“…There have been a number of techniques explored for luring possums to a bait station, including smell, taste, sound, and visual stimuli (Ogilvie and Sakata 2006, Warburton and Yockney 2009, Thomas and Maddigan 2004. Possums seem to be attracted to light; studies have shown that fluorescent lures beside wax bait interference devices will give higher number of bites than those without a fluorescent lure .…”

The use of infrared-flash camera traps has increased dramatically over the past ten years particularly for capturerecapture population studies of distinctly-marked species. However, to use capture-recapture with the more inconspicuous species, high-quality colour imaging (and therefore white flash) is required. A potential problem with white flash is that it may negatively affect behaviour, in this case at bait stations, therefore causing results that do not truly represent possum activity. Possums were used in this study to compare two different types of camera trap: infrared and white flash. Camera traps were placed to take images of possums visiting bait stations, and the number of possum visits was used to determine if white-flash cameras gave different results to infrared-flash cameras. The white-flash cameras had slightly higher possum visits than infrared-flash cameras but the difference was not significant (P=0.437). Over time, the number of possum events (P=0.62) and the amount of time possums spent at the stations did not differ significantly (P=0.81). There was also no difference in the amount of bait taken by possums at white flash compared to infrared stations (P=0.61). Results show possums are not likely to be affected by white-flash cameras compared to infrared-flash cameras. This study therefore showed that there is unlikely to be any behavioural disadvantage in using white flash over infrared, allowing white-flash cameras to be investigated for their potential in identifying individual possums, and as a monitoring tool in control operations.

“…Visual lures have been used to attract brushtail possums ( Trichosurus vulpecula ) in New Zealand where they are a pest species, for management practices. These visual attractants were more effective when they included a luminescent strip as opposed to plain or UV reflective strips (Short, Turner & Risbey, ; Ogilvie et al ., ). Decoys are widely used as attractants for hunting, strongly suggesting wider applicability in conservation efforts for any colonial or aggregating species.…”

Sensory‐based conservation of seabirds: a review of management strategies and animal behaviours that facilitate success

Sensory-based conservation harnesses species' natural communication and signalling behaviours to mitigate threats to wild populations. To evaluate this emerging field, we assess how sensory-based manipulations, sensory mode, and target taxa affect success. To facilitate broader, cross-species application of successful techniques, we test which behavioural and life-history traits correlate with positive conservation outcomes. We focus on seabirds, one of the world's most rapidly declining groups, whose philopatry, activity patterns, foraging, mate choice, and parental care behaviours all involve reliance on, and therefore strong selection for, sophisticated sensory physiology and accurate assessment of intra- and inter-species signals and cues in several sensory modes. We review the use of auditory, olfactory, and visual methods, especially for attracting seabirds to newly restored habitat or deterring birds from fishing boats and equipment. We found that more sensory-based conservation has been attempted with Procellariiformes (tube-nosed seabirds) and Charadriiformes (e.g. terns and gulls) than other orders, and that successful outcomes are more likely for Procellariiformes. Evolutionary and behavioural traits are likely to facilitate sensory-based techniques, such as social attraction to suitable habitat, across seabird species. More broadly, successful application of sensory-based conservation to other at-risk animal groups is likely to be associated with these behavioural and life-history traits: coloniality, philopatry, nocturnal, migratory, long-distance foraging, parental care, and pair bonds/monogamy.

“…Research on possums has considered biological controls (Cross et al, 2011) and both visual (Ogilvie et al, 2006) and auditory lures (Kavermann et al, 2012). Live rats as intraspecies lures have been investigated as have interspecies olfactory attractants such as insect pheromones (Gould et al, 2007).…”

The development of semiochemical lures for rats Rattus spp. and the Australian brushtail possum Trichosurus vulpecula

<p>Control and monitoring methodologies for vertebrate population management most commonly utilise food-based lures like peanut butter, meat and aromatic pastes, like cinnamon. However, food-based lures are perishable and require frequent replenishment, factors that decrease control operation efficacy and increase costs. The limitations of food-based lures have led researchers to consider new approaches for three of New Zealand’s most damaging pest mammals, the Norway rat Rattus norvegicus, the ship rat R. rattus and the Australian brushtail possum Trichosurus vulpecula. Semiochemical lures, commonly used for invertebrate pest management, might address the limitations of food-based lures and provide benefits such as temporally consistent odour properties, ease of handling, long-life and behavioural-specific responses. However, their identification and use for vertebrate population management remains an underexploited opportunity. This study aimed to identify semiochemicals in foods that may act as effective lures for wild free-ranging rats and possums.</p>
