Geoecology: a county-level environmental data base for the conterminous United States

Description: The Geoecology Data Base represents a unique compilation of computerized environmental data for research and development needs. Environmental assessment and planning for energy development require rapid access to data at appropriate spatial and temporal scales. In the Environmental Sciences Division (ESD) at Oak Ridge National Laboratory (ORNL), we have developed an integrated data base of diverse environmental resource information from extant sources. Data are stored at the county level of res… more

Remeasurement of permanent vegetation plots in the Great Smoky Mountains National Park, Tennessee, USA, and the implications of climatic changes on vegetation. Environmental Sciences Division publication No. 1111

Description: This report summarizes field work over two summers (1976 and 1977) to relocate, monument and reinventory permanent vegetation plots in the Great Smoky Mountains National Park. These plots were first established by the senior author and R.H. Whittaker in 1959-62. The inventory results are discussed in terms of vegetation changes in high-altitudinal forest ecosystems, in particular the spruce-fir forests, and the factors, climate shift and biotic and abiotic agents, bringing about vegetation chan… more

Role of temperate zone forests in the world carbon cycle: problem definition and research needs

Description: The proceedings of a workshop on carbon uptake and losses from temperate zone forests are presented. The goals of the workshop were to analyze existing data on growth and utilization of the temperate zone forest carbon pool and to identify further research needs in relation to the role of temperate forests in the global carbon cycle. Total standing stock and growth recovery transients were examined for most of the temperate region over a period from pre-settlement times to the present, with emp… more

Sludge application program at the Savannah River Plant

Description: Since 1980 a research program has been conducted at the Savannah River Plant to evaluate the use of domestic sewage sludge to enhance forest productivity. The objectives of the program have been to determine the cost effectiveness and environmental impact of using sewage sludge as a soil conditioner and slow-release fertilizer. The potential impacts of sludge application on nutrient cycling, organic carbon budgets, forest wildlife, and biomass production have been studied. Soil, soil water, gro… more

Effect of acidity on microbial processes in a forest soil

Description: The objective of this study is to obtain comprehensive baseline information on the microbial activity in a forest soil in order to begin an evaluation of the impact of pollutants resulting from energy related activities. Since most of the soils on Long Island, New York, are poorly buffered and may respond to acid precipitation more quickly, it was decided to study the effect of acidity on various microbial processes. A Riverhead sandy loam soil collected from an oak-pine forest with a pH of 4.6… more

Energy sensitivity and variability analysis of Populus hybrid short-rotation plantations in northeastern United States. Final report

Description: Production of biomass by corn-like plantations has been demonstrated by a number of researchers. These forest analogs of agronomic cropping systems have the potential to yield substantially more biomass per unit area than traditional forests. Care is needed in choosing the appropriate sites, species, spacing, and harvesting strategies. Opportunities for increased yields have been suggested for fertilization and irrigation. Utilization of the biomass from these dense plantations for energy was t… more

Can sulfate fluxes in forest canopy throughfall be used to estimate atmospheric sulfur deposition

Description: The flux of sulfate is forest throughfall and stemflow (the sum of which is designated here as TF) may be an indicator of the atmospheric deposition of S, particularly if foliar leaching of internal plant S is small relative to washoff of deposition. Extensive data from 13 forests indicate that annual sulfate fluxes in TF and in atmospheric deposition are very similar, and recent studies with {sup 35}S tracers indicate that leaching is only a few percent of total TF. However, some short-term de… more

Discriminant analysis of some east Tennessee forest herb niches. Environmental Sciences Division Publication No. 752

Description: The purpose of this study was to evaluate the effectiveness of using discriminant analysis in assessing plant niches. As a component of research by the Environmental Research Park Project at Oak Ridge, Tennessee, five sites were inventoried for herbaceous species. From this inventory, four sympatric species of Galium and seventeen co-occurring herbaceous species were selected for discriminant analysis. The four species of Galium were treated as two data sets: one was composed of information col… more

The impact of changing land use, nitrate deposition and CO sub 2 fertilization on soil carbon storage

Description: This research strives to assess the impact of changing land use, nitrate deposition and CO{sub 2} fertilization on soil carbon storage. Our motivation is that this reservoir is the most likely candidate for the so-called missing carbon sink. We are working on several aspects of this problem by measuring carbon content, nitrogen content and radiocarbon ratios in paired soil samples from neighboring sites, to determine the impact of land use on soil carbon inventories and turnover times. We are a… more
