Wildlife Mitigation Strategies

Recently the ZAHP Fusion Center, along with AZA and American Association of Zoo Veterinarians recently had a discussion with USDA Wildlife Services, Animal Care and Veterinary Services to discuss wildlife mitigation strategies.  Epidemiologists and scientists are still determining how the highly pathogenic avian influenza (HPAI) is spreading so rapidly in poultry farms in the upper Midwest.  One thing is certain:  Dabbling ducks (mallards, etc.) are reservoirs for the virus.  In many instances, we cannot make our exhibits, especially ponds, ‘wildlife proof’.

USDA Wildlife Services (WS) has shared with us some strategies, which may help to make our facilities less attractive to wildlife.  You are encouraged to contact your State Department of Natural Resources (or equivalent) and State USDA Wildlife Services program for specific assistance.   Their toll-free number is  (866) 4USDA-WS (866-487-3297), or you can link into your State’s WS program through the APHIS website.

The USDA understands the issues facing zoos and aquariums in trying to protect their collections, while respecting wildlife.  It is likely that we may develop a webinar on this topic in the future, but in the interim we encourage you to look over the included documents outlining some non-lethal methods of addressing free-ranging wildlife.
