Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field
Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field
Wildlife Damage Management Conference Proceedings
The sprawling communities surrounding cities pose a paradox for wildlife. Suburban habitat, with parks, greenways, and planned open spaces, provide attractive habitat with abundant resources for some wildlife species. Yet the landscape is dominated by human activities and disturbances. Species with little tolerance for human disturbance and habitat changes have difficulty maintaining their populations in suburban environments. Yet more adaptable species flourish in suburban areas where there are less predators, increased food resources, and abundant habitat for cover and raising young. The resulting overabundant wildlife populations pose increasing problems for biologists, wildlife damage practitioners, and the public. Management of urban …
Seven Years Of White-Tailed Deer Immunocontraceptive Research At Penn State University: A Comparison Of Two Vaccines , Lowell A. Miller, Gary J. Killian
Seven Years Of White-Tailed Deer Immunocontraceptive Research At Penn State University: A Comparison Of Two Vaccines , Lowell A. Miller, Gary J. Killian
Wildlife Damage Management Conference Proceedings
PZP and GnRH immunocontraceptive vaccines were each tested in white-tailed deer (Odocoileus virginianus). Vaccination with PZP produced reversible infertility lasting 1 to 4 years. The first two years of active immunization resulted in an 89% reduction in fawning. Reduction in fawning for the 7-year study containing 4 years of no boosting was 72%. PZP immunization resulted in multi-estrus behavior, with contracepted deer returning to estrus up to 7 times. A five year study of GnRH immunization was conducted in both male and female deer. Treatment of does led to reduced fawning rates, reduced estrus behavior and reduced concentrations of progesterone. …
Spatial Movements In Response To Baiting Female White-Tailed Deer, Scott C. Williams, Anthony J. Denicola
Spatial Movements In Response To Baiting Female White-Tailed Deer, Scott C. Williams, Anthony J. Denicola
Wildlife Damage Management Conference Proceedings
A better understanding of the manipulation of white-tailed deer movement patterns in response to bait has implications for future management of increasing suburban herds. We gathered radio telemetry data for 10 female and 1 male deer over a 1-year period with artificial feeding stations activated in spring and fall. Data were triangulated in the computer program Topo!, transferred into home range program CALHOME, and imported into Arc View for analysis. Mean annual home range size was 57.7 ha with mean core area of 8.4 ha. Spatial changes in behavior of all deer were witnessed in response to bait including core …
Landowners' Perceptions Of White-Tailed Deer Damage To Crops In Tennessee, Dawn L. Johnson, J. Mark Fly, Lisa Muller
Landowners' Perceptions Of White-Tailed Deer Damage To Crops In Tennessee, Dawn L. Johnson, J. Mark Fly, Lisa Muller
Wildlife Damage Management Conference Proceedings
We conducted a mail survey to determine Tennessee landowners' perceptions of white-tailed deer (Odocoileus virginianus) damage to crops, their tolerance for damage and the effectiveness of damage control methods. Fifty-five percent of landowners had wildlife damage and 47% had deer damage. The majority had light or moderate damage. The majority of participants who had taken measures to prevent damage used hunting. State-issued depredation permits were rated the most effective method of controlling damage. Although most survey participants did not have substantial deer damage, landowners with serious deer damage problems may need further assistance.
Radio-Telemetry And Geographical Information Systems To Assess Urban Deer Zoonoses, Karmen M. Hollis, Christopher L. Anchor, James E. Chelsvig, Dwayne R. Etter, J. P. Dubey, Richard E. Warner, Laura L. Hungerford
Radio-Telemetry And Geographical Information Systems To Assess Urban Deer Zoonoses, Karmen M. Hollis, Christopher L. Anchor, James E. Chelsvig, Dwayne R. Etter, J. P. Dubey, Richard E. Warner, Laura L. Hungerford
Wildlife Damage Management Conference Proceedings
Urban white-tailed deer (Odocoileus virginianus) populations can influence the epidemiology of many zoonotic diseases because they affect the distribution and abundance of pathogens and vectors. The risk of emerging zoonotic pathogens increases with human populations, as people have closer contact with wildlife in urban environments. We used radio-telemetry to study deer behavior and population dynamics in Chicago, IL. We monitored home-range use and habitat patterns for 43 radio-collared deer from 2 study sites, 1995-1999. Deer serology was conducted to test for various zoonotic diseases, such as babesiosis, encephalitis, and toxoplasmosis for 12 study locations. To analyze potential disease exposures for …
Effects Of Intense Deer Herbivory On The Herbaceous Understory At Trillium Trail, Tiffany Knight, Susan Kalisz, Lisa Smith, Joann Davis
Effects Of Intense Deer Herbivory On The Herbaceous Understory At Trillium Trail, Tiffany Knight, Susan Kalisz, Lisa Smith, Joann Davis
Wildlife Damage Management Conference Proceedings
Due to a synergism of many human-mediated factors, white-tailed deer (Odocoileus virginianus) populations have increased dramatically throughout many forests throughout the northeastern North America over the last 50 years. The increase in deer populations negatively impacts plants through a variety of mechanisms, which can include increased consumption, trampling, and soil compaction. To preserve the plants in our forests, managers need to understand both how increases in the deer population impact the overall plant community as well as the individual plant species within the community. In general, the impact of deer presence on the overall plant community has been studied by …
Overabundant Deer: Better Management Through Research, Dwayne R. Etter, Timothy R. Van Deelen, Daniel R. Ludwig, Karmen M. Hollis, James E. Chelsvig, Richard E. Warner
Overabundant Deer: Better Management Through Research, Dwayne R. Etter, Timothy R. Van Deelen, Daniel R. Ludwig, Karmen M. Hollis, James E. Chelsvig, Richard E. Warner
Wildlife Damage Management Conference Proceedings
Overabundance of white-tailed deer (Odocoileus virginianus) continues to challenge wildlife professionals nationwide, especially in urban settings. Moreover, wildlife managers often lack general site-specific information on deer movements, survival, and reproduction that are critical for management planning. We conducted radio-telemetry research concurrent with deer culling in forest preserves in northeastern Illinois and used empirical data to construct predictive population models. We culled 2,826 deer from 16 forest preserves in DuPage County (1992-1999) including 1,736 from the 10 km2 Waterfall Glen Forest Preserve. We also radio-marked 129 deer from 8 preserves in DuPage and adjacent Cook County (1994-1998). Recruitment was inversely associated …
Conditioning And Habituation Of White-Tailed Deer To Two Common Deterrents, George R. Gallagher, Jennifer L. Peacock, Elizabeth P. Garner, Robert H. Prince
Conditioning And Habituation Of White-Tailed Deer To Two Common Deterrents, George R. Gallagher, Jennifer L. Peacock, Elizabeth P. Garner, Robert H. Prince
Wildlife Damage Management Conference Proceedings
It was hypothesized white-tailed deer {Odocoileus virginianus) could be readily conditioned to 2 commonly used deterrents, Deer-Away® Big Game Repellent (BGR) and blood meal (BM). Plots were randomly assigned BGR, BM and control. Free-ranging deer were initially conditioned to forage for corn at each 49m2 bare earth plots delivered at 0500 hr and 1600 hr by programmable sling-type feeders. Hoof prints were counted within a 3.7m2 sample area of each plot to quantify activity. Following preconditioning, data were collected during 5, 5-day periods. Application of BGR and BM to their respective bare earth plots occurred during periods 2,4 and 5. …
