Gray Wolf (Canis lupus) Fact Sheet: Managed Care

Managed Care

Lifespan

  • Up to 17 years (Mech and Boitani 2003)

Reproduction

  • Reproduce earlier in managed care settings than in the wild (Medjo and Mech 1976; Seal et al. 1979; Zimen 1976)
    • 10 months of age observed

Association of Zoos and Aquariums (AZA)

  • Mexican wolf (C. l. baileyi)
    • Extinct sub-species in the wild, except for reintroduced populations in Arizona and New Mexico, U.S.A. and in the Sierra Madre Occidental of Mexico (Siminski 2012)
    • 311 individuals (149 males; 162 females) in zoos internationally, as of July 2013 (Siminski 2013)
      • Participants descended from 7 founders (Siminski and Spevak 2013)
      • AZA facilities provide care and breeding expertise to maintain a genetically diverse managed care population; vital for reintroduction efforts (read about the reintroduction program under Population & Conservation Status)
    • Species Survival Plan (SSP) designates target population size of 300 reproductive adults (Siminski and Spevak 2013)
      • Frozen gamete banks established in the 1990s in the U.S. and Mexico; under supervision of U.S. Fish and Wildlife Service and SEMARNAT (in Mexico)
        • Preserve male genes for use in artificial insemination or other assisted reproductive procedures
      • Goals:
        • Maintain genetic diversity (above 90% of that in the founding population)
        • Identify individuals suitable for release programs
  • Canid care manual; details protocols for habitat design, transport, medical care and nutrition, maintenance of social environment, as well as reproductive and behavior management (AZA Canid TAG 2012)
    • Created to ensure canid physical and mental welfare of wolves at AZA-accredited institutions
