Multi-Scalar Spatial Modeling Of Northern Forest Dynamics: Foundations, Theories, And Applications, Don C. Bragg May 1999

Multi-Scalar Spatial Modeling Of Northern Forest Dynamics: Foundations, Theories, And Applications, Don C. Bragg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation describes the development and analysis of a new forest dynamics model. The NORTHern Woodland Dynamics Simulator (NORTHWDS) was designed to spatially model forest pattern and process for the northern Lake States, and to incorporate multiple spatial scales. While ecologically detailed, this stand table-based model is sufficiently parsimonious to be able to simulate 100s to 1000s of hectares for centuries. Processes like tree regeneration, growth, and mortality, herbaceous and shrubby competition, biogeochemistry, carbon cycling, edge effects, and climatic influences are incorporated in NORTHWDS. Wind disturbance and white-tailed deer browsing were also included …


A Survey Of The General Public Assessing Public Attitudes Toward Animal Damage Control Management Policy, Douglas K. Reiter May 1999

A Survey Of The General Public Assessing Public Attitudes Toward Animal Damage Control Management Policy, Douglas K. Reiter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A mail survey of randomly selected stratified U.S. households assessed general attitudes toward wildlife and specific concerns about wildlife damage management and the federal Animal Damage Control program. Respondents strongly supported federal government's role in ensuring public safety, engaging in public education, and continuing research into nonlethal control methods. Weaker support was found for lethal control of predators and crop depredators, and financial compensation for losses due to wildlife activities was generally opposed. Lethal methods of control were generally considered to be inhumane and nonlethal methods humane. When asked to rank the importance of factors to be considered when selecting …


Utah's Rural Communities: Planning For The Future, Judith A. Kurtzman May 1999

Utah's Rural Communities: Planning For The Future, Judith A. Kurtzman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two of the biggest concerns facing communities in the Intermountain West are the dichotomies of rapid growth and development as opposed to economic decline and stagnation. Numerous strategies have been developed by social and economic scientists to help communities manage the many problems associated with these concerns. One strategy recommended by many researchers and used by numerous communities to stabilize their economies is economic diversification. For many rural communities in Utah, tourism and recreation have been used as part of that diversification effort. Recreation and tourism also play a role in the dichotomies of rapid growth and development by often …


Local Teacher Suggestions And Evaluations Of The Allen And Alice Stokes Nature Center School Group Programs, Jennifer E. Desarro May 1999

Local Teacher Suggestions And Evaluations Of The Allen And Alice Stokes Nature Center School Group Programs, Jennifer E. Desarro

Undergraduate Honors Capstone Projects

Environmental education is becoming more prevalent in school curriculums. The Tbilisi Declaration of 1977 defines environmental education as:

A process aimed at developing a world population that is aware of, and concerned about, the total environment and its associated problems, and which has the knowledge, attitudes, skills, motivation, and commitment to work individually and collectively toward solutions of current problems and the prevention of new ones (Braus and Wood, p.6).

By incorporating more environmental education into elementary and middle school curriculums, the students are becoming more prepared to deal with problems and make educated choices affecting their futures.


Green Canyon Recreation Management Plant, Jesse Evans, Erin Haddock, Todd Tibbetts, Lindsey Topham Jan 1999

Green Canyon Recreation Management Plant, Jesse Evans, Erin Haddock, Todd Tibbetts, Lindsey Topham

Green Canyon Environmental Research Area, Logan Utah

The purpose of this plan is to look at the way Green Canyon is currently being managed and make recommendations for management based on our findings. Prior to this document, a Landscape Assessment was conducted on Green Canyon. This plan incorporates that assessment but focuses on the recreation management of the canyon. We will discuss history, current management, social conditions, purpose and need, as well as methods we used to go about gathering information. The focus is to identify key issues and concerns within the canyon. Management recommendations will be made based on the issues and concerns identified.


Final Environmental Impact Statement: Wasatch Powderbird Guides Permit Renewal, U.S. Forest Service Jan 1999

Final Environmental Impact Statement: Wasatch Powderbird Guides Permit Renewal, U.S. Forest Service

Final environmental Impact Statements (UT)

Analysis of the proposed action and six alternatives considered for the proposed special use permit renewal for Wasatch Powderbird Guides (WPG). WPG operates a guided helicopter skiing concession on the Wasatch-Cache and Uinta National Forests near Salt Lake City, Utah.


Utah Northern Goshawk Project: Environmental Assessment, United States Forest Service Jan 1999

Utah Northern Goshawk Project: Environmental Assessment, United States Forest Service

All U.S. Government Documents (Utah Regional Depository)

This environmental assessment amends the management direction established in current land and resource management plans for the Ashley, Dioxie, Fishlake, Manti-LaSal, Uinta, and Wasatch-Cache National Forests.


Preliminary Analysis Of The Management Situation Summary, Wasatch-Cache National Forest, April 1999, United States Department Of Agriculture, Forest Service Jan 1999

Preliminary Analysis Of The Management Situation Summary, Wasatch-Cache National Forest, April 1999, United States Department Of Agriculture, Forest Service

Forestry

The National Forest Management Act (NFMA) of 1976 (NFMA P.L. 94-588) required each National Forest to develop National Forest Land and Resource Management Plans (Forest Plans), and to update or "revise" them when conditions have significantly changed or at least every 15 years. The Wasatch-Cache National Forest completed its current Forest Plan in 1985 (USDA Forest Service 1985). To comply with NFMA a revision needs to be completed by the end of 2000. In 1997, Congress prohibited expenditure of funds on formal Forest Plan revision. In 1998 prohibitions were lifted for 14 national forests nationwide. The Wasatch-Cache National Forest was …

The Lake States of Michigan, Minnesota, and Wisconsin consist of 49.4 million hectares (112 million acres) of land, 19.8 million hectares (49 million acres) of which are forested, with 6% of those having been removed by law from timber production.
