Vascular Flora of the Sandy Bottom Wetland Preserve, Buncombe County, North Carolina

Author : Amy E. Boyd

Additional Authors : Adele Preusser

ABSTRACT Southern Appalachian mountain wetlands, especially mountain bogs and swamp forest-bog complexes, are among the most imperiled ecosystems in the southern USA. The Sandy Bottom Wetland Preserve encompasses approximately 10 ha of wetlands along the floodplain of the French Broad River, including swamp forest-bog complex habitat, and is home to several threatened animal species. A …


Stand Dynamics Influence Masting/Radial Growth Relationships in Pinus palustris Mill.

Author : Thomas W. Patterson

Additional Authors : Paul A. Knapp

ABSTRACT Longleaf pine (Pinus palustris) regeneration is dependent on above-average masting (i.e., cone crop) years that occur over 5- to 7-yr cycles. Not understood, however, is how annual cone mast influences radial growth for longleaf pine. Here, we collected tree-ring data from one site in South Carolina and two sites in North Carolina to examine: …


Starting a New Population of Schwalbea americana on a Longleaf Pine Restoration Site in South Carolina

Author : Jeff S. Glitzenstein

Additional Authors : Danny J. Gustafson, Johnny P. Stowe, Donna R. Streng, D. Allen Bridgman, Jr., Jennifer M. Fill, Jason T. Ayers,

ABSTRACT A new population of federally endangered Schwalbea americana (American chaffseed) was initiated at the state of South Carolina Department of Natural Resources Woods Bay Heritage Preserve, near Turbeville, South Carolina, in 2013–14. Based on improved survival over time, growth to maturity, evidence of reproduction, and size structure similar to that of a nearby natural …


Cold-Moist Stratification Improves Germination in a Temperate Terrestrial Orchid

Author : Kirsten E. Poff

Additional Authors : Jyotsna Sharma Matt Richards

ABSTRACT Seed dormancy is a common evolutionary adaptation in temperate plant taxa. Dormancy mechanisms can prevent seeds from germinating at inopportune times, such as a cold period. We report the influence of pregermination stratification treatments on in vitro seed germination and seedling development in Platanthera chapmanii, a rare temperate terrestrial orchid native to the southeastern …

Physiological Characteristics of Southern Appalachian High-Elevation Rock Outcrop Herbs on Clear and Cloudy Days

Author : Jonathan L. Horton

Additional Authors : Katherine E. Culatta

ABSTRACT High-elevation species in some Southern Appalachian communities have been shown to be dependent on frequent cloud immersion. However, little is known about the influence of clouds on rare and endemic species native to high-elevation rock outcrops. These outcrops are characterized by shallow soil and high insolation, exposing species to frequent water stress, which might …


Heavy Metal Tolerance and Accumulation in Plants of the Southeastern United States

Author : A. Joseph Pollard

ABSTRACT Heavy metals can be essential micronutrients in trace concentrations but are often toxic at high concentrations. Physiologically stressful concentrations of heavy metals occur in natural, geological outcrops or result from human activities, such as mining and pollution. Although metal toxicity restricts the growth of sensitive species, some plants are more tolerant. The evolution of …
