  • In this study we compare airborne radionuclide concentrations during prescribed burns at the Savannah River Site (SRS) and a sample of forests in the Southeastern United States. The spatial trends of airborne radionuclide concentrations from prescribed burn areas at SRS are also characterized. Total suspended particulate (TSP) samples were taken at three settings (subsequently termed burn sample populations): during prescribed burns at SRS (n = 34), on nonburn days at SRS (n = 12) and during prescribed burns at five offsite locations in the Southeastern United States (n = 2 per location). Mass concentrations of TSP were calculated and alpha,more » beta and gamma spectroscopy was performed to determine radionuclide activity concentrations. Spatial correlation in radionuclide concentration was assessed and ordinary kriging was used to create continuous surface maps across our study area. Median activity concentrations of natural radionuclides including {sup 40}K, thorium and uranium isotopes (n = 34) were higher in samples from SRS prescribed fires (p < 0.02) compared to offsite locations (n = 10) and nonburn days (n = 12). Median gross beta activity was also higher at SRS (p < 0.0001). Median concentrations of anthropogenic radionuclides did not significantly differ among burn sample populations except for {sup 238}Pu (p = 0.0022) and {sup 239,240}Pu (p = 0.014) with median concentrations of 8.41 x 10{sup -4} and 6.72 x 10{sup -5} pCi m{sup -3} at SRS compared to 1.55 x 10{sup -4} and -7.07 x 10{sup -6} pCi m{sup -3} (nonburn days) and 1.46 x 10{sup -4} and 2.78 x 10{sup -6} pCi m{sup 3} (offsite burns) respectively. Results from our spatial analysis found that only {sup 40}K demonstrated significant spatial correlation (X{sup 2} = 15.48, p = 0.0004) and spatial trends do not appear to directly link areas with higher activity concentrations with SRS facilities.« less
  • Summary maps presented in this paper depict the current distribution patterns of aboveground woody biomass and carbon content of commercial forests in the southeastern United States. Contour maps of dominance of 10 important southeastern tree taxa are included. These maps were compiled from growing-stock volume data available from the Continuous Forest Inventories (CFI) of the United States Department of Agriculture (USDA) Forest Service, Southern and Southeastern Forest Experiment Stations. The maps of woody biomass and carbon establish the current patterns for standing crop and carbon storage within forests of the southeastern United States, an area comprising 15% of the temperatemore » forest zone of the earth. The contour maps of tree dominance quantify variation in composition within and between forest types previously mapped only qualitatively by the Forest Service. These dominance maps illustrate the individualistic nature of the distributions in response to gradients of environmental factors and effects of land management practices.« less

  • Periodically flooded forests may have higher rates of aboveground net primary production than upland forests and near-continuously flooded forests, but the benefits of periodic inputs of nutrients and water may be diminished by stresses associated with anaerobic soils or drought. Groundwater table depths were measured and aboveground productivity in floodplain forests of South Carolina and Louisiana. Paired plots on locally dry, intermediate, and wet topographic positions across three hydrologic transects encompassed upland hardwood, bottomland hardwood, and cypress swamp forests. Aboveground net primary production (NPP) on wet plots was significantly lower than on intermediate and dry plots (P {le} 0.02). Theremore » was no significant difference between intermediate and dry plots. In addition, aboveground NPP on intermediate plots was not significantly different from 22 temperate upland forests in the literature. Combining data with data from the literature, aboveground NPP on wet plots was negatively related to MWD. On sites with evidence of hydrologic disturbance the slope of this line was 5 times greater. Conditions of periodic flooding and flowing water do not often lead to high rates of productivity compared with upland forests. However, extensive flooding is nearly always a significant stress on forest productivity, particularly when the flooding regime has been recently perturbed through levee construction or impoundment. The data support a more complex interaction between subsidy and stress factors. 79 refs., 4 figs., 2 tabs.« less
  • Near-record warmth over much of the United States during March 2007 promoted early growth of crops and vegetation. A widespread arctic air outbreak followed in early April, resulting in extensive agricultural losses over much of the south-central and southeastern US. This false spring event also resulted in widespread damage to newly grown tissues of native deciduous forest species, shown by previous researchers to have had measurable effects on the terrestrial carbon cycle. The current study reconstructed the historical occurrence of false springs over most of the southeastern quarter of the conterminous US (32 39 N; 75 98 W) from 1901more » to 2007 using daily maximum and minimum temperature records from 176 stations in the Global Historical Climatology Network database, and enhanced vegetation index (EVI) data derived from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite observations. A false spring index was derived that examined the timing of the start of the growing season (SGS), or leaf emergence, relative to the timing of a potentially damaging last hard freeze (minimum temperature 2.2 C). SGS was modeled for the domain by combining EVI data with ground-based temperature degree day calculations reflecting the rate of springtime warming. No significant area-wide, long-term SGS trend was found; however, over much of a contiguous region stretching from Mississippi eastward to the Carolinas, the timing of the last hard freeze was found to occur significantly later, this change occurring along with increased frequency of false springs. Earlier last hard freeze dates and decreased frequency of false springs were found over much of the northwestern part of the study region, including Arkansas and southern Missouri.« less
