NEED FOR RULE AND BACKGROUND The purpose of this rule is to
reduce hybridization, or cross-breeding, between captive-reared (domestic)
mallards and Florida's wild, native mottled ducks. These year-round resident mallards are not part of Florida's native wildlife, and, like most other exotic species, are causing problems. These released mallards pair with mottled ducks and the two species interbreed, resulting in hybrid offspring. State biologists frequently observe mixed flocks, mixed pairs, and the resulting hybrid offspring. The hybrid offspring are fertile, which further compounds the problem. Every mallard released in Florida can potentially contribute to the hybridization problem. Because of the relatively small size of the Florida mottled duck population, complete hybridization of the population is a serious concern. In fact, biologists list hybridization with feral mallards as the biggest immediate threat to the conservation of Florida's mottled duck. The purpose of
this rule is to (1) specifically prohibit the possession of
mallards other than by those persons appropriately permitted and (2) to require caging
in order to reduce accidental release and interaction of captive mallards
with wild waterfowl. Also, the rule explicitly prohibits the release
of mallards other than by licensed hunting preserves, and for dog and
raptor training and field trials. Information on mallard hybridization with Florida's native mottled duck |
