Population Dynamics And Ecophysiology Of Fraser Fir (Abies Fraseri) In The High Elevation Forests In The Southern Appalachian Mountains, Steven Douglas Kaylor

Doctoral Dissertations

Dominated by the endemic Fraser fir (Abies fraseri), the high-elevation forests of the Southern Appalachians are one of the most endangered ecosystems in the United States, and the future of these forests remains uncertain. Fraser fir is showing signs of decline in health and increased mortality throughout its range, possibly due to multiple environmental stresses.

Using twenty years of forest monitoring data, this dissertation documents change in forest structure and species composition in high-elevation red spruce-Fraser fir forests in southern Appalachia and generates predictions of future forest change. Additionally, it quantifies physiological measures of carbon fixation, storage and …
