History And Future Of Wildlife Damage Management Conference, Daniel J. Decker
History And Future Of Wildlife Damage Management Conference, Daniel J. Decker
Wildlife Damage Management Conference
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. …
The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter
The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter
Wildlife Damage Management Conference
Airports attract large numbers of wildlife primarily because they offer immense tracts of foraging and nesting habitats free from the threat of predation. Border collies can serve as an effective means of wildlife control in these environments by introducing a predator into the ecosystem. Many wildlife dispersal methods seek to imitate predators or the effect of predators and become increasingly ineffective as wildlife habituate to the stimuli. However, border collies are true predators, representing an actual, not perceived, threat to wildlife thereby eliminating the problems of habituation. Six airports and military bases have initiated use of border collies at their …
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
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 …
Survey Of Factors Affecting The Success Of Clemson Beaver Pond Levelers Installed In Mississippi By Wildlife Services, Dale L. Nolte, Seth R. Swafford, Charles A. Sloan
Survey Of Factors Affecting The Success Of Clemson Beaver Pond Levelers Installed In Mississippi By Wildlife Services, Dale L. Nolte, Seth R. Swafford, Charles A. Sloan
Wildlife Damage Management Conference
Clemson beaver pond levelers were developed as a tool to enable land managers to manipulate water flow past beaver (Castor canadensis) dams. Wildlife Services has installed several of these devices in collaboration with landowners. We conducted a survey to determine if we could identify factors that impacted whether the devices were meeting landowner objectives. Fifty percent of the 40 levelers surveyed were still operating and regarded as successful. Factors considered in the survey included management objectives, time since the leveler was installed, watershed characteristics, physical attributes of the stream and of the beaver dam where the leveler was installed, and …
A Comparison Of Grass Covers And Meadow Vole Populations In North Carolina, William T. Sullivan, John G. Vandenbergh
A Comparison Of Grass Covers And Meadow Vole Populations In North Carolina, William T. Sullivan, John G. Vandenbergh
Wildlife Damage Management Conference
Meadow vole (Microtus pennsylvanicus) populations were monitored in an experimental field for three years by mark and recapture in western North Carolina. The field was planted with 3 different species of grasses: Ky 31 fescue (Festuca arundinacea L.), blue grass (Paa protensis L.), and creeping red fescue (Festuca rubra L.). Voles were free to range from grass to grass due to adjacent plots in the design. Vole populations were highest in Ky 31 and blue grass, and lowest in creeping red fescue. Meadow voles strongly preferred Ky 31 fescue, a grass with high moisture content and a growth pattern compatible …
Double-Crested Cormorant Satellite Telemetry: Preliminary Insight, Scott J. Werner, D. Tommy King, David E. Wooten
Double-Crested Cormorant Satellite Telemetry: Preliminary Insight, Scott J. Werner, D. Tommy King, David E. Wooten
Wildlife Damage Management Conference
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 …
Field Evaluation Of A Visual Barrier To Discourage Gull Nesting, Patricia A. Pochop, John L. Cummings, Richard M. Engeman
Field Evaluation Of A Visual Barrier To Discourage Gull Nesting, Patricia A. Pochop, John L. Cummings, Richard M. Engeman
Wildlife Damage Management Conference
Expanding gull populations along the Columbia River have been implicated in depredations to threatened and endangered migrating salmon smolt, depredations to agriculture crops, bird-aircraft strike hazards, nuisance problems, and potential threats to public health. In an effort to develop management methods for controlling gull populations, we tested a visual barrier to discourage gulls from nesting on an island in the Columbia River. The barrier material is a woven black polypropylene fabric that we utilized to take advantage of the gulls' innate predator avoidance mechanisms, by removing their line of sight to approaching terrestrial predators while providing no protection from aerial …
Investigations Of Methods To Reduce Damage By Voles, Gary W. Witmer, A. A. Hakim, Brian W. Moser
Investigations Of Methods To Reduce Damage By Voles, Gary W. Witmer, A. A. Hakim, Brian W. Moser
Wildlife Damage Management Conference
Voles (Microtus spp.), small burrowing rodents, range over much of North America. Populations cycle and achieve peak densities every 3-5 years. This can result in severe damage to various resources: orchards, forest plantings, alfalfa and other crops, ornamentals, lawns, and gardens. A variety of methods are used to reduce vole damage, but there is still a need for new, cost effective, and environmentally benign approaches. We investigated numerous candidate repellents and barriers with indoor vole colonies in soil-filled tanks. Several compounds (blood meal, capsaicin, castor oil, coyote urine, quebracho, and thiram) showed promise as repellents, but only at high concentrations. …
Rejex-It Bird Repellents - Mode Of Action, Peter F. Vogt
Rejex-It Bird Repellents - Mode Of Action, Peter F. Vogt
Wildlife Damage Management Conference
Rejex-it® bird repellents are used to repel birds and reduce bird predation. Rejex- it® represents a long-needed, logical alternative to inhumane bird control methods such as poisoning and shooting. Its effectiveness as a nuisance bird repellant is based on a common, naturally-occurring, component of food that has been designated by the FDA as a "generally recognized as safe" food and fragrance additive. Methyl Anthranilate (MA), the active ingredient in Rejex-it® Bird Repellents, acts as a sensory repellent by irritating the bird's taste buds, skin, and trigeminal chemoreceptors in the beaks, gizzards, eyes, and mucous membranes. Irritation occurs as a result …

Bada Bang, Bada Boom: Dispersal Of Fall Migrating Cormorants To Protect Sportfish On Oneida Lake, New York, Richard B. Chipman, Milo Richmond, Justin T. Gansowski, Ken J. Preusser, Douglas L. Stang, Jeremy Coleman, Dennis Slate
Wildlife Damage Management Conference
The interior population of double-crested cormorants (Phalacrocorax auritus) continues to increase. As a result, conflicts between human interests and cormorants have intensified. The impacts of nesting, roosting, and migrating cormorants include predation at aquaculture facilities, interspecific competition with rare species including common terns (Sterna hirundo), and impacts to private property. In addition, heightened public and scientific debate regarding cormorant impacts on sportfish has accelerated the need for effective, socially acceptable methods for managing local conflicts. In 1998 and 1999, USDA, APHIS, Wildlife Services; the New York State Department of Environmental Conservation; and USGS, New York Fish and Wildlife Research Cooperative …
Capsaicin-Treated Seed As A Squirrel Deterrent At Birdfeeders, Paul D. Curtis, Elizabeth D. Rowland, Gwen B. Curtis, Joseph A. Dunn
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
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 …
Evaluation Of Moderate And Low-Powered Lasers For Dispersing Double-Crested Cormorants From Their Night Roosts, James F. Glahn, Greg Ellis, Paul Fioranelli, Brian S. Dorr
Evaluation Of Moderate And Low-Powered Lasers For Dispersing Double-Crested Cormorants From Their Night Roosts, James F. Glahn, Greg Ellis, Paul Fioranelli, Brian S. Dorr
Wildlife Damage Management Conference
The double-crested cormorant (Phalacrocorax auritus) is the primary avian predator on the southern catfish industry, estimated to cause $5 million in damage per year. To date, the most effective strategy for alleviating cormorant depredations in areas of intensive catfish production is coordinated dispersal of cormorant night roosts with pyrotechnics. Many of these night roosts are located in waterfowl refuges or wetland habitat leased for waterfowl hunting. Thus, there is an increasing concern about the effects of cormorant harassment efforts on waterfowl and other wildlife inhabiting these sites in cypress-swamp habitat. To address the need for a roost harassment device that …
Evaluating Norway Rat Response To Attractant And Repellent Odors To Improve Rodenticide Baiting Effectiveness, Stephen A. Shumake, A. A. Hakim
Evaluating Norway Rat Response To Attractant And Repellent Odors To Improve Rodenticide Baiting Effectiveness, Stephen A. Shumake, A. A. Hakim
Wildlife Damage Management Conference
Control of rodent infestations using acute-rodenticide baiting is frequently fraught with difficulties involving bait-shyness and neophobic effects. To simulate some of the parameters encountered in baiting situations, pre-weighed quantities of Environmental Protection Agency (EPA) standard challenge bait mixture were used as a highly palatable bait base to induce feeding without the need for food deprivation in Wistar-strain laboratory albino rats. Individual animals were tested for attractant effects of 3 odors (rat urine, preputial gland extract, and carbon disulfide) and a natural repellent odor (coyote urine) in an observation area constructed of clear plastic panels containing a central alley and 2 …
Comparison Of Standard And Modified Soft Catch Traps For Capturing Coyotes, Bobcats, And Raccoons, Jan F. Kamler, Chad Richardson, Philip S. Gipson
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
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 non target species. We captured 15 coyotes and 17 bobcats from October 1995 to March 1997. In addition, 23 raccoons, a large non target 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%, …
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
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 …

Is Translocation Effective For Reducing Raptor Strikes?, Laurence M. Schafer
Wildlife Damage Management Conference
From March 1996 to 31 December 1999, Wildlife Services (WS) personnel trapped and relocated 316 raptors from one of the nation's busiest airports: 147 American kestrels (Falco sparverius), 158 red-tailed hawks (Buteo jamaicensis), 5 rough-legged hawks (Buteo lagopus), 4 peregrine falcons (Falco peregrinus), 1 northern harrier (Circus cyaneus), and 1 eastern screech owl (Otus asio). On 1 January 1999, the Federal Aviation Administration sponsored a 2-year study, in conjunction with the National Wildlife Research Center and WS-Illinois, to evaluate the efficacy of raptor relocation at the airport. This study began in September 1999 and (1) monitors the post release activity …
Aversive And Disruptive Stimulus Applications For Managing Predation, John A. Shivik, Daniel J. Martin
Aversive And Disruptive Stimulus Applications For Managing Predation, John A. Shivik, Daniel J. Martin
Wildlife Damage Management Conference
The range expansion and reintroduction of mammalian predators (e.g., wolves , coyotes and bears) coupled with growing disfavor for traditional tools of wildlife management creates an immediate need for alternative, non-lethal, but effective techniques for managing predation on livestock. Scientists at the National Wildlife Research Center are using advanced technology and animal behavior concepts (e.g., aversive and disruptive stimuli) to develop new tools for the prevention of damage by large mammalian predators, and this paper is a review of our pilot studies investigating these techniques. Recently tested tools include behavior contingent disruptive stimulus devices for wolves and coyotes. Experiments indicate …
Bird Damage To Tropical Fruit In South Florida, Eric A. Tillman, Annamaria Van Doorn, Michael L. Avery
Bird Damage To Tropical Fruit In South Florida, Eric A. Tillman, Annamaria Van Doorn, Michael L. Avery
Wildlife Damage Management Conference
In Dade County, Florida, the production of tropical fruit is a major component of the agricultural industry with total sales amounting to $73.5 million in the 1997-1998 season. Two types of fruit in particular, lychee (Litchi chinensis) and longan (Euphoria longana), are rapidly emerging in economic importance with a combined annual value of over $19 million. For many lychee and longan growers, bird damage is perceived to be a significant constraint to production, yet there is no published information on the extent of damage caused by birds. In 1999, we initiated research to identify the bird species responsible for longan …

Gis Use In Oral Rabies Vaccine Programs, Patricia R. Bright, Elizabeth Schmidt, Francois Elvinger, Michelle M. Weisbarth, R. F. Bulley, Cynthia L. Mills
Wildlife Damage Management Conference
Frequent human and domestic animal exposures to rabid wildlife have raised the public's awareness, leading to an increase in the number of wildlife submissions for rabies testing as well as an increase in the number of people requiring post exposure prophylaxis treatment. During 1998 and 1999, the Health and Human Services Department of a densely populated urban/suburban county in Virginia received a total of 955 animal submissions for rabies testing. Wildlife accounted for 714 of the submissions. Seventy-nine of the submitted wildlife were found dead, 445 were killed or euthanized for testing (190 unknown). Of the wildlife submissions,152 (21%) were …
Efforts To Enhance Stakeholder Communications In North Carolina's Wildlife Damage Control Agent System, Peter T. Bromley, Carl W. Betsill
Efforts To Enhance Stakeholder Communications In North Carolina's Wildlife Damage Control Agent System, Peter T. Bromley, Carl W. Betsill
Wildlife Damage Management Conference
In 1995, North Carolina Wildlife Resources Commission (NCWRC) established policy and rules for handling of nuisance wildlife by Wildlife Damage Control Agents (WDCA). The policy required a one-day long training session, culminating in an open book, certification examination. The North Carolina Cooperative Extension Service (NCCES) conducted the training and administered the examination. The certification-training program covered principles of wildlife damage management, wildlife laws and regulations, humane handling of animals and euthanasia, human health risks from exposure to wildlife, professional ethics, and sources of technical information. Between October 1995 and March 2000, 7 certification-training sessions were held and 289 WDCA's were …
Coding Spreadsheets For Intervention Decisions In Wildlife Damage Management, Ray T. Sterner, H. Nicole Lorimer
Coding Spreadsheets For Intervention Decisions In Wildlife Damage Management, Ray T. Sterner, H. Nicole Lorimer
Wildlife Damage Management Conference
Sterner (In press) described the use of a priori, theoretical analyses of crop/resource savings and benefit:cost ratios as a way of making intervention decisions in wildlife damage management. Iterative (1-variable-changed-at-a-time) calculations of these economic indices were computed for the use of zinc phosphide baits to control vole (Microtus spp.) populations in alfalfa (Medicago sativa). Results showed that indices displayed transitive effects -- greater net savings and benefit:cost ratios were related to larger field-size, crop-damage and bait-effectiveness variables, but smaller bait-application fees. Ratios varied between 0.40 and 6.45, with -5-10% vole-caused damage required to produce returns on investments equal to the …
Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz
Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz
Wildlife Damage Management Conference
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 …
Empowering Local Communities To Co-Manage Deer, William F. Siemer, Daniel J. Decker, Lisa C. Chase
Empowering Local Communities To Co-Manage Deer, William F. Siemer, Daniel J. Decker, Lisa C. Chase
Wildlife Damage Management Conference
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 …

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

Community Bat Management, Jerry D. Hassinger, Calvin M. Butchkoski, Harold S. Korber
Wildlife Damage Management Conference
When a house bat colony (primarily Myotis lucifugus) is excluded from a traditional maternity roost, surviving bats add to nearby roosts or access new roosts in other buildings. To prevent this and the potential for attendant nuisance, and to conserve bats, the Pennsylvania Game Commission recommends using one or more bat boxes to attract the displaced colony. The "standard-sized" bat box used in Pennsylvania will house up to 250 little brown bats. This reactive technique has proved useful for managing single, small colonies (<1,000 bats) in rural areas. We are, however, trying a different, proactive technique to manage large colonies or multiple colonies in a community. Newport, PA, for example, has multiple colonies in buildings within 200 meters of riparian habitat along the Juniata River. Over 7,000 bats were counted exiting a single building. To begin the process of managing these bats, the high school conservation club and town leaders were engaged and presented information about the value of bats. Programs were also presented to a school assembly and to the community. As a result, the conservation club was provided with a site at the community's water treatment plant to erect a bat condo. This site is within 1 km of at least 2 large bat colonies in old buildings. The condo is a 2.4 m square box on posts. It's 2.4 m tall with its bottom 3 m above the ground. Inside, 80 sheets of plywood provide roosting crevices for at least 2,500 bats. Supervised by the Wildlife Diversity Section of the Game Commission, the condo was built in late spring, 1999. A chain-link fence helps protect it from vandalism.
A Private Lands Approach To Controlling New Jersey's Deer Population, David Drake
A Private Lands Approach To Controlling New Jersey's Deer Population, David Drake
Wildlife Damage Management Conference
In New Jersey, annual losses from white-tailed deer (Odocoileus virgianianus) depredation to agricultural crops have been estimated as high as $10 million. Additional problems caused by the state's overabundance of deer include increasing vehicle/deer collisions, possible human health concerns regarding increasing incidences of Lyme disease, and a loss of flora and fauna diversity. In an effort to reduce deer numbers and minimize damage, both non-lethal and lethal management practices have been used with limited success. Hunter access to private lands remains the biggest impediment to effective deer management in New Jersey. I propose an incentive-based program to increase lease and …
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
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 ArcView 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 area …
Den Site Selection And Movement Patterns Of Female Raccoons Following Removal And Exclusion From Residences, Anthony J. Denicola, Michael A. O'Donnell
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
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 …
Special Resident Canada Goose Hunting Seasons In Pennsylvania - Management Implications For Controlling Resident Canada Geese, John P. Dunn, Kevin J. Jacobs
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
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 …
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
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 …
