Temporal Trends In Florida Panther Food Habits, Gretchen Caudill, David P. Onorato, Mark W. Cunningham, Danny Caudill, Erin H. Leone, Lisa M. Smith, Deborah Jansen

Human–Wildlife Interactions

Once on the brink of extinction, the Florida panther (Puma concolor coryi) has reoccupied parts of its extirpated range in southern Florida, USA over the past 20 years, which has largely been attributed to genetic restoration efforts initiated in 1995 to combat inbreeding depression and subsequent deleterious traits. Concurrent to the resurgence, an increase in documented livestock depredation events has heightened concern over human– panther conflicts. We examined 312 stomach content, scat, and feces (large intestine contents) samples collected 1989 to 2014 across the endemic range in southern Florida. We compared frequency of occurrence of prey items in …

Who Takes The Bait? Non-Target Species Use Of Bear Hunter Bait Sites, Ellen M. Candler, William J. Severud, Joseph K. Bump

Human–Wildlife Interactions

Hunting bears (Ursus spp.) over baits is legal in many countries, states, and provinces, but the practice remains a controversial topic among wildlife managers, hunting groups, and the general public. The baits used to attract bears may also provide a pulsed resource on the landscape that can be used by other wildlife species, particularly carnivores. To determine what other species might use bear bait sites, we constructed and monitored 21 bear bait sites with camera traps from August to October 2016 in the western Upper Peninsula of Michigan, USA. The sites mimicked typical American black bear (U. americanus …

Predicting Black Bear Activity At Backcountry Campsites In Bryce Canyon National Park, Utah, Wesley G. Larson, Tom Smith

Human–Wildlife Interactions

Developing the capacity to predict black bear (Ursus americanus; bear) activity in a diversity of habitats will help conserve bear populations and their habitats and minimize human–bear conflicts. This capacity will be particularly important in areas that provide bear habitat and offer backcountry hiking and camping experiences. Bryce Canyon National Park (BRCA), located on the edge of the Paunsaugunt Plateau in southern Utah, USA, provides important bear habitat and offers visitors 12 backcountry campsites. To effectively manage these areas to minimize human–bear conflicts, park managers will need better information about black bear use of these campsites and other …

Population Dynamics And Control Of Exotic South African Oryx In The Chihuahuan Desert, South-Central New Mexico, Louis Bender, Patrick Morrow, Mara Weisenberger, Bryce Krueger

Human–Wildlife Interactions

Introductions of exotic species can benefit certain publics but can also have many unanticipated consequences. South African oryx (Oryx gazella gazella) were introduced into the Chihuahuan Desert on White Sands Missile Range (WSMR), New Mexico, USA to alleviate a perceived lack of large mammal hunting opportunities. Because of conflicts with oryx as the population increased, we modeled population growth and determined survival of radio-collared oryx to identify rates of population increase, limiting factors to population growth, and levels of harvest necessary to control population growth. Following introductions in 1969–1977, oryx significantly increased their range and showed a rate …

The Marin County Livestock Protection Program: 15 Years In Review, Stephanie Larson, Devan A. Mcgranahan, Robert M. Timm

Human–Wildlife Interactions

Predation by wild carnivores challenges livestock producers worldwide. To reduce or offset losses due to predation, a variety of predator control methods and compensation schemes have been developed. In 2001, Marin County, California, USA replaced its U.S. Department of Agriculture Wildlife Services (WS) cooperative predator damage management program with a county-run program that emphasized nonlethal methods for preventing and controlling coyote (Canis latrans) predation on domestic sheep (Ovis aries). This new Livestock Protection Program (LPP) cost-shared with livestock producers’ efforts to improve fencing, obtain and maintain guard animals, and other such nonlethal methods, and initially it …

The Changing Role Of Rodenticides And Their Alternatives In The Management Of Commensal Rodents, Gary W. Witmer

Human–Wildlife Interactions

Rodents cause substantial damage and losses of foodstuffs around the world. They also transmit many diseases to humans and livestock. While various methods are used to reduce damage caused by rodents, rodenticides remain an important tool in the toolbox. However, like all tools, rodenticides have advantages and disadvantages. Several considerations are shaping the future of rodenticide use, including manufacturing and registration costs, concern about toxicity levels and nontarget animal hazards, potential hazards to children, reduced effectiveness of some formulations, and humaneness to the targeted rodents. Many of these disadvantages apply to anticoagulant rodenticides, and their use is being more restricted …

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 …

Effectiveness Of Snap And A24-Automated Traps And Broadcast Anticoagulant Bait In Suppressing Commensal Rodents In Hawaii, Aaron B. Shiels, Tyler Bogardus, Jobriath Rohrer, Kapua Kawelo

Human–Wildlife Interactions

Commensal rodents (invasive rats, Rattus spp.; house mice, Mus musculus) are well established globally. They threaten human health by disease transfer and impact economies by causing agricultural damage. On island landscapes, they are frequent predators of native species and affect biodiversity. To provide managers with better information regarding methods to suppress commensal rodent populations in remote island forests, in 2016 we evaluated the effectiveness of continuous rat trapping using snap-traps, Goodnature^®A24 self-resetting rat traps, and a 1-time (2-application) hand-broadcast of anticoagulant rodenticide bait pellets (Diphacinone-50) applied at 13.8 kg/ha per application in a 5-ha forest on Oahu, …

Numbers Of Human Fatalities, Injuries, And Illnesses In The United States Due To Wildlife, Michael R. Conover

Human–Wildlife Interactions

I reviewed published and unpublished papers, government reports, and websites to estimate how many people are injured or killed each year by wildlife or stricken by a zoonotic disease. Over 47,000 people annually in the United States sought medical attention after being attacked or bitten by wildlife, and approximately 8 people died annually. Most bites were by snakes, birds, rodents, and raccoons (Procyon lotor). Each year, wildlife–vehicle collisions resulted in >59,000 human injuries and >440 human fatalities, while wildlife–aircraft collisions added 16 more injuries and 10 fatalities. I also found that >68,000 people each year sought medical …

Seal And Polar Bear Behavioral Response To An Icebreaker Vessel In Northwest Greenland, Kate Lomac-Macnair, José Pedro Andrade, Eduardo Esteves

Human–Wildlife Interactions

Icebreaker vessels are important scientific tools, enabling access and research within the polar regions of the world, including the High Arctic. These vessels have the potential to overlap with marine mammal habitats in infrequently studied areas. Marine mammal behavioral responses to icebreaker vessel presence and distance at which responses occur are not well documented or understood. During the Petermann 2015 Expedition on the icebreaker Oden, seal and polar bear (Ursus maritimus) data were collected in Petermann Fjord (Northwest Greenland), the adjacent Nares Strait region, and transit to and from Thule, Greenland over 31 days (July 30 to …

Estimating Waterbird Abundance On Catfish Aquaculture Ponds Using An Unmanned Aerial System, Paul C. Burr, Sathishkumar Samiappan, Lee A. Hathcock, Robert J. Moorhead, Brian S. Dorr

Human–Wildlife Interactions

In this study, we examined the use of an unmanned aerial system (UAS) to monitor fish-eating birds on catfish (Ictalurus spp.) aquaculture facilities in Mississippi, USA. We tested 2 automated computer algorithms to identify bird species using mosaicked imagery taken from a UAS platform. One algorithm identified birds based on color alone (color segmentation), and the other algorithm used shape recognition (template matching), and the results of each algorithm were compared directly to manual counts of the same imagery. We captured digital imagery of great egrets (Ardea alba), great blue herons (A. herodias), …

European Starlings Fly Before They Fledge, Jeremiah L. Psiropoulos, Lisa A. Selner

Human–Wildlife Interactions

Aircraft bird strikes are increasing globally. Bird strikes constitute a major human health and safety risk and result in millions of dollars in economic impacts. Invasive avian species, such as the European starling (Sturnus vulgaris; starlings), have been implicated in bird strikes in North America. Because this species is highly adaptive and has been successful at establishing in new areas, such as airports, it is essential that managers better understand the potential risks and how to mitigate them. Herein we present a case study regarding a novel observation of unique starling nesting behavior that may pose a risk …

Tracking Canada Geese Near Airports: Using Spatial Data To Better Inform Management, Ryan J. Askren, Brett E. Dorak, Heath M. Hagy, Michael W. Eiccholz, Brian E. Washburn, Michael P. Ward

Human–Wildlife Interactions

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 …

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 …

Comparing Live-Capture Methods For Nutria: Single- Versus Multiple-Capture Cage Traps, Trevor R. Sheffels, Jacoby Carter, Mark D. Sytsma, Jimmy D. Taylor

Human–Wildlife Interactions

Herbivory and burrowing by nutria (Myocastor coypus) cause substantial ecological and economic damage. Trapping is a common, effective practice for reducing nutria damage; however, trapping approaches must continually be adapted to keep pace with evolving animal welfare and ethical issues and to more effectively target pest species of interest. Our objective was to evaluate the efficacy of 2 nonlethal trap types for nutria: single-capture (SCT) and multi-capture (MCT) cage traps. We established 3 MCTs and 3 SCTs at each of 7 sites on a 10,500-ha mixed-use island located 15 km northwest of Portland, Oregon, USA. We pre-baited using …
