Applications Of Chemical Bird Repellents For Crop And Resource Protection: A Review And Synthesis, Shelagh T. Deliberto, Scott J. Werner
Applications Of Chemical Bird Repellents For Crop And Resource Protection: A Review And Synthesis, Shelagh T. Deliberto, Scott J. Werner
USDA Wildlife Services: Staff Publications
Non-lethal repellents are needed to protect newly planted and ripening crops, to prevent valuable resources from being damaged by some wild birds worldwide. We systematically searched all scientific publications, patents and product registrations to developa current review and synthesis regarding chemical bird repellents for wildlife researchers, ecologists, managers, and conservationists. We then developed a database regarding the testing procedures and repellency results associated with the published and unpublished literature. For this comprehensive database, we developed an ‘index of success,’ or relative efficacy level (e.g. effective in most experiments), associated with each tested bird repellent. We found 345 papers published in …

Choosing and executing a wild pig management strategy is often a considerable challenge for wildlife managers due to the wide variety of potential strategies and stakeholder preferences. Our research aims to understand management preferences for and tolerance of wild pigs among Texas resident hunters within 8 managerial districts of Texas. We applied the Potential for Conflict Index (PCI2) to estimate potential management preference conflicts within each district. From 24,201 questionnaires completed in 2019, we found that, on average, 74% of respondents across all management actions in each district were found to be acceptable. Resident respondents were overall intolerant of wild …
Social Learning Of Avoidance Behaviors: Trap Aversion In Captive Coyotes, Julie Young, Jeffrey T. Schultz, Buck Jolley, Nekol Basili, John P. Draper
Social Learning Of Avoidance Behaviors: Trap Aversion In Captive Coyotes, Julie Young, Jeffrey T. Schultz, Buck Jolley, Nekol Basili, John P. Draper
USDA Wildlife Services: Staff Publications
Social learning can help animals gain knowledge rapidly and may enhance survival. In species that are subjected to capture in foothold traps and then lethally removed, such as the coyote (Canis latrans), learning to avoid traps is critical to survival. Here, we tested social learning of trap avoidance behavior in three experimental scenarios with captive coyotes. In the first experiment, coyotes observed an unfamiliar coyote get captured in a foothold trap (i.e., demonstrator) or did not observe a demonstrator and were therefore naïve to traps. The coyotes that observed a demonstrator showed similar latencies to approach the trap …

USDA Wildlife Services: Staff Publications
Increases in human-wildlife conflicts alongside cultural shifts against lethal control methods are driving the need for alternative wildlife management tools such as fertility control. Contraceptive formulations suitable for oral delivery would permit broader remote application in wildlife species.
This study evaluated the contraceptive effect and immune response to two novel injectable immunocontraceptive formulations targeting the Gonadotropin Releasing Hormone (GnRH): MAF-IMX294 and MAF-IMX294P conjugates, both identified as having potential as oral contraceptives. The study also explored whether in multiparous species immunocontraceptives may either totally prevent reproduction or also affect litter size.
Female rats, chosen as a model species, were given three …
Generalist Bird Exhibits Site-Dependent Resource Selection, Samantha M. Cady, Craig A. Davis, Samuel D. Fuhlendorf, Rheinhardt Scholtz, Daniel R. Uden, Dirac Twidwell
Generalist Bird Exhibits Site-Dependent Resource Selection, Samantha M. Cady, Craig A. Davis, Samuel D. Fuhlendorf, Rheinhardt Scholtz, Daniel R. Uden, Dirac Twidwell
Department of Agronomy and Horticulture: Faculty Publications
Quantifying resource selection (an organism's disproportionate use of available resources) is essential to infer habitat requirements of a species, develop management recommendations, predict species responses to changing conditions, and improve our understanding of the processes that underlie ecological patterns. Because study sites, even within the same region, can differ in both the amount and the arrangement of cover types, our objective was to determine whether proximal sites can yield markedly different resource selection results for a generalist bird, northern bobwhite (Colinus virginianus). We used 5 years of telemetry locations and newly developed land cover data at two, geographically distinct but …

Insufficient funding is a major impediment to conservation efforts around the world. In the United States, a decline in hunting participation threatens sustainability of the “user-pay, public benefit” model that has supported wildlife conservation for nearly 100 years, forcing wildlife management agencies to contemplate alternative funding strategies. We investigated support for potential funding options among diverse college students, a rapidly expanding and politically active voting bloc with a potentially powerful influence on the future of conservation. From 2018 to 2020, we surveyed 17,203 undergraduate students at public universities across 22 states. Students preferred innovative approaches to conservation funding, with 72% …
A Sonic Net Reduces Damage To Sunflower By Blackbirds (Icteridae): Implications For Broad-Scale Agriculture And Crop Establishment, Amanda K. Werrell, Page E. Klug, Romuald N. Lipcius, John P. Swaddle
A Sonic Net Reduces Damage To Sunflower By Blackbirds (Icteridae): Implications For Broad-Scale Agriculture And Crop Establishment, Amanda K. Werrell, Page E. Klug, Romuald N. Lipcius, John P. Swaddle
USDA Wildlife Services: Staff Publications
Blackbirds, such as red-winged blackbirds (Agelaius phoeniceus), are notorious agricultural pests and damage crops at multiple stages of growth. Our aim was to test a novel deterrent, the use of sound designed to mask communication among birds (termed a “Sonic Net”), to deter blackbirds (Icteridae) from target areas of maturing sunflower crops. The Sonic Net masks communication of a target species by delivering “pink noise” that overlaps with the frequencies that the species uses for acoustic communication. If birds cannot hear predators or conspecific warning calls their perceived predation risk increases, and they relocate to an area with …
Conflict, Coexistence, Or Both? Cougar Habitat Selection, Prey Composition, And Mortality In A Multiple-Use Landscape, David C. Stoner, Mark A. Ditmer, Dustin L. Mitchell, Julie K. Young, Michael L. Wolfe
Conflict, Coexistence, Or Both? Cougar Habitat Selection, Prey Composition, And Mortality In A Multiple-Use Landscape, David C. Stoner, Mark A. Ditmer, Dustin L. Mitchell, Julie K. Young, Michael L. Wolfe
USDA Wildlife Services: Staff Publications
Western North America is experiencing remarkable human population growth and land-use change. Irrigation and associated cultivation have led to colonization of urban-wildland interface (UWI) environments by mule deer (Odocoileus hemionus), and consequently, cougars (Puma concolor). In the wake of these changes, human-wildlife conflicts have increased in tandem with questions about long-term species conservation. To address these concerns, we fit 79 cougars with radio-telemetry collars in the Oquirrh Mountains near Salt Lake City, Utah (2002–2010). Our goal was to evaluate variation in cougar habitat selection, diet, and cause-specific mortality in a landscape dominated by urban, military, and industrial activities. We used …

In the state of Colorado, a citizen ballot initiative to reintroduce gray wolves (Canis lupus) is eliciting polarization and conflict among multiple stakeholder and interest groups. Given this complex social landscape, we examined the social context surrounding wolf reintroduction in Colorado as of 2019. We used an online survey of 734 Coloradans representative in terms of age and gender, and we sampled from different regions across the state, to examine public beliefs and attitudes related to wolf reintroduction and various wolf management options. We also conducted a content analysis of media coverage on potential wolf reintroduction in 10 major daily …
Charismatic Predators In Modern Africa: Spotted Hyena (Crocuta Crocuta) And Human Coexistence In The Northern Tuli Game Reserve, Botswana, Jazmin Castillo
Charismatic Predators In Modern Africa: Spotted Hyena (Crocuta Crocuta) And Human Coexistence In The Northern Tuli Game Reserve, Botswana, Jazmin Castillo
School of Natural Resources: Dissertations, Theses, and Student Research
Increasing human populations has led researchers to investigate the impacts of high human population density and its impact on carnivore populations. Spotted hyenas (Crocuta crocuta) hold a unique place in African ecosystems due to being a very successful top predator with an adaptable diet whereas other top predators, like the African lion, are rapidly decreasing in abundance. We investigated past and current spotted hyena abundance within the Northern Tuli Game Reserve to better aid in wildlife management. Spotted hyenas showed no significant difference in the change in population abundance throughout the different years of the study (2008-2016). Spotted …
The Pocatello Supply Depot: A History And Update, Patrick A. Darrow
The Pocatello Supply Depot: A History And Update, Patrick A. Darrow
Proceedings of the Twenty-Ninth Vertebrate Pest Conference (2020)
Since the Pocatello Supply Depot (PSD) was created in 1936, the PSD has gone through many transformation and organizational changes. The most recent of these changes occurred in 2014, when the PSD transitioned from a cooperative service agreement between the U.S. Department of Agriculture (USDA) and the Greater Pocatello Chamber of Commerce, to a fully federal facility within USDA. Despite the many organizational changes, the purpose of the PSD has remained the same. The PSD manufactures and provides specialized wildlife damage management materials and services that are not readily available from commercial sources, for use by USDA Wildlife Services (WS), …
Effect Of Vaccination With A Novel Gnrh-Based Immunocontraceptive On Immune Responses And Fertility In Rats, Giovanna Massei, D. Cowan, Douglas C. Eckery, Richard E. Mauldin, M. Gomm, P. Rochaix, Fergal Hill, R. Pinkham, Laura A. Miller
Effect Of Vaccination With A Novel Gnrh-Based Immunocontraceptive On Immune Responses And Fertility In Rats, Giovanna Massei, D. Cowan, Douglas C. Eckery, Richard E. Mauldin, M. Gomm, P. Rochaix, Fergal Hill, R. Pinkham, Laura A. Miller
USDA Wildlife Services: Staff Publications
1. As human-wildlife conflicts increase worldwide, novel methods are required for mitigating these conflicts. Fertility control, based on immunocontraceptives, has emerged as an alternative option to lethal methods for managing wildlife.
2. Immunocontraceptives are vaccines that generate an immune response to key components of an animal's reproductive system. Some of these vaccines target the gonadotropin-releasing hormone (GnRH) and have been used successfully as contraceptives for many wildlife species. However, the need to capture animals for treatment limits the field applications of injectable vaccines. The availability of orally delivered immunocontraceptives would increase the breadth of applications of fertility control for wildlife …
Black Bear Use Of Forest Roads In Western Washington, Gary W. Witmer
Black Bear Use Of Forest Roads In Western Washington, Gary W. Witmer
USDA Wildlife Services: Staff Publications
Radiolocations (108) of 20 black bears were used to assess use or avoidance of 3 forest road types in western Washington. Distances of bears to each type of road were compared to distances of 108 random points using t-tests. Females and males avoided 2-lane roads, while only males avoided 1-lane roads, the most common road type in the area. Females, but not males, were located closer to overgrown, spur roads than expected. This road type has substantial cover of grasses, forbs, and berry-producing shrubs along with protective tree cover. This situation may provide easy travel for females along with security …
Implementation Of An Occupancy-Based Monitoring Protocol For A Widespread And Cryptic Species, The New England Cottontail (Sylvilagus Transitionalis), Colin P. Shea, Mitchell J. Eaton, Darryl I. Mackenzie
Implementation Of An Occupancy-Based Monitoring Protocol For A Widespread And Cryptic Species, The New England Cottontail (Sylvilagus Transitionalis), Colin P. Shea, Mitchell J. Eaton, Darryl I. Mackenzie
United States Geological Survey: Staff Publications
Context. Designing effective long-term monitoring strategies is essential for managing wildlife populations. Implementing a cost-effective, practical monitoring program is especially challenging for widespread but locally rare species. Early successional habitat preferred by the New England cottontail (NEC) has become increasingly rare and fragmented, resulting in substantial declines from their peak distribution in the mid-1900s. The introduction of a possible competitor species, the eastern cottontail (EC),may also have played a role. Uncertainty surrounding how these factors have contributed to NEC declines has complicated management and necessitated development of an appropriate monitoring framework to understand possible drivers of distribution and dynamics.

Costs And Effectiveness Of Damage Management Of An Overabundant Species (Sus Scrofa) Using Aerial Gunning, Amy J. Davis, Bruce Leland, Michael Bodenchuk, Kurt C. Vercauteren, Kim M. Pepin
Costs And Effectiveness Of Damage Management Of An Overabundant Species (Sus Scrofa) Using Aerial Gunning, Amy J. Davis, Bruce Leland, Michael Bodenchuk, Kurt C. Vercauteren, Kim M. Pepin
USDA Wildlife Services: Staff Publications
Context. Management of overabundant or invasive species is a constant challenge because resources for management are always limited and relationships between management costs, population density and damage costs are complex and difficult to predict. Metrics of management success are often based on simple measures, such as counts, which may not be indicative of impacts on damage reduction or cost-effectiveness under different management plans.
Aims. The aims of this study were to evaluate the effectiveness of aerial gunning for the management of wild pigs (Sus scrofa), and to evaluate how cost-effectiveness would vary under different relationships between levels of …
Spatial Processes Decouple Management From Objectives In A Heterogeneous Landscape: Predator Control As A Case Study, Peter J. Mahoney, Julie K. Young, Kent R. Hersey, Randy T. Larsen, Brock R. Mcmillan, David C. Stoner
Spatial Processes Decouple Management From Objectives In A Heterogeneous Landscape: Predator Control As A Case Study, Peter J. Mahoney, Julie K. Young, Kent R. Hersey, Randy T. Larsen, Brock R. Mcmillan, David C. Stoner
USDA Wildlife Services: Staff Publications
Predator control is often implemented with the intent of disrupting top-down regulation in sensitive prey populations. However, ambiguity surrounding the efficacy of predator management, as well as the strength of top-down effects of predators in general, is often exacerbated by the spatially implicit analytical approaches used in assessing data with explicit spatial structure. Here, we highlight the importance of considering spatial context in the case of a predator control study in south-central Utah. We assessed the spatial match between aerial removal risk in coyotes (Canis latrans) and mule deer (Odocoileus hemionus) resource selection during parturition using …
Using Species Distribution Models To Define Nesting Habitat Of The Eastern Metapopulation Of Double-Crested Cormorants, Kate L. Sheehan, Samuel T. Esswein, Brian S. Dorr, Greg K. Yarrow, Ron J. Johnson
Using Species Distribution Models To Define Nesting Habitat Of The Eastern Metapopulation Of Double-Crested Cormorants, Kate L. Sheehan, Samuel T. Esswein, Brian S. Dorr, Greg K. Yarrow, Ron J. Johnson
USDA Wildlife Services: Staff Publications
When organisms with similar phenotypes have conflicting management and conservation initiatives, approaches are needed to differentiate among subpopulations or discrete groups. For example, the eastern metapopulation of the double-crested cormorant (Phalacrocorax auritus) has a migratory phenotype that is culled because they are viewed as a threat to commercial and natural resources, whereas resident birds are targeted for conservation. Understanding the distinct breeding habitats of resident versus migratory cormorants would aid in identification and management decisions. Here, we use species distribution models (SDM: Maxent) of cormorant nesting habitat to examine the eastern P. auritus metapopulation and the predicted breeding …

Carnivore Incidents With U.S. Civil Aircraft, Alexander R. Crain, Jerrold L. Belant, Travis L. Devault
USDA Wildlife Services: Staff Publications
Wildlife incidents with aircraft are of concern in the United States as they pose a risk to human safety and economic losses for the aviation industry. Most previous research on wildlife-aircraft incidents has emphasized birds, bats, and ungulates. We queried the Federal Aviation Administration’s National Wildlife Strike Database from 1990 to 2012 to characterize carnivore incidents with U.S. civil aircraft. We found 1016 carnivore incidents with aircraft representing at least 16 species, with coyotes (n = 404) being the species most frequently struck. California and Texas had the most reported incidents and incidents were most likely to occur at …
Human–Carnivore Interactions: Lessons Learned From Communities In The American West, Julie K. Young, Zhao Ma, Ann Laudati, Joel Berger
Human–Carnivore Interactions: Lessons Learned From Communities In The American West, Julie K. Young, Zhao Ma, Ann Laudati, Joel Berger
USDA Wildlife Services: Staff Publications
Types, causes, and intensity of human–carnivore interactions are related to historical context, management policy, and human perception. We used four rural communities in the American West with varying histories and management policies to assess the complexities of human–carnivore interactions and to determine factors influencing individual willingness to coexist with carnivores. By analyzing focus group and interview data from 49 community members, we found that human perceptions towards carnivores and their management were influenced by self-perceived knowledge about carnivores, ability to be heard and have a voice in management decisions, and economic concerns rather than ecological factors. Willingness to coexist with …

United States Geological Survey: Staff Publications
The Yellowstone National Park bison herd is 1 of only 2 populations known to have continually persisted on their current landscape since pre-Columbian times. Over the last century, the census size of this herd has fluctuated from around 100 individuals to over 3000 animals. Previous studies involving radiotelemetry, tooth wear, and parturition timing provide evidence of at least 2 distinct groups of bison within Yellowstone National Park. To better understand the biology of Yellowstone bison, we investigated the potential for limited gene flow across this population using multilocus Bayesian clustering analysis. Two genetically distinct and clearly defined subpopulations were identified …

Managing For Resilience, Craig R. Allen, Graeme S. Cumming, Ahjond S. Garmestani, Phillip D. Taylor, Brian H. Walker
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Early efforts in wildlifemanagement focused on reducing population variability and maximizing yields of selected species. Later, Aldo Leopold proposed the concept of habitat management as superior to population management, and more recently, ecosystem management, whereby ecological processes are conserved or mimicked, has come into favour. Managing for resilience builds upon these roots, and focuses on maintaining key processes and relationships in socialecological systems so that they are robust to a great variety of external or internal perturbations at a range of ecological and social scales. Managing for resilience focuses on system-level characteristics and processes, and the endurance of system properties …

Using Advancements In Cable-Trapping To Overcome Barriers To Furbearer Management In The United States, Stephen Vantassel, Tim L. Hiller, Kelly D. J. Powell, Scott E. Hygnstrom
School of Natural Resources: Faculty Publications
Harvest of furbearers through trapping has been challenged by anti-trapping organizations for centuries, with organizational goals often including prohibition of all forms of trapping. Challenges to trapping may also include dissention among state wildlife agencies, pro-hunting organizations, and pro-trapping organizations. Despite recent efforts by anti-trapping organizations and occasional dissention among consumptive-use groups, national trends in snaring regulations included less restrictive regulations through time. This positive trend may offer opportunities for state wildlife agencies and pro-trapping organizations to enhance the public image of trapping, increase recruitment of trappers, and reverse the increasing trend of wildlife damage and associated costs. We offer …
An Environmental Biography Of Bde Ihanke-Lake Andes: History, Science, And Sovereignty Converge With Tribal, State, And Federal Power On The Yankton Sioux Reservation In South Dakota, 1858-1959, David Nesheim
Department of History: Dissertations, Theses, and Student Research
Lake Andes sits at the center of the Yankton Sioux Reservation in south-central South Dakota and might be described as a prairie pothole, except it encompasses nearly 5,000 acres when full of water, stretching twelve miles long by a mile to a mile and a half wide in a quasi-crescent shape. Originally carved out by a receding glacier during the Wisconsin glaciations, for its entire history the lake has gone dry during low precipitation -- a cycle interrupted after the Bureau of Indian Affairs (BIA) commissioned several artesian wells beginning in 1896. As the lake expanded, the U.S. Fish Commission …

Human–Wildlife Conflicts: Emerging Challenges And Opportunities, Terry A. Messmer
Human–Wildlife Interactions
Wildlife management has been defined as the art and science of applying scientific knowledge and ecological principles to manage wildlife populations for human objectives. Historically, wildlife managers have sought to maintain or increase desirable wildlife species (e.g., game fish, birds, and mammals) to meet human food and recreational needs by directly manipulating their habitats or the populations themselves. However, many contemporary rural and urban environments are inhabited by much larger populations of wildlife than were present a century ago. As local wildlife populations increase, so can the damage caused by them. Additionally, because many rare species inhabit private lands, the …

USGS Northern Prairie Wildlife Research Center
Wetland management in the United States has never been as challenging as in today’s highly modified landscape. Initially, wetland science and management emerged as professions in response to widespread conversion of wetlands to other uses and concerns over negative impacts on wildlife populations, especially migratory birds. Consequently, wetland management was focused on wildlife, and the initial management technique was simply to protect wetlands. However, extensive conversion of lands for agricultural and urban expansion over the past 60 years has modified ecosystem processes at the landscape scale sufficiently to compromise wetland management activities on adjacent lands dedicated to conservation. Moreover, society …

Management Of Urban Coyotes And Attacks In Green Valley, Pima County, Arizona, Christopher D. Carrillo, Jim Schmidt, David Bergman, Gabriel Paz
Wildlife Damage Management Conference Proceedings
Coyote (Canis latrans) attacks on humans, once thought to be rare, have increased in frequency over the past decade. In Arizona, the number of wildlife human encounters has increased as our urban environments have expanded into the coyote’s natural environment. Coyotes have learned to utilize drip irrigation, pet food, household refuse, and pets as prey. The problem of potential coyote attacks is magnified when people intentionally feed coyotes. In some situations, coyotes have begun to act aggressively toward humans, chasing joggers/walkers, confronting people walking their dogs, and stalking small children. People who live in areas where coyotes are …
