A social network analysis of actors involved in wild pig (\u3ci\u3eSus scrofa\u3c/i\u3e) management in Missouri

Wild pigs (Sus scrofa) cause significant damage to agriculture and native ecosystems and can transmit diseases to animals and people. Management responses designed to reduce population numbers are needed to mitigate these threats. Identifying networks of key actors, including the ways in which they interact, is valuable for purposes of better understanding opportunities or constraints that generate or impede effective management responses. The goal of our study was to understand the network of organizations, and the personnel working within them, that were active in wild pig management, research, or policy initiatives in Missouri during 2018–2020 by 1) identifying individuals and organizations involved in the network, 2) investigating the attributes of relevant personnel, 3) determining the structural patterns of the network, and 4) examining how the network structure could be optimized to improve communication and collaboration efforts. Results from a social network analysis identified 150 personnel affiliated with 26 organizations actively working on wild pig issues in Missouri. The network was largely homogenous based on respondents\u27 attributes, had low density, and was relatively fragmented, small, decentralized with few ties per node, and separated with few brokers. We emphasize the importance of understanding the strengths and weaknesses of a network\u27s structure in facilitating effective collective action to manage wild pigs

Machine Learning as a Tool for Wildlife Management and Research: The Case of Wild Pig-Related Content on Twitter

Wild pigs (Sus scrofa) are a non-native, invasive species that cause considerable damage and transmit a variety of diseases to livestock, people, and wildlife. We explored Twitter, the most popular social media micro-blogging platform, to demonstrate how social media data can be leveraged to investigate social identity and sentiment toward wild pigs. In doing so, we employed a sophisticated machine learning approach to investigate: (1) the overall sentiment associated with the dataset, (2) online identities via user profile descriptions, and (3) the extent to which sentiment varied by online identity. Results indicated that the largest groups of online identity represented in our dataset were females and people whose occupation was in journalism and media communication. While the majority of our data indicated a negative sentiment toward wild pigs and other related search terms, users who identified with agriculture-related occupations had more favorable sentiment. Overall, this article is an important starting point for further investigation of the use of social media data and social identity in the context of wild pigs and other invasive species

Texas Hunters’ Perceptions Regarding the Acceptability of Toxicants to Control Wild Pig Populations

Wild pigs (Sus scrofa) are an invasive species in the United States. They damage agriculture, degrade water quality and ecological communities, and host a number of viruses, parasites, and bacteria transmissible to humans and animals. In states such as Texas, USA, where wild pigs cause extensive damage to agriculture and property, officials have considered allowing for the use of toxicants to control wild pig populations. To provide decision-makers with information regarding stakeholders’ perceptions of the use of toxicants to control wild pigs, we surveyed Texas hunters in 2019 to assess the level of acceptance of a hypothetical wild pig toxicant, the sociodemographic and other factors most closely associated with acceptability of such a toxicant, and the specific concerns that underlie hunters’ positions on the use of such a toxicant. We received 37,317 completed responses to an online, self-administered survey. Respondents were divided over the use of a toxicant, with 43% finding a toxicant acceptable, 18% neutral, and 39% finding a toxicant unacceptable. The factor most closely associated with acceptance of a wild pig toxicant was respondents’ desired wild pig population size in Texas (χ2 = 3,657.7, P \u3c 0.001, V = 0.26), with 70% of respondents who preferred that wild pigs be completely removed from Texas finding the use of a toxicant to be acceptable, compared to 14% of respondents who preferred that wild pig populations increase or stay the same. The most commonly raised concerns in connection with toxicant usage were potential negative impacts to nontarget animals (33%) and negative impacts to human health (24%). Our research suggests that while achieving a consensus among Texas hunters on toxicant usage is unrealistic, building majority support may be possible if the identified concerns are sufficiently addressed in product development and outreach

Social identity and acceptability of wild pig (Sus scrofa) control actions: A case study of Texas hunters

Wild pigs (Sus scrofa) pose significant challenges to wildlife managers. This research explored Texas hunters’ acceptability of wild pig control actions, and whether acceptability varied according to hunters’ affiliation with four different categories of natural resource organizations as an indicator of social identity. Results of a survey (n = 37,317) revealed that most hunters were accepting of all control actions except toxicants and non-lethal deterrents. Mean acceptability scores for each action differed significantly across the four affiliation categories, but effect sizes were minimal. Hunters affiliated with agricultural organizations were the most accepting of control actions, while hunters with no organizational affiliations were least accepting. Findings suggested that while the type of organization with which a hunter affiliates provides some basis for predicting acceptability of control actions, the association is likely not significant enough to warrant differentiating wild pig outreach messaging on the basis of affiliation

Social media as a window into human-wildlife interactions and zoonotic disease risk: an examination of wild pig hunting videos on YouTube

Wild pigs (Sus scrofa) damage agriculture and the environment, as well as transmit diseases to animals and people. Hunters are particularly vulnerable to zoonotic disease risks when harvesting wild pigs. Management agencies have endeavored to inform the public about disease risks associated with wild pigs and best practices for mitigating such risks. However, the extent that this guidance has reached hunters and influenced their practices is unclear. We approached this topic through an analysis of wild pig hunting videos on YouTube. We found evidence of relatively few behaviors and communications regarding disease risks and best practices for personal safety. In contrast, many videos showed behaviors that could increase the risk of disease transmission to the subjects and other animals. We emphasize the importance of understanding the influence of social media on viewers and discuss implications for management agencies, including opportunities for strategic messaging in public health campaigns

Understanding tolerance for an invasive species: An investigation of hunter acceptance capacity for wild pigs (\u3ci\u3eSus scrofa\u3c/i\u3e) in Texas

Invasive species and their establishment in new areas have significant impacts on the ecological, economic, and social well-being of our planet. Wild pigs (Sus scrofa) are one of the world’s most formidable invasive species, particularly in the United States. They cause significant damage to agriculture and ecosystems, and can transmit diseases to livestock, wildlife, and people. There is an inherent social dimension to the issue of wild pigs due in part to the fact that people hunt them. Hunting contributes to both the control and spread of this species. The objectives of this study were to: 1) determine hunters’ overall tolerance for wild pigs; and 2) identify what factors predict hunters’ tolerance. Results obtained from a survey of Texas hunters in 2019 indicated that 83% of hunters had a low level of tolerance for wild pigs, with approximately 63% preferring to see the population reduced and 20% preferring to see the population completely removed. Fourteen percent preferred that wild pig numbers remain the same, and 2% preferred to see numbers increase. Results from regression analysis indicated that approximately 53% of the variance in tolerance for wild pigs was explained by motivations and preferences for hunting wild pigs, level of concern for wild pig damage, and overall attitudes toward wild pigs. Results of this research are useful in expanding current knowledge about human tolerance for wildlife, including those species that are non-native and invasive, and in identifying important factors affecting how hunters perceive and interact with wild pigs. Study findings are also helpful in informing the development of effective and socially acceptable management plans for wild pigs, as well as communication efforts aimed at influencing hunters’ attitudes and behaviors in the wild pig management context

Texas hunters' attitudes toward wild pigs (Sus scrofa) and their management: an applied approach for wildlife managers

Abstract 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 pigs and were least tolerant in the San Angelo district. Study findings are useful in informing socially acceptable and contextually appropriate wild pig management plans. Our research serves as an approach that matches the units of analysis with the units of management for decision‐making
