Restoring Longleaf Pine (Pinus Palustris) In Loblolly Pine (P. Taeda) Stands On The Coastal Plain Of North Carolina, Huifeng Hu

All Dissertations

To support the development of silvicultural protocols for restoring longleaf pine (LLP; Pinus palustris Mill.) and its characteristic herbaceous understory in loblolly pine (LBP; P. taeda L.) stands, a three-year study was conducted on moderately well- and well-drained soils in Onslow County, North Carolina. A replicated field experiment was conducted to test the effects of selected silvicultural treatments on planted LLP seedlings, understory vegetation, and plant resources. Seven canopy treatments included four uniform canopy density treatments defined by target residual basal area [Control, MedBA (9 m2/ha), LowBA (4.5 m2/ha), and Clearcut] and three circular gap treatments defined by area [LG …

Extent Of Coterminous Us Rangelands: Quantifying Implications Of Differing Agency Perspectives, Matthew Clark Reeves, John E. Mitchell

USDA Forest Service / UNL Faculty Publications

Rangeland extent is an important factor for evaluating critical indicators of rangeland sustainability. Rangeland areal extent was determined for the coterminous United States in a geospatial framework by evaluating spatially explicit data from the Landscape Fire and Resource Management Planning Tools (LANDFIRE) project describing historic and current vegetative composition, average height, and average cover through the viewpoints of the Natural Resources Inventory (NRI) administered by the Natural Resources Conservation Service and the Forest Inventory and Analysis (FIA) program administered by the US Forest Service. Three types of rangelands were differentiated using the NRI definition encompassing rangelands, afforested rangelands, and transitory …

Effects Of Experimental Nitrogen Additions On Plant Diversity In Tropical Forests Of Contrasting Disturbance Regimes In Southern China, Xiankai Lu, Jiangming Mo, Frank S. Gilliam, Guirui Yu, Wei Zhang, Yunting Fang, Juan Huang

Biological Sciences Faculty Research

Responses of understory plant diversity to nitrogen (N) additions were investigated in reforested forests of contrasting disturbance regimes in southern China from 2003 to 2008: disturbed forest (withharvesting of understory vegetation and litter) and rehabilitated forest (without harvesting). Experimental additions of N were administered as the following treatments: Control, 50 kg N ha1yr1, and 100kg N ha1yr1. Nitrogen additions did not significantly affect understory plant richness, density,and cover in the disturbed forest. Similarly, no significant response was found for canopy closure in thisforest. In the rehabilitated forest, species richness and density showed no significant response to Nadditions; however, understory cover …

The Influence Of Land Use And Climate Change On Forest Biomass And Composition In Massachusetts, Usa, Jonathan R. Thompson, David R. Foster, Robert M. Scheller, David Kittridge

Environmental Science and Management Faculty Publications and Presentations

Land use and climate change have complex and interacting effects on naturally dynamic forest landscapes. To anticipate and adapt to these changes, it is necessary to understand their individual and aggregate impacts on forest growth and composition. We conducted a simulation experiment to evaluate regional forest change in Massachusetts, USA over the next 50 years (2010–2060). Our objective was to estimate, assuming a linear continuation of recent trends, the relative and interactive influence of continued growth and succession, climate change, forest conversion to developed uses, and timber harvest on live aboveground biomass (AGB) and tree species composition. We examined 20 …

Despotism And Risk Of Infanticide Influence Grizzly Bear Den-Site Selection, Nathan S. Libal, Jerrold L. Belant, Bruce D. Leopold, Guiming Wang, Patricia A. Owen

College of Forest Resources Publications and Scholarship

Given documented social dominance and intraspecific predation in bear populations, the ideal despotic distribution model and sex hypothesis of sexual segregation predict adult female grizzly bears (Ursus arctos) will avoid areas occupied by adult males to reduce risk of infanticide. Under ideal despotic distribution, juveniles should similarly avoid adult males to reduce predation risk. Den-site selection and use is an important component of grizzly bear ecology and may be influenced by multiple factors, including risk from conspecifics. To test the role of predation risk and the sex hypothesis of sexual segregation, we compared adult female (n = 142), adult male …

A Comparative Risk Assessment Framework For Wildland Fire Management: The 2010 Cohesive Strategy Science Report, David E. Calkin, Alan Ager, Matthew P. Thompson, Mark A. Finney, Danny C. Lee, Thomas M. Quigley, Charles W. Mchugh, Karin L. Riley, Julie M. Gilbertson-Day

USDA Forest Service / UNL Faculty Publications

The FLAME Act of 2009 requires the U.S. Department of Agriculture Forest Service and the U.S. Department of Interior to submit to Congress a Cohesive Wildfire Management Strategy. In this report, we explore the general science available for a risk-based approach to fire and fuels management and suggest analyses that may be applied at multiple scales to inform decisionmaking and tradeoff analysis. We discuss scientific strengths and limitations of wildfire risk assessment frameworks, including the benefit of broad scalability as demonstrated by four recent case studies. We further highlight the role of comparative risk assessment, which extends the analysis to …

Classifying And Mapping Diversity In A Species-Poor System: The Mangrove Meta-Community Of Laguna Chacahua National Park, Oaxaca, Mexico, Elizabeth Kay Weisgerber

Master's Theses

ABSTRACT

Classifying and Mapping Diversity in a Species-Poor System: the mangrove meta-community of Laguna Chacahua National Park, Oaxaca, Mexico

by

Elizabeth Kay Weisgerber

Both field transects and imagery grid plots were analyzed with the goal of creating a community classification map for the mangrove forest of Parque Nacional Lagunas de Chacahua. In total, data was collected in 49 sites throughout the park, recording measures such as DBH, basal area, estimated dominance, frequency, cover and relative dominance. Field locations were marked and georeferenced with a GPS and grid plots overlaid on satellite imagery of the park were generated via a random …
