“Some ferrets and feral cats disperse from their home ranges after a successful rabbit poisoning operation; some succumb to secondary poisoning after scavenging poisoned rabbits; some survive but produce fewer young; and some take more native prey. |

Feral ferrets (Mustela furo) as hosts and sentinels of tuberculosis in New Zealand |
“The few data available on dispersal of older ferrets suggested that although some older ferrets may move sufficient distances to take them out of a VRA, this probably only occurs when rabbit populations are drastically reduced” |

Ferrets can also be controlled through secondary poisoning, particularly of rabbit populations, although kill rate is highly variable depending on the toxin used.” |

Environmental Risk Management Authority Reassessment of 1080 |
“7-11%..of ferrets on one site and 8-15%..of ferrets at the other site apparently died of secondary 1080 poisoning [after aerial 1080 poisoning]..while we have evidence that secondary poisoning of cats does occur we monitored insufficient numbers..to reliably estimate mortality rates” (Heyward & Norbury, 1999) |

Environmental Risk Management Authority Reassessment of 1080 |
“The main disadvantages of 1080 for feral pig control is that feral pigs require large doses of 1080 to cause death relative to the smaller doses required for death in many non-target species.” |

“During trials with penned feral pigs, 1080 has caused vomiting which may be relatively prolonged and frequent (O’Brien et al. 1987; O’Brien 1988). In addition, some feral pigs undergo convulsions (O’Brien 1988; Buddle 2000) and can sometimes temporarily recover (possibly with injuries), before again convulsing (Cowled 2004, unpublished data).” |

“In some pig habitat areas aerially applied 1080 baits are used to control possums as part of TB vector control operations. This has the effect of reducing pig hunting activity because of the high risk of secondary 1080 poisoning to hunting dogs. Decreased hunting pressure may see pig populations increase and cause significant agricultural damage, so other cost effective control methods are needed.” |
