The Holocene history and ecological role of fire in forested ecosystems in the southern Appalachians is incompletely known. Determining how often and when fire has affected forest communities requires us to think about fire over time scales that extend beyond those of written fire records. This research is the first to specifically address the spatio-temporal patterns of forest fires in southern Appalachian xeric forests using radiocarbon dating of taxonomically identified soil charcoal as the primary proxy. Forty-eight soil cores were recovered in eight sites established for a companion study of dendrochronological evidence of fire history. The eight sites were located …

Disturbance is a natural part of any forest ecosystem. When disturbance regimes are altered, the forest stands will reflect those changes. Southern Appalachian xeric pine-oak woodlands are one forest type that has experienced such change, primarily in the form of fire suppression. The western side of Great Smoky Mountains National Park contains stands of large trees that escaped earlier intensive logging, show evidence of past fire, and provide an ideal setting for reconstructing stand histories. For three lower-elevation (ca. 500 m ASL) study sites, I used crossdated yellow pine tree-ring chronologies and records from cross-sections taken from living and dead …
