To manage brushtail possums (Trichosurus vulpecula) accurate estimates of abundance are essential Direct counts are not feasible for large populations and index techniques are normally employed A new index technique for estimating possum abundance is the WaxTagreg; They are potentially more effective than traps because they are small easier to use very lightweight and therefore higher numbers can be set out in the field Whilst a national monitoring protocol for WaxTagreg;s has been developed it is important to determine whether improvements can be made This study investigated firstly whether luminescentcoloured WaxTagreg;s were more attractive than the WaxTagreg; with a flour blaze and secondly whether raising the WaxTagreg;s 700 mm above the ground reduced detectability Possums significantly preferred the flour blaze over luminescence and raising WaxTagreg;s did not significantly reduce detectability Accordingly WaxTagreg;s could be raised up above grounddwelling nontarget species without reducing statistical precision
