Balancing Agriculture And Wildlife: The Impact Of Elk And Deer Grazing On Farming And Ranching Lands, Ethan Gilliam, Anna Gilliam, Jody Gale Apr 2024

Balancing Agriculture And Wildlife: The Impact Of Elk And Deer Grazing On Farming And Ranching Lands, Ethan Gilliam, Anna Gilliam, Jody Gale

Outcomes and Impact Quarterly

This article examines producers' perceptions of elk and deer grazing on their lands through a survey conducted at the American Farm Bureau Federation (AFBF) National Conference. With 140 complete responses, the study underscores the varying impacts of elk/deer grazing. The findings emphasize the need for enhanced collaboration between agricultural stakeholders and wildlife management authorities to address wildlife grazing impacts effectively. These findings also address the critical opinion of producers toward wildlife inside and outside of their private operations, as well as the interactions between producers and wildlife authorities.


High-Risk Wildlife Strike Regions: An In-Depth Visual Representation Of Wildlife Strikes At And Around Part 139 Airports In Florida., Luke P. Ochs, Flavio A. C. Mendonca Ph.D. Apr 2023

High-Risk Wildlife Strike Regions: An In-Depth Visual Representation Of Wildlife Strikes At And Around Part 139 Airports In Florida., Luke P. Ochs, Flavio A. C. Mendonca Ph.D.

Beyond: Undergraduate Research Journal

Wildlife strikes with aircraft have been and continue to be a problem in the aviation industry costing millions of dollars in both damage and delays. This study used the geoprocessing information system ArcGIS to depict wildlife strikes at Florida’s 26 Part 139 Airports from 2012 to 2021. Importing reports from the National Wildlife Strike Database into ArcGIS, this study used symbology and geoprocessing tools to create a color/ size gradient that depicts the risk (number of damaging strikes out of known strikes) at each airport. Using an interactive map with ArcGIS Online viewers can observe then select each airports vector …


Evaluation Of Invasive Avifauna Management Strategies In North America, Christopher L. Castillo Oct 2022

Evaluation Of Invasive Avifauna Management Strategies In North America, Christopher L. Castillo

Graduate Review

Human action has long been the cause of species introductions into new ecosystems (Lodge 1993). Now, these non-native species are a major global problem both ecologically and economically (Bled et al. 2011). Invasive species can alter habitats, decrease biodiversity, damage human settlements, and destroy agriculture (Townsend Peterson and Vieglais 2001; Kumschick and Nentwig 2010). The United States has been particularly affected by invasive introductions, a multitude of which have been avian species. Various management techniques have been implemented in order to control problem bird populations, however often times these methods are used with a ‘trial and error’ strategy. This review …


Healthy Western Lands: A Proposal For Healthy Rangelands, Wildlife, And Free-Roaming Horses And Burros, James S. Sedinger, Rebekah Stetson Jan 2022

Healthy Western Lands: A Proposal For Healthy Rangelands, Wildlife, And Free-Roaming Horses And Burros, James S. Sedinger, Rebekah Stetson

Human–Wildlife Interactions

The Coalition for Healthy Nevada Lands, Wildlife and Free-roaming Horses (CHNL) is dedicated to proper management of free-roaming horses (Equus caballus) and burros (E. asinus) so rangelands are healthy, which benefits wildlife and the horses and burros themselves. The CHNL proposes the rapid reduction of horses and burros on designated public lands to achieve appropriate management levels (AML). After these reductions, the use of fertility control, supplemented with some gathers and adoption of gathered horses, should allow the Bureau of Land Management to economically maintain horse and burro populations at AML. The CHNL believes this approach …

Main Achievements, Challenges, And Recommendations Of Biodiversity Conservation In China, Fuwen Wei, Xiaoge Ping, Yibo Hu, Yonggang Nie, Yan Zeng, Guangping Huang

Bulletin of Chinese Academy of Sciences (Chinese Version)

After nearly 30 years of development, China has basically realized the comprehensive conservation of biodiversity. Biodiversity conservation has been upgraded to a national strategy and incorporated into the top-level design, with laws and regulations gradually being improved and major scientific breakthroughs continuously being achieved. Through the implementation of major biodiversity conservation and ecological restoration projects, establishment of protected area system, and delineation of ecological red line, important ecosystems and endangered species have been effectively protected, and social participation and public awareness have been significantly improved. In addition, by signing a number of biodiversity-related international conventions and agreements and proposing the …


Survey Of Human-Leopard (Panthera Pardus) Conflict In Ayubia National Park, Pakistan, Muhammad Nabeel Awan, Atif Yaqub, Muhammad Kamran Jun 2020

Survey Of Human-Leopard (Panthera Pardus) Conflict In Ayubia National Park, Pakistan, Muhammad Nabeel Awan, Atif Yaqub, Muhammad Kamran

Journal of Bioresource Management

Wildlife populations are at a risk of extinction mainly because of human-wildlife conflict (HWC). The present study was designed to evaluate the ongoing HWC with special reference to Common Leopard (Panthera pardus) in Ayubia National park through field study as well as a literature-based approach. Questionnaire interview surveys were designed for wildlife officials working in the park and the locals who bear the cost for leopard conflict through livestock depredation and crop damage. The study showed that human-leopard conflict in the study area has been increasing. More than 60% of people considered livestock depredation as the major reason …

New Approach To Health And The Environment To Avoid Future Pandemics, Serge Morand Jan 2020

New Approach To Health And The Environment To Avoid Future Pandemics, Serge Morand

Animal Sentience

This commentary expands Wiebers & Feigin’s target article by pinpointing how declining wildlife, expanding livestock and globalisation contribute to the increase in epidemics of zoonotic diseases, the COVID-19 crisis and future health crises. Epidemics and the emergence of zoonoses are manifestations of dysfunctional links with animals, both wild and domestic, requiring a new approach to health and the environment.

From Wilderness To Timberland To Vacationland To Ecosystem: Maine’S Forests, 1820–2020, Lloyd C. Irland Jan 2020

From Wilderness To Timberland To Vacationland To Ecosystem: Maine’S Forests, 1820–2020, Lloyd C. Irland

Maine Policy Review

The 200 years since Maine statehood span a series of changing metaphors used by people to understand the forest and its values: the forest as wilderness, as timberland, as vacationland, and as ecosystem. These metaphors have succeeded each other over time, but broadly speaking, they all persist to one degree or another. These ways of viewing and using the forest can conflict or can come to uneasy truces, but new developments can revive the tensions. Public policy is always well behind the shifting needs as timberland comes to be seen as vacationland and vacationland as ecosystem. Further, conflicts between different …


Biological Pathways Associated With Wild And Domestic Animals, Cayla Steemer, Laura Carson, Jim Hu, Gloria Regisford Jan 2020

Biological Pathways Associated With Wild And Domestic Animals, Cayla Steemer, Laura Carson, Jim Hu, Gloria Regisford

Pursue: Undergraduate Research Journal

Background: Zoonotic diseases are problematic, in that, they impact both wild and domestic animals alike. Thus, there is a need to investigate the genomes of wild and domestic. Gene ontology (GO) is a major bioinformatics initiative, whereby descriptions of gene products across the database are developed and unified to describe all species. This process is performed by biocurators, who gather, annotate, and validate information on the databases, consequently affording easy access to accurate and updated data. In this study, we investigated the biocuration of two biological processes, DNA integration, which is used for DNA coding, and the tricarboxylic acid (TCA) …


The Illegal Wildlife Trade: Through The Eyes Of A One-Year-Old Pangolin (Manis Javanica), Lelia Bridgeland-Stephens Jan 2020

The Illegal Wildlife Trade: Through The Eyes Of A One-Year-Old Pangolin (Manis Javanica), Lelia Bridgeland-Stephens

Animal Studies Journal

This paper explores the literature on the illegal wildlife trade (IWT) by following the journey of a single imagined Sunda pangolin (Manis javanica) through the entire trading process. Literature on IWT frequently refers to non-human animals in terms of collectives, species, or body parts, for example ‘tons of pangolin scales’, rather than as subjective individuals. In contrast, this paper centralizes the experiences of an individual pangolin by using a cross- disciplinary methodology, combining fact with a fictional narrative of subjective pangolin experience, in an empathetic and egomorphic process. The paper draws together known legislation, trade practices, and pangolin biology, structured …


Wildlife Survey Of National Parks To Assess Reptilian Biodiversity, Ajk, Jibran Haider, Inayatullah Malik, Sabiha Shamim Oct 2019

Wildlife Survey Of National Parks To Assess Reptilian Biodiversity, Ajk, Jibran Haider, Inayatullah Malik, Sabiha Shamim

Journal of Bioresource Management

The class Reptilia belongs to phylum Chordata. This group forms a large community of the land vertebrates. However, they remain relatively under-examined. Roll et al. (2017) studied the global distribution of more than 10,000 reptiles. Nearly194 reptilian species have been reported from Pakistan (WWF, n.d.). Five protected parks were studied from February 2008 to May 2010. Dhirkot Nature Reserve (DNR), Banjosa Nature Reserve (BNR), Tolipir National Park (TNP), Pir Chanasi National Park (PCNP) and Pir Lasura National Park (PLNP) were considered. Fifteen species of reptiles were observed in TNP. Ten species of reptiles were recorded from PCNP. Ten species of …

Assessing Individual And Population-Level Effects Of Anticoagulant Rodenticides On Wildlife, Niamh Quinn Jan 2019

Assessing Individual And Population-Level Effects Of Anticoagulant Rodenticides On Wildlife, Niamh Quinn

Human–Wildlife Interactions

Anticoagulant rodenticides have been detected in many species of wildlife worldwide. However, the origins, exposure pathways, and effects of this exposure are not well understood. To accurately characterize the risks to wildlife from rodenticide use, better information is needed regarding the proportion of populations being exposed, what proportion of individuals in populations are affected, and in what ways. The relationship between anticoagulant rodenticide concentrations found in wildlife and the rate of mortality or illness have been the subjects of much research. Residue levels observed in liver and whole-body analyses vary and overlap extensively among apparently healthy asymptomatic individuals and sublethal …


Cognition, Emotion, Personality And The Conservation And Management Of Wild Ungulates, Rob Found Jan 2019

Cognition, Emotion, Personality And The Conservation And Management Of Wild Ungulates, Rob Found

Animal Sentience

Increasing public understanding of the complexity of wild ungulates can improve animal welfare and advance global conservation efforts of these keystone species. Unfortunately, shaping public opinion on wild species is challenging because personal experience with wildlife is declining, popular education is still biased towards the predator instead of the prey, and scientific research is more difficult to conduct on wild ungulates compared to those on farms, in zoos, or otherwise in captivity. Nevertheless, studies of cognition, individuality, and intelligence of wild ungulates are increasing. I briefly highlight some major results from my own work on complexity in wild elk, illustrating …

Multiple-Use Management Of Western U.S. Rangelands: Wild Horses, Wildlife, And Livestock, Rick E. Danvir Jan 2018

Multiple-Use Management Of Western U.S. Rangelands: Wild Horses, Wildlife, And Livestock, Rick E. Danvir

Human–Wildlife Interactions

Since 1959, the U.S. Congress has legislated the treatment and management of wild horses (Equus ferus caballus ) and burros (E. asinus ; WHB). While the legislation has ensured WHB a place as western rangeland icons, subsequent congressional actions, in response to public lobbying, have limited federal managers’ ability to manage WHB populations under the U.S. public land multiple-use doctrine. Federal land managers tasked with managing for multiple and competing interests on public lands of the western United States must not only consider WHB habitat requirements, but also wildlife species diversity and livestock grazing. Developing multiple-use management strategies while fulfi …


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 …

A Review Of Contemporary U.S. Wild Horse And Burro Management Policies Relative To Desired Management Outcomes, Keith A. Norris Jan 2018

A Review Of Contemporary U.S. Wild Horse And Burro Management Policies Relative To Desired Management Outcomes, Keith A. Norris

Human–Wildlife Interactions

Legally defined “wild” horse (Equus ferus caballus ) and burro (E. asinus ; WHB) populations in the United States exceed established population objectives. The context of WHB policy and management can be categorized into ecological, geographical, legal, social, and political perspectives. Ecologically, all WHB populations in the United States are considered feral animals, but certain populations are afforded protection and management by the federal Wild Free-Roaming Horses and Burros Act (WFRHBA) of 1971. The current policy and management paradigms under which the WFRHBA is being implemented has contributed to rangeland degradation, poor WHB health, and impacts to native wildlife. This …


Use Of Soil Chemical Analysis To Detect Commercial Wildlife Game Baits, Aaron Haines, Angela Fetterolf, Meta Griffin, Tristan Conrad, Steven Kennedy Sep 2017

Use Of Soil Chemical Analysis To Detect Commercial Wildlife Game Baits, Aaron Haines, Angela Fetterolf, Meta Griffin, Tristan Conrad, Steven Kennedy

Human–Wildlife Interactions

Hunters and poachers often use commercially-available, nutrient-rich baits to attract wildlife game animals. We used atomic absorption spectroscopy and ion selective electrochemical analysis techniques to determine whether two common proprietary baits (Deer Cane and Acorn Rage) would leave detectable chemical signatures in soil (i.e., Na+, Cl-, and Ca+2). Our goal was to evaluate low cost tests which could be replicated by wildlife conservation officers in the field. To complete the evaluation we randomly placed two commercial baits on 3 sites in The Millersville University Biological Preserve in Millersville, PA. We collected soils samples from …

A Check List Of The Avifauna Of Loi-Bher Wildlife Park Islamabad, Madeeha Manzoor, Sabiha Shamim, Fida Muhammad Khan

Journal of Bioresource Management

Despite its relatively small area, Loi-Bher wild life park is quite diverse with respect to the avifauna. The common bird species found in the area are: bulbuls, pies, pigeons, parakeets, mynas, babblers, warblers, rollers, bee-eaters, doves, crows and pheasants. Over 40 species of Broad-leaved trees, shrubs and woody climbers have been identified in this zone e.g. Acacia modesta, Morus alba, Bauhinia variegata, Punica granatum, Aristida cynnantha, Acacia nilotica, Dalbergia sisso, etc. Human settlements in designated natural areas of the Loi-Bher wild life park constitute the most serious threat to the park resources.

A Benefit-Cost Analysis Decision Framework For Mitigation Of Disease Transmission At The Wildlife–Livestock Interface, Stephanie A. Shwiff, Steven J. Sweeney, Julie L. Elser, Ryan S. Miller, Matthew L. Farnsworth, Pauline Nol, Steven S. Shwiff, Aaron M. Anderson

Human–Wildlife Interactions

The economics of managing disease transmission at the wildlife–livestock interface have received heightened attention as agricultural and natural resource agencies struggle to tackle growing risks to animal health. In the fiscal landscape of increased scrutiny and shrinking budgets, resource managers seek to maximize the benefits and minimize the costs of disease mitigation efforts. To address this issue, a benefit-cost analysis decision framework was developed to help users make informed choices about whether and how to target disease management efforts in wildlife and livestock populations. Within the context of this framework, we examined the conclusions of a bene� t-cost analysis conducted …


A Conceptual Model To Determine Vulnerability Of Wildlife Populations To Offshore Wind Energy Development, M. Wing Goodale, Iain J. Stenhouse Jan 2016

A Conceptual Model To Determine Vulnerability Of Wildlife Populations To Offshore Wind Energy Development, M. Wing Goodale, Iain J. Stenhouse

Human–Wildlife Interactions

As offshore wind energy development is planned in the United States, there is an increasing need for pre- and post-construction monitoring plans to be focused on species determined to be most vulnerable to hazards of a specific project. We propose a conceptual model that incorporates biological and sociological parameters. Specifically, we suggest that demographic, ethological/biological, and population sensitivity be considered with legal protection, economic importance, and/or stakeholder interest. We recommend that vulnerability determinations include qualitative and quantitative methods.

Tree Cavities And Associated Vertebrate Fauna In A Coniferous Forest Of Dhirkot, Azad Jammu And Kashmir Part Of Pakistan, Iftikhar Hussain, Sajid Abbasi, Sarwat Naz Mirza, Maqsood Anwar, Muhammad Rais, Tariq Mahmood

Turkish Journal of Zoology

Tree cavities are a globally important structural element of forest ecosystems that host numerous cavity-dwelling vertebrates, but they have received little research in Pakistan. We investigated cavity-bearing trees, the attributes of their cavities, and their associated vertebrate fauna in a coniferous forest of Pakistan. We recorded 1140 trees in a 2-km^2 sampled area. We found 211 cavities (64% decay-formed and 36% excavated cavities) in 83 trees (41% live and 59% snags). Of the cavities found, 74% were recorded in trunks and 26% were in branches. Only 28% of the cavities showed signs of recent use by any vertebrate species. We …

A Decade Of U.S. Air Force Bat Strikes, Suzanne C. Peurach, Carla J. Dove, Laura Stepko

Human–Wildlife Interactions

From 1997 through 2007, 821 bat strikes were reported to the U.S. Air Force (USAF) Safety Center by aircraft personnel or ground crew and sent to the National Museum of Natural History, Smithsonian Institution, for identification. Many samples were identified by macroscopic and or microscopic comparisons with bat specimens housed in the museum and augmented during the last 2 years by DNA analysis. Bat remains from USAF strikes during this period were received at the museum from 40 states in the United States and from 20 countries. We confirmed that 46% of the strikes were caused by bats, but we …

Safety Management Systems: How Useful Will The Faa National Wildlife Strike Database Be?, Richard A. Dolbeer, Sandra E. Wright

Human–Wildlife Interactions

The National Wildlife Strike Database for Civil Aviation in the United States became operational in 1995 with the initiation of data entry of all strike reports beginning in 1990. The database contained 82,057 reported strikes from 1990 to 2007. About 9,800 of these strike reports noted damage to the aircraft, of which 2,700 indicated the damage was substantial. The database has proven to be a useful source of objective information on the extent and nature of wildlife strikes for personnel at individual airports and for researchers and regulatory agencies at the national level. With the impending requirement for airports in …
