Nonnative Ungulate Impacts On Greater Sage-Grouse Late Brood-Rearing Habitat In The Great Basin, Usa, Mikiah R. Mcginn, Steven L. Petersen, Melissa S. Chelak, Randy T. Larsen, Loreen Allphin, Brock R. Mcmillan, Dennis L. Eggett, Terry A. Messmer Jan 2022

Nonnative Ungulate Impacts On Greater Sage-Grouse Late Brood-Rearing Habitat In The Great Basin, Usa, Mikiah R. Mcginn, Steven L. Petersen, Melissa S. Chelak, Randy T. Larsen, Loreen Allphin, Brock R. Mcmillan, Dennis L. Eggett, Terry A. Messmer

Human–Wildlife Interactions

Domestic livestock grazing is the dominant land use on much of the current range inhabited by greater sage-grouse (Centrocercus urophasianus; sage-grouse) in the western United States. Nonnative feral horses (Equus ferus caballus) also inhabit important sage-grouse seasonal habitats. Overabundant feral horse populations and improper grazing by domestic cattle (Bos taurus) can impact the health of sagebrush (Artemisia spp.) and desert shrub rangeland communities and native wildlife. These impacts to sage-grouse can be exacerbated when they affect late brood-rearing habitat, which provide the forbs and arthropods required to fledge broods. Managers require better information …


Wyoming’S Wild Horse Ranch: History And Description Of A Socio-Ecological Experiment, Alex Sas-Jaworsky, John Derek Scasta Jan 2022

Wyoming’S Wild Horse Ranch: History And Description Of A Socio-Ecological Experiment, Alex Sas-Jaworsky, John Derek Scasta

Human–Wildlife Interactions

The growing population of free-roaming horses (Equus ferus caballus) on western public rangelands has necessitated that federal agencies, such as the Bureau of Land Management (BLM) and U.S. Forest Service, develop novel approaches to curb growth including reproduction management. However, bureaucracy has hindered effective research and application of horse management on public lands and examples on private lands may present new solutions. Here we present the history and current population management strategy for the Wild Horse Ranch (WHR) located in southeastern Wyoming, USA, as an example of an ongoing private entity managing horses. Prior to 1985, this ~6,000-ha …


Foraging Preferences Of Barnacle Geese On Endophytic Tall And Red Fescues, Tuuli-Marjaana Koski, Kari Saikkonen, Tero Klemola, Marjo Helander Jan 2019

Foraging Preferences Of Barnacle Geese On Endophytic Tall And Red Fescues, Tuuli-Marjaana Koski, Kari Saikkonen, Tero Klemola, Marjo Helander

Human–Wildlife Interactions

Many grasses (Poaceae) have symbiotic fungal endophytes, which affect livestock by producing unpalatable or harmful secondary compounds. Less is known about the repelling effects of fungal endophytes on avian grazers despite potential wildlife management implications. Herbivorous goose (Branta spp.) species may become a nuisance in recreational use areas via fecal littering. Planting these areas with grasses that avian grazers avoid may help mitigate this damage. In 2016, we studied the foraging preference of the barnacle geese (B. leucopsis) with endophytic (E+) or endophyte-free (E-) red fescue (Festuca rubra) and/or tall fescue (Schedonorus phoenix) in …


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 nor …
