Monitoring Whitebark Pine Stand Health In The Central Washington Cascades, Nancy H. Parra, Teresa J. Lorenz, Taza D. Schaming, Alison Scoville
Monitoring Whitebark Pine Stand Health In The Central Washington Cascades, Nancy H. Parra, Teresa J. Lorenz, Taza D. Schaming, Alison Scoville
Student Published Works
Whitebark pine (Pinus albicaulis) plays a vital role in colonizing newly disturbed areas, providing shade for other tree species to germinate, and supplying food for a variety of birds and mammals, such as Clark’s Nutcrackers (Nucifraga columbiana) and grizzly bears (Ursus arctos horribilis). Decline of whitebark pine populations has been attributed to several factors, including white pine blister rust (Cronartium ribicola), mountain pine beetle (Dendroctonus ponderosae) outbreaks, and fire exclusion. In 2009, the U.S. Forest Service began to install permanent plots in whitebark pine stands in Washington and Oregon as …
The Application Of Metacommunity Theory To The Management Of Riverine Ecosystems, Christopher J. Patrick, Kurt E. Anderson, Brown L. Brown, Et Al
The Application Of Metacommunity Theory To The Management Of Riverine Ecosystems, Christopher J. Patrick, Kurt E. Anderson, Brown L. Brown, Et Al
VIMS Articles
River managers strive to use the best available science to sustain biodi versity and ecosystem function. T o achieve this goal requires consideration of processes at different scales. Metacommunity theory describes how multiple species from differ- ent communities potentially interact with local-scale environmental drivers to influ- ence population dynamics and community structure. However, this body of knowledge has only rarely been used to inform management practices for river ecosystems. In this article, we present a conceptual model outlining how the metacommunity processes of local niche sorting and dispersal can influence the outcomes of management interventions and provide a series of …
The Relationship Between Time And Plant Diversity In Prairie Restorations Within The Prairie Corridor On Haines Branch, Elizabeth Park
The Relationship Between Time And Plant Diversity In Prairie Restorations Within The Prairie Corridor On Haines Branch, Elizabeth Park
Department of Environmental Studies: Undergraduate Student Theses
This study focuses on better understanding the relationship between the age of prairie restorations and their plant diversity. The study looks specifically at the prairie restorations within the Prairie Corridor on Haines Branch, located west of Lincoln, Nebraska. The data gathered from these restorations show a positive correlation between age and native plant diversity. This diversity indicates that the restorations are fulfilling their purpose by bringing native prairie plants back to the area. From the data I came to these four conclusions, 1) Because the study only included two restorations greater than 10 years old, it is unclear if the …

Challenges Of Brush Management Treatment Effectiveness In Southern Great Plains, United States, Rheinhardt Scholtz, Samuel D. Fuhlendorf, Daniel R. Uden, Brady W. Allred, Matthew O. Jones, David E. Naugle, Dirac Twidwell
School of Natural Resources: Faculty Publications
Woodland expansion is a global challenge documented under varying degrees of disturbance, climate, and land ownership patterns. In North American rangelands, mechanical and chemical brush management practices and prescribed fire are frequently promoted by agencies and used by private landowners to reduce woody plant cover. We assess the distribution of agency-supported cost sharing of brush management (2000−2017) in the southern Great Plains, United States, and evaluate the longevity of treatment application. We test the general expectation that the current brush management paradigm in the southern Great Plains reduces woody plants and conserves rangeland resources at broad scales. This study represents …

Editorial: Operationalizing The Concepts Of Resilience And Resistance For Managing Ecosystems And Species At Risk, Jeanne C. Chambers, Craig R. Allen, Samuel A. Cushman
School of Natural Resources: Faculty Publications
Ecological resilience is essential for maintaining ecosystem services in an era of rapid global change, but successful attempts to operationalize it for managing ecosystems at risk have been limited. Clear formulation and application of ecological resilience concepts can guide ecosystem management so that it enhances the capacity of ecosystems to resist and recover from disturbances and provides adaptive space for periods of ecological reorganization. As originally defined, ecological resilience measures the amount of perturbation required to change an ecosystem from one set of processes and structures to a different set of processes and structures, or the amount of disturbance that …
Contact Rates With Nesting Birds Before And After Invasive Snake Removal: Estimating The Effects Of Trap-Based Control, Amy A. Yackel Adams, Melia G. Nafus, Page E. Klug, Björn Lardner, M.J. Mazurek, Julie A. Savidge, Robert N. Reed

USDA Wildlife Services: Staff Publications
Invasive predators are responsible for almost 60% of all vertebrate extinctions worldwide with the most vulnerable faunas occurring on islands. The brown treesnake (Boiga irregularis) is a notorious invasive predator that caused the extirpation or extinction of most native forest birds on Guam. The success of avian reintroduction efforts on Guam will depend on whether snake-control techniques sufficiently reduce contact rates between brown treesnakes and reintroduced birds. Mouse-lure traps can successfully reduce brown treesnake populations at local scales. Over a 22-week period both with and without active snake removal, we evaluated snake-trap contact rates for mouse- and bird-lure traps. Bird-lure …

Operationalizing Ecological Resilience Concepts For Managing Species And Ecosystems At Risk, Jeanne C. Chambers, Craig R. Allen, Samuel A. Cushman
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
This review provides an overview and integration of the use of resilience concepts to guide natural resources management actions. We emphasize ecosystems and landscapes and provide examples of the use of these concepts from empirical research in applied ecology. We begin with a discussion of definitions and concepts of ecological resilience and related terms that are applicable to management. We suggest that a resilience-based framework for management facilitates regional planning by providing the ability to locate management actions where they will have the greatest benefits and determine effective management strategies. We review the six key components of a resilience-based framework, …

Fish And Macroinvertebrate Response To Restored Off Channel Habitats On The Lower Platte River, Nebraska, Caleb Uerling
Fish And Macroinvertebrate Response To Restored Off Channel Habitats On The Lower Platte River, Nebraska, Caleb Uerling
School of Natural Resources: Dissertations, Theses, and Student Research
Anthropogenic alterations to large rivers ranging from impoundments to levees have caused many rivers to no longer access the floodplain. The ecological integrity of floodplain rivers depends on the interaction between main-channel and floodplain habitats. Fish communities inhabiting floodplain habitats are often dictated by the type of habitat and conditions within that habitat. As restoration projects are undertaken it is imperative that managers understand how fish and macroinvertebrates respond to these events. We collected fish, macroinvertebrates, and habitat parameters on two restored floodplain habitats on the lower Platte River, Nebraska to answer questions about aquatic community response to floodplain restoration …
Plant Diversity Influences The Structure And Function Of A Restored Prairie And Its Responses To Added Disturbances, Rebecca Bevans
Plant Diversity Influences The Structure And Function Of A Restored Prairie And Its Responses To Added Disturbances, Rebecca Bevans
School of Natural Resources: Dissertations, Theses, and Student Research
As global warming, human conversion of natural landscapes to agricultural uses, and widespread biodiversity losses continue to alter the ecosystems we depend on, an understanding of the relationship between ecosystem structure, composition, and function is needed to maintain valuable ecosystem states and their associated functions. Research testing the limits of an ecosystem’s ability to maintain essential structure and functioning under disturbance conditions can aid in this goal.
In this study, I measured the relationship between plant diversity, community structure and functional traits, and their responses to added disturbances. I added disturbances representing those either caused or intensified by human activity …
Effects Of Habitat Restoration On Soil Retention On Santa Rosa Island, Michael Perez, Kathryn Mceachern, Ken Niessen
Effects Of Habitat Restoration On Soil Retention On Santa Rosa Island, Michael Perez, Kathryn Mceachern, Ken Niessen
STAR Program Research Presentations
Ranching began on Santa Rosa Island in the 1840’s, consequently introducing nonnative megafauna that put novel selective grazing pressures on endemic plant species. Their movement patterns also altered substrate integrity as the land became denuded of any stabilizing vegetation. Dense groves of island oak (Q. tomentella) are known to aid in sediment deposition and retention. The groves also function to collect water during periods of intense fog common to the island. This experiment sought to determine whether sediment is being lost or deposited on a ridge in the middle of the island containing a grove of Q. tomentella …

Irrigation Efficiency Of Santa Rosa Island Cloud Forest Restoration Project, Rebecca Bernard, Kathryn Mceachern, Ken Niessen
STAR Program Research Presentations
Beginning in the 1800s, sheep and cattle ranching have caused significant erosion and devegetation of Santa Rosa Island, Channel Islands National Park. In an effort to contain what little soil is left and rebuild the native chaparral, the Cloud Forest Restoration Project is testing erosion control structures such as wattles, leaf litter fences and silt dams. This summer a drip irrigation system was installed along with fog capturing fences to supply water to native plants transplanted near the erosion control structures. As the project has grown, more irrigation has been added to increase the area available for transplanting. This irrigation …

"Tallgrass prairies are the most endangered ecosystem in North America” (Helen et al 2013). “Surveys suggest that since European settlement, declines in area of native prairie range as high as 99.9%”(Sampson, Fred and Fritz Knopf 1994). Prairie ecosystem services are abundant and range from mitigating floods to promoting biodiversity. (USDA Forest Service).Given these benefits, restoring prairies and maintaining native areas should be an important conservation priority. Nematodes, the most abundant animal species on earth, have been used as bio-indicators of soil quality (Neher; Todd). To better understand the dynamics of nematode diversity in native and restored prairies we examines whether …
Prairie Restoration: Bridging The Past And The Future, Daryl D. Smith
Prairie Restoration: Bridging The Past And The Future, Daryl D. Smith
The Prairie Naturalist
Tallgrass prairie once dominated most of mid-continent North America. Conversion of this prairie to cropland was rapid and extensive. Today, it is the most decimated ecosystem in North America with less than two percent remaining. Prairie reconstruction began at the University of Wisconsin Arboretum in the 1930s. Thirty years later, exemplary initiatives by a group of highly motivated restorationists in Illinois and Iowa became a part of the legacy of restoration ecology. Their work generated widespread public interest in prairie restoration and initiated the ongoing biennial North American Prairie Conference. Since then, practitioners have made significant advances in reconstruction and …

Closing The Knowing-Doing Gap In Invasive Plant Management: Accessibility And Interdisciplinarity Of Scientific Research, Virginia Matzek, Justin Covino, Jennifer L. Funk, Martin Saunders
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Like many conservation disciplines, invasion biology may suffer from a knowing-doing gap, where scientific research fails to inform management actions. We surveyed California resource managers to evaluate engagement with scientific research and to identify research priorities. We examined managers' access to information, judgment of the usefulness of existing research, ability to generate scientific information, and priorities for future research. We found that practitioners rely on their own experience, and largely do not read the peer-reviewed literature, which they regard as only moderately useful. Less than half of managers who do research carry out experiments conforming to the norms of hypothesis …

Benthic Macroinvertebrate Response To The Restoration Of A Hypereutrophic Midwestern Reservoir, Jennifer L. Swanson
Benthic Macroinvertebrate Response To The Restoration Of A Hypereutrophic Midwestern Reservoir, Jennifer L. Swanson
School of Natural Resources: Dissertations, Theses, and Student Research
Eutrophication has been the most challenging global threat to the quality of our freshwater resources (Likens, 2010). Reversing the effects of eutrophication can be difficult and takes a great deal of time and money. A hypereutrophic Midwestern reservoir underwent a restoration from 2000-2002, which added a sediment basin at the inlet, three islands, five rock jetties, and the removal of rough fish. The primary objective of this study was to determine changes in the benthic macroinvertebrate community in response to the restoration. Water quality and benthic macroinvertebrate samples were collected once per month in June, July, August, and September in …
