Deer Guards And Bump Gates For Excluding White-Tailed Deer From Fenced Resources, Kurt C. Vercauteren, Nathan W. Seward, Michael J. Lavelle, Justin W. Fischer, Gregory E. Phillips Jan 2009

Deer Guards And Bump Gates For Excluding White-Tailed Deer From Fenced Resources, Kurt C. Vercauteren, Nathan W. Seward, Michael J. Lavelle, Justin W. Fischer, Gregory E. Phillips

Human–Wildlife Interactions

White-tailed deer (Odocoileus virginianus) causing damage is a reoccurring theme in the realm of wildlife damage management, especially regarding human safety, disease transmission, and agricultural losses. Fences often are the only reliable long-term nonlethal means of controlling deer damage. The efficacy of fences, however, relies on their weakest link: human-operated gates. Although not overly time-consuming, the act of closing a gate appears to be a burden to individuals, resulting in open-access to an otherwise protected resource. We examined the efficacy of 2 alternatives to traditional gates to evaluate their potential to be used for excluding or containing deer. …


Molt Migration By Giant Canada Geese In Eastern South Dakota, Charles D. Dieter, Bobby J. Anderson Jan 2009

Molt Migration By Giant Canada Geese In Eastern South Dakota, Charles D. Dieter, Bobby J. Anderson

Human–Wildlife Interactions

We captured giant Canada geese (Branta canadensis maxima) in 7 counties in eastern South Dakota during the summer molting period, 2000–2003. We attached very high frequency (VHF) transmitters to 150 adult female geese with brood patches, and leg bands to 3,839 geese. We documented molt migrations using VHF telemetry and indirect band recovery at locations north of South Dakota. Telemetry of radio-collared female geese during the breeding season indicated that 56% of nonbreeders, 81% of unsuccessful breeders, and 19% of successful female breeders embarked on a molt migration. Five of 34 geese that underwent molt migrations moved to northeast South …


White-Tailed Deer Attacking Humans During The Fawning Season: A Unique Human-Wildlife Conflict On A University Campus, Ryan D. Hubbard, Clayton K. Nielsen Jan 2009

White-Tailed Deer Attacking Humans During The Fawning Season: A Unique Human-Wildlife Conflict On A University Campus, Ryan D. Hubbard, Clayton K. Nielsen

Human–Wildlife Interactions

Human–wildlife conflicts associated with suburban white-tailed deer (Odocoileus virginianus) populations have increased in the last 20 years. Primary threats to human health and safety associated with overabundant deer populations include deer–vehicle collisions, attacks on humans, disease, and damage to native and ornamental vegetation. During the fawning seasons (May–June) of 2005 and 2006, 13 confirmed incidences of white-tailed deer attacking humans occurred on the campus of Southern Illinois University–Carbondale. To our knowledge, no report exists that documents free-ranging does attacking humans during the fawning season. The attacks occurred at multiple locations on campus, with injuries to humans, including minor …

Developing Bird-Strike Risk Assessment Models For Open-Water Restorations, Justin D. Hart, Alison Colyer, John R. Allan Jan 2009

Developing Bird-Strike Risk Assessment Models For Open-Water Restorations, Justin D. Hart, Alison Colyer, John R. Allan

Human–Wildlife Interactions

Mineral extraction sites that are restored to open water can increase bird-strike risk if they are planned near airports. This can generate conflict between the minerals industry and safeguarding authorities. To help resolve this potential conflict, it would be useful to predict how new restorations affect local water-bird populations so that mineral deposits can be exploited and restored in safeguarded zones without compromising flight safety. Bird abundances and movements at new restorations can be estimated with statistical models that use the environmental characteristics of restoration schemes as predictor variables. These models can improve guidance in safeguarding, provided that they comprise …


Role Of Near-Miss Bird Strikes In Assessing Hazards, Matt W. Klope, Robert C. Beason, Timothy J. Nohara, Michael J. Beiger Jan 2009

Role Of Near-Miss Bird Strikes In Assessing Hazards, Matt W. Klope, Robert C. Beason, Timothy J. Nohara, Michael J. Beiger

Human–Wildlife Interactions

Management of problem wildlife within the airfield environment is a difficult job. Today’s Bird–Animal Aircraft Strike Hazard (BASH) program managers require as much information as possible to accomplish their tasks. Bird censuses and actual bird-strike events in and around the air operations area are used to make airfield management decisions and to assess the risk of bird hazards to aircraft. Both types of information are sampled rather sparsely. Avian radar is now being used as a new tool to provide continuous sampling of bird activity that significantly supplements visual censuses. The measure of risk used today is commonly expressed as …


Coexisting With Cougars: Public Perceptions, Attitudes, And Awareness Of Cougars On The Urban-Rural Fringe Of Calgary, Alberta, Canada, Clarisse Thornton, Michael S. Quinn Jan 2009

Coexisting With Cougars: Public Perceptions, Attitudes, And Awareness Of Cougars On The Urban-Rural Fringe Of Calgary, Alberta, Canada, Clarisse Thornton, Michael S. Quinn

Human–Wildlife Interactions

Interactions between humans and cougars (Puma concolor) have been steadily increasing over the past 20 years largely due to human encroachment into cougar habitat and an increase in the human population. We determined the attitudes, knowledge, and perceptions toward cougars by residents in the urban-rural fringe of Calgary, Alberta, Canada, an area populated by both cougars and humans. We sent a survey to a stratified, random sample of 1,508 residents. Survey analysis included a potential for conflict index (PCI) to help provide quantitative direction for future cougar management. We analyzed and tested for differences among 7 variables: livestock …
