Pre-Columbian Native American Use of Fire on Southern Appalachian Landscapes

چکیده
Fire suppression in the southern Appalachians is widely considered responsible for decreased regeneration in oak ( Quercus ) and fire-adapted species such as table mountain pine ( Pinus rigida ) and pitch pine ( Pinus pungens ) (Barden & Woods 1976; Harmon 1982; Abrams 1992). How fire-adapted species survived in the southern Appalachian highlands in pre-Columbian times is an enigma; lightning-set fires are very infrequent (Harmon 1982; Bratton & Meier 1995) in this region of high annual precipitation. Barden and Woods (1976), Harmon (1982), and Abrams (1992) have speculated that in preColumbian times, Native American use of fire may have been important in the eastern deciduous forest region, but no published studies have documented that the use of fire by prehistoric Native Americans affected the composition of southern Appalachian vegetation. We evaluated the importance of pre-Columbian human impacts on vegetation of the southern Appalachian highlands by comparing the fossil pollen and charcoalparticle record preserved in peat deposited during the past 3900 calendar years in Horse Cove Bog, Highlands, North Carolina, with the archaeological record. We examined the implications of our findings for conserving biodiversity and maintaining landscape heterogeneity using prescribed burning.

Fire history, related to climate and land use in three southern Appalachian landscapes in the eastern United States.
Fire-maintained ecosystems and associated species are becoming increasingly rare in the southern Appalachian Mountains because of fire suppression policies implemented in the early 20th century. Restoration of these communities through prescribed fire has been hindered by a lack of information on historical fire regimes. To characterize past fire regimes, we collected and absolutely dated the t...
متن کاملModeling the Effects of Fire on the Long-Term Dynamics and Restoration of Yellow Pine and Oak Forests in the Southern Appalachian Mountains
We used LANDIS, a model of forest disturbance and succession, to simulate successional dynamics of forests in the southern Appalachian Mountains. The simulated environments are based on the Great Smoky Mountains landscapes studied by Whittaker. We focused on the consequences of two contrasting disturbance regimes—fire exclusion versus frequent burning—for the Yellow pine (Pinus L., subgenus Dip...
متن کاملFire-free land use in pre-1492 Amazonian savannas.
The nature and scale of pre-Columbian land use and the consequences of the 1492 "Columbian Encounter" (CE) on Amazonia are among the more debated topics in New World archaeology and paleoecology. However, pre-Columbian human impact in Amazonian savannas remains poorly understood. Most paleoecological studies have been conducted in neotropical forest contexts. Of studies done in Amazonian savann...
متن کاملEnvironmental impact of geometric earthwork construction in pre-Columbian Amazonia.
There is considerable controversy over whether pre-Columbian (pre-A.D. 1492) Amazonia was largely "pristine" and sparsely populated by slash-and-burn agriculturists, or instead a densely populated, domesticated landscape, heavily altered by extensive deforestation and anthropogenic burning. The discovery of hundreds of large geometric earthworks beneath intact rainforest across southern Amazoni...
