Predicting Infestations of Hemlock Woolly Adelgid ( Adelges tsugae ) in Great Smoky Mountains National Park, Tennessee/North Carolina, USA

by Snider, Scott

Abstract (Summary)
The hemlock woolly adelgid ( Adelges tsugae ) is a non-native, invasive pest killing eastern hemlock ( Tsuga Canadensis ) trees in the eastern United States. The purpose of this research is to evaluate wind and people as dispersal mechanisms and the factors limiting the spread of the adelgid in the Great Smoky Mountains National Park. The results from binary discriminant analysis indicate that people have the biggest influence on spreading HWA, wind was not a significant factor of dispersal, and cold temperatures can limit the range to which it will spread. This information can be applied in the fight against the adelgid because it can help to define a search area with a higher probability of infestation and to define monitoring and treatment standards for these areas.
