There were three central goals and accompanying objectives for this project which are listed below. The project accomplishments are provided below each bulleted objective

Radiative Forcing Over The Conterminous United States Due To Contemporary Land Cover Use Change And Sensitivity To Snow And Interannual Albedo Variability, Christoper A. Barnes, David P. Roy

GSCE Faculty Publications

Satellite‐derived land cover land use (LCLU), snow and albedo data, and incoming surface solar radiation reanalysis data were used to study the impact of LCLU change from 1973 to 2000 on surface albedo and radiative forcing for 58 ecoregions covering 69% of the conterminous United States. A net positive surface radiative forcing (i.e., warming) of 0.029 Wm−2 due to LCLU albedo change from 1973 to 2000 was estimated. The forcings for individual ecoregions were similar in magnitude to current global forcing estimates, with the most negative forcing (as low as −0.367 Wm−2) due to the transition to forest and the …

Landscape Architecture & Regional Planning Studio and Student Research and Creative Activity

This studio was based on the Fairmount Greenway that was developed through a series of public meetings with the neighborhood community and with consultants from the firm Crosby, Schlessinger and Smallridge (CSS). The Fairmount Greenway, while drawing its identity from the traditional greenway model is in fact a reinterpretation of an urban greenway. The greenway path follows along both primary and secondary city streets because of the lack of space along the rail right-of-way. The Fairmount Greenway begins at what will be a new station stop at New Market South Bay near Upham’s Corner in northern Dorchester. The greenway follows …

Guide To Woody Plants Of Nebraska, Justin R. Evertson, Kim Todd, David Mooter, Kate Schumacher

Nebraska Forest Service: Publications

Species diversity is the cornerstone of a healthy community forest. In an effort to increase species diversity, this publication provides a nearly complete list of woody plants that can be grown in Nebraska communities. Each plant is keyed to the hardiness zone map on this page to show where it will grow best in Nebraska. It should be noted, however, that many plants need extra care and protection to survive certain climates. Conversely, many plants may do well outside of their recommended zone if the proper microclimate exists.

How To Manage Your Woodlands For Sustained And Maximum Benefits, Steven D. Rasmussen

Nebraska Forest Service: Publications

Nebraska's forest lands comprise less than 2 percent of the total land base in the state (7 18,300 acres). However, on an acre by acre comparison, woodlands provide more associated benefits for society, the environment and our quality of life than most other land uses. Trees provide soil protection from wind and water erosion. Woodlands help protect the quality of adjacent water resources by eliminating contaminates, shading for cooler water temperatures and contributing organic matter for use by aquatic life at all levels. Trees and shrubs also trap snow for spring moisture. Woodlands are necessary areas for many wildlife species …

Since 1991, the U.S. Department of Agriculture (USDA) Forest Service Forest Stewardship Program has assisted over 200,000 landowners in preparing multipurpose management plans for areas encompassing more than 20 million acres of nonindustrial private forest (NIPF). These plans promote the long-term sustainability of private forests by balancing future public needs for forest products with the need for protecting and enhancing watershed productivity, air and water quality, fish and wildlife habitat, and threatened and endangered species.

Conducting A Prescribed Burn And Prescribed Burning Checklist, Jerry D. Volesky, James L. Stubbendieck, Rob B. Mitchell

Nebraska Forest Service: Publications

The interacting forces of climate, fire and grazing formed and maintained the grasslands of the Great Plains of North America. Native Americans were the first to use fire to manipulate plant communities primarily to attract bison to lush regrowth. With the arrival of Europeans, the deliberate setting of fire was greatly curtailed because of the loss of property and potential loss of life associated with wildfires. Today, land managers realize that fire or prescribed burning is an effective tool to manage grassland

Land Use As It Relates To Land Slope, James D. Plourde, Bryan C. Pijanowski

GIS Day

The goal of this project is to analyze the relationship between the slope of land and agricultural land use. The output was analyzed to determine a threshold point at which agriculture practices drop off in relation to higher slope values. Slope of the land is important to agricultural practices because it impacts drainage and net crop primary production. Agricultural land was extracted from the 2001 National Land Cover Dataset using reclassification tools in ArcGIS 9.3. The slope of the contiguous United States was derived from the United States Geological Survey National Elevation Dataset by using the slope tool in the …

Effects Of Experimental Nitrogen Additions On Plant Diversity In An Old-Growth Tropical Forest, Xiankai Lu, Jiangming Mo, Frank S. Gilliam, Guoyi Zhou, Yunting Fang

Biological Sciences Faculty Research

Response of plant biodiversity to increased availability of nitrogen (N) has been investigated in temperate and boreal forests, which are typically N-limited, but little is known in tropical forests. We examined the effects of artificial N additions on plant diversity (species richness, density and cover) of the understory layer in an N saturated old-growth tropical forest in southern China to test the following hypothesis: N additions decrease plant diversity in N saturated tropical forests primarily from N-mediated changes in soil properties. Experimental additions of N were administered at the following levels from July 2003 to July 2008: no addition (Control); …

Traditional Plant Use Of The Raglay In Cãu Gãy Village, Núi Chúa National Park, Alex Greene

Independent Study Project (ISP) Collection

Members of the Raglay community of Cãu Gãy Village were interviewed to determine the extent and nature of their traditional reliance on plants. This community, located in the buffer zone of Núi Chúa National Park, was found to utilize 64 plant species for a wide variety of uses. Botanical specimens and photographs were used to identify 42 plants to species level, 13 to genus level, and 6 to family level, while 3 remained unidentified. For each plant, the Raglay name, local Vietnamese name, use, specific application, and preparation were documented, as well as any details of ritual or commercial significance. …

Modeled Nitrogen Loading To Narragansett Bay: 1850 To 2015, Matthew A. Vadeboncoeur, Steven P. Hamburg, Donald Pryor

Earth Systems Research Center

Nutrient loading to estuaries with heavily populated watersheds can have profound ecological consequences. In evaluating policy options for managing nitrogen (N), it is helpful to understand current and historic spatial loading patterns to the system. We modeled N inputs to Narragansett Bay from 1850 to 2000, using data on population, human waste disposal, livestock, fertilizer, and atmospheric deposition. We found that total N loading to the bay increased 250% from 1850 to 2000, and 80% from 1900 to 2000. Loading to the upper bay increased far more than that to the lower bay, and the most important source shifted from …

Biology Faculty Publications

Much remains to be learned about the biology of mushroom-forming fungi, which are an important source of food, secondary metabolites and industrial enzymes. The wood-degrading fungus Schizophyllum commune is both a genetically tractable model for studying mushroom development and a likely source of enzymes capable of efficient degradation of lignocellulosic biomass. Comparative analyses of its 38.5-megabase genome, which encodes 13,210 predicted genes, reveal the species's unique wood-degrading machinery. One-third of the 471 genes predicted to encode transcription factors are differentially expressed during sexual development of S. commune. Whereas inactivation of one of these, fst4, prevented mushroom formation, inactivation of another, …

Evaluating Tiffs (Toolbox For Lidar Data Filtering And Forest Studies) In Deriving Forest Measurements From Lidar Data, John Chapman, I-Kuai Hung, Jeff Tippen

Faculty Publications

Recent advances in LiDAR (Light Detection and Ranging) technology have allowed for the remote sensing of important forest characteristics to be more reliable and commercially available. Studies have shown that this technology can adequately estimate forest characteristics such as individual tree locations, tree heights, and crown diameters. These values are then used to estimate biophysical properties of forests, such as basal area and timber volume. This study assessed the capability of a commercially available program, Tiffs (Toolbox for Lidar Data Filtering and Forest Studies), to accurately estimate forest characteristics, as compared to data collected at the plot level using traditional …

Meta-Analysis Of Fertilization Experiments Indicates Multiple Limiting Nutrients In Northeastern Deciduous Forests, Matthew A. Vadeboncoeur

Earth Systems Research Center

It is widely accepted that nitrogen limits primary production in temperate forests, although co-limitation by N and P has also been suggested, and on some soils Ca and base cations are in short supply. I conducted a meta-analysis to assess the strength of existing experimental evidence for limitation of primary production by N, P, and Ca in hardwood forests of the northeastern United States and southeastern Canada, using data from 35 fertilization experiments in deciduous forests on glaciated soils across the region.

There is strong evidence for N limitation (formal meta-analysis weighted mean response ratio = 1.51, p < 0.01; simple mean = 1.42, p < 0.001). Forest productivity also tends to increase with additions of P (simple mean = 1.15, p = 0.05) and Ca (simple mean = 1.36 p < 0.001). Across all treatments, 85% of response ratios were positive. Multiple-element additions had larger effects than single elements, but factorial experiments showed little evidence of synergistic effects between nutrient additions. Production responses correlated positively with the rate of N fertilization, but this effect was reduced at high rates of ambient N deposition.
