Vaccination has been the principal weapon against rabies, however...

  10. Hazards to wildlife associated with underground strychnine baiting for pocket gophers

    Conference Proceedings | Contributor(s): Paul L. Hegdal, Thomas A. Gatz

    Under an Environmental Protection Agency (EPA) contract, we evaluated the hazards associated with strychnine baiting for pocket gophers (Geomys bursarius) with the burrow-builder. On the Sherburne National Wildlife Refuge, Minnesota, we treated 662 ha (1638 acres) with 0.5 percent...

  11. Current changes to vertebrate pest management in New Zealand

    Conference Proceedings | Contributor(s): Peter C. Nelson

    Vertebrate pest control in New Zealand is changing as a result of a reduction in state funding. Monetary assistance for control programs is being withdrawn at $0.8 million per year and currently is $5.4 million. This reduction affects several parts of the organization and the Agricultural Pests...

  12. Radio-telemetry and geographical information systems to assess urban deer zoonoses

    Conference Proceedings | Contributor(s): Karmen M. Hollis, Christopher L. Anchor, James E. Chelsvig, Dwayne R. Etter, J. P. Dubey

    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...

  13. Grazing intensity effects on vegetation, livestock and non-game birds in North Dakota mixed- grass prairie

    Conference Proceedings | Contributor(s): Eric D. Salo, Kenneth F. Higgins, Bob D. Patton, Kristel K. Bakker, William T. Barker

    We conducted studies in native prairie mixed-grass pastures in south~central North Dakota (U.S.A.) during 1989- 2003 to determine how different grazing intensities affected structural characteristics of vegetation, livestock production and the occurrence and density of grassland birds....
