  • 1. WILDLIFE DISEASE - DEER LESLIE MCFARLANE WILDLIFE DISEASE PROGRAM COORDINATOR Deer with salmonella infection from Tooele County
  • 2. STATEWIDE MANAGEMENT PLAN FOR MULE DEER: Strategy d Investigate and manage disease outbreaks that threaten mule deer populations. Adopt a specific management plan for chronic wasting disease. deer with conjunctivitis (pinkeye) infection Morgan County
  • 3. DISEASES IN WILDLIFE AFFECT POPULATION GROWTH and RECRUITMENT HUMAN HEALTH DOMESTIC LIVESTOCK CONCERNS DIFFICULT TO ERADICATE ONCE ESTABLISHED deer with mange in San Juan County
  • 4. DISEASE MANAGEMENT No intervention Intervention to prevent disease occurrence Reduce the frequency or impact of the disease Complete eradication of the disease
  • 5. CHRONIC WASTING DISEASE (CWD) Cervids Prion disease – not bacteria or virus BSE (mad cow disease), Scrapie, CJD Always fatal Diagnosed by examination of lymph or brain tissue Not known to affect to domestic livestock or humans CWD Positive buck killed by a mountain lion on the La Sal Mountains
  • 6. CWD - TRANSMISSION behavior, saliva, feces, carcasses contaminated sources in environment infective for years 12-24 months in deer 24-36 months in elk
  • 7. CWD – CLINICAL SIGNS
  • 8. CWD - NATIONWIDE Found in free- ranging cervids in 13 states
  • 9. CWD UTAH HISTORY  First tested in 1998  First positive in 2002 near Vernal  Early 2003 on La Sals  Late 2003 near Ftn. Green  First elk 2009  Currently 52 positives
  • 10. CWD SURVEILLANCE Positive WMU every year Rotational basis Hunter-harvest Targeted samples Vehicle kill samples Over 17,000 samples Sampled all WMU’s with in the state at least once
  • 11. CWD  Prevalence in breeding age males (4-6 years of age) is 2-4 x’s higher than in females or young age males  Relationships between density and prevalence (transmission on winter range – spread through migration)  Decreased life expectancy by 2 years  Long-term population effects – decline CWD positive buck from the La Sal Mtns.
  • 12. CWD MANAGEMENT Culling Prohibit feeding Prohibit carcasses Lower population density
  • 13. Why is disease management important for deer populations? Colorado research has shown in two North-central units where trends in adult male mule deer have been monitored since 1996 that CWD prevalence has increased steadily during the last 7 years. Population management Herd health Economic importance –  food supply  Hunter participation Recreation – opportunity Treatment
  • 14. THE END……..
