Morbidity And Mortality In Reptiles Presented To A Wildlife Care Facility In Central Illinois, Anne E. Rivas, Matthew C. Allender, Mark Mitchell, Julia K. Whittington
Morbidity And Mortality In Reptiles Presented To A Wildlife Care Facility In Central Illinois, Anne E. Rivas, Matthew C. Allender, Mark Mitchell, Julia K. Whittington
Human–Wildlife Interactions
We examined morbidity and mortality of 200 reptiles, representing 13 different species that were presented to the University of Illinois Wildlife Medical Clinic (WMC) from 2003 to 2010. Snapping turtles (Chelydra serpentine; n = 46), box turtles (Terrapene sp.; n = 43), painted turtles (Chrysemys picta; n = 37), and red-eared slider turtles (Trachemys scripta elegans; n = 33) were the most frequently seen species. Turtles were significantly more likely to be presented to the WMC following collision with a motor vehicle (n = 73) than any other reason, including idiopathic trauma (i.e., …
An Evaluation Of Two Traps And Sets For Trapping The Plains Pocket Gopher, Stephen M. Vantassel, Andrew J. Tyre, Scott E. Hygnstrom
An Evaluation Of Two Traps And Sets For Trapping The Plains Pocket Gopher, Stephen M. Vantassel, Andrew J. Tyre, Scott E. Hygnstrom
Human–Wildlife Interactions
We investigated the efficiency of DK-1 and Macabee® pocket gopher (Geomys bursarius) traps placed in lateral tunnels in both open and closed tunnel sets in rangeland and nonirrigated alfalfa fields in Nebraska. We observed no statistical difference between the traps in capture efficiency when used in open, versus closed, tunnel sets. Trapping of pocket gophers was more effective in rangeland (probability of capture in a single tunnel system using 3 traps; 63%) than nonirrigated alfalfa fields (26%). We did not determine whether this variance was due to behavioral differences between Geomys bursarius and Geomys lutescens. We found …
A Spatially Explicit Model Of The White-Tailed Deer Population In Delaware, Brian Jennings, Jacob L. Bowman, Elizabeth L. Tymkiw
A Spatially Explicit Model Of The White-Tailed Deer Population In Delaware, Brian Jennings, Jacob L. Bowman, Elizabeth L. Tymkiw
Human–Wildlife Interactions
Population models of white-tailed deer (Odocoileus virginianus) are used by many states to predict population levels and aid in making management decisions. Delaware did not have a deer population model, so we developed one and used it to investigate the implications of changes to the harvest. We modeled 7 changes to the harvest regime and compared these changes to the base line of no changes to the harvest regime. We used survival rates, reproductive rates, harvest data, a population estimate, and spotlight counts to construct the model. The model scenario began in February 2006 and ran until August …
Examining Patterns Of Animal–Vehicle Collisions In Alabama, Usa, Xiongwen Chen, Shuhong Wu
Examining Patterns Of Animal–Vehicle Collisions In Alabama, Usa, Xiongwen Chen, Shuhong Wu
Human–Wildlife Interactions
Animal–vehicle collisions (AVCs) cause animal death, human injury, and vehicle damage. Uncovering the general patterns and related ecological processes of AVCs is useful for developing mitigation strategies. We examined some previous patterns about AVCs from records in Alabama during 2001 to 2011. The results confirm that: (1) there was a seasonal pattern, with >50% of AVCs occurring in winter; (2) AVCs occurred most frequently at dawn and dusk in the diurnal pattern; and (3) most AVCs occurred on county highways. However, interstate and federal highways had higher numbers of AVCs per km of road. Counties within metropolitan areas had more …

Testing Systems Of Avian Perch Deterrents On Electric Power Distribution Poles In Sage-Brush Habitat, James F. Dwyer, Kerrin W. Doloughan
Testing Systems Of Avian Perch Deterrents On Electric Power Distribution Poles In Sage-Brush Habitat, James F. Dwyer, Kerrin W. Doloughan
Human–Wildlife Interactions
In Lincoln County, Washington, USA, greater sage-grouse (Centrocercus urophasianus) and Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) are managed as reintroduced and augmented populations, respectively. Predation by raptors and corvids is a concern, particularly where utility poles may provide hunting perches near leks (i.e., breeding areas). Perch deterrents may offer a mitigating strategy if deterrents reduce the frequency or duration of perching. To investigate the effects of various perch deterrents, we deployed deterrents on 5 power poles retained for use in this study when 33 poles were removed from occupied grouse habitat. We rotated deterrents among poles every 15 to 28 …
Evaluation Of Foliar Sprays To Reduce Crop Damage By Canada Geese, Charles D. Dieter, Cody S. Warner, Curiong Ren
Evaluation Of Foliar Sprays To Reduce Crop Damage By Canada Geese, Charles D. Dieter, Cody S. Warner, Curiong Ren
Human–Wildlife Interactions
South Dakota Department of Game, Fish and Parks annually spends >$500,000 managing crop damage caused by grazing Canada geese (Branta canadensis). Foliar applications of a chemical feeding deterrent could provide an effective alternative to the methods currently being used to reduce damage. In 2011 and 2012, we evaluated Rejex-It Migrate Turfguard®, Bird Shield®, Avian Control®, and Avipel® as grazing deterrents. We used a ground sprayer to apply the treatments every 7 days to plots in soybean fields in Day County, South Dakota. We monitored activity in the plots using time-lapse photography. We began treating the plots after geese …
Identifying People’S Most Preferred Management Technique For Feral Cats In Hawaii, Cheryl A. Lohr, Christopher A. Lepczyk, Linda J. Cox
Identifying People’S Most Preferred Management Technique For Feral Cats In Hawaii, Cheryl A. Lohr, Christopher A. Lepczyk, Linda J. Cox
Human–Wildlife Interactions
Feral cats (Felis catus) are abundant in many parts of the world and pose a threat to native wildlife. Human–wildlife conflicts regarding how feral cats should be managed have increased recently. In Hawaii, previous research has revealed that most residents would like to see the feral cat abundance reduced, but opinions differ regarding which techniques are acceptable for achieving this. This paper describes an analytical hierarchy process that combines rankings of decision criteria by Hawaii’s residents with expert knowledge of the costs and benefits associated with 7 techniques (live-capture and adoption, live-capture and lethal injection, live-capture and lethal gunshot, trap-neuter-release …

Regulation Of Tree Squirrel Populations With Immunocontraception: A Fox Squirrel Example, Sara K. Krause, Douglas A. Kelt, Dirk H. Van Vuren, James P. Gionfriddo
Human–Wildlife Interactions
Tree squirrels (Sciurus spp.) are highly successful immigrants to urban and suburban areas in North America and Europe, causing both economic and ecological damage. Control of such invasive populations is challenging but of increasing importance to local managers. We studied an invasive population of fox squirrels (S. niger) and applied an immunocontraceptive vaccine in an experimental study of demographic control. Here we integrate our data into a simple stage-structured population model to simulate population reduction under 2 treatment levels (60 and 80% of females, respectively) for vaccines lasting from 1 to 5 years. Contraception can be an effective …

Wildlife Strikes With U.S. Military Rotary-Wing Aircraft Deployed In Foreign Countries, Brian E. Washburn, Paul J. Cisar, Travis L. Devault
Human–Wildlife Interactions
During recent decades, rotary-wing aircraft (helicopters) within the U.S. Department of Defense (e.g., U.S Army and U.S. Air Force) have been deployed overseas to conduct a variety of noncombat and combat missions. Our objective was to conduct a comprehensive analysis of wildlife (birds, bats, insects) strikes with U.S. Army and U.S. Air Force rotarywing aircraft during overseas deployments. We acquired all available wildlife strike information involving U.S. Army and U.S. Air Force military rotary-wing aircraft engaged in flight operations associated with U.S. military bases around the world during 1990 to 2011. Wildlife strikes with military rotary-wing aircraft occurred in >31 …

Nuisance American Alligators: An Investigation Into Trends And Public Opinion, Cord B. Eversol, Scott E. Henke, Jacob L. Ogdee, David B. Wester, Amos Cooper
Human–Wildlife Interactions
The population rebound of the American alligator (Alligator mississippiensis; hereafter, alligator), with the rapid growth of populations throughout its range, has caused an influx of human–alligator conflicts. We quantified 5,838 nuisance alligator reports from 2000 to 2011 to develop more site-specific strategies of management and to determine where management should be focused to minimize the conflict. We also surveyed the general public’s attitude toward and knowledge of alligators (n = 98) as a technique to better understand human dimensions of nuisance alligator management in Texas. Counties that received the largest numbers of nuisance alligator reports were Jefferson (16%), Fort Bend …

Reducing The Potential For Human–Snake Encounters In A Recreational Park, Evin T. Carter, Omar Attum, Bryan C. Eads, Andrew S. Hoffman, Bruce A. Kingsbury
Human–Wildlife Interactions
Parks and outdoor recreation areas often struggle to balance management for outdoor recreation with the protection of native flora and fauna. Additional complications can arise for land managers when recreation occurs in areas shared with wildlife that are perceived by humans to be dangerous. Despite these issues, many parks may inadvertently increase the potential for human–wildlife encounters through the creation of artificial forest gaps used for recreational purposes. We determined the potential for human encounters with venomous copperhead snakes (Agkistrodon contortrix) at a recreational park in southern Indiana before and after several simulated closures of recreational forest gaps. …
Effects Of Removal On A Lightly Exploited Coyote Population In Eastern Nevada, Patrick J. Jackson
Effects Of Removal On A Lightly Exploited Coyote Population In Eastern Nevada, Patrick J. Jackson
Human–Wildlife Interactions
Coyote (Canis latrans) removal is a common, yet controversial, management practice to increase game populations throughout the West. I studied the effect of removal on coyote populations in eastern Nevada from 2004 to 2008 and reviewed 27 available publications to determine the level of human exploitation on my study populations. Removals were performed by USDA Wildlife Services (WS) to benefit game populations and involved the use of trapping, neck snaring, and ground and aerial shooting. To determine if the removal had an effect on the coyote populations, I measured 3 parameters: the presence or absence of skewed sex …

Effectiveness Of A Simulated Pack To Manipulate Wolf Movements, Christine M. Anhalt, Timothy R. Van Deelen, Ronald N. Schultz, Adrian P. Wydeven
Human–Wildlife Interactions
Bioboundaries, also called biofences, are deterrents that attempt to exploit certain innate behaviors to exclude wildlife from target areas. We hypothesized that human-deployed scent marks and playbacks of foreign howls could simulate a territorial gray wolf (Canis lupus) pack impinging on a resident pack, thereby causing the resident pack to move. During summer 2010, we deployed a simulated-pack bioboundary near 3 wolf packs in northern Wisconsin and monitored their movements relative to 3 wolf packs experiencing a sham treatment, to control for effects of human presence. We analyzed wolves’ locations (≥1 location per week) and used linear models …

Efficacy Of Ropel® As A Coyote Repellent, Elizabeth A. Miller, Julie K. Young, Scott Stelting, Bruce A. Kimball
Human–Wildlife Interactions
We examined the repellency of a commercially available animal repellent to determine the efficacy of its application to objects that are attractive to coyotes (Canis latrans). Specifically, we aimed to both prevent chewing behavior by coyotes on a nylon-like strapping material, which is used to construct barrier-arresting systems on military airstrips, and determine the ability of the solution to prevent the animals from repeating the undesired behavior. We mixed Ropel® Animal and Rodent Repellent with a liquid latex sticker to form a 2% latex and 98% Ropel solution. We used a 2% latex and 98% water solution as …

Integrating Mammalian Hazards With Management At U.S. Civil Airports: A Case Study, Kristin M. Biondi, Jerrold L. Belant, James A. Martin, Travis L. Devault, Guiming Wang
Human–Wildlife Interactions
Wildlife incidents with U.S. civil aircraft cost an estimated $1.4 billion from 1990 to 2010, with mammals 5 times more likely to cause damage than other wildlife. We surveyed 2 general aviation (GA) airports and 6 Part-139 certificated (i.e., certified) airports to assess efficacy of management practices for mammalian species hazardous to aircraft. We obtained information on mammalian species present on airport grounds, types and estimated effectiveness of management techniques, and effort spent on wildlife management. We evaluated management techniques relative to aircraft–wildlife collisions (i.e., incident) frequencies taken from Federal Aviation Administration’s (FAA) National Wildlife Strike Database and species hazard …
Soil Quality Manipulation To Reduce Bird Presence At Airports, Theresa K. Johnston, Bruce Branham, Jeffrey Brawn
Soil Quality Manipulation To Reduce Bird Presence At Airports, Theresa K. Johnston, Bruce Branham, Jeffrey Brawn
Human–Wildlife Interactions
Aviation safety is an important concern in wildlife management as bird strikes risk human lives and result in costly damage. Habitat management can decrease bird abundances locally at airports. We tested soil manipulation as a technique to reduce local bird presence by establishing experimental plots with either intact topsoil or “stripped” subsoil with the aim of decreasing foraging substrate for birds. We estimated invertebrate abundance, and observed bird presence from 2006 to 2008. More birds visited topsoil plots (151.5 birds/ ha/hour) than subsoil plots (72.7 birds/ha/hour). Topsoil plots supported a greater biomass of invertebrates than subsoil plots ( = 0.39 …
Population Trends Of Resident And Migratory Canada Geese In Relation To Strikes With Civil Aircraft, Richard A. Dolbeer, John L. Seubert, Michael J. Begier
Population Trends Of Resident And Migratory Canada Geese In Relation To Strikes With Civil Aircraft, Richard A. Dolbeer, John L. Seubert, Michael J. Begier
Human–Wildlife Interactions
Canada geese (Branta canadensis) are of particular concern to aviation in the USA because of their large size, flocking behavior, attraction to airports for grazing, and, for the resident population, year-round presence in urban environments. We documented trends in resident and migrant Canada goose populations in North America from 1970 to 2012, and for 1990 to 2012 examined these trends in relation to trends in reported civil aircraft collisions (strikes) with Canada geese. The overall Canada goose population increased 4.5 fold from 1.26 million in 1970 to 5.69 million in 2012. Most of this overall increase was due …

Human–Wildlife Interactions
China is one of the largest consumers of wild animals for food and traditional Chinese medicine in the world. A large volume of illegal trade has been recorded in the primary cities, such as Hong Kong and Guangzhou, but the wildlife markets in secondary Chinese cities have not been investigated. This study was carried out in 7 cities in Guangdong and Guangxi provinces. Wildlife trade data were collected using semi-structured interview, observation, and market survey. The study documented the selling of 97 animal species, >7,000 individuals. The most frequently used animal groups by quantity were reptiles (51%), followed by birds …
Evaluation Of Eight Repellents In Deterring Eastern Cottontail Herbivory In Connecticut, Scott C. Williams, Michael R. Short
Evaluation Of Eight Repellents In Deterring Eastern Cottontail Herbivory In Connecticut, Scott C. Williams, Michael R. Short
Human–Wildlife Interactions
Herbivory by eastern cottontails (Sylvilagus floridanus) can be the source of significant agricultural, nursery, and managed landscape damage. Where cottontails cannot be managed by lethal means or where trap and release is infeasible, repellents may be a reasonable alternative. We tested 8 different repellent formulations (Bobbex Deer Repellent® Canadian formulation concentrate, Bobbex Deer Repellent® Canadian ready-to-use (RTU), Bobbex-R Animal Repellent® concentrate, Bonide Repels All® concentrate, Bonide Deer & Rabbit Repellent® concentrate, Liquid Fence® Deer & Rabbit Repellent concentrate, Plantskydd® soluble powder, and Rabbit Stopper® RTU) on Johnny jump-ups (Viola tricolor), lettuce (Lactuca sativa), and …

The Centers for Disease Control (CDC) and USDA Wildlife Services (WS) have been involved in an oral rabies vaccination (ORV) program for raccoons (Procyon lotor) that has slowed the westward spread of raccoon rabies. The objective of this study was to forecast the spread of the disease if an ORV zone was not maintained. A group decision-making process was designed to address the forecasting problem and was implemented using a group of 15 experts and 4 support personnel at a meeting at the USDA National Wildlife Research Center. Ten expansion regions were constructed that described the spread of …

Oil And Gas Impacts On Wyoming’S Sagegrouse: Summarizing The Past And Predicting The Foreseeable Future, Dave H. Applegate, Nick L. Owens
Human–Wildlife Interactions
Historical impacts from oil and gas development to greater sage-grouse (Centrocercus urophasianus) habitat are well-documented in some areas of Wyoming, in particular within natural gas development fields, such as the Powder River Basin and JonahPinedale. The drilling techniques and pad densities in these fields have been extrapolated to estimate future oil and gas impacts in the U. S. Fish and Wildlife Service (2010) warranted-but-precluded listing determination for the sage-grouse under the Endangered Species Act. Further, assumptions regarding the scale of oil and gas development are incorporated within various resource management plan amendments by the Bureau of Land Management …

Farmers’ Perceptions Of The Impacts Of Human– Wildlife Conflict On Their Livelihood And Natural Resource Management Efforts In Cheha Woreda Of Guraghe Zone, Ethiopia, Dagne Mojo, Jessica Rothschuh, Mehari Alebachew
Human–Wildlife Interactions
There are several livelihood improvement and natural resource management campaigns being undertaken in Ethiopia. In Cheha Woreda District of Guraghe Zone, a research team from the Ethiopian Institute of Agricultural Research, Holetta Research Center, is undertaking a watershed-level intervention to improve sustainable land management practices among resident agrarian families. In 2011, a household survey was conducted to assess farmers’ perceptions of human–wildlife conflicts (HWC) and the effects of these conflicts on land management in Cheha Woreda. One-hundred randomly selected households in the Cheha Woreda were asked to identify any wild or domestic animals that cause damage to their crops. Additionally, …

Influence Of Egg Oiling On Colony Presence Of Ring-Billed Gulls, Travis L. Devault, Paige M. Schmidt, Fred E. Pogmore, John Gobeille, Jerrold L. Belant, Thomas W. Seamans
Human–Wildlife Interactions
Egg oiling is a form of management in which bird eggs are coated with mineral or corn oil, preventing gas exchange through the shell and killing embryos. Unlike other nest disturbance techniques, egg oiling reportedly precludes colony abandonment and, thus, can be advantageous when managers wish to limit dispersal within the breeding season to other locations while stabilizing the population or reducing productivity. However, unintended, indirect effects of egg oiling are not well-characterized. We evaluated the influence of egg oiling on ring-billed gulls (Larus delawarensis) within the Lake Champlain basin, Vermont, during the nesting season to determine whether egg oiling …

Characteristics And Distribution Of Live-Stock Losses Caused By Wild Carnivores In Maasai Steppe Of Northern Tanzania, Batistino P. Mponzi, Christopher A. Lepczyk, Bernard M. Kissui
Human–Wildlife Interactions
Agricultural development accelerates the loss of habitat for many wildlife species and brings humans and animals in close proximity, resulting in increased human–wildlife conflict. In Africa, such conflicts contribute to carnivore population declines in the form of human retaliation for livestock depredation. However, little knowledge exists about when and where carnivores attack livestock. Given this need, our objectives were to (1) understand the spatial and temporal variation of human–carnivore conflict and (2) identify conflict-prone areas. We addressed these objectives in 18 Tanzanian villages of the Maasai Steppe using livestock depredation data on lions (Panthera leo), spotted hyenas ( …
