Comprehensive Assessment Of Restoration Seedings To Improve Restoration Success, Kari E. Veblen, Thomas Monaco, Jason Vernon, Danny Summers, Kevin Gunnell, Eric Thacker, Joe Robins, Lacey Wilder, Corinna Riginos Jan 2018

Comprehensive Assessment Of Restoration Seedings To Improve Restoration Success, Kari E. Veblen, Thomas Monaco, Jason Vernon, Danny Summers, Kevin Gunnell, Eric Thacker, Joe Robins, Lacey Wilder, Corinna Riginos

Wildland Resources Faculty Publications

Restoration projects rely on seedling establishment and persistence to foster invasion resistance and improve resilience to environmental stress and disturbance (James et al. 2010; Chambers et al. 2014). However, few studies have comprehensively evaluated the landscape-level performance of seeded species or the factors that control their short-term establishment and long-term persistence (Hardegree et al. 2011; Knutson et al. 2014). Assessing the role of these factors across physiographic regions that experience high temporal and spatial variability in environmental conditions will reveal the effectiveness of various pre-seeding land treatments and enhance our capacity to select appropriate restoration species for specific ecological sites …

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 …

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 …

Framing Contemporary U.S. Wild Horse And Burro Management Processes In A Dynamic Ecological, Sociological, And Political Environment, J. Derek Scasta, Jacob D. Hennig, Jeffrey L. Beck Jan 2018

Framing Contemporary U.S. Wild Horse And Burro Management Processes In A Dynamic Ecological, Sociological, And Political Environment, J. Derek Scasta, Jacob D. Hennig, Jeffrey L. Beck

Human–Wildlife Interactions

The Wild Free-Roaming Horses and Burros Act (WFRHBA) of 1971 established all “unbranded or unclaimed” equids on U.S. public lands as “living symbols of the historic and pioneer spirit of the West.” Today, >72,000 feral horses (Equus ferus caballus) and burros (E . asinus ; WHB) live on western U.S. public rangelands. The number of WHBs exceeds the Bureau of Land Management’s maximum Appropriate Management Level (AML) of 26,715 by a factor of approximately 2.7 and has nearly doubled from 2007–2015. The AML was set to balance WHB numbers with rangeland health and support other uses such as wildlife habitat …

Wild Horse Demography: Implications For Sustainable Management Within Economic Constraints, Robert A. Garrott Jan 2018

Wild Horse Demography: Implications For Sustainable Management Within Economic Constraints, Robert A. Garrott

Human–Wildlife Interactions

Management of wild horse (Equus ferus caballus ) populations on western U.S. rangelands has been a challenge since horses were given legal protection through the passage of the Wild Free-Roaming Horses and Burros Act (WFRHBA) in 1971. Horses have no eff ective predators, and unmanaged populations can double in 4–5 years and triple in 6–8 years. In order to meet the multiple-use paradigm for managing public rangelands, the Bureau of Land Management (BLM) has limited horse population growth through the periodic capture and removal of animals. While the WFRHBA mandates disposal of captured horses through placement into private ownership and …

A Review Of Economic Studies Relating To The Bureau Of Land Management's Wild Horse And Burro Program, Paul M. Jakus Jan 2018

A Review Of Economic Studies Relating To The Bureau Of Land Management's Wild Horse And Burro Program, Paul M. Jakus

Human–Wildlife Interactions

This paper reviews literature addressing the benefits and costs of the Bureau of Land Management’s Wild Horse and Burro (WHB) Program. Within the framework of a comprehensive benefit cost analysis of the WHB Program, I find that program cost estimates are readily available from numerous sources. A more limited set of estimates of the opportunity cost of WHB on the range is available, as is a single estimate of the benefits provided by animal adoption. In contrast, there are no economic estimates of ecological damages caused by WHB in excess of the Appropriate Management Level, nor does a search of …

Spatial Ecology Observations From Feral Horses Equipped With Global Positioning System Transmitters, Jacob D. Hennig, Jeffrey L. Beck, J. Derek Scasta Jan 2018

Spatial Ecology Observations From Feral Horses Equipped With Global Positioning System Transmitters, Jacob D. Hennig, Jeffrey L. Beck, J. Derek Scasta

Human–Wildlife Interactions

Our understanding of the spatial ecology of feral horses (Equus ferus caballus ) and burros (E . asinus ) in the United States is limited. Robust location data are needed to better understand the permeability of Bureau of Land Management Herd Management Area boundaries, relative to feral horse movement patterns and home ranges. To increase our understanding of feral horse movement, in February to March 2017, we deployed global positioning system (GPS) collars on 14 females ≥5 years old that were captured in the Adobe Town Herd Management Area (ATHMA) of southcentral Wyoming, USA. Herein, we report initial results from …

Resource Selection Of Free-Ranging Horses Influenced By Fire In Northern Canada, Sonja E. R. Leverkus, Samuel D. Fuhlendorf, Marten Geertsema, Brady W. Allred, Mark Gregory, Alexandre R. Bevington, David M. Engle, J. Derek Scasta Jan 2018

Resource Selection Of Free-Ranging Horses Influenced By Fire In Northern Canada, Sonja E. R. Leverkus, Samuel D. Fuhlendorf, Marten Geertsema, Brady W. Allred, Mark Gregory, Alexandre R. Bevington, David M. Engle, J. Derek Scasta

Human–Wildlife Interactions

Free-ranging or feral horses (Equus ferus caballus) were important to the livelihood of First Nations and indigenous communities in Canada. The early inhabitants of the boreal region of British Columbia (BC) capitalized on naturally occurring wildfires and anthropogenic burning to provide forage for free-ranging horses and manage habitat for wildlife. This form of pyric herbivory, or grazing driven by fi re via the attraction to the palatable vegetation in recently burned areas, is an evolutionary disturbance process that occurs globally. However, its application to manage forage availability for free-ranging horses has not been studied in northern Canada. Across Canada, there …

Feral Horse Management In Parque Provincial Ernesto Tornquist, Argentina, Alberto L. Scorolli Jan 2018

Feral Horse Management In Parque Provincial Ernesto Tornquist, Argentina, Alberto L. Scorolli

Human–Wildlife Interactions

The number of feral horses (Equus ferus caballus) in the world has been estimated at 1.5–2 million, of which 5,000–10,000 occur in Argentina. Feral horses are considered an invasive alien species in Argentina, and as such, create a problem for biodiversity conservation. Only the population in Parque Provincial Ernesto Tornquist, Buenos Aires province, has been managed. In this paper, I discuss the conflicts between feral horse advocates, government authorities, and researchers that occurred after management actions were implemented and identify some factors that contributed to the conflict in positive and negative manners as well as some confusing concepts and ideas. …

A Review Of Contemporary Contraceptives And Sterilization Techniques For Feral Horses, Albert J. Kane Jan 2018

A Review Of Contemporary Contraceptives And Sterilization Techniques For Feral Horses, Albert J. Kane

Human–Wildlife Interactions

This commentary provides a brief review of the history of contraceptive research eff orts for feral horses (Equus ferus caballus) as well as the contraceptives and sterilization techniques currently available for feral horses. Porcine zona pellucida (PZP) immunocontraceptives have received the most attention and use over the past 40 years, but other treatments such as the GnRH vaccine Gonacon™-Equine are also available. Optimization of these treatments as well as the development of other molecular approaches, intrauterine devices, and surgical techniques is ongoing.

Consequences Of Porcine Zona Pellucida Immunocontraception To Feral Horses, Cassandra M.V. Nuñez Jan 2018

Consequences Of Porcine Zona Pellucida Immunocontraception To Feral Horses, Cassandra M.V. Nuñez

Human–Wildlife Interactions

Porcine zona pellucida (PZP) immunocontraception was developed to provide a more humane, effective, and inexpensive method of population regulation for wildlife species. It has been used to regulate populations of several species including white tailed deer (Odocoileus virginianus), elk (Cervus elaphus ), black bear (Ursus americanus ), and the feral horse (Equus ferus caballus) with varying levels of success. Early studies on Assateague Island National Seashore, Maryland, USA, suggested PZP was as an ideal form of fertility control because it reduced the likelihood of conception to

Managing Healthy Wild Horses And Burros On Healthy Rangelands: Tools And The Tool Box, Callie Hendrickson Jan 2018

Managing Healthy Wild Horses And Burros On Healthy Rangelands: Tools And The Tool Box, Callie Hendrickson

Human–Wildlife Interactions

The Wild and Free-Roaming Horse and Burro Act (WFRHBA) of 1971 authorized the Bureau of Land Management (BLM) and the U.S. Forest Service (USFS) to manage feral horses (Equus ferus caballus ) and burros (E. asinus ) on public lands in the United States. This special issue of Human–Wildlife Interactions has explored in-depth the ecological, policy, political, practical, and sociological issues pertinent to the BLM and USFS management of wild horses and burros. In this commentary, I summarize the pros and cons of the available contemporary policy and management options—the tools in the BLM and USFS toolbox— that can contribute …

The Future Of Wildlife Damage Management, William H. Clay Jan 2018

The Future Of Wildlife Damage Management, William H. Clay

Human–Wildlife Interactions

In January 2018, I retired after a 35-year career in the wildlife damage management profession. I would like to off er my perspective on what the profession was like when I began my career, what it’s like currently, and what I think the future holds. Thirty-five years ago in our program, wildlife damage management activities across the country focused primarily on protecting livestock from predators as well as protecting many agricultural crops like corn, rice, and sunflowers from bird damage. Since transferring from the Department of the Interior to the Department of Agriculture in 1986, we have seen a significant …

Physiological Responses In Reindeer To The Application Of A Conducted Electrical Weapon, Camilla L. Lieske, Kimberlee B. Beckmen, Larry L. Lewis Jan 2018

Physiological Responses In Reindeer To The Application Of A Conducted Electrical Weapon, Camilla L. Lieske, Kimberlee B. Beckmen, Larry L. Lewis

Human–Wildlife Interactions

Conducted Electrical Weapons (CEWs) have potential as effective alternatives to chemical restraint for short-term non-routine capture and handling as well as aversion hazing of wildlife. To assess immediate and delayed physiologic effects of exposure to a CEW, we assigned 15 captive reindeer (Rangifer tarandus tarandus) to one of three treatment groups: immobilized with carfentanil and xylazine (CX), 10 second exposure to a CEW, or exposure to the CEW while immobilized with CX (CEW+CX). Blood samples were collected pre-treatment, immediately post-intervention, 10 min, 20 min, 4 hours, and 24 hours post-intervention. Physiologic effects were evaluated by analysis of blood, …

Experimental Tests Of Nonsurgical Reproductive Inhibitors To Prevent Coyote Reproduction, Julie K. Young, Marjorie J. Macgregor, Eric M. Gese, Douglas C. Eckery Jan 2018

Experimental Tests Of Nonsurgical Reproductive Inhibitors To Prevent Coyote Reproduction, Julie K. Young, Marjorie J. Macgregor, Eric M. Gese, Douglas C. Eckery

Human–Wildlife Interactions

Sterilization is an effective nonlethal tool to reduce livestock depredation by coyotes (Canis latrans) because adults without pups to provision are less likely to kill livestock. Surgical sterilization is costly and invasive, so identifying non-surgical methods for canids that allows wide-scale application is important. We conducted a preliminary assessment of two types of reproductive inhibitors (gonadotropin releasing hormone (GnRH) vaccine and deslorelin, a GnRH agonist, on coyote reproductive capabilities. We treated captive coyotes with a GnRH vaccine (n = 6 males, n = 6 females) or deslorelin (n = 6 males), measured number of litters and pups born, …

Strike Hazard Posed By Columbids To Military Aircraft, Melanie R. Colón, Ashley M. Long Jan 2018

Strike Hazard Posed By Columbids To Military Aircraft, Melanie R. Colón, Ashley M. Long

Human–Wildlife Interactions

Wildlife-aircraft strikes threaten both human and animal safety and result in hundreds of millions of dollars per year in aircraft damage and lost flight hours. Large-bodied birds are especially hazardous to aircraft. However, given high-speed flight at low altitudes, military aircraft may be especially vulnerable to strikes and more susceptible to damage even when encountering small birds. We summarized all wildlife-aircraft strike records from Randolph Air Force Base (San Antonio, Texas) over a 25-year period and compared the number and cost of strikes across avian species and species groups. Because columbids (i.e., pigeons and doves) are among the most frequently …

Toward Sustainable Conservation And Management Of Human-Wildlife Interactions In The Mmadinare Region Of Botswana: Villagers’ Perceptions On Challenges And Prospects, Oitshepile M. Modise, Rebecca Nthogo Lekoko, Olekae Tsompi Thakadu, Masego Ayo Mpotokwane

Human–Wildlife Interactions

Human–wildlife conflicts are increasing globally. The increase in conflicts has been attributed to growing human and wildlife populations and a per capita increase in the consumption of natural resources. In Botswana, conflicts between humans and elephants (Loxodonta africana) are increasing. The growing human population (2.2 million) is encroaching on the animals’ already restricted range. Concomitantly, more elephants are adversely affecting arable agriculture production. To better understand the magnitude and intensity of human–wildlife interactions with elephants and other native wildlife species in Botswana, we collected data through community forum conducted July 17–18, 2017 at a “Kgotla” meeting in Mmadinare, a village …

Canid Vs. Canid: Insights Into Coyote-Dog Encounters From Social Media, Erin E. Boydston, Eric S. Abelson, Ari Kazanjian, Daniel T. Blumstein Jan 2018

Canid Vs. Canid: Insights Into Coyote-Dog Encounters From Social Media, Erin E. Boydston, Eric S. Abelson, Ari Kazanjian, Daniel T. Blumstein

Human–Wildlife Interactions

While the relationship between coyotes (Canis latrans) and house cats (Felis catus) may be characterized as one between predators and their prey, coyote interactions with domestic dogs (C. lupus familiaris) appear to be more varied and may include behaviors associated with canid sociality. While encounters between coyotes and dogs are difficult to observe, we capitalized on publically available video recordings of coyote-dog encounters to observe canid behaviors and examined 35 video clips downloaded from YouTube during fall 2014. We identified coyote-dog interactions that were playful, agonistic, or predatory; those that we could not clearly …

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 …

Can The Vaquita Be Saved From Extinction?, Gerardo Rodríguez-Quiroz, Wenceslao Valenzuela-Quiñonez, Héctor A. González-Ocampo, Alfredo Ortega-Rubio

Human–Wildlife Interactions

The vaquita (Phocoena sinus) is considered the world’s most endangered marine mammal. It is the smallest member of the porpoise family endemic to the upper part of the Gulf of California. The current population is estimated at less than 30 individuals. The primary reasons for the species decline includes limited habitat and incidental mortalities associated with illegal gillnet fishing activities. Since 2008, the Mexican government has taken environmental and economic actions to protect the vaquita’s focusing in reducing by-catch deaths to zero. In 2015, a federal Agreement decreed by the Secretaría de Agricultura, Ganadería, Desarrollo Rural, Pesca y …

Portable Electric Fencing For Bear Deterrence And Conservation, Tom S. Smith, Bryan Hopkins, John Gookin, Samantha Thompson

Human–Wildlife Interactions

Although bear-inflicted (Ursus spp.) human fatalities are rare in North America, human injuries, property damage, and bear mortalities occur wherever bears and humans commingle. We investigated the efficacy of portable electric fencing systems for bear deterrence under a variety of environmental conditions in the lab and field. Our results showed that the bear deterrent systems we evaluated were effective in protecting humans, their food, and property from bears >99% of the time. Herein, we discuss the benefits of using electric fencing, reasons why fences sometimes fail, and provide guidance regarding the most effective implementation of the systems we evaluated. …

Post-Release Activity And Habitat Selection Of Rehabilitated Black Bears, Patrick J. Myers, Julie K. Young Jan 2018

Post-Release Activity And Habitat Selection Of Rehabilitated Black Bears, Patrick J. Myers, Julie K. Young

Human–Wildlife Interactions

Despite the long history of wildlife rehabilitation and the abundance of empirical knowledge of the behavior and resource selection of wildlife species, rarely does research bridge these disciplines. Such investigations could be of value to wildlife managers and rehabilitators by revealing the suitability of the habitat at selected release sites, the wild activities, behavior, and fitness of the captive-reared individuals, and ultimately the efficacy of the rehabilitation process. Rehabilitated carnivores warrant specific attention, given that they are wide-ranging and may behave in ways that threaten human safety or interests. We investigated the behavior of orphan, rehabilitated black bear cubs ( …

Sloth Bear Attacks On Humans In Central India: Implications For Species Conservation, Nisha Singh, Swapnil Sonone, Nishith Dharaiya Jan 2018

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 …

Conservation Of Threatened Canada-Usa Trans-Border Grizzly Bears Linked To Comprehensive Conflict Reduction, Michael F. Proctor, Wayne F. Kasworm, Kimberly M. Annis, A. Grant Machutchon, Justin E. Teisberg, Thomas G. Radandt, Chris Servheen

Human–Wildlife Interactions

Mortality resulting from human–wildlife conflicts affects wildlife populations globally. Since 2004, we have been researching conservation issues and implementing a comprehensive program to reduce human–bear conflicts (Ursus spp.; HBC) for 3 small, fragmented, and threatened grizzly bear (U. arctos) populations in the trans-border region of southwest Canada and northwest USA. We explored the temporal and spatial patterns of conflict mortality and found that HBC contributed significantly to the threatened status of these populations by causing decline, fragmentation, and decreased habitat effectiveness. Our program to reduce HBCs primarily included strategic private lands purchased to reduce human density in …

Using Global Positioning System Technology To Manage Human-Black Bear Incidents At Yosemite National Park, Rachel L. Mazur, Ryan M. Leahy, Caitlin J. Lee-Roney, Kathleen E. Patrick

Human–Wildlife Interactions

Managing human–bear (Ursus spp.) incidents is a top management priority in national parks inhabited by bears. Yosemite National Park (Yosemite), located in the Sierra Nevada in California, USA, receives up to 5 million visitors annually. It is also home to 300–500 black bears (U. americanus). Yosemite has an extensive history of black bear research, educational programs, and innovative solutions for reducing human–bear incidents. Despite this, human–bear incidents peaked in 1998 at 1,584. The resulting political fallout led to Yosemite receiving funds to expand its bear management program, including increasing its staffing and garbage pick-up, and improving the …
