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 …

History And Future Of Wildlife Damage Management Conference, Daniel J. Decker

Wildlife Damage Management Conference Proceedings

The Eastern Wildlife Damage Management (EWDM) Conference was developed (1st conference held in 1983) to focus on people-wildlife interaction issues occurring in the eastern U.S. Developed as a Renewable Resources Extension Act activity, the purpose of the conference was to improve wildlife resource management and increase outputs of agricultural and forestry commodities. A primary planning issue for the 1st EWDM Conference was whether to represent the conference focus as wildlife damage "control" or "management." Control was selected initially, but the title evolved since then to be replaced by "management," reflecting the central role of wildlife conflict mitigation in wildlife management. …

Capsaicin-Treated Seed As A Squirrel Deterrent At Birdfeeders, Paul D. Curtis, Elizabeth D. Rowland, Gwen B. Curtis, Joseph A. Dunn

Wildlife Damage Management Conference Proceedings

Eastern gray squirrels (Sciurus carolinensis) are considered to be a pest by many bird-lovers because they take significant quantities of seed from birdfeeders. None of the available methods of protecting birdseed against squirrels is completely effective. We assessed the efficacy of treating birdseed with capsaicin oleoresin as a means of deterring squirrels. Consumption of treated and untreated whole, black-oil sunflower seed was compared by carrying out one-choice feeding trials at 3 sites near Ithaca, New York, from 11 May to 24 June 1999. The heat strength of the treated seed was 40,000 Scoville Heat Units (SHUs) (2,424 ppm) on the …

Behavioral Observations And Physiological Implications For White-Tailed Deer Treated With Two Different Immunocontraceptives, Gary J. Killian, Lowell A. Miller

Wildlife Damage Management Conference Proceedings

The results of a 6-year behavioral study of white-tailed deer (Odocoileus Virginianus) treated with two immunocontraceptive vaccines, porcine zona pellucida (PZP) and gonadotropin releasing hormone (GnRH) are summarized. Does were immunized late summer and early fall. In November, does were exposed to bucks and observations were made 2-3 times daily for one half hour through the end of February. Does were considered to be in estrus when they were the object of intensive sexual interest by the buck. Compared to controls, PZP-treated does had a significantly lower fawning rate and an increase in the average number of estrous cycles observed …

Special Resident Canada Goose Hunting Seasons In Pennsylvania - Management Implications For Controlling Resident Canada Geese, John P. Dunn, Kevin J. Jacobs

Wildlife Damage Management Conference Proceedings

Special hunting seasons were first implemented in 1992 to help reduce the growth rate of Pennsylvania's rapidly expanding resident Canada goose (Branta canadensis) population. Special seasons timed to occur before and after fall migration were successful in harvesting resident and not migrant Canada geese. Since 1992, September and late season hunting opportunities have been gradually expanded to include the entire state. The special season harvest of resident Canada geese has increased from about 13,000 birds in 1992 to over 68,000 in 1999. Special hunting seasons now account for over 80% of the entire Canada goose kill in Pennsylvania. Despite the …

What Are The Research Needs And Skills Of The Future?, Richard D. Curnow

Wildlife Damage Management Conference Proceedings

One can be a student of Tom Peters, management visionary and futurist, or Gary San Julian, a leader in the academics of wildlife damage management (WDM), but that is not necessary to be impressed and excited by the rapid trends and unpredictable events that are altering how we think about and attempt to manage the nation's precious wildlife resources. Because of the boundless propensity of mankind to develop, inhabit, and alter the landscape, wildlife managers of today and the future require different strategies, tools, and skills than those who did such a fine job of conservation and management in past …

Comparison Of Standard And Modified Soft Catch® Traps For Capturing Coyotes, Bobcats, And Raccoons, Jan F. Kamler, Chad Richardson, Philip S. Gipson

Wildlife Damage Management Conference Proceedings

Capture rates and injury rates of coyotes (Canis latrans), bobcats {Lynx rufus), and raccoons (Procyon lotor) captured in standard No. 3 Soft Catch® traps were compared to those captured in the same trap type modified with the Taos Lightening Spring™ (TLS) double torsion spring. All traps were equipped with Paws-I-Trip™ pan tension devices and were successful in excluding most small nontarget species. We captured 15 coyotes and 17 bobcats from October 1995 to March 1997. In addition, 23 raccoons, a large nontarget species, were captured. Capture rates for coyotes were higher (P < 0.10) in TLS modified traps (92%) than standard traps (27%), whereas capture rates were similar (P > 0.10) for raccoons (85% and 67%, respectively) and …

Empowering Local Communities To Co-Manage Deer, William F. Siemer, Daniel J. Decker, Lisa C. Chase

Wildlife Damage Management Conference Proceedings

Co-management of white-tailed deer (Odocolius virginianus) holds the promise of creating better management programs in many situations, but agencies may be reluctant to encourage co-management if they doubt the capacity of a community to take on management responsibilities, especially on a continuing basis. In Cayuga Heights, New York, the New York State Department of Environmental Conservation worked with Cornell University and Cornell Cooperative Extension to help a community organization create informed public dialogue about local deer management. Using a consensus-building conceptual framework, we analyzed the planning process that created this dialogue. Process participants believed that use of a third party …

Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz

Wildlife Damage Management Conference Proceedings

This paper reviews the basic concepts behind a comprehensive management approach to managing commensal species, and then considers how this approach is applied to bats that live within and about the built environment. Management activities should take into consideration the whole environment in which the target species is active, including the periodic changes that occur within that environment. Comprehensive management includes a clear understanding of: the biology, behavior and ecology of the species to be managed; the environment in which that species is active (especially harborage location); and the appropriate intervention methods used to manage such species. Interventions fall under …

Perceptions Of White-Tailed Deer Abundance And Management Among Hunters And Landowners In Illinois, Craig A. Miller, Paul Shelton

Wildlife Damage Management Conference Proceedings

State wildlife agencies often find themselves between hunters and landowners in managing white-tailed deer. During 1999 the Illinois Department of Natural Resources (IDNR) restricted archery deer harvest in a 5-county region of East-central Illinois to antlered deer only during the first month of the season. Restrictions were due to declining deer populations and increased archery harvest in the 5-county zone. Hunters in adjacent Shelby County claimed they were seeing fewer deer and lobbied both the IDNR and state legislators for inclusion in the restricted zone during the fall 2000 hunting season. We conducted a telephone survey of resident archery deer …

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 …

Den Site Selection And Movement Patterns Of Female Raccoons Following Removal And Exclusion From Residences, Anthony J. Denicola, Michael A. O'Donnell

Wildlife Damage Management Conference Proceedings

Raccoons (Procyon lotor) are one of many wildlife species that have adapted to survive in urban/suburban environments. Classified as a rabies vector species in many eastern states, their disposition after being handled by wildlife specialists is often dictated by this human health concern. Specifically, some states prohibit relocation and mandate that raccoons be released on site or euthanized. Although management using nonlethal means is often preferred by some segments of the human population, several questions remain to be addressed before appropriate agency policies regarding the handling of urban wildlife can be determined. There is little information available regarding the fate …

Resolving Conflicts With Canada Geese: An Animal Welfare Perspective, John Hadidian, Michele Childs, Nancy Perry, Patricia Lane

Wildlife Damage Management Conference Proceedings

The scope and significance of human conflicts with urban and suburban Canada goose populations has been growing rapidly since the mid 1980s. A lack of basic understanding about the biology and ecology of locally abundant goose populations has led, in part, to argument between opposing camps over the appropriate approaches and methodologies to resolve human-goose conflicts. Animal welfare interests have focused on the humaneness of roundup and slaughter programs, and advocated non-lethal approaches coupled with what they view as the more benign population control activity of egg addling. Some traditional wildlife managers have argued that non-lethal approaches have been tried …

Double-Crested Cormorant Satellite Telemetry: Preliminary Insight, Scott J. Werner, D. Tommy King, David E. Wooten

Wildlife Damage Management Conference Proceedings

Migratory paths of North American waterbirds have traditionally been evaluated by relocating birds banded as nestlings. Although over 8,000 banded Double-crested Cormorants (Phalacrocorax auritus) have been recovered in North America since 1923, the movements of wintering and breeding cormorants remain poorly understood. We initiated a satellite telemetry study to determine the annual and regional distributions of 25 cormorants (in each of two study years) captured near primary aquaculture areas in Alabama, Arkansas, Louisiana, and Mississippi. Preliminary data suggest that cormorants generally remained near aquaculture facilities where they were captured, marked, and released. Two cormorants, however, emigrated from primary aquaculture areas …

Urban Crow Roosts - A Nationwide Phenomenon?, W. Paul Gorenzel, Terrell P. Salmon, Gary D. Simmons, Bob Barkhouse, Mark P. Quisenberry

Wildlife Damage Management Conference Proceedings

We conducted surveys of federal officials nationwide and of local officials in California to determine historical and temporal aspects, location, size, and control of American crow (Corvus brachyrhynchos) urban roosts. The national survey consisted of a 2-page questionnaire sent via email to United States Department of Agriculture Wildlife Services state directors representing the lower 48 states. The California survey consisted of a 3-page questionnaire mailed by the League of California Cities to 473 towns and cities and an email inquiry sent to Agriculture Commissioners in 29 counties. In the national survey respondents in 27 of 39 states identified 86 urban …

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. …

Effectiveness Of Anise As A Coyote Lure, Coren P. Jagnow, Russ Mason

Wildlife Damage Management Conference Proceedings

Odors are frequently used to attract coyotes (Canis latrans) to control devices. Coyote olfactory perception is vital to effectively manage depredation of livestock by coyotes because of the importance of volatile cues to this species. Lures are usually chosen to reflect the biological needs of coyotes as well as relying on food-seeking behaviors to elicit attraction. Anise (Illicum verum) was chosen as the stimulus because of its attractiveness to dogs and its common use as an ingredient in animal foods. Plants comprise a large part of coyotes' diets during warm weather; therefore, a plant odor was chosen to find an …

Correlations Between Burrowing Owl And Black-Tailed Prairie Dog Declines: A 7-Year Analysis, Martha J. Desmond, Julie A. Savidge, Kent M. Eskridge

School of Natural Resources: Faculty Publications

Concern over the status of species associated with prairie dog colonies has increased with the recent proposed listing of black-tailed prairie dogs (Cynomys ludovicianus). We monitored burrowing owl (Athene cunicularia) populations and prairie dog densities in 17 black-tailed prairie dog colonies in the Nebraska panhandle between 1990 and 1996. All prairie dog colonies were controlled at least once during the study. We observed a 63% decline in nesting pairs of burrowing owls and significant declines in burrow densities. Results indicated a time lag in owl response to changes in active burrow densities. However, in the later …

Western Rangeland Noxious Weeds: Collecting, Sharing And Using Information, U.S. Department Of Interior, U.S. Department Of Agriculture, Riley Memorial Foundation

All U.S. Government Documents (Utah Regional Depository)

Western rangeland weeds such as yellow starthistle, leafy spurge, Canada thistle and Russian knapweed are causing tremendous losses to agricultural industries, including both crop and livestock production, and to environmental resources on private lands. Concurrently, many public lands managed by federal agencies are being steadily invaded. As a result, these lands held in the public trust are experiencing reductions in commodity yields, recreational opportunities, biodiversity and ecosystem function.
