Effects of Restoration Techniques on Breeding Birds in Thermally-Impacted Bottomland Hardwood Forests

Description: Breeding birds were studied in the Pen Branch riparian corridor following site preparation using herbicides and burning to control willow and improve access for planting. Compared with control strips, treated areas supported a greater richness and abundance of breeding birds. The community composition was representative of early successional bottomland forests.

A Comparative Quantitative Study of the Common Elements Found in the Post Oak and Willow

Description: This thesis explores the chemical contents of post oak and willow trees. Samples of each tree are compared to determine the amount of sulfur, phosphorus, potassium, sodium, silicon, iron, aluminum, calcium, magnesium, and manganese in them. Results indicated usefulness of each tree to humans.

Effects of Willow Overstory on Planted Seedlings in a Bottomland Restoration

Description: Various treatments were applied to control overstory willow in the riparian area of the Pen Branch system in order to determine the effects of competition control on seedling survival and growth. Four species, bald cypress, water tupelo, green ash, and swamp chestnut oak, were planted under four levels of willow canopy (intact, 60% removal, 100% removal with herbicide, 100% with mechanical). Species were more important in determining survival than treatment. Bald cypress and green ash survived … more

100-N Area Strontium-90 Treatability Demonstration Project: Phytoextraction Along the 100-N Columbia River Riparian Zone – Field Treatability Study

Description: Strontium-90 (90Sr) is present both in the aquifer near the river and in the vadose and riparian zones of the river’s shore at 100-NR-2. Phytoextraction of 90Sr is being considered as a potential remediation system along the riparian zone of the Columbia River. Phytoextraction would employ coyote willow (Salix exigua). Past studies have shown that willow roots share uptake mechanisms for Sr with Ca, a plant macronutrient as well as no discrimination between Sr and 90Sr. Willow 90Sr concentratio… more

Oreccl - Summary of a National Database on Energy Crop Landbase, Yields, and Costs

Description: The Biofuels Feedstock Development Program at Oak Ridge National Laboratory has developed a county-level database on energy crops-the Oak Ridge Energy Crop County-Level database (RECCL). This database encompasses all U.S. counties and provides easy access to energy crop information specific to a state or county. The database contains predictions of energy crop yields and farmgate prices along with county-level data on the acreage of land suitable for energy crop production. This paper describes… more

The economics of biomass production in the United States

Description: Biomass crops (e.g. poplar, willow, switchgrass) could become important feedstocks for power, liquid fuel, and chemical production. This paper presents estimates of the potential production of biomass in the US under a range of assumptions. Estimates of potential biomass crop yields and production costs from the Department of Energy`s (DOE) Oak Ridge National Laboratories (ORNL) are combined with measures of land rents from USDA`s Conservation Reserve Program (CRP), to estimate a competitive su… more

A National Assessment of Promising Areas for Switchgrass, Hybrid Poplar, or Willow Energy Crop Production

Description: The objective of this paper is to systematically assess the cropland acreage that could support energy crops and the expected farm gate and delivered prices of energy crops. The assessment is based on output from two modeling approaches: (1) the Oak Ridge County-Level Energy Crop (ORECCL) database (1996 version) and (2) the Oak Ridge Integrated Bioenergy Analysis System (ORIBAS). The former provides county-level estimates of suitable acres, yields, and farmgate prices of energy crops (switchgra… more

Riparian Cottonwood Ecosystems and Regulated Flows in Kootenai and Yakima Sub-Basins : Volume I Kootenai River (Overview, Report and Appendices).

Description: Riparian vegetation and especially cottonwood and willow plant communities are dependent on normative flows and especially, spring freshette, to provide conditions for recruitment. These plant communities therefore share much in common with a range of fish species that require natural flow conditions to stimulate reproduction. We applied tools and techniques developed in other areas to assess riparian vegetation in two very different sub-basins within the Columbia Basin. Our objectives were to:… more

Par Pond vegetation status summer 1995 - July survey descriptive summary

Description: A survey of the emergent shoreline aquatic plant, communities began in June 1995, three months after the refilling of Par Pond to approximately 200 feet (61 meters) above mean sea level, and continued with this July survey. Aquatic plant communities, similar to the pre-drawdown Par Pond communities, are becoming reestablished. Beds of maidencane (Panicum hemitomon), lotus (Nelumbo lutea), water lily (Nymphaea odorata), and watershield (Brasenia schreberi) are now extensive and well established.… more

Gender determination in populus

Description: Gender, the expression of maleness or femaleness, in dioecious plants has been associated with changes in morphology, physiology, ecological position, and commercial importance of several species, including members of the Salicaceae family. Various mechanisms have been proposed to explain the expression of gender in Salicaceae, including sex chromosomes, simple Mendelian genes, quantitative genes, environment, and genotype-by-environment interactions. Published reports would favor a genetic bas… more
