Grass Rejection By Capybaras Can Be Used As A Possible Strategy To Mitigate Road Accidents, André Luiz Gama Nogueira, Sérgio Luiz Gama Nogueira-Filho, Selene Siqueira Da Cunha Nogueira, Denis Sato, Natasha Camilo Maximiano Da Silva, Lilian Elgalise Techio Pereira, Michael Mendl, Adroaldo José Zanella

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 …


Snake Translocation Policies And Practices Within The United States, Robin E. Bedard, Megan Rottenborn, Emily Taylor Jan 2024

Snake Translocation Policies And Practices Within The United States, Robin E. Bedard, Megan Rottenborn, Emily Taylor

Human–Wildlife Interactions

Human–wildlife conflict with nuisance snakes (Serpentes) is rapidly increasing with human population growth and development rates. Translocation of nuisance snakes has become a widespread practice, aided by social media pages connecting people to volunteer and for-profit snake translocators. However, translocators often struggle to find information and resources from wildlife agencies about the policies required, and some may unintentionally use translocation procedures that disregard the health and survival of the snakes. The goals of this study were to (1) obtain data on policies, permitting, and training required for translocating nuisance snakes in each U.S. state that has snakes and (2) compare …

Multi-Year Effectiveness Of Pzp-22 In Free-Roaming Suburban White-Tailed Deer, Allen T. Rutberg, Kali M. Pereira, Kayla A. Grams, John W. Turner Jr.

Human–Wildlife Interactions

To address the challenge that is posed to the use of fertility control to mitigate human–deer (Cervidae) conflicts by the need to regularly re-inoculate free-roaming animals, we captured, ear-tagged, and hand-injected 68 individual adult female white-tailed deer (Odocoileus virginianus) with the PZP-22 immunocontraceptive vaccine from February through April, 2014 to 2017, in the Village of Hastings-on-Hudson, New York, USA. Approximately 2.5 years after initial treatments, we booster-darted 29 of the previously treated females with either PZP-22 or native PZP (ZonaStat-D). We observed fawn production between 2014 and 2021. The combination of initial PZP-22 hand-treatments followed by single dart-delivered PZP …

Human–Wildlife Interactions

Interactions between humans and wildlife include a number of consumptive and non-consumptive forms. In some cases, the increased demand for wildlife viewing can precipitate new human–wildlife conflicts. Mountain goats (Oreamnos americanus; goats) are native to a number of North American mountain ranges from southeastern Alaska to southwestern Montana, USA. Goat habitat typically consists of steep terrain and cold weather habitats, which has left them particularly vulnerable to climate change. Their alpine environments also make them vulnerable to disturbance by aircraft and land-based motorized human activity. We reviewed and characterized situations in which goats in close proximity to humans …


Human–Black Bear Interactions And Public Attitudinal Changes In An Urban Ordinance Zone, Mark A. Barrett, Sarah E. Barrett, David J. Telesco, Michael A. Orlando Jan 2023

Human–Black Bear Interactions And Public Attitudinal Changes In An Urban Ordinance Zone, Mark A. Barrett, Sarah E. Barrett, David J. Telesco, Michael A. Orlando

Human–Wildlife Interactions

Human–bear (Ursus spp.) interactions (HBI) commonly occur in residential areas throughout North America. Negative HBI can be alleviated by using bear-resistant garbage cans (BRC) and by securing other bear attractants (e.g., bird feeders). Since the early 2000s, human and Florida black bear (U. americanus floridanus) densities have increased substantially throughout Florida, USA, concurrently producing an increase in HBI. In central Florida, an area with high densities of humans and black bears, we surveyed 2 neighborhoods that occurred in an urban ordinance zone established in 2016 that required residents to secure anthropogenic food sources. Residents were supplied with …

Evaluation Of The Effect Of Culling On Browse Damage By The Japanese Serow In Gifu Prefecture, Japan, Shiori Ikushima, Naotoshi Kuninaga, Takashi Ikeda, Takuya Okamoto, Makoto Asano, Masatsugu Suzuki

Human–Wildlife Interactions

The Japanese serow (Capricornis crispus; serow) is a protected territorial ungulate native to Japan. However, locally overabundant serow populations can damage forest plantations and agriculture through browsing. Despite government permitted annual culling of serows on forest lands of Gifu Prefecture, Japan, browse damage continues to be reported in hinoki cypress (Chamaecyparis obtusa; cypress) plantations. Sika deer (Cervus nippon; deer), which are co-located with serows can also browse cypress, but their impacts have never been evaluated. The objective of our research was to evaluate the involvement of each species in browse damage and to establish …

Symbiotic Relationship Between Local People And Asiatic Black Bears, Jangchuk Gyeltshen

Human–Wildlife Interactions

There are 8 species of bears (Ursidae) in the world; of these, 6 species are known to occur in Asia. However, in Bhutan, there are only 2 species: the Asiatic black bear (Ursus thibetanus) and the sloth bear (Melursus ursinus). The Asiatic black bear is legally protected by the Forest and Nature Conservation Act of Bhutan 1995. The bear is categorized as vulnerable by the International Union for Conservation of Nature and also included under Appendix I of the Convention on International Trade in Endangered Species. Human–bear conflicts are prevalent in Bhutan, especially at the village …


Enhancing Stakeholder Engagement To Achieve The Sustainable Management Of Free-Roaming Equids, Celeste Carlisle, Dan Adams Jan 2022

Enhancing Stakeholder Engagement To Achieve The Sustainable Management Of Free-Roaming Equids, Celeste Carlisle, Dan Adams

Human–Wildlife Interactions

Wild horse (Equus caballus) and burro (E. asinus; WHB) stakeholders in the American West are divergent in their views of free-roaming equids on public lands. Management authority for free-roaming equids on designated public lands was given to the Bureau of Land Management (BLM) and the U.S. Forest Service (USFS) in 1971 by U.S. Congress with the passing of the Wild and Free-Roaming Horses and Burros Act (WFRHBA). In 1976, the Federal Land Policy and Management Act (FLPMA) mandated the BLM to manage public lands for multiple-uses, which included livestock grazing, energy development, recreation, and timber harvest. …


Wild Boar In Flanders, Belgium: (Dis)Agreements Between Key Stakeholders On Wild Boar Management Objectives, Actions, And Legal Provisions, Caroline Geeraerts, Anneleen Rutten, Emma Cartuyvels, Pieter Verschelde, Sander Devisscher, Francis Turkelboom, Paul Quataert, Jim Casaer Aug 2021

Wild Boar In Flanders, Belgium: (Dis)Agreements Between Key Stakeholders On Wild Boar Management Objectives, Actions, And Legal Provisions, Caroline Geeraerts, Anneleen Rutten, Emma Cartuyvels, Pieter Verschelde, Sander Devisscher, Francis Turkelboom, Paul Quataert, Jim Casaer

Human–Wildlife Interactions

Wild boar (Sus scrofa) reappeared in Flanders, Belgium in 2006 after more than half a century of absence. Besides being a native and highly valued game species in Europe, wild boar are also known to be responsible for car collisions, crop damage, disease transmission, and ecological damage at high densities. The management of wild boar therefore seeks to balance these positive and negative impacts. Given the highly fragmented landscape in Flanders and its multifunctional use, coexistence with wild boar is only possible through integrated management involving relevant stakeholder groups. However, to be successful, this requires that the management …


Household Perceptions And Patterns Of Crop Loss By Wild Pigs In North India, Bivash Pandav, Lakshminarayanan Natarajan, Ankit Kumar, Ajay A. Desai, Banteibor Lyngkhoi Aug 2021

Household Perceptions And Patterns Of Crop Loss By Wild Pigs In North India, Bivash Pandav, Lakshminarayanan Natarajan, Ankit Kumar, Ajay A. Desai, Banteibor Lyngkhoi

Human–Wildlife Interactions

Loss to cultivated crops by wild pigs (Sus scrofa) is widespread and can jeopardize low-income farmers. In India, although there is lot of political interest in the problem, efforts to understand the patterns, correlates, and underlying reasons for wild pig conflict continue to be minimal. We quantified loss of wheat (Triticum aestivum) to wild pigs and assessed the spatial patterns of damage in a forest settlement of Van Gujjar (Haridwar, India), which is a dairy-based pastoralist community. We chose a 4-km2 cultivated area comprising 400 farmlands (each measuring 0.8 ha and belonging to a family) and …

Interactions Between Humans, Crocodiles, And Hippos At Lake Kariba, Zimbabwe, Ivan Marowa, Joshua Matanzima, Tamuka Nhiwatiwa

Human–Wildlife Interactions

Human–wildlife conflicts (HWCs) are on the increase due to shrinking space that results in increased competition for land, water, and other natural resources between humans and wildlife. Investigating the occurrence of HWCs is important in that the results can be used to formulate better management policies and strategies. In this paper, we describe the nature of HWCs emerging between humans and the Nile crocodile (Crocodylus niloticus) and between humans and the African hippopotamus (Hippopotamus amphibius; hippo) on Lake Kariba, Zimbabwe. Lake Kariba is the second largest manmade lake by volume in the world. Conflicts involving humans …

Human-Bear Conflict And Community Perceptions Of Risk In The Zanskar Region, Northern India, Kirti Chavan, Sophie M. Watts, Tsewang Namgail

Human–Wildlife Interactions

The Himalayan brown bear (Ursus arctos isabellinus) is an endangered subspecies of brown bear (U. a. spp.) and is found throughout the Himalayan region of south and central Asia. We describe the type of and the current level of human–bear conflict (HBC) with Himalayan brown bears in the Zanskar region of northern India and suggest potential mitigation methods. Between July and September 2018, we interviewed 218 households across the Zanskar region, all of whom had experienced HBC. Participants reported increasing numbers of HBC events in the last 4 years. The most common form of HBC was damage …

Characteristics Of Non-Fatal Attacks By Black Bears: Conterminous United States, 2000–2017, Janel M. Scharhag, Cady Sartini, Shawn M. Crimmins, Scott E. Hygnstrom, Jeffrey B. Stetz

Human–Wildlife Interactions

Attacks on humans by bears (Ursus spp.) have increased in recent decades, as both human and bear populations have increased. To help mitigate the risk of future attacks, it is important to understand the circumstances in past attacks. Information and analyses exist regarding fatal attacks by both American black bears (Ursus americanus) and brown bears (U. arctos) as well as non-fatal attacks by brown bears. No similarly thorough analyses on non-fatal attacks by black bears are available. Our study addressed this information gap by analyzing all (n = 210) agency-confirmed, non-fatal attacks by black …

Repellent Surface Applications For Pest Birds, Shelagh T. Deliberto, James C. Carlson, Hailey E. Mclean, Caroline S. Olson, Scott J. Werner

Human–Wildlife Interactions

Common pest birds in the United States include the non-native European starling (Sturnus vulgaris), house sparrow (Passer domesticus), and the pigeon (Columba livia domestica), as well as native birds including Canada geese (Branta canadensis) and gull species (Laridae). Large concentrations of pest birds can create human health hazards and monetary losses due to consumption of crops, depredation, and fecal contamination and accumulation. Fecal contamination hazards include the potential spread of zoonotic diseases including antimicrobial-resistant zoonoses and human injury due to the accumulation of fecal material on walking surfaces. Additionally, fecal accumulation causes …


Supporting Farmer Adoption Of Sustainable Bird Management Strategies, Catherine A. Lindell Dec 2020

Supporting Farmer Adoption Of Sustainable Bird Management Strategies, Catherine A. Lindell

Human–Wildlife Interactions

Pest birds cause substantial and costly damage to crops. Managing birds is complex because (1) they are highly mobile, (2) they habituate quickly to many deterrents, (3) some species provide benefits to farmers by deterring and consuming pest insects, rodents, and other birds, and (4) birds are highly valued by many people. Thus, farmers have many issues to consider when developing bird management strategies. Here I discuss recent work indicating that farmer adoption of sustainable agricultural practices is more likely when practices are effective, clear guidelines for implementation are available, implementation is relatively easy, and when practices are linked, in …

Caring For The Circle Of Life: Wildlife Rehabilitation And Sanctuary Care, Donna J. Perry, Jacob P. Averka

Human–Wildlife Interactions

In the United States alone, there are >5,000 state-licensed wildlife rehabilitators in addition to a multitude of other wildlife caregivers across rehabilitation and sanctuary settings. Wildlife rehabilitation and sanctuary care provide a unique lens from which to explore human–wildlife interactions. We examined the experiences of wildlife caregivers within a continuum of acute veterinary services, community-based rehabilitation, and sanctuary care to gain insight into wildlife caregiving and its implications for human–wildlife coexistence. Between 2016 and 2018, we completed in-depth interviews with 15 wildlife caretakers in Massachusetts, Maine, and New Hampshire, USA. In addition to the interviews, we observed 197 unique human–animal …


Role Of Farmer Knowledge In Agroecosystem Science: Rice Farming And Amphibians In The Philippines, Catherine R. Propper, Lisa J. Hardy, Brittni D. Howard, Rica Joy B. Flor, Grant R. Singleton Sep 2020

Role Of Farmer Knowledge In Agroecosystem Science: Rice Farming And Amphibians In The Philippines, Catherine R. Propper, Lisa J. Hardy, Brittni D. Howard, Rica Joy B. Flor, Grant R. Singleton

Human–Wildlife Interactions

Rice (Oryza sativa) agriculture provides food and economic security for nearly half of the world’s population. Rice agriculture is intensive in both land and agrochemical use. However, rice fields also provide aquatic resources for wildlife, including amphibians. In turn, some species may provide ecosystem services back to the farmers working in the rice agroecosystem. The foundation for understanding the complexity of agroecosystem–human relationships requires garnering information regarding human perceptions and knowledge of the role of biodiversity in these rice agroecosystems. Understanding farmer knowledge and perceptions of the ecosystem services provided by wildlife in their fields, along with their …


Evaluation Of The Impacts Of Radio-Marking Devices On Feral Horses And Burros In A Captive Setting, Kathryn A. Schoenecker, Sarah R. B. King, Gail H. Collins Jan 2020

Evaluation Of The Impacts Of Radio-Marking Devices On Feral Horses And Burros In A Captive Setting, Kathryn A. Schoenecker, Sarah R. B. King, Gail H. Collins

Human–Wildlife Interactions

Radio-collars and other radio-marking devices have been invaluable tools for wildlife managers for >40 years. These marking devices have improved our understanding of wildlife spatial ecology and demographic parameters and provided new data facilitating model development for species conservation and management. Although these tools have been used on virtually all North American ungulates, their deployment on feral horses (Equus ferus caballus) or burros (E. asinus) has been limited. To determine if radio-collars and radio-tags could be safely deployed on feral equids, we conducted a 1-year observational study in 2015 to investigate fit and wear of radio-collars …


Capsaicin As A Tool For Repelling Southern Flying Squirrels From Red-Cockaded Woodpecker Cavities, Robert T. Meyer, James A. Cox Jan 2019

Capsaicin As A Tool For Repelling Southern Flying Squirrels From Red-Cockaded Woodpecker Cavities, Robert T. Meyer, James A. Cox

Human–Wildlife Interactions

The southern flying squirrel (Glaucomys volans) is an important kleptoparasite of cavities excavated by the imperiled red-cockaded woodpecker (Dryobates borealis). Flying squirrel usurpation of cavities may affect woodpecker productivity, but current efforts to manage flying squirrels are costly and time consuming. We assessed whether capsaicin could deter flying squirrel use of woodpecker cavities on a site in southwest Georgia, USA. Twenty-nine cavity tree clusters received 4 treatments: capsaicin, water, air, and a control (no treatment). Only capsaicin both removed more flying squirrels from the cavity immediately after its application and decreased the probability of a flying …

Carnivore-Livestock Conflicts In Chile: Evidence And Methods For Mitigation, Valeska Rodriguez, Daniela A. Poo-Muñoz, Luis E. Escobar, Francisca Astorga, Gonzalo Medina-Vogel

Human–Wildlife Interactions

Human population growth and habitat loss have exacerbated human–wildlife conflicts worldwide. We explored trends in human–wildlife conflicts (HWCs) in Chile using scientific and official reports to identify areas and species with higher risk of conflicts and tools available for their prevention and mitigation. The puma (Puma concolor) was considered the most frequent predator; however, fox (Lycalopex spp.) and free-ranging or feral dog (Canis lupus familiaris) attacks were also common. Our results suggest that the magnitude of puma conflicts may be overestimated. Domestic sheep (Ovis spp.) and poultry (Galliformes) were the most common species predated. …

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 …

Do You Hear What I Hear? Human Perception Of Coyote Group Size, Kyle Brewster, Scott E. Henke, Alfonso Ortega, John Tomecek, Benjamin Turner

Human–Wildlife Interactions

Recordings of 1 – 4 coyotes (Canis latrans) that were howling and yip-yapping were played to 427 participants who were asked to estimate the number of coyotes they perceived to hear. Participants were separated by gender (M or F), age group ( 35), resident location (urban, suburban, or rural), and occupation type (rancher/farmer or non-rancher/farmer). Differences between participants concerning gender, age group, resident location, and occupation type were not observed; however, treatment differences were observed. Participants were able to discern differences in the number of coyotes howling with the addition of each coyote; however, participants consistently overestimated the …
