Hollow-dependent endotherms can experience hyperthermia and dehydration when occupying poorly insulated nest boxes during extreme heat. In this study, we compared cavity microclimates inside different artificial hollows during extremely hot summer weather, and showed that chainsaw hollows carved into live trees provide a much more stable and buffered microclimate than do log hollows and nest boxes. We recommend that managers consider incorporating chainsaw hollows into wildlife conservation programs in regions that experience extremely hot weather events. Photograph by Stephen Griffiths.

Conservation Detection Dogs (CDDs) are a highly effective means of collecting data on elusive and low-density plant and animal species, yet they can be inaccessible for many conservation organisations. A model in which skilled and committed volunteers participate in CDD training and deployment may increase CDDs accessibility. This study explores the motivations and satisfaction of handlers in a volunteer-based CDD model over 3 years and discusses implications for recruitment and retention to promote long-term cost effectiveness of volunteer-based programs.

A feral cat eradication program is underway on Kangaroo Island, but controlling cats in large stretches of woodland remains a significant challenge. To address this issue, we tested the efficacy of the feral cat bait ‘Curiosity’ in woodland habitats. After baiting, the density of feral cats fell from 1.18 to 0.58 cats km ⁻², and 75% (six of eight) of GPS-collared cats within the zone died. Photograph by Rosemary Hohnen.

Knowledge of the seasonal movements of small insectivorous bats is essential for their conservation. We describe the seasonal cycle of congregation and movement patterns of the southern bent-winged bat, a critically endangered taxon in southeastern Australia. We record previously unknown movements by this taxon, and a more-than doubling of the overnight flight distance currently used to define management buffer zones. These findings have important implications for managing emerging risks, such as mortalities at windfarms and potential spread of exotic disease. Photograph by Emmi van Harten.

The sambar deer has been identified as a major threat to high-elevation peatlands in south-eastern Australia. Our 4-year camera study revealed that sambar deer utilised peatlands during October–June. Sambar deer activity was crepuscular and was greatest in dense woody vegetation cover close to roads. Ground-based shooting reduced sambar deer activity in peatlands. Photograph by camera trap.
