe (Phoradendron leucarpum, Viscaceae) occurrence in infested trees and shrubs within the city limits of Berea, Kentucky, was conducted from February to April 2007. Phoradendron leucarpum was found in 2320 host plants among 21 trees species (two introduced exotics, one hybrid, 18 native) and one naturalized shrub. The predominate host tree observed in Berea was Prunus serotina with 920 trees followed by Juglans nigra with 534 trees, Acer saccharinum with 257 trees, and Ulmus americana with 187 trees. Eight new eastern mistletoe-infested hosts documented for Kentucky were Betula populifolia, Crataegus × lavallei, Lonicera maackii, Prunus munsoniana, Pyrus calleryana, Quercus imbricaria, Q. palustris, and Ulmus pumila. Five of these host plants, Betula populifolia, Crataegus × lavallei, Lonicera maackii, Prunus munsoniana, and Pyrus calleryana, were new host records within the continental United States. Berea had the highest incidence of eastern mistletoe and the greatest...
