Sage‐Grouse Breeding And Late Brood‐Rearing Habitat Guidelines In Utah, David K. Dahlgren, Terry Messmer, Benjamin A. Crabb, Michel Kohl, Shandra Nicole Frey, Eric T. Thacker, Randy T. Larsen, Rick J. Baxter Dec 2019

Sage‐Grouse Breeding And Late Brood‐Rearing Habitat Guidelines In Utah, David K. Dahlgren, Terry Messmer, Benjamin A. Crabb, Michel Kohl, Shandra Nicole Frey, Eric T. Thacker, Randy T. Larsen, Rick J. Baxter

Wildland Resources Faculty Publications

Delineation, protection, and restoration of habitats provide the basis for endangered and threatened species recovery plans. Species recovery plans typically contain guidelines that provide managers with a scientific basis to designate and manage critical habitats. As such, habitat guidelines are best developed using data that capture the full diversity of ecological and environmental conditions that provide habitat across the species’ range. However, when baseline information, which fails to capture habitat diversity, is used to develop guidelines, inconsistencies and problems arise when applying those guidelines to habitats within an ecologically diverse landscape. Greater sage‐grouse (Centrocercus urophasianus; sage‐ grouse) populations in ...


Invasive Phragmites Australis Management Outcomes And Native Plant Recovery Are Context Dependent, Christine B. Rohal, Chad R. Cranney, Eric L. G. Hazelton, Karin M. Kettenring Dec 2019

Invasive Phragmites Australis Management Outcomes And Native Plant Recovery Are Context Dependent, Christine B. Rohal, Chad R. Cranney, Eric L. G. Hazelton, Karin M. Kettenring

Ecology Center Publications

The outcomes of invasive plant removal efforts are influenced by management decisions, but are also contingent on the uncontrolled spatial and temporal context of management areas. Phragmites australis is an aggressive invader that is intensively managed in wetlands across North America. Treatment options have been understudied, and the ecological contingencies of management outcomes are poorly understood. We implemented a 5‐year, multi‐site experiment to evaluate six Phragmites management treatments that varied timing (summer or fall) and types of herbicide (glyphosate or imazapyr) along with mowing, plus a nonherbicide solarization treatment. We evaluated treatments for their influence on Phragmites and ...

Twentieth Century Geomorphic Changes Of The Lower Green River In Canyonlands National Park, Utah: An Investigation Of Timing, Magnitude And Process, Alexander E. Walker, John C. Schmidt, Paul E. Grams Jun 2019

Twentieth Century Geomorphic Changes Of The Lower Green River In Canyonlands National Park, Utah: An Investigation Of Timing, Magnitude And Process, Alexander E. Walker, John C. Schmidt, Paul E. Grams

Watershed Sciences Faculty Publications

Since the early 20th century, the Green River, the longest tributary of the Colorado River, has narrowed, decreasing available riparian and aquatic habitat.

Initially, the widespread establishment of non-native tamarisk was considered to be the primary driver of channel narrowing. An alternative hypothesis postulated that changes in hydrology drove narrowing. Reductions in total streamflow and changes to flow regime occurred due to wide-spread water development, decreased snowmelt flood magnitude, and the increased cyclicity of wet and dry years. The two hypotheses agree on channel narrowing, but each influences modern river management differently. A tamarisk-driven model of narrowing implies that ...

Genetic And Spatial Structuring Of Populus Tremuloides In A Mixed-Species Forest Of Southwestern Utah, Usa, Matthew Bishop, Tucker J. Furniss, Karen E. Mock, Jim A. Lutz

Wildland Resources Faculty Publications

Populus tremuloides Michx. (aspen) is an iconic species of the southwestern United States, where it is known for its extensive clonality. The size of clones and pattern of clonal distribution within and among stands can provide important clues to the species' evolution and ecology, but there are very few studies that have conducted the type of sampling necessary to define these features. We examined the genetic composition and habitat associations of aspen in a mixed-species forest in Cedar Breaks National Monument on the Markagunt Plateau, southwestern Utah. Genetic analysis of 94 stems ≥1 cm diameter at breast height (dbh) selected ...


Predicting Black Bear Activity At Backcountry Campsites In Bryce Canyon National Park, Utah, Wesley G. Larson, Tom Smith Jan 2019

Predicting Black Bear Activity At Backcountry Campsites In Bryce Canyon National Park, Utah, Wesley G. Larson, Tom Smith

Human–Wildlife Interactions

Developing the capacity to predict black bear (Ursus americanus; bear) activity in a diversity of habitats will help conserve bear populations and their habitats and minimize human–bear conflicts. This capacity will be particularly important in areas that provide bear habitat and offer backcountry hiking and camping experiences. Bryce Canyon National Park (BRCA), located on the edge of the Paunsaugunt Plateau in southern Utah, USA, provides important bear habitat and offers visitors 12 backcountry campsites. To effectively manage these areas to minimize human–bear conflicts, park managers will need better information about black bear use of these campsites and other ...


Invasive Phragmites Australis Management In Great Salt Lake Wetlands: Context Dependency And Scale Effects On Vegetation And Seed Banks, Christine B. Rohal Aug 2018

Invasive Phragmites Australis Management In Great Salt Lake Wetlands: Context Dependency And Scale Effects On Vegetation And Seed Banks, Christine B. Rohal

All Graduate Theses and Dissertations

Invasive plants can outcompete native plants, replacing diverse plant communities with monocultures, which can negatively impact the whole ecosystem. One invasive plant, Phragmites australis, has invaded wetlands across North America. In Utah’s Great Salt Lake, it has greatly reduced the area of native plants that are important habitat for migratory birds. Here we describe experiments that assess multiple treatments for Phragmites removal and evaluate the return of native plants after Phragmites management. The treatments were applied to Phragmites patches at two scales (small 1/4-acre plots and large 3-acre plots) and across multiple sites to evaluate how patch size ...

Testing Rearing Diets For A New Invasive Insect Pest In Utah, The Brown Marmorated Stink Bug, James Withers, Loren Linford Jan 2018

Testing Rearing Diets For A New Invasive Insect Pest In Utah, The Brown Marmorated Stink Bug, James Withers, Loren Linford

Research on Capitol Hill

The brown marmorated stink bug (BMSB), Halyomorpha halys, is an invasive insect from Asia. It has caused millions of dollars in damage to fruit, vegetable, ornamental, and field crops since its arrival in North America, and can be a severe nuisance pest when it congregates on human structures to overwinter. The BMSB caused $37 million of apple crop damage in the Mid-Atlantic Region in 2007 to 2010. To study the insect, effective rearing methods are needed. Previous research (Funayama 2004 & 2006; Medal et al. 2012) showed that carrot, raw peanut and soybean increased rearing efficiency. Recent lab experience has found good ...


The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne Jan 2018

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne

Human–Wildlife Interactions

The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities ...

Assessment Of Restoration Seedings On Utah Watershed Restoration Initiative Project Sites, Lacey E. Wilder Dec 2017

Assessment Of Restoration Seedings On Utah Watershed Restoration Initiative Project Sites, Lacey E. Wilder

All Graduate Theses and Dissertations

Overabundance of shrubs poses a major threat to semiarid ecosystems due to degraded understory vegetation. Previous efforts suggest a need for greater understanding of which management practices work best to improve these ecosystems. I sought to develop a better understanding of how the relative performance of commonly seeded species is influenced by three sagebrush removal techniques.

I calculated effect sizes for cover and frequency to estimate relative changes in abundance of 15 common plant species seeded at 63 restoration sites throughout Utah. Shrubs were reduced by fire or mechanical treatment. Effect sizes were assessed using meta-analysis techniques for two post-treatment ...

Seasonal Distribution Of Sage-Grouse In Hamlin Valley, Utah And The Effect Of Fences On Grouse And Avian Predators, Heather Hedden Mcpherron

All Graduate Theses and Dissertations

Greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) numbers have declined throughout the western US and are considered a species of concern in most of the eleven states that are within their range. Sage-grouse habitats have been reduced by approximately 44% since European settlement of the Western United States began (Miller et al. 2011). Loss of habitat has contributed to an average decline of sage-grouse populations by 33% across the range (Connelly and Braun 1997). To expand our knowledge of this species, I monitored 16 radio-collared sage-grouse captured from four leks in Hamlin Valley, Utah, USA in 2011 and 2012 to determine ...
