Proposing Urban Agroforestry Designs For Lincoln, Nebraska: A Model From Berlin, Germany, Noah Johnson

Honors Theses

Given the threat of a worsening climate crisis, there is a strong need for community and ecosystem resilience. Diverse urban agroforestry systems have the potential to accomplish both and meet many of the objectives outlined in the city of Lincoln, Nebraska’s climate action plan. Additionally, Berlin, Germany could provide an effective model for Lincoln in this regard given the city’s extensive history of established urban agroforestry systems. The objective of this study then is to develop a design for an urban agroforestry site modeled on Berlin’s allotment gardens and tailored to Lincoln’s needs. The methods for creating this design included …

Black Bear, Jimmy D. Taylor, James P. Phillips

Wildlife Damage Management Technical Series

The American black bear (Ursus americanus, Figure 1) is a challenging species for wildlife agencies to manage due to its size, intelligence, extensive range, food habits, and adaptability, as well as societal views. In North America alone, agencies receive more than 40,000 complaints about black bear annually. Black bears are known as ‘food-driven’ animals, meaning most conflicts result from a bear’s drive to meet its nutritional needs. Not surprisingly, an overwhelming proportion of conflicts are related to their use of anthropogenic (human) food sources, such as garbage, bird food, and crops. Understanding what drives human-bear conflict is the first part …

Estimating The Total Economic Impact Of Black Bear Peeling In Western Oregon Using Gis And Remi, Jimmy D. Taylor Ii, Anita Morzillo, Aaron M. Anderson

USDA Wildlife Services: Staff Publications

In parts of the Pacific Northwest, black bears emerge from winter dens with depleted fat reserves and feed on mature conifers by stripping bark and consuming sugar-rich sapwood. Peeling by bears affects commercial conifers through direct loss of the tree or degraded log quality at stand harvest. Bears generally peel trees from 15-30 years old in intensively managed forests until preferred foods such as fruits and berries are available, and a single bear can peel several trees per day. Dying trees have a signature red canopy and are detected in annual aerial forest health surveys; however, trees that scar over …

Using the information from the Assessment, we developed strategic goals based …

Relating Fires Affect On Forest Succession And Forest's Effect On Fire Severity In One Burned And Unburned Environment, Tyler Jay Seiboldt

Department of Environmental Studies: Undergraduate Student Theses

Wildfires are a natural part of many forest ecosystems and play a vital role in maintaining their health. Wildfires can have a critical influence on a landscapes plant community through their relative frequency, seasonality, and severity. One of the most heavily influenced regions by wildfire disturbance is the Klamath Mountain region of California. I looked at the affect a wildfires severity had on the Whiskey creek valley within the Whiskeytown National Recreation Area. 8 tree species and 4 flower species were examined on both the burned and unburned regions within this valley nearly a year after the wildfire (May 17-23 …

Science Priorities For Reducing The Threat Of Invasive Species To Sustainable Forestry, Elizabeth A. Chornesky, Ann M. Bartuska, Gregory H. Aplet, Kerry O. Britton, Jane Cummings-Carlson, Frank W. Davis, Jessica Eskow, Doria R. Gordon, Kurt W. Gottschalk, Robert A. Haack, Andrew J. Hansen, Richard N. Mack, Frank J. Rahel, Margaret A. Shannon, Lisa A. Wainger, T. Bently Wigley

USDA Forest Service / UNL Faculty Publications

Invasive species pose a major, yet poorly addressed, threat to sustainable forestry. Here we set forth an interdisciplinary science strategy of research, development, and applications to reduce this threat. To spur action by public and private entities that too often are slow, reluctant, or unable to act, we recommend (a) better integrating invasive species into sustainable forestry frameworks such as the Montréal Process and forest certification programs; (b) developing improved cost estimates to inform choices about international trade and pest suppression efforts; and (c) building distributed information systems that deliver information on risks, identification, and response strategies. To enhance the …

Ec04-1759 Nebraska Register Of Champion Trees 2004, Scott J. Josiah, Christine Meyer

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska is famous for its sports champions, but how about Champion Trees? While Nebraska is considered a "prairie state," trees have always played a prominent role in the quality of life in Nebraska. Native trees were used to build the first pioneer homes, to heat them and protect them from wind. They provide beauty, wildlife, habitat, protection from wind and blowing snow, cleaner air and water and many other benefits.

The Nebraska Champion Tree Register helps to remind us of the contribution trees make to the quality of our lives, and to celebrate the beauty, mystery, inspiration and sense of …

Ec03-1759 Nebraska Register Of Champion Trees 2003, Scott J. Josiah

University of Nebraska-Lincoln Extension: Historical Materials

This register lists the largest trees of over 80 species identified in Nebraska. The name of the owner and nominator, size and location of each tree follow each listing.

Many people across Nebraska have worked hard to make this register as comprehensive and accurate as possible, but the quest to find the largest trees in Nebraska is never over. Champion trees are by nature old, and old trees diminish and die. Larger trees are newly discovered. Thus, this list continually changes as new nominations are submitted.

G03-1512 Establishing Conservation Plantings Of Nut Trees And Shrubs By Direct Seeding Methods, Steven D. Rasmussen, Scott J. Josiah, John Wilson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to plant and raise nut trees and shrubs from seed. Seeding methods, planting design, site preparation and post-planting care are discussed.

Conservation tree and shrub plantings create wildlife habitat, improve water quality, produce marketable nuts, and enhance landscape diversity. Usually, nursery-grown seedlings are used to establish these plantings. However, a number of problems exist when using seedlings, including increased costs and reduced initial tree vigor and survival. Direct seeding of tree and shrub seeds avoids many of these problems, and is a proven, effective means to establish conservation plantings in Nebraska and elsewhere.

G02-1466 Determining The Need To Fertilize Landscape Trees And Shrubs (Revised March 2004), Scott J. Dewald, Steven D. Rasmussen, Charles A. Shapiro, Scott J. Josiah

University of Nebraska-Lincoln Extension: Historical Materials

Most Nebraska soils are fertile enough to support tree and shrub growth without applying fertilizer. However, when woody plants exhibit poor growth or reduced vigor, yet have had adequate moisture and are not experiencing pest problems or other environmental limitations, the proper applicatin of fertilizer may be necessary. This NebGuide explains how to determine if fertilization of established trees and shrubs is required and how to apply the needed amount.

Ec02-1763 How Windbreaks Work, James R. Brandle, Laurie Hodges, Xinhua Zhou

University of Nebraska-Lincoln Extension: Historical Materials

Windbreaks are barriers used to reduce and redirect wind. They usually consist of trees and shrubs but also may be perennial or annual crops and grasses, fences, or other materials. The reduction in wind speed behind a windbreak modifies the environmental conditions or microclimate in this sheltered zone.

G01-1433, Environmental Stresses And Tree Health, Jon S. Wilson, Mark O. Harrell

University of Nebraska-Lincoln Extension: Historical Materials

Environmental stresses cause many health problems in Nebraska trees. Hot and cold temperatures, drying winds, poor soil and root conditions and human activity can damage leaves, bark and roots, and can predispose trees to secondary insect and disease attack. Keeping a tree in good condition through proper maintenance can prevent many environmentally related health problems.

This NebGuide is intended to help tree owners identify tree health problems caused by environmental stresses and provide ways to prevent or reduce damage.

G00-1417 Site Preparation: Key To Successful Conservation Tree Planting In Western Nebraska (Revised February 2002), Doak Nickerson

University of Nebraska-Lincoln Extension: Historical Materials

Establishing a conservation tree planting can be a challenge in semiarid regions like western Nebraska, where annual precipitation of 20 inches or less is the norm. Tree planting failure commonly occurs as a result of poor site preparation coupled with inadequate weed and grass control the first three to five years after planting. Effective site preparation begins the year before planting. The results help young trees survive and grow in several ways. This NebGuide explains when and how to do site preparation for conservation tree planting in Western Nebraska.

G00-1778 Field Windbreaks, James R. Brandle, Laurie Hodges

University of Nebraska-Lincoln Extension: Historical Materials

gricultural producers face many challenges as they try to balance efficient production systems with increasing environmental demands. For these systems to be successful, they must optimize the balance between inputs and final production. Field windbreaks are one way to increase yields while at the same time reducing inputs and improving both environmental quality and production efficiency. Windbreaks reduce wind speed and alter the microclimate in sheltered areas. Field windbreaks reduce wind erosion and the damage to crops caused by wind-blown soil. They improve water use efficiency, reduce risks associated with drought, and manage blowing snow.

Field windbreaks provide positive economic …

G98-1777 Windbreak Renovation, James R. Brandle, Jon Wilson, Craig Stange, Mike Kuhns

University of Nebraska-Lincoln Extension: Historical Materials

Windbreaks are an integral part of many farms and ranches and provide critical protection for farmsteads, livestock and crops. Unfortunately, many windbreaks planted in the 1930s and 1940s are losing their effectiveness due to age, poor health or neglect. In some cases, the windbreak no longer has the necessary density to provide winter protection. In other cases, overcrowding may have reduced the health and vigor of the windbreak, or the windbreak may have been invaded by aggressive sod-forming grasses such as smooth brome, reducing tree growth. Whatever the reason, many older windbreaks need renovation.

G97-1329 How To Manage Your Woodlands For Sustained And Maximum Benefits, Steven D. Rasmussen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to identify possible forest management needs for a woodland in Nebraska and provides management options to maintain healthy trees and meet desired objectives.

Nebraska's forest lands comprise less than 2 percent of the total land base in the state (718,300 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 …

Ec96-1770 Windbreaks For Snow Management, James R. Brandle, H. Doak Nickerson

University of Nebraska-Lincoln Extension: Historical Materials

In areas of high winds and blowing snow, windbreaks can reduce the amount of effort spent on snow management. They can be designed to spread snow across a large area or to confine it to a relatively small storage area. The design of your windbreak will depend on your objective. Field windbreaks designed to distribute snow evenly across a field should be tall and porous. In contrast, windbreaks designed to capture snow and control drifting should have multiple rows with high density. There is no one set design, number of rows, or width of planting that is ideal for every …

Ec96-1768 Windbreak Management, James R. Brandle, Craig Stange

University of Nebraska-Lincoln Extension: Historical Materials

The windbreaks on your farm are an important part of the agricultural landscape. They provide protection for the farmstead, livestock, and crops; provide habitat for wildlife; and contribute to an overall healthy environment for you and your family. They are living systems with youth, maturity, and old age. Like any other living thing they need proper care and management in order to continue to function at their best.

Windbreak management requires an understanding of how your windbreak works. Your goal is to maintain the health and vigor of individual trees and shrubs while maintaining the overall structure of the windbreak …

G96-1304 Windbreak Design (Revised March 2004), Scott J. Josiah, Jon S. Wilson

University of Nebraska-Lincoln Extension: Historical Materials
