Using Predator Exclosures To Protect Ground Nests From Red Fox, Ben C. West, Terry A. Messmer, Dominic C. Bachman Jan 2007

Using Predator Exclosures To Protect Ground Nests From Red Fox, Ben C. West, Terry A. Messmer, Dominic C. Bachman

Human–Wildlife Interactions

Nest predation often is cited as a primary cause for low recruitment and subsequent population decline of many ground-nesting bird species. In response, managers and researchers have developed a myriad of techniques to reduce rates of predation on ground nests. Fences to exclude predators from nesting areas have reportedly been a successful, albeit expensive, strategy to reduce predation rates. Although many studies have evaluated the use of exclusionary fences as a management tool, nearly all of these studies have evaluated the impact of fences in terms of nest success rather than by actual fence penetration by predators. Many authors, for …

Comparison Of Sampling Strategies To Estimate Abundance Of Double-Crested Cormorants In Western Mississippi, Aaron T. Pearse, Brian S. Dorr, Stephen J. Dinsmore, Richard M. Kaminski Jan 2007

Comparison Of Sampling Strategies To Estimate Abundance Of Double-Crested Cormorants In Western Mississippi, Aaron T. Pearse, Brian S. Dorr, Stephen J. Dinsmore, Richard M. Kaminski

Human–Wildlife Interactions

We compared 2 sampling strategies designed to estimate abundance of double-crested cormorants (Phalacrocorax auritus, hereafter cormorants) on aquaculture ponds in western Mississippi. Cormorants are a major predator of cultured channel catfish (Ictalurus punctatus) in this region; thus, estimating cormorant abundance is needed to better determine their economic impact. We independently designed a species-specific survey (i.e., cluster sampling) and a general survey (i.e., transect sampling) based on robust probability sampling theory to estimate abundance of this target population. During winters 2002–2003 and 2003–2004, we conducted 8 pairs of surveys and compared estimates of cormorant abundance and associated …


Drive-By Netting: A Technique For Capturing Grebes And Other Diving Waterfowl, Joe N. Caudell, Michael R. Conover Jan 2007

Drive-By Netting: A Technique For Capturing Grebes And Other Diving Waterfowl, Joe N. Caudell, Michael R. Conover

Human–Wildlife Interactions

We describe a new method (drive-by netting) for capturing grebes (Podiceps spp.) and other birds that dive under water to escape capture. We used a floating gill net to capture 203 eared grebes (Podiceps nigricollis) in 20 days in 1999 on the Great Salt Lake (GSL), 652 eared grebes in 41 days on the GSL in 2000, and 409 grebes in 20 days in 2001. Other species captured during the 2000 and 2001 fi eld seasons included 1 western grebe (Aechmophorus occidentalis), 9 ruddy ducks (Oxyura jamaicensis), and 1 Canada goose (Branta …


Deer–Human Conflict And Hunter Access In An Exurban Landscape, Daniel J. Storm, Clayton K. Nielsen, Eric M. Schauber, Alan Woolf Jan 2007

Deer–Human Conflict And Hunter Access In An Exurban Landscape, Daniel J. Storm, Clayton K. Nielsen, Eric M. Schauber, Alan Woolf

Human–Wildlife Interactions

Exurban development (non-metropolitan, residential development) poses unique challenges for wildlife managers through increases in human–wildlife interactions. However, little is known about hunting activity and human attitudes toward white-tailed deer (Odocoileus virginianus) in exurban areas. In 2004, we surveyed exurbanites near Carbondale, Illinois, regarding their experiences with and attitudes toward deer, whose population in the study area was at or above cultural carrying capacity. Deer–vehicle collisions (DVC) were common and a concern for most respondents (84%). However, DVCs were less influential than plant damage in determining landowner tolerance of deer. Only 19% of respondents allowed hunting on their property, …


Evolution Of The Field Of Wildlife Damage Management In The United States And Future Challenges, James E. Miller Jan 2007

Evolution Of The Field Of Wildlife Damage Management In The United States And Future Challenges, James E. Miller

Human–Wildlife Interactions

Through the early twentieth century, people in rural areas of North America either dealt with problems caused by wildlife by killing the problem species, eliminating its habitat, changing crops or husbandry practices, tolerating the damage, or moving to a new area devoid of such problem animals. However, many of these solutions are impractical today with the increase in human populations, the increased expansion of development into previously rural landscapes, the increased fragmentation of land ownership, and the increasing movement of people into metropolitan areas. Because of current local, state, and federal ordinances and regulations, along with the impacts of animal …


A Review Of Shiga Toxin Escherichia Coli And Salmonella Enterica In Cattle And Free-Ranging Birds: Potential Association And Epidemiological Links, Kerri Pedersen, Larry Clark Jan 2007

A Review Of Shiga Toxin Escherichia Coli And Salmonella Enterica In Cattle And Free-Ranging Birds: Potential Association And Epidemiological Links, Kerri Pedersen, Larry Clark

Human–Wildlife Interactions

Cattle are the main reservoir for human infection by pathogenic Escherichia coli and Salmonella enterica. To prevent entry of these foodborne pathogens into the human food chain, management factors at the farm level must be identified and controlled. External sources of contamination, such as birds, should be considered as potential sources of transmission over long distances. In this review, we focus on the epidemiology of infection by E. coli and S. enterica and the consequences of birds acting as disseminators of these pathogens at dairy farms in terms of cattle health and the subsequent effects on human health.

20,25-Diazacholesterol As An Oral Contraceptive For Black-Tailed Prairie Dog Population Management, Paul B. Nash, Carol A. Furcolow, Kimberly S. Bynum, Christi A. Yoder, Lowell A. Miller, John J. Johnston Jan 2007

20,25-Diazacholesterol As An Oral Contraceptive For Black-Tailed Prairie Dog Population Management, Paul B. Nash, Carol A. Furcolow, Kimberly S. Bynum, Christi A. Yoder, Lowell A. Miller, John J. Johnston

Human–Wildlife Interactions

Black-tailed prairie dog (Cynomys ludovicianus) colonies can become overcrowded, and the colonies, landscape, and people affected by them may benefit from controlled populations. Contraception is a method that may be useful, particularly where lethal control is inappropriate or illegal. We investigated if oral administration of 20,25-diazacholesterol (DiazaCon®), an inhibitor of cholesterol and reproductive steroid hormone production, could reduce reproductive success of treated black-tailed prairie dogs in a fi eld trial. Ten treatments of approximately 45-mg DiazaCon per black-tailed prairie dog yielded a 47% reduction of young:adult ratios compared to control sites. Over a 3-month period, desmosterol, a cholesterol …

Land-Use Pattern, Urbanization, And Deer–Vehicle Collisions In Alabama, Anwar Hussain, James B. Armstrong, David B. Brown, John Hogland Jan 2007

Land-Use Pattern, Urbanization, And Deer–Vehicle Collisions In Alabama, Anwar Hussain, James B. Armstrong, David B. Brown, John Hogland

Human–Wildlife Interactions

With the rise in deer–vehicle collisions across the United States, the associated costs also have risen. Increasingly, however, researchers are learning that these collisions are not a random phenomena but follow a systematic pattern. Building on this insight, we explored the role of county characteristics in influencing the pattern and incidence of white-tailed deer- (Odocoileus virginianus) related auto collisions. Using county level data from 1994 to 2003 in Alabama, we tested several data models with the above mentioned factors as covariates. Our results showed that county characteristics, such as (1) having a deer population density (≥31/km2), (2) being …


Perceptions Of Wildlife Damage And Species Conservation: Lessons Learned From The Utah Prairie Dog, R. Dwayne Elmore, Terry A. Messmer, Mark W. Brunson Jan 2007

Perceptions Of Wildlife Damage And Species Conservation: Lessons Learned From The Utah Prairie Dog, R. Dwayne Elmore, Terry A. Messmer, Mark W. Brunson

Human–Wildlife Interactions

The Utah prairie dog (Cynomys parvidens), a federally listed threatened species, causes damage to agricultural operations, yet little incentive exists for private landowners to conserve them. Therefore, we surveyed Utah residents to identify stakeholder attitudes regarding prairie dog management. We assessed how perceptions of wildlife damage affect respondent attitudes regarding conservation among agricultural producers, rural residents, and urban residents. Higher levels of perceived wildlife damage were reported for agriculture respondents (79%) than for urban (20%) or rural (45%) respondents. Compensation for damage caused by Utah prairie dogs was supported by those engaged in agricultural production but not by …


Public Opinion, The Leopold Report, And The Reform Of Federal Predator Control Policy, James W. Feldman Jan 2007

Public Opinion, The Leopold Report, And The Reform Of Federal Predator Control Policy, James W. Feldman

Human–Wildlife Interactions

This paper explores the role of public opinion in a landmark shift in the federal predator control program. In 1963, the Leopold Committee recommended extensive reform in the federal predator control program, predicting that growing public support for the environmental movement would force such a move if the government did not initiate a change. In the years following the publication of the Leopold Report, the U.S. Division of Wildlife Services reformed its predator control program and tried to improve its public image. Meanwhile, both environmentalists and ranchers fought to control public opinion about the issue. The 1972 ban on predacides …


Use Of Snares To Live-Capture Beavers, Lance B. Mcnew Jr., Clayton K. Nielsen, Craig K. Bloomquist Jan 2007

Use Of Snares To Live-Capture Beavers, Lance B. Mcnew Jr., Clayton K. Nielsen, Craig K. Bloomquist

Human–Wildlife Interactions

Wildlife managers, researchers, and nuisance-control operators often require a nonlethal means of capturing beavers (Castor canadensis). Historically, live-capture has relied on enclosure-type traps such as Bailey or Hancock traps. We describe the live-capture of 231 beavers using snares in southern Illinois from 2002 to 2005. Capture success averaged 5.4 beavers/100 trap-nights. Capture success did not differ between sexes (P = 0.57) or age-classes (P = 0.68). We captured most beavers in haul-out slide sets, surface run sets, or channel sets. Recaptures accounted for 28% (n = 65) of all captures. Mortality rate using snares was …

Adaptive And Economic Management Methods For Feral Hog Control In Florida, Richard M. Engeman, Bernice U. Constantin, Stephanie A. Shwiff, Henry T. Smith, John Woolard, John Allen, John Dunlap Jan 2007

Adaptive And Economic Management Methods For Feral Hog Control In Florida, Richard M. Engeman, Bernice U. Constantin, Stephanie A. Shwiff, Henry T. Smith, John Woolard, John Allen, John Dunlap

Human–Wildlife Interactions

Feral hogs (Sus scrofa) negatively impact the environment in most places around the world where they have been introduced into the wild. In many places, hog removal is essential to protect special habitats, in particular, wetlands. This paper describes techniques developed for use in adaptive management approaches to enhance hog removal efforts in Florida, as well as methods to evaluate the economic impacts from hog management. A valuable adaptive management tool that can be an easily applied index to monitor feral hog activity is track plots. This method has been effective for monitoring hog distribution and relative abundance, …


Appreciating Feral Hogs: Extension Education For Diverse Stakeholders In Texas, Dale Rollins, Billy J. Higginbotham, Kenneth A. Cearley, R. Neal Wilkins Jan 2007

Appreciating Feral Hogs: Extension Education For Diverse Stakeholders In Texas, Dale Rollins, Billy J. Higginbotham, Kenneth A. Cearley, R. Neal Wilkins

Human–Wildlife Interactions

Texas harbors the largest population of feral hogs (Sus scrofa) in the United States, with populations estimated at >2 million. Depending on one’s perspective, feral hogs are either a pariah (from the farmer’s standpoint) or a popular sporting animal (from a hunter’s standpoint). As feral hogs increase in range and density, conflicts among stakeholders are sure to increase. Texas Cooperative Extension (TCE) initiated educational programs in 1991 to address concerns regarding the presence and management of feral hogs. Since that time, we have developed various workshops, symposia, and educational materials (e.g., print, videotape, and website) as means of …


A Landscape-Level Survey Of Feral Hog Impacts To Natural Resources Of The Big Thicket National Preserve, Pedro M. Chavarria, Roel R. Lopez, Gillian Bowser, Nova J. Silvy Jan 2007

A Landscape-Level Survey Of Feral Hog Impacts To Natural Resources Of The Big Thicket National Preserve, Pedro M. Chavarria, Roel R. Lopez, Gillian Bowser, Nova J. Silvy

Human–Wildlife Interactions

We conducted a survey of the impact of feral hog (Sus scrofa) on the natural resources of the Big Thicket National Preserve (BTNP), a unit of the National Park Service. We worked in 3 management units: Lance Rosier, Big Sandy, and Turkey Creek. Random stratified sampling was conducted to assess impacts from hog damage on resources by vegetation type at a landscape scale. Landscape features such as topography, soil moisture, soil type, and dominant vegetative cover types were used to predict hog damage. The overall damage to vegetation from hog rooting or wallowing averaged 28% within the 3 …


Range Size, Habitat Use, And Dial Activity Of Feral Hogs On Reclaimed Surface-Mined Lands In East Texas, Robert C. Mersinger, Nova J. Silvy Jan 2007

Range Size, Habitat Use, And Dial Activity Of Feral Hogs On Reclaimed Surface-Mined Lands In East Texas, Robert C. Mersinger, Nova J. Silvy

Human–Wildlife Interactions

During the last decade, surface lignite mines in eastern Texas have experienced damage by feral hogs (Sus scrofa) to reclaimed areas. Specifically, feral hogs have caused damage to plants used in reclamation. In addition to vegetative losses, erosion control problems and water quality impacts have been noted. Big Brown Lignite Mine in Freestone County, Texas, had tried to control feral hogs through year-long trapping, which proved expensive. We hypothesized that hogs were using reclaimed areas only at night and seasonally. If so, knowledge of travel lanes into the mine and seasonal use would help concentrate trapping efforts and …


Influence Of Habitat Patch Characteristics On The Success Of Upland Duck Nests, Jaime E. Jiménez, Michael R. Conover, Raymond D. Dueser, Terry A. Messmer Jan 2007

Influence Of Habitat Patch Characteristics On The Success Of Upland Duck Nests, Jaime E. Jiménez, Michael R. Conover, Raymond D. Dueser, Terry A. Messmer

Human–Wildlife Interactions

When there is a rich guild of nest predators that use different modalities and techniques to locate hidden nests, we hypothesized that no habitat patch characteristic will consistently predict nest success, because if such a characteristic existed then predators would develop a search image based on it and use that characteristic to increase their hunting efficiency for nests. We tested this prediction in the Prairie Pothole region of North Dakota by characterizing the features of 16 habitat patches that contained >1,800 dabbling duck nests. Nest success was monitored during both the early and late nesting season over 2 years. Nest …
