I recently provided advice on the precision to be expected from a trial of a new method of luring mammalian pests (feral cats, possums, and stoats, for example), to be carried out in Hikaroroa Reserve, near Karitane, NZ. This work was carried out for Thomas Hayward of Mammalian Corrections Unit (Dunedin, NZ), and was valuable in assessing the number of traps, and number of days trapping, that would be required to obtain a precise estimate of the increase in the kill-rate from using the new method.
