The Eradication Of Bovine Tuberculosis From Infected Wildlife Populations: A New Zealand Scenario, Garry J.E. Knowles, Mark Hunter, Amy Rush May 2005

The Eradication Of Bovine Tuberculosis From Infected Wildlife Populations: A New Zealand Scenario, Garry J.E. Knowles, Mark Hunter, Amy Rush

Wildlife Damage Management Conference

The Animal Health Board (AHB) is the agency responsible for controlling bovine tuberculosis (Tb) in New Zealand. In 2000, the AHB embarked on a strategy designed to reduce the annual period prevalence of Tb infected cattle and farmed deer herds from 1.67% to 0.2% by 2012/13. Under current rules of the Office International des Epizooties (OIE) this would allow New Zealand to claim freedom from Tb. The epidemiology of Tb in New Zealand is largely influenced by wildlife reservoirs of infection and control of Tb vector populations is central to the elimination of Tb from New Zealand's cattle and deer …


Oral Rabies Vaccination - A Progress Report, Dennis Slate, Charles Rupprecht, Mike Dunbar, Robert Mclean May 2005

Oral Rabies Vaccination - A Progress Report, Dennis Slate, Charles Rupprecht, Mike Dunbar, Robert Mclean

Wildlife Damage Management Conference

Oral rabies vaccination (ORV) targeting specific wild Carnivora species has emerged as an integral adjunct to conventional rabies control strategies to protect humans and domestic animals. ORV has been applied with progress toward eliminating rabies in red foxes (Vulpes vulpes) in western Europe and southern Ontario, Canada. Beginning in the 1990's, coordinated ORV was implemented in Texas to contain and eliminate variants of rabies virus in the gray fox (Urocyon cinereoargenteus) and coyote (Canis latrans) and in several eastern U.S. States with the goal of preventing spread of raccoon (Procyon lotor) rabies. …


Fence-Line Interactions Among Farmed And Free-Ranging Cervids: Preliminary Results, Kurt C. Vercauteren, Justin W. Fischer, Robert Pooler, Michael J. Lavelle, Greg Phillips May 2005

Fence-Line Interactions Among Farmed And Free-Ranging Cervids: Preliminary Results, Kurt C. Vercauteren, Justin W. Fischer, Robert Pooler, Michael J. Lavelle, Greg Phillips

Wildlife Damage Management Conference

Occurrences of disease outbreaks within and near captive cervid (mule deer (Odocoileus hemionus), white-tailed deer (Odocoileus virginianus), and Rocky Mountain elk (Cervus elaphus nelsoni)) farms have recently drawn attention to these facilities. Some state wildlife and agricultural agencies have pondered making double fencing mandatory or otherwise increasing regulation of captive operations. Diseases such as Chronic Wasting Disease (CWD) and Bovine Tuberculosis (bovine TB) are a threat to captive and free-ranging cervid populations. Concerns over these and other diseases being transmitted from captive to wild cervids, and vice versa, have increased. In most cases, captive …


Preliminary Serologic Survey Of Selected Diseases And Movements Of Feral Swine In Texas, A. Christy Wyckoff, Scott E. Henke, Tyler Campbell, David G. Hewitt, Kurt Vercauteren May 2005

Preliminary Serologic Survey Of Selected Diseases And Movements Of Feral Swine In Texas, A. Christy Wyckoff, Scott E. Henke, Tyler Campbell, David G. Hewitt, Kurt Vercauteren

Wildlife Damage Management Conference

Feral swine (Sus scrofa) populations occur throughout eastern, central, and southern Texas, and their populations appear to be increasing. Despite their abundance and wide distribution, little is known about their range and interaction with domestic animals. In the last decade the national pork production industry has enforced an eradication program for economically detrimental swine diseases such as pseudorabies and brucellosis. It is hypothesized that feral hogs can be reservoirs that could reintroduce diseases to disease-free domestic swine herds. The objectives of this on-going project are to determine the prevalence of selected swine diseases that exist within feral hog …


Situational And Driver Characteristics Associated With Deer-Vehicle Collisions In Southeastern Michigan, Alix Marcoux, Graham J. Hickling, Shawn J. Riley, Scott R. Winterstein May 2005

Situational And Driver Characteristics Associated With Deer-Vehicle Collisions In Southeastern Michigan, Alix Marcoux, Graham J. Hickling, Shawn J. Riley, Scott R. Winterstein

Wildlife Damage Management Conference

Deer-vehicle collisions (DVCs) create societal impacts throughout the range of white-tailed deer (Odocoileus virginanus). In Michigan reported DVCs increased by nearly 60% between 1992-2003, with current estimates at more than 65,000 DVCs per year and a mean of $2,300 vehicle damage. To better understand where to direct education and information programs, we used Office of Highway Safety Planning (OHSP) data, 2001-2003, to profile driver characteristics and accident situations of DVCs in Washtenaw, Oakland, and Monroe Counties in Michigan. Each county varies in intensity of land use, human and deer densities, and available deer habitat. Deer density in Washtenaw, …


Assessment Of Texas Medical Providers Concerning Rabies Vaccines, Denise M. Ruffino, Scott E. Henke May 2005

Assessment Of Texas Medical Providers Concerning Rabies Vaccines, Denise M. Ruffino, Scott E. Henke

Wildlife Damage Management Conference

Rabies is an important zoonotic disease in Texas and thousands of people each year either request or require rabies prophylaxis because they have 'high risk ' jobs or are exposed to the disease. After experiencing difficulty in receiving rabies prophylaxis from physicians, we conducted a survey of Texas medical providers to assess their knowledge of rabies vaccine procedures and their experience with rabies vaccines. Most providers in Texas (>95% of 297) rarely saw patients for rabies prophylaxis; therefore, providers have minimal, if any, experience with the procedures of acquiring and administering the vaccine. Providers varied greatly in their responses …


Use Of Natural Vegetative Barriers To Limit Expansion Of Black-Tailed Prairie Dog Towns., David F. Terrall, Jonathan A. Jenks, Arthur E. Smith May 2005

Use Of Natural Vegetative Barriers To Limit Expansion Of Black-Tailed Prairie Dog Towns., David F. Terrall, Jonathan A. Jenks, Arthur E. Smith

Wildlife Damage Management Conference

Prairie dog (Cynomys ludovicianus) control has historically consisted of lethal methods to maintain, reduce, or eliminate populations in South Dakota and throughout the species range. Non-lethal methods of control are desired to meet changing management objectives for the black-tailed prairie dog. The use of naturally occurring buffer strips as vegetative barriers may be effective in limiting prairie dog town expansion. The objectives of this study were: 1) to evaluate effective width of vegetative barriers in limiting prairie dog towns expansion in western South Dakota; and 2) to document effect native vegetation height on expansion of prairie dog towns …


Black-Tailed Prairie Dog Colony Dynamics In South Dakota Over A 10-Year Period, Kathleen A. Fagerstone, Howard P. Tietjen, James F. Glahn, Greg L. Schenbeck, Jean Bourassa May 2005

Black-Tailed Prairie Dog Colony Dynamics In South Dakota Over A 10-Year Period, Kathleen A. Fagerstone, Howard P. Tietjen, James F. Glahn, Greg L. Schenbeck, Jean Bourassa

Wildlife Damage Management Conference

Between 1968 and 1978, aerial photography was used to monitor distribution of black-tailed prairie dog (Cynomys ludovicianus) colonies on a 400-square mile area in South Dakota, including parts of Buffalo Gap National Grassland, Pine Ridge Indian Reservation, and Badlands National Monument (now Badlands National Park). Aerial photographs were taken of the study area in 1968 and annually from 1974 through 1978 at a scale of 1:20,000 (1968) and 1:15,840 (1974-1978). Prairie dog colonies were identified on the photographs, outlined, and the outline transferred to USGS topographic maps for colony size measurements. This technique reliably detected changes in prairie …


In-Burrow Application Of Rozol To Manage Black-Tailed Prairie Dogs, Charles D. Lee, Philip S. Gipson, Jeff J. Wilson May 2005

In-Burrow Application Of Rozol To Manage Black-Tailed Prairie Dogs, Charles D. Lee, Philip S. Gipson, Jeff J. Wilson

Wildlife Damage Management Conference

Our experiment demonstrated that black-tailed prairie dogs(Cynomys ludovicianus) will consume rodenticide underground in their burrows. We demonstrated the efficacy of Rozol Pocket Gopher Bait containing the active ingredient chlorophacione (0.005%) 21 days post treatment for managing black-tailed prairie dogs in their burrows in Kansas. Active prairie dog burrows were reduced 90% when 54 grams of Rozol was placed in the burrow without prebaiting. Results indicate use of this toxicant when placed in the burrow can be an effective means of managing prairie dogs. In-burrow application of rodenticides for black-tailed prairie dog management should markedly reduce exposure of birds …

Taking An Endemically Infected Bovine Tb Area Through To Livestock Clearance. A Case Study Of West Taupo, New Zealand, Kevin Nicholas May 2005

Taking An Endemically Infected Bovine Tb Area Through To Livestock Clearance. A Case Study Of West Taupo, New Zealand, Kevin Nicholas

Wildlife Damage Management Conference

The Pest Management Strategy for Bovine Tuberculosis (Tb) in New Zealand aims to achieve efficient freedom from Tb by 2013 and to eradicate the disease from livestock and wildlife. The West Taupo area, in the central North Island of New Zealand, was chronically infected with Tb in both domestic livestock herds (cattle and deer) and within wildlife populations (brushtail possum, ferret, feral deer and pigs). Through the development and implementation of a technically innovative management plan, this area is now approaching Tb free status. The case study/management plan reported here discusses the operational techniques and strategies that were implemented to …


Evaluation Of A New Strategy For Control Of Bovine Tuberculosis In Michigan White-Tailed Deer: Year 1 Progress Report, Stephen Schmitt, Daniel O'Brien, Elaine Carlson, David Smith, Zachary Cooley, Brent Rudolph, Graham Hickling, Graham Nugent, Peter Butchko May 2005

Evaluation Of A New Strategy For Control Of Bovine Tuberculosis In Michigan White-Tailed Deer: Year 1 Progress Report, Stephen Schmitt, Daniel O'Brien, Elaine Carlson, David Smith, Zachary Cooley, Brent Rudolph, Graham Hickling, Graham Nugent, Peter Butchko

Wildlife Damage Management Conference

The State of Michigan is striving to eliminate bovine tuberculosis (Tb) infection among free-ranging white-tailed deer in the northeastern Lower Peninsula of the state. Aggressive reduction in the overall deer population abundance may help to further reduce TB prevalence, but this course of action is unacceptable to many hunters and landowners. Targeted culling of sick deer would likely be far more acceptable to these stakeholders, so in the winter of 2003 the Michigan Department of Natural Resources pilot-trialed a new strategy based on live-trapping and Tb-testing of wild deer. The field study was conducted in a township with relatively high …


Observations On The Use Of The Gnrh Vaccine Gonacon™ In The Male White-Tailed Deer (Odocoileus Virginianus), G. Killian, D. Wagner, L. Miller May 2005

Observations On The Use Of The Gnrh Vaccine Gonacon™ In The Male White-Tailed Deer (Odocoileus Virginianus), G. Killian, D. Wagner, L. Miller

Wildlife Damage Management Conference

Observations made over an 11 year period during the development and evaluation of the GnRH vaccine GonaConTM use in male white-tailed deer (Odocoileus virginianus) are summarized. Sexually mature bucks at the Penn State Deer Research Center were administered a single immunization of GonaConTM in July. Some males were also given a second boost immunization in September. Compared to similar aged controls, testicular size for treated males was considerably reduced in the first and subsequent years of study, as were testosterone concentrations and sexual libido. During the first year, antler development was relatively normal leading to antler …


Management Of Wolf-Livestock Conflicts Of Minnesota, William J. Paul May 2005

Management Of Wolf-Livestock Conflicts Of Minnesota, William J. Paul

Wildlife Damage Management Conference

In 1975, the gray wolf (Canis lupus) population in Minnesota was protected by the federal Endangered Species Act (USA). At that time, there were 500-750 wolves. By 2004, the population had grown to an estimated 3,020 wolves. Over time, conflicts between wolves and livestock increased. Wolf depredation control programs have been conducted by the U.S. Fish and Wildlife Service (1975-1986) and by the U.S. Department of Agriculture's Wildlife Services program (1986 to present). In 1978, Minnesota's wolves were reclassified from endangered to threatened which allowed authorized federal agents to lethally remove wolves that had depredated on livestock or …

Elk In Nebraska: Opportunity Or Another Private-Public Land Conundrum, Scott E. Hygnstrom, Michael A. Cover, Bruce A. Stillings, R. Daniel Crank, Justin W. Fischer, James W. Merchant, Seth P. Korte

Wildlife Damage Management Conference

We conducted a comprehensive research project on elk in the Pine Ridge region of northwestern Nebraska from 1995 to 2002 to determine ecological factors that could be used to improve management and reduce damage. The population ranged from 120 to 150 animals, with an average calf:cow ratio of 0.5:1 and bull:cow ratio of 0.4:1. We located 21 radio-collared female elk 6,311 times during 1995 to 1997. Seasonal home ranges of 2 herds were 10 and 44 km2, while average annual home ranges of the herds were much larger (483 and 440 km2, respectively). All wintering areas …


Badger Movement Ecology In Colorado Agricultural Areas After A Fire, Craig A. Ramey, Jean B. Bourassa May 2005

Badger Movement Ecology In Colorado Agricultural Areas After A Fire, Craig A. Ramey, Jean B. Bourassa

Wildlife Damage Management Conference

While investigating the American badger (Taxidea taxus) in eastern Colorado' s wheatlands, we studied 3 badgers which were affected by a 2.1 km2 man-made fire and compared them to 2 adjacent badgers unaffected by the fire. All badgers were equipped with radio-telemetry collars and generally located day and night for approximately 1 month pre-fire and 3 weeks post-fire. Three point triangulation locations were converted into a global information system database. Adaptive kernel analyses compared pre- and post-fire horizontal: home ranges (i.e. 95% utilization areas, UAs), core activity areas (50% UAs), movements, den and habitat use patterns. Mean …


Challenges Of Invasive Reptiles And Amphibians, William C. Pitt, Daniel S. Vice, Mike E. Pitzler May 2005

Challenges Of Invasive Reptiles And Amphibians, William C. Pitt, Daniel S. Vice, Mike E. Pitzler

Wildlife Damage Management Conference

Although worldwide distributions of many amphibians and reptiles are declining, a handful of species are spreading rapidly throughout tropical regions of the world. The species that have the greatest effect tend to be generalist feeders, have high reproductive rates, attain large population sizes, and often due to their behavior and or small size, are easily transported or are difficult to detect. The most notable of these species include the coqui frog, cane toad, bullfrog, brown tree snake, and Burmese pythons. The effect of a few individuals typically is small but the combined effect of large populations can be devastating to …


Initial Development Of A Web-Based Tool To Increase Hunter Harvest Of Female Ungulates, James E. Knight, Marc Kenyon, Linda Keddington May 2005

Initial Development Of A Web-Based Tool To Increase Hunter Harvest Of Female Ungulates, James E. Knight, Marc Kenyon, Linda Keddington

Wildlife Damage Management Conference

Landowners and agencies have expressed difficulty finding hunters willing to harvest the female portion of the ungulate populations, and likewise, hunters have expressed difficulty achieving access to private lands. Since 2003, the Montana "DoeCowHunt" website (www.doecowhunt.montana.edu) has provided an avenue to improve hunter-landowner contact and wild ungulate population management. A product of Montana State University Extension Wildlife Program, this website provides a means for hunters and landowners in Montana to contact each other by listing contact information (email address, physical address, and telephone number) for the purpose of harvesting antlerless ungulates. In the first year over 10,000 users visited the …
