The degradation of 1080 in buried Foxoff(R) baits was investigated. Baits w
ere exposed to 5 different treatments: shelf-stored controls, prevailing we
ather, no rainfall, average weekly rainfall and twice average weekly rainfa
ll. Curvilinear regression models were used to model the rates of decay of
1080. These predicted that under normal rainfall conditions, baits would be
come non-lethal to working dogs at 2.2 weeks and foxes at 2.8 weeks. Manage
ment implications of these results are discussed.
