Assessing the Impacts of Balsam Woolly Adelgid (Adelges Piceae Ratz.) and Anthropogenic Disturbance on the Stand Structure and Mortality of Fraser Fir (Abies Fraseri (Pursh) Poir.) in the Black Mountains, North Carolina
… due to the introduction of the exotic insect, balsam woolly adelgid (BWA) (Adelges piceae). The decline in Fraser fir is particularly concern because it serves as a foundation species within the spruce-fir forests of the Southern Appalachian Mountains. Our objectives for this research were to …

Stand structure, growth, and mortality in southern Appalachian spruce-fir
… with elevation there were increasing levels of balsam woolly adelgid-caused (Adelgid piceae Ratz.) mortality at the Black and Smoky Mountains where there was a greater proportion of standing dead fir than live fir. Unlike these two sites, Fraser fir on Mount Rogers still had escaped major damage …

Evolutionary History and Genetic Conservation of Fraser Fir (Abies fraseri [Pursh] Poir.)
… it has been devastated by the infestation of the balsam woolly adelgid (Adelges piceae Ratz.), an exotic insect from Europe. Fraser fir is a potentially informative and interesting model species for the study of forest tree population genetics and ecology because of (1) the fragmented nature of …
