Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2011, Leah English, Jennie Popp, Wayne Miller

Research Reports and Research Bulletins

This report is the eighth in a series of reports examining agriculture’s economic contribution on the Arkansas economy. Utilizing data from the United States Bureau of Economic Analysis (BEA), USDA Economic Research Service (ERS), USDA National Agricultural Statistics Service (NASS), and Minnesota IMPLAN Group, Inc. (MIG), the economic contribution of agriculture on the Arkansas economy was estimated for the most recent year available, 2011. The total economic contribution of agriculture (direct, indirect, and induced effects) to value added, employment, and labor income was estimated using the Impact Analysis for Planning System (IMPLAN). The economic contributions of agricultural production and processing …

Elk (Cervus Elaphus) Seasonal Habitat Selection In A Heterogeneous Forest Structure, Jesse N. Popp, David N.C. Mcgeachy, Josef Hamr

Aspen Bibliography

Seasonal habitat selection by the reintroduced Burwash elk population, approximately 30 km south of Sudbury, Ontario, has been analysed in order to assist in the development of future management. Twenty-five adult females were radio-collared and tracked 1–3 times a week for 3 years. The most prominent patterns included selection of intolerant hardwood forests (trembling aspen, white birch, and balsam poplar) during all seasons, while Great Lakes-St. Lawrence pines (white and red pine dominated stands) were used less than expected based on availability for all seasons. The selection patterns are likely associated with seasonal climatic conditions and forage preferences. Because the …

At WKU, “The Spirit Makes the Master”. Our commitment to continuous improvement is clearly reflected in our sustainability efforts. WKU’s commitment to sustainability, whether demonstrated in campus operations or in educational programs, helps to ensure that our graduates are prepared to address the complicated environmental, social and economic issues we face today. They will be able to think critically, solve problems creatively and be engaged citizens. If that’s all we accomplish then we will have achieved great success. But our sustainability commitment pays dividends, as it also leads us to reduce our environmental footprint, practice social responsibility, and conserve natural …

Refining Thresholds In Coupled Fire–Vegetation Models To Improve Management Of Encroaching Woody Plants In Grasslands, Dirac L. Twidwell Jr, Samuel D. Fuhlendorf, Charles A. Taylor Jr, William E. Rogers

Department of Agronomy and Horticulture: Faculty Publications

1. Restoration priorities are typically established without quantitative information on how to overcome the thresholds that preclude successful restoration of desirable ecosystem properties and services. We seek to demonstrate that quantifying ecological thresholds and incorporating them into management-oriented frameworks provide a more comprehensive perspective on how the threshold concept can be applied to achieve restoration goals.

2. As an example, restoration actions have been largely unsuccessful when based on prevailing ecological knowledge of fire-based thresholds in nonresprouting Juniperus woodland. We build on previous threshold-based research and link well-established models from applied fire physics with a widely applied ecological positive feedback …

Wolf Creek Ranch Aspen Monitoring Report, Paul C. Rogers, Allison Jones, James Catlin, James Shuler, Arthur Morris, Michael Kuhns

Aspen Bibliography

In the summer of 2012 we undertook a landscape assessment of aspen forest conditions at Wolf Creek Ranch (WCR) near Kamas, Utah. Using a geographic information system (GIS) coverage of predicted aspen coverage, fifty systematically selected field "plots" were located and mapped with aspen stands around WCR. Seven plots were eventually discarded from our survey due to lack of aspen cover. Volunteer field crews, mostly WCR homeowners, collected aspen data documenting tree sizes, height/age groups, diameters, reproduction, mortality, browse levels, and browse animal use levels.

Aspen Status Report And Recommendation For The Book Cliffs, Paul C. Rogers, Cody M. Mittanck, Ronald J. Ryel

Aspen Bibliography

Regionally quaking aspen (Populus tremuloides Michx.) forests are experiencing numerous impediments to resilience. In the West, recent drought, fire suppression, insects, diseases, climate trends, inappropriate management, and ungulate herbivory are impacting these high biodiversity forests. We conducted a landscape assessment of aspen communities in the Book Cliffs region, Vernal Field Office of the Bureau of Land Management, for the purposes of determining landscape-level status of aspen and making recommendations for future management of these forests. The study area consists of 268 distinct aspen polygons totaling approximately 70 ha (174 acres) of aspen forest surrounded by much larger tracts of …
