Human–Wildlife Interactions
Feeding management can be a good strategy for avoiding wildlife–vehicle collisions (WVCs), which are a worldwide concern. In this study, we aimed to identify grass species that capybaras (Hydrochoerus hydrochaeris) reject as feeding material. These species could be planted to make roadsides less attractive to capybaras and, consequently, decrease WVCs involving this species. We planted 3 grass species (Brachiaria decumbens cv. Basilisk, B. hybrid Mavuno, and Zoysia japonica) in 4 blocks, applying a randomized-complete blocks design. The first 2 species we assumed would be rejected, since some animals do not consume them due to their high …
Asiatic Black Bear Microsite Selection In A Human-Dominated Landscape In The Central Alps, Japan: Implications For Mitigating Human–Bear Conflicts, Tomoki Mori, Shigeyuki Izumiyama
Asiatic Black Bear Microsite Selection In A Human-Dominated Landscape In The Central Alps, Japan: Implications For Mitigating Human–Bear Conflicts, Tomoki Mori, Shigeyuki Izumiyama
Human–Wildlife Interactions
With the rapid expansion of human development and associated changes in landscape use, opportunities for human land sharing with large mammalian carnivores, such as those belong to the family Ursidae is increasing, especially in human-dominated landscapes. Consequently, this increased coexistence has also led to an increase in human–bear (Ursus spp.) interactions. It is important to understand the spatial and temporal reactions (e.g., interactions between cover, time, and humans) of bears to mitigate human–bear conflicts and facilitate coexistence. However, managers often need better information regarding bear microsite habitat selection in areas with higher levels of human–bear encounter risks. We explored …
Tradeoffs May Counteract Effects Of Telecommunication Towers On Osprey Nesting, Gage R. Barnes, Kate G. Slankard, John B. Hewlett, Andrea K. Darracq
Tradeoffs May Counteract Effects Of Telecommunication Towers On Osprey Nesting, Gage R. Barnes, Kate G. Slankard, John B. Hewlett, Andrea K. Darracq
Human–Wildlife Interactions
The number of telecommunication towers (TCTs) throughout the United States has and continues to increase exponentially. Increased TCT placement has been implicated in local population increases in platform nesting birds such as ospreys (Pandion haliaetus). However, osprey use of artificial structures can cause conflicts with humans because of economic costs and risks to human safety. Managers require better information regarding the effect of artificial nesting surfaces, such as TCTS, on osprey reproduction to make informed decisions regarding species conservation and to mitigate potential conflicts. The objective of our study was to evaluate the influence of TCTs on osprey …

Trico: A Novel Repellent For Preventing Deer Damage To Ornamental Shrubs, Paul D. Curtis, Brian C. Eshenaur
Human–Wildlife Interactions
Homeowners whose landscape plants are repeatedly browsed by white-tailed deer (Odocoileus virginianus; deer) desire repellent products that are effective and long-lasting. We conducted a 12-week trial from January 6 through April 5, 2021 to test the duration and efficacy of a novel deer repellent (Trico®) relative to Plantskydd®, a commonly used deer repellent, and untreated plants. We placed treated and control Japanese yew shrubs (Taxus media ‘Hicksii’) at 4 homeowner sites (Birch Hills Drive, Fairview Crescent, Pinegrove Ave., and St. Paul Blvd.) near Rochester, New York, USA, where we detected deer presence. Yews are frequently eaten …

Stakeholder Acceptance Of Wild Equid Fertility Control Mirrors Global Shifts In Attitudes To Wildlife Management, Giovanna Massei, Stephanie L. Boyles Griffin
Human–Wildlife Interactions
Wild equid (horses [Equus ferus] and burros [E. asinus]) populations have increased on public lands in the United States since the passage of the Wild Free-Roaming Horses and Burros Act of 1971. As of March 1, 2022, the Bureau of Land Management (BLM) estimated that wild equid populations on designated herd management areas (HMAs) may exceed 82,000 animals. In 2020, the total population of wild equids in the United States was estimated to exceed 300,000 animals. The BLM sets an appropriate management level (AML) for wild horse and burro herds on each HMA and removes animals …

Line Of Sight: Simulated Aerial Avian Predators Can Reduce Problematic Bird Flyovers Of Airfields, William O'Shea, Neil E. Coughlan, Thomas C. Kelly, Neil Mitham, Jeremy Nicholson
Human–Wildlife Interactions
Collisions between birds and aircraft (bird strikes) are a serious threat to air safety and represent a substantial economic cost to the global aviation industry. In recent years, the frequency of wood pigeons (Columba palumbus) flying over active runways has increased at airports in Ireland. Here, we examine the effectiveness of imitation hawk-kites as a means of excluding wood pigeons from sensitive airfield locations. Over 2 years, during August and September, we conducted control (no kites deployed) and treatment trials (kites deployed) at Casement Aerodrome, an active airfield of approximately 320 ha in County Dublin, Ireland and on …
One Step Closer To A Better Starling Trap, James R. Thiele
One Step Closer To A Better Starling Trap, James R. Thiele
United States Department of Agriculture Wildlife Services: Staff Publications
European starlings (Sturnus vulgaris) are an invasive species in the United States that damage agriculture, personal property, and threaten human health and safety. The U.S. Department of Agriculture Wildlife Services provides technical support to mitigate damage by controlling starling populations at concentrated animal feeding operations, landfills, utilities, and urban areas. Wildlife Services uses DRC-1339, a registered toxicant, to reduce starling populations. Trapping can also be an effective tool but requires more time at a higher cost than DRC-1339. Trapping starlings, however, may be needed to provide a viable alternative to mitigate damage in areas where toxicant use may …

Remote Sensing Applications For Abating Aircraft–Bird Strike Risks In Southeast Brazil, Natalia S. Novoselova, Alexey A. Novoselov, Arthur Macarrão, Guilherme Gallo-Ortiz, Wesley Rodrigues Silva
Human–Wildlife Interactions
The rising number of aircraft collisions with birds requires the development of appropriate mitigation measures to control their populations in the vicinity of airports. The black vulture (Coragyps atratus; vultures) is considered one of the most dangerous species for aviation in Brazil. To better understand the spatial distribution patterns of flying vultures and the risks they may pose to aviation, we studied natural and anthropogenic superficial factors and then numerically estimated and mapped the risk of collision with birds over the Airport Safety Area (ASA) for the Amarais Airport and Presidente Prudente Airport in the southeast part of …

Tracking Canada Geese Near Airports: Using Spatial Data To Better Inform Management, Ryan Askren, Brett E. Dorak, Heath M. Hagy, Michael W. Eichholz, Brian E. Washburn, Michael P. Ward
United States Department of Agriculture Wildlife Services: Staff Publications
The adaptation of birds to urban environments has created direct hazards to air transportation with the potential for catastrophic incidents. Bird–aircraft collisions involving Canada geese (Branta canadensis; goose) pose greater risks to aircraft than many bird species due to their size and flocking behavior. However, information on factors driving movements of geese near airports and within aircraft arrival/departure areas for application to management are limited. To address this need, we deployed 31 neck collar-mounted global positioning system transmitters on Canada geese near Midway International Airport in Chicago, Illinois, USA during November 2015 to February 2016. We used the movement data …

Managing Urban Crow Populations In Japan, Tsuyoshi Yoda
Managing Urban Crow Populations In Japan, Tsuyoshi Yoda
Human–Wildlife Interactions
Crow (Corvus spp.) populations are increasing globally. This is cause for concern because overabundant crow populations can damage agricultural crops, harm native wildlife, and become a nuisance in urban areas. In Japan, the carrion (C. corone) and large-billed crow (C. macrorhynchos) can cause damage to crops and livestock. This damage is predicted to increase in Japan with climate change, especially when precipitation increases, inducing landscape changes that may favor crow populations and activities. In Japan, the primary control method used to manage crow damage is the destruction of nests by a crow control officer who …

Train–Elephant Collisions In A Biodiversity-Rich Landscape: A Case Study From Rajaji National Park, North India, Ritesh Joshi, Kanchan Puri
Human–Wildlife Interactions
Linear developments like railways and highways have a negative impact on ecological processes of wildlife species at a landscape level. The impacts in terms of wildlife mortality and threat to surviving populations of species have been well-studied; however, less work has been done to understand the potential causes of train–wildlife collisions, particularly large mega-fauna such as Asian elephants (Elephas maximus; elephant). In this case study, we review train–elephant collisions (TECs) that occurred in Rajaji National Park (RNP) and discuss some potential causes of TECs along with mitigation measures. The RNP, located in the upper Gangetic plains of northern …

Wildlife Damage To Crops Adjacent To A Protected Area In Southeastern Mexico: Farmers’ Perceptions Versus Actual Impact, Gabriel Can-Hernández, Claudia Villanueva-García, Elías José Gordillo-Chávez, Coral Jazvel Pacheco-Figueroa, Elizabeth Pérez-Netzahual, Rodrigo García-Morales
Human–Wildlife Interactions
Human–wildlife conflicts occur when wildlife has an adverse effect on human activities (e.g., predation of livestock, crop raiding). These conflicts are increasing, particularly in areas surrounding natural protected areas, where villagers engage in subsistence agriculture. Crop damage may cause farmers to retaliate and harm wildlife species considered responsible for the damage. Among the factors that determine the intensity of the conflict are the frequency of the damage and the amount of biomass consumed relative to the perceptions, values, and cultural history of the farmers affected. To better understand the conflicts between farmers and wildlife, we compared farmer perceptions of wildlife …

Sloth Bear Attacks On Humans In Central India: Implications For Species Conservation, Nisha Singh, Swapnil Sonone, Nishith Dharaiya
Human–Wildlife Interactions
Conflicts with wild animals are increasing as human populations grow and related anthropogenic activities encroach into wildlife habitats. A good example of this situation is the increase in conflicts between humans and sloth bears (Melursus ursinus) in India. Sloth bears are known for their aggressive and unpredictable behavior. More human fatalities and injuries have been attributed to sloth bear attacks than all recorded incidences of wildlife attacks in Buldhana Forest Division of Maharashtra, India. We interviewed 51 victims that were attacked by sloth bears between 2009-2017 to better understand the reasons for the attacks. Thirty-four of the attacks …

Avian Fatalities At Wind Energy Facilities In North America: A Comparison Of Recent Approaches, Douglas H. Johnson, Scott R. Loss, K. Shawn Smallwood, Wallace P. Erickson
Human–Wildlife Interactions
Three recent publications have estimated the number of birds killed each year by wind energy facilities at 2012 build-out levels in the United States. The 3 publications differ in scope, methodology, and resulting estimates. We compare and contrast characteristics of the approaches used in the publications. In addition, we describe decisions made in obtaining the estimates that were produced. Despite variation in the 3 approaches, resulting estimates were reasonably similar; about a quarter- to a half-million birds are killed per year by colliding with wind turbines.
Impact Of Wind Energy On Bats: A Summary Of Our Current Knowledge, Cris D. Hein, Michael R. Schirmacher
Impact Of Wind Energy On Bats: A Summary Of Our Current Knowledge, Cris D. Hein, Michael R. Schirmacher
Human–Wildlife Interactions
Since 2003, when it was discovered that large numbers of bats were being killed at wind turbines in the eastern United States, our understanding of the impact of wind energy development on bats has increased and consistent patterns of fatality, including seasonality and species composition have become evident. Yet, many questions remain despite the wealth of data collected across numerous post-construction monitoring studies. We synthesized the recent literature to provide an overview of our current understanding of patterns of bat fatalities at wind energy facilities in the United States and Canada. Our understanding of the impact of wind energy development …

Wind Energy Development: Methods For Assessing Risks To Birds And Bats Pre-Construction, Todd Katzner, Victoria Bennett, Tricia Miller, Adam Duerr, Melissa Braham, Amanda Hale
Human–Wildlife Interactions
Wind power generation is rapidly expanding. Although wind power is a low-carbon source of energy, it can impact negatively birds and bats, either directly through fatality or indirectly by displacement or habitat loss. Pre-construction risk assessment at wind facilities within the United States is usually required only on public lands. When conducted, it generally involves a 3-tier process, with each step leading to more detailed and rigorous surveys. Preliminary site assessment (U.S. Fish and Wildlife Service, Tier 1) is usually conducted remotely and involves evaluation of existing databases and published materials. If potentially at-risk wildlife are present and the developer …

Harvest Demographics Of Temperate-Breeding Canada Geese In South Dakota, 1967–1995, Jeffrey S. Gleason, Jonathan A. Jenks, David E. Naugle, Paul W. Mammenga, Spencer J. Vaa, Jennifer M. Pritchett
Natural Resource Management Faculty Publications
In South Dakota, breeding giant Canada geese (Branta canadensis maxima) have increased substantially, and harvest management strategies have been implemented to maximize hunting opportunity (e.g., special early-September seasons) on local, as well as molt-migrant giant Canada geese (B. c. interior) while still protecting lesser abundant Arcticbreeding Canada geese and cackling geese (e.g., B. hutchinsii, B. minima). Information on important parameters, such as survival and recovery rates, are generally lacking for giant Canada geese in the northern Great Plains. Patterns in Canada goose band recoveries can provide insight into the distribution, chronology, and harvest pressures to which a given goose population …
Methodology For Estimating Deer Browsing Impact, Timothy G. Pierson, David S. Decalesta
Methodology For Estimating Deer Browsing Impact, Timothy G. Pierson, David S. Decalesta
Human–Wildlife Interactions
Because there were no reliable indicators of deer browsing on tree seedling regeneration, we developed methodology that can be used to measure deer browsing impact. We compared 11 years (2002 to 2012) of annual estimates of deer density with coarse (percent-plots-no-regeneration, percent-plots-no-impact) and fine (3 levels of impact on 6 indicator seedling species) indicators within a 29,642-ha study area in northwestern Pennsylvania. Coarse and fine measures met established criteria for indicators of environmental stress (e.g., high deer density); they were predictive of stresses that can be: avoided by management; integrative with causes of stress; responsive to disturbances and changes over …

The National Wildlife Control Training Program: An Evolution In Wildlife Damage Management Education For Industry Professionals, Paul D. Curtis, Raj Smith, Scott Hygnstrom
Human–Wildlife Interactions
Managing wildlife and reducing damage in rural areas has traditionally been achieved by hunting and trapping problem species or by preventing animals from accessing crops and entering buildings. With urban sprawl, specialized tools and management approaches often are needed to reduce wildlife conflicts in developed landscapes. To address these issues, the private wildlife control industry has grown considerably during the past 2 decades. State wildlife agencies have regulatory authority and oversight of this industry, and there is an increasing trend toward licensing or certification of commercial wildlife control operators (WCOs). Regulations differ in every state, however, and no consistent standard …

Administering GonaconTm To White-Tailed Deer Via Hand-Injection Versus Syringe-Dart, Charles S. Evans, Anthony J. Denicola, John D. Eisemann, Robert J. Warren
Human–Wildlife Interactions
Immunocontraceptive vaccines have shown some promise for fertility control of white-tailed deer (Odocoileus virginianus) in urban and suburban habitats where traditional methods of population control may not be applicable. Currently, the only contraceptive vaccine approved by the U.S. Environmental Protection Agency for use in white-tailed deer is GonaConTM Immunocontraceptive Vaccine, but it is registered for use via hand-injection only. It has been suggested that remote-delivery of immunocontraceptives would be more cost-effective than hand-injection, but there is the potential for incomplete injection from a syringe-dart. Therefore, the purpose of our research was to: (1) conduct a dart configuration …

Quantitative Assessment Of Bullet Fragments In Viscera Of Sheep Carcasses As Surrogates For White-Tailed Deer, Luis Cruz-Martinez, Marrett D. Grund, Patrick T. Redig
Human–Wildlife Interactions
Avian scavengers, such as bald eagles (Haliaeetus leucocephalus), can be exposed to lead through the consumption of spent lead from ammunition in carcasses of animals shot with lead-based projectiles. Few studies have examined the degree of bullet fragmentation in viscera (offal) of game mammals. Our objective was to quantify the number of bullet fragments deposited in sheep carcasses shot with different types of lead and lead-free, high-velocity centerfire rifle bullets and with lead projectiles fired from shotguns and muzzleloader rifles marketed for hunting white-tailed deer (Odocoileus virginianus). We hypothesized that after controlling for velocity, angle of …

Modeling The Economic Impacts Of Double-Crested Cormorant Damage To A Recreational Fishery, Stephanie A. Shwiff, Katy N. Kirkpatrick, Travis L. Devault, Steven S. Shwiff
Human–Wildlife Interactions
The double-crested cormorant (Phalacrocorax auritus) has undergone a significant range expansion in the Great Lakes area of the United States since the 1970s, negatively impacting native fish populations and sport fisheries. Effective management of wildlife requires policies and practices that quantify their economic impacts, which is often complicated by multiplier effects in the regional economy. This analysis estimates the potential direct and regional economic impacts of the cormorant to a recreational fishery. We estimated that the potential economic loss was on average $5 million to $66 million annually, as well as 66 to 929 job-years in the region …

Grass Management Regimes Affect Grasshopper Availability And Subsequently American Crow Activity At Airports, Laura A. Kennedy, Ken A. Otter
Human–Wildlife Interactions
With large expanses of open vegetation, airports serve as major attractants for numerous bird species, such as the American crow (Corvus brachyrhynchos), which can lead to high risk of bird–aircraft collision. Previous observations of large influxes of crows at the Prince George Airport (British Columbia, Canada) in July and August suggested that crows were opportunistically foraging on grasshopper (Melanoplus sp.) population eruptions in mown grass during those months. We tested whether grasshoppers were more visible (i.e., easier for crows to detect) under different grass lengths, and whether crows were preferentially attracted to these same grass lengths. Employing …
Parallel Universes? Increasing Connections Between Ipm And Wdm, Lynn Braband
Parallel Universes? Increasing Connections Between Ipm And Wdm, Lynn Braband
Human–Wildlife Interactions
Managing damage by wild vertebrates often is important, and wildlife damage management (WDM) has incorporated important tenets of integrated pest management (IPM). However, largely separate academic backgrounds have nurtured the IPM and WDM communities. The controversial “hot button” topics have tended to differ. While WDM research and outreach have received some IPM funding, and wildlife studies occasionally appear in IPM journals, attendance at infrequent wildlife sessions during IPM meetings has been sparse. The objectives of this paper are to review important examples of collaboration, and evaluate possibilities for future synergy between these related disciplines.

Assessing Gull Abundance And Food Availability In Urban Parking Lots, Dan Clark, Jillian J. Whitney, Kenneth G. Mackenzie, Kiana K. G. Koenen, Stephen Destefano
Human–Wildlife Interactions
Feeding birds is a common activity throughout the world; yet, little is known about the extent of feeding gulls in urban areas. We monitored 8 parking lots in central Massachusetts, USA, during the fall and winter of 2011 to 2013 in 4 monitoring sessions to document the number of gulls present, the frequency of human–gull feeding interactions, and the effectiveness of signage and direct interaction in reducing human-provisioned food. Parking lots were divided between “education” and “no-education” lots. In education lots, we erected signs about problems caused when people feed birds and also asked people to stop feeding birds. We …
Evaluating Competing Preferences Of Hunters And Landowners For Management Of Deer Populations, Gino J. D'Angelo, Marrett D. Grund
Evaluating Competing Preferences Of Hunters And Landowners For Management Of Deer Populations, Gino J. D'Angelo, Marrett D. Grund
Human–Wildlife Interactions
Most state wildlife agencies consider public input in the management of whitetailed deer (Odocoileus virginianus) populations. In 2013, we surveyed deer hunters (n = 3,600) and landowners (n = 4,604) in southwest Minnesota to gauge their preferences for managing deer. We hypothesized a priori that, irrespective of their perceived impacts of deer, hunters would prefer deer populations to be increased and landowners would prefer deer populations to be decreased. Our findings suggest that defining stakeholder groups according to primary associations with deer (i.e., farming and hunting) accurately categorized differences in tolerance levels for deer populations in …

United States Department of Agriculture Wildlife Services: Staff Publications
Wildlife incidents with U.S. civil aircraft cost an estimated $1.4 billion from 1990 to 2010, with mammals 5 times more likely to cause damage than other wildlife. We surveyed 2 general aviation (GA) airports and 6 Part-139 certificated (i.e., certified) airports to assess efficacy of management practices for mammalian species hazardous to aircraft. We obtained information on mammalian species present on airport grounds, types and estimated effectiveness of management techniques, and effort spent on wildlife management. We evaluated management techniques relative to aircraft–wildlife collisions (i.e., incident) frequencies taken from Federal Aviation Administration’s (FAA) National Wildlife Strike Database and species hazard …

Human–Wildlife Interactions
Herbivory by eastern cottontails (Sylvilagus floridanus) can be the source of significant agricultural, nursery, and managed landscape damage. Where cottontails cannot be managed by lethal means or where trap and release is infeasible, repellents may be a reasonable alternative. We tested 8 different repellent formulations (Bobbex Deer Repellent® Canadian formulation concentrate, Bobbex Deer Repellent® Canadian ready-to-use (RTU), Bobbex-R Animal Repellent® concentrate, Bonide Repels All® concentrate, Bonide Deer & Rabbit Repellent® concentrate, Liquid Fence® Deer & Rabbit Repellent concentrate, Plantskydd® soluble powder, and Rabbit Stopper® RTU) on Johnny jump-ups (Viola tricolor), lettuce (Lactuca sativa), and …
