The Environmental Benefits Of Trees On An Urban University Campus, Corinne G. Bassett

Master of Environmental Studies Capstone Projects

The University of Pennsylvania is situated on a rapidly growing and highly urbanized campus that, as of the summer of 2015, contained over 6,000 trees. Trees play an important ecological role within the urban environment, as well as support improved public health and provide aesthetic benefits to cities (Nowak et al. 2008; McPherson et al., 2003). This capstone project used the United States Department of Agriculture Forest Service’s software, i-Tree Eco, to quantify the ecosystem benefits that the University of Pennsylvania urban forest conveys to its community. Field research teams collected data on location and tree canopy size ...

Sink Or Source? Fire And The Forest Carbon Cycle, Christina Frame

JFSP Briefs

As the size and severity of fires in the western U.S. continue to increase, it has become ever more important to understand carbon dynamics in response to fire. Many subalpine forests experience stand-replacing wildfires, and these fires and subsequent recovery can change the amount of carbon released to the atmosphere because subalpine forests store large amounts of carbon. Stand-replacing fires initially convert ecosystems into a net source of carbon as the forest decomposes—a short-term effect (decades) that will likely be important over the next century if fire frequency increases as a result of climate change. Over the long ...

Furniture Manufacturing And Marketing: Eight Strategic Issues For The 21st Century, Steven H. Bullard, C. D. West

Faculty Publications

“Take change by the hand, or it will take you by the throat.” Attributed to Winston Churchill, this brief sentence emphasizes the need to understand and embrace change in general. What important “changes” will impact furniture production and marketing in the 21st century? And what can furniture manufacturers and marketers do to “take change by the hand” today and in the future?

Basic Concepts In Forest Valuation And Investment Analysis: Edition 3.0, Steven H. Bullard, Thomas J. Straka

Faculty Publications

This book was originally intended to supplement lectures in forestry economics at the undergraduate level. It’s currently used for that purpose in ‘Forest Resource Economics’ courses at several universities. The book is also intended, however, to serve as a basic reference for foresters with experience in valuation and investment analysis concepts and methods. It has proven to be a valuable resource in forest valuation and investment analysis workshops for practicing foresters, landowners, and others interested in forestry investments.

Wood Furniture Components: Implementation Of Flow-Line Technology Based On Lean Manufacturing Concepts, W. D. Motsenbocker, P. H. Steele, S. L. Hunter, Steven H. Bullard, A. Schuler

Faculty Publications

This case study is #3 in a series of studies that relate specifically to the development and application of lean manufacturing techniques for the furniture and wood component supplying industries. Case study #3 is an example of how productivity can be increased in a furniture manufacturing organization by using flow-line technology.

This case study provides information about lean manufacturing and how a lean manufacturing system can be implemented, followed by a detailed case study of a wood component manufacturing company’s adoption of a new flow-line technology based on lean manufacturing concepts.

After The Fire, Follow The Nitrogen, Jake Delwiche

JFSP Briefs

Nitrogen availability in soils, streams and associated terrestrial and aquatic vegetation can be infl uenced by both wildfi res and prescribed burns, though typically not to the same degree. Extensive research was done on postfire nitrogen dynamics at several mid-altitude coniferous National Forest sites in Idaho. Sites included both wildfi relocations and prescribed burn projects. By measurement of both ammonium (NH4) and nitrate (NO3) levels, researchers documented over time the effects of both high-intensity wildfi res and lower-intensity prescribed burns on nitrogen transformation processes in soil levels, and nitrogen levels in various ecosystem components. Field measurements demonstrated that the soil ...

Investigation Of Compliance With The Ansi Z133.1 - 2006 Safety Standard In The New England Tree Care Industry, Alexandra K. Julius

Masters Theses 1911 - February 2014

Arborists are exposed to many occupational hazards and experience more than three times the overall fatality rate of all U.S. workers. Investigations into fatal incidents lead to a better understanding of industry dangers. However, this knowledge does not extend to how tree workers operate when an injury or fatality does not occur. Current research regarding fatal and nonfatal injuries does not include the accreditation status of the company at which the worker was employed, nor whether certified arborists were on staff. Given the highly skilled nature of the work involved, certification and accreditation might ensure a minimum level of ...

Beech Bark Disease Distribution And Resistance In Michigan And Fungal Endophyte Ecology Of Resistant And Susceptible Beech (Fagus Grandifolia Ehrh.), Rachel E. Griesmer-Zakhar

Dissertations, Master's Theses and Master's Reports - Open

Beech bark disease (BBD), a non-native association of the fungal pathogen Neonectria faginata and the beech scale insect Cryptococcus fagisuga, has dramatically affected American beech within North American forests. To monitor the spread and effects of BBD in Michigan, a network of forest health monitoring plots was established in 2001 following the disease discovery in Ludington State Park (Mason County). Forest health canopy condition and basic forestry measurements including basal area were reassessed on beech trees in these plots in 2011 and 2012. The influence of bark-inhabiting fungal endophytes on BBD resistance was investigated by collecting cambium tissue from apparently ...

A Wildfire Risk Assessment Framework For Land And Resource Management, Joe H. Scott, Matthew P. Thompson, David E. Calkin

USDA Forest Service / UNL Faculty Publications

Wildfires can result in significant, long-lasting impacts to ecological, social, and economic systems. It is necessary, therefore, to identify and understand the risks posed by wildland fire, and to develop cost-effective mitigation strategies accordingly. This report presents a general framework with which to assess wildfire risk and explore mitigation options, and illustrates a process for implementing the framework. Two key strengths of the framework are its flexibility— allowing for a multitude of data sources, modeling techniques, and approaches to measuring risk—and its scalability, with potential application for project, forest, regional, and national planning. The specific risk assessment process we ...

The Forest, The Fire And The Fungi: Studying The Effects Of Prescribed Burning On Mycorrhizal Fungi In Crater Lake National Park, Carol Anna

JFSP Briefs

A first-of-its-kind study, conducted in a forest of old-growth ponderosa pine and white fi r in Oregon’s Crater Lake National Park, explored the relationships among seasonal prescribed burning, an array of soil attributes, and mycorrhizal fungal fruiting patterns. This three-fold approach not only made the study unique, but also enabled researchers to separate the effects of fi re treatment from the effects of soil attributes on fungal fruiting patterns. The study’s site encompassed three different prescribed burn treatments—applied in the early spring, late spring, and fall of 2002—as well as non-burned control plots. Analyzing statistics with ...
