Using Non-Invasive Techniques to Study Tree Kangaroos

Document Type


Date of Original Version



The last decade saw an increasing demand for the development of non-invasive methods to study animals. Such methods allow low-disturbance and more realistic assessments of species’ distribution, habitat use, activity times, behaviors and responses to landscape and global changes. They can also engage the public, allowing for involvement that results in obtaining larger sample sizes in cost-effective ways. Thus, non-invasive methods can considerably contribute to the conservation of a species. For tree kangaroos, which spend most of their time in dense canopies of rainforests and are difficult to detect, the development, testing, and application of various non-invasive methods became more popular over the last years. They include genetic methods, the use of signs left by tree kangaroos (such as feces and scratch marks), the application of remote cameras and facial recognition techniques. This chapter will summarize and evaluate the current state of non-invasive methods that have been applied to and developed for the study and conservation of tree kangaroos to provide directions for future research in this field.
