The Need To Address Black-Backed Jackal And Caracal Predation In South Africa, David L. Bergman, Ho De Waal, Nico L. Avenant, Michael J. Bodenchuk, Michael C. Marlow, Dale L. Nolte Jan 2013

The Need To Address Black-Backed Jackal And Caracal Predation In South Africa, David L. Bergman, Ho De Waal, Nico L. Avenant, Michael J. Bodenchuk, Michael C. Marlow, Dale L. Nolte

Wildlife Damage Management Conference Proceedings

Prior to 1990, the four provincial governments of South Africa had a variety of programs in place to manage predation by black-backed jackals and caracals through lethal and nonlethal manage-ment in close cooperation with livestock farmers. During the 1990s the official programmes were phased out due to a multitude of factors including lower predation rates. Today, thousands of livestock (primari-ly sheep and goats, but also cattle and wildlife) are lost each day in South Africa due to black-backed jackal and caracal predation. The actual numbers are not known because not all losses are accounted or reported. It also does not …


Suburban Coyote Management And Research Needs: A Northeast Perspective, Paul D. Curtis, Daniel A. Bogan, Gordon Batcheller Apr 2007

Suburban Coyote Management And Research Needs: A Northeast Perspective, Paul D. Curtis, Daniel A. Bogan, Gordon Batcheller

Wildlife Damage Management Conference Proceedings

Several factors may be responsible for increasing predator abundance in suburbia. These include an enhanced forage base associated with residential sprawl, and protection of predator species that were once persecuted and suppressed by hunters, trappers, and landowners. In the Northeast, anecdotal reports of coyotes (Canis latrans) killing pets in backyards are on the rise. The bulk of coyote complaints, concerns, and questions received from the public by state wildlife agencies are from areas with high human populations. Scant research exists on coyote behavioral ecology in human-altered landscapes. Biologists and managers need to understand changes in the social structure …


Ecology Of Coyotes In Urban Landscapes, Stanley D. Gehrt Apr 2007

Ecology Of Coyotes In Urban Landscapes, Stanley D. Gehrt

Wildlife Damage Management Conference Proceedings

Coyotes (Canis latrans) have become common in many metropolitan areas across the United States. Recent research has focused on the urban ecology of coyotes to better our understanding of how they exist in urbanized landscapes. I summarize findings from a variety of ecological studies of coyotes in or near metropolitan areas, and focus on three areas of coyote ecology: survival rates, home range/activity, and food habits. Most studies have reported relatively high survival rates (annual S = 0.62 - 0.74), with vehicle collisions often a common cause of mortality. Size of coyote home ranges (mean home range sizes …


Coyotebytes.Org: A New Educational Web Site, Robert M. Timm Apr 2007

Coyotebytes.Org: A New Educational Web Site, Robert M. Timm

Wildlife Damage Management Conference Proceedings

A web site, www.CoyoteBytes.org, has been developed as a tool to provide sciencebased management recommendations to homeowners and municipal officials on methods to reduce conflicts with coyotes (Canis latrans) in urban and suburban areas. Such conflicts include aggression toward or attacks on children and adults; attacks on pet dogs and cats; attacks on hobby animals, such as poultry, sheep, and goats; and damage to drip irrigation systems, garden crops, and to other resources. In addition to providing information, the website allows individuals to upload photos or video clips of urban and suburban coyotes, and to submit firsthand reports …


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

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

Wildlife Damage Management Conference Proceedings

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 (x) …


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

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

Wildlife Damage Management Conference Proceedings

Between 1968 and 1978, aerial photography was used to monitor distribution of blacktailed 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 …


In-Burrow Application Of Rozol To Manage Black-Tailed Prairie Dogs, Charles D. Lee, Philip Gibson, Jeff Wilson Jan 2005

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

Wildlife Damage Management Conference Proceedings

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 …


The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter Oct 2000

The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter

Wildlife Damage Management Conference Proceedings

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 …


Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field Oct 2000

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 …
