Fifty-five years of change in a northwest Georgia old-growth forest
Butler et al., 2018
Old-growth forests provide unique insight into historical compositions of forests in the eastern United States. Plots established within a mixed forest community within Marshall Forest in Rome, Georgia, in 1960 (and remeasured in 1989) were reassessed to determine changes in forest composition. The community has experienced approximately 10% increase in basal area since the previous measurement period. However, changes in species importance have occurred. Chestnut oak (Quercus montana), mockernut hickory (Carya tomentosa), white oak (Quercus alba), and flowering dogwood (Cornus florida) have all decreased in importance, while pignut hickory (Carya glabra), winged elm (Ulmus alata), yellow poplar (Liriodendron tulipifera), and red maple (Acer rubrum) have all increased in importance. ...
Forest disturbance history from 'legacy' Pitch Pine (Pinus rigida) at the New River Gorge, West Virginia
Saladyga, 2017 (a)
The mesosphytic forests of eastern North America represent a forest region characterized by dramatic 20th century changes in disturbance regimes, notably the exclusion of fire. Tree-ring reconstructions of forest disturbance can inform restoration and management plans by placing these changes into a historical context. This study examined forest disturbance with regard to land use change and drought in the New River Gorge region of West Virginia. I developed a 182-year pitch pine (Pinus rigida) growth chronology (1833–2014) using samples collected from 33 trees along 2 km of south and southwest-facing slopes at Babcock State Park...
Population maintenance of Pinus pungens, Lam. (Table Mountain Pine) after a century without fire
Barden, 2000 (b)
A Table Mountain pine (Pinus pungens Lam.) population on an extremely xeric site in western North Carolina recruited new individuals during each of the 12 decades between 1877 and 1996, despite the absence of fire since 1889. Censuses of the population in 1976, 1986, and 1996 showed that the number of pines > 10 years of age increased by 11% during the two decades. However, the number of pines in the 0-to-9-year age class declined by 92% during the same period...
