Evaluation of Non-toxic Bait Interference for Indexing Brushtail Possum Density
Percentage non-toxic bait interference is currently used by local authorities to monitor brushtail possum control operations but the validity of the method has not been established. Two models have been proposed to estimate an index of possum density (possums per bait) from a log-transformation of percentage bait interference. In two trials, percentage bait interference and the density index de...
متن کاملImproving Aerial Control of Possums by Precision Bait Delivery
Aerial delivery of 1080 (sodium monofluoroacetate) baits is the main technique for reducing populations of New Zealand's foremost vertebrate pest, the Australian brushtail possum, in large areas of inaccesible country. Surveys after pilot-controlled aerial sowing of baits in seven operations in forests showed that inaccurate navigation along the swaths left up to half the target zone untreated....
متن کاملA comparison of wildlife control and cattle vaccination as methods for the control of bovine tuberculosis.
The Australian brushtail possum is the major source of infection for new cases of bovine tuberculosis in cattle in New Zealand. Using hypothetical values for the cost of putative cattle and possum Tb vaccines, the relative efforts required to eradicate Tb in cattle using possum culling, possum vaccination or cattle vaccination are compared. For realistic assumed costs for 1080 poison bait, poss...
متن کاملSecondary and Tertiary Poisoning Risks Associated with Brodifacoum
The field use of brodifacoum baits (Talon® and Pestoff®) to control brushtail possums (Trichosurus vulpecula) has increased in recent years. This has raised concerns of secondary and tertiary poisoning, resulting from the transfer of this toxicant through the food chain. In New Zealand, feral pigs (Sus scrofa) are known to scavenge possum carcasses and may also gain access to bait stations cont...
متن کاملRabbit bait-take from plastic bait stations
Plastic bait stations were trialled to assess their usefulness as a rabbit control tool. Non-toxic cereal baits were applied at two 171 ha Mackenzie Basin sites, at one site in stations and at the other site spread directly on the ground. Bait-take at each site was measured. Rhodamine-dyed baits were also used to determine the proportion of rabbits at each site that took bait. Bait-take, and th...
