Browsing herbivores can also threaten endangered plants and are difficult to manage when herbivores are native and/or not necessarily over abundant. 512 AuZstoraolilaongist volume 43 (4) 2024 Sensory tactics to manage wildlife Current management strategies to curb problem browsing tend to focus on removing...

Faecal pellets collected from each koala were analysed for cuticle fragments to determine the accuracy of this method for estimating the species...

Temperature was generally lower in non-food trees used by koalas in daytime than in the food trees, which were generally used at night. Leaf moisture may influence tree selection during periods...

This is because such areas support dense vegetation cover which both provides shelter from human disturbances such as hunting and abundant young palatable foliage for browsing at accessible height (see...

...). Unsustainable koala densities can occur where habitat is isolated and/or animals are unable or unwilling to disperse (Whisson et al. 2016), often resulting in over browsing and death of food trees, which may subsequently lead to the starvation of individual animals. Increased population densities therefore...
