This book describes the natural history of the proboscis monkey found on Malaysian Borneo. Apart from presenting novel research data on the species, it also highlights some of the areas where urgent action is needed to safeguard the long-term survival of proboscis monkeys. It also recommends specific research priorities, including long-term monitoring of population numbers and distribution, and more accurate habitat and land use classifications.
Furthermore, the book attempts to reach out to a wider audience by presenting information that the general public or wildlife enthusiast may be interested in. From an eco-tourism point of view, the importance of the proboscis monkey as a flagship species cannot be underestimated, as it is an easily observable animal with high encounter rates in the wild. Hence, this book also contains useful information on recommended places to visit to observe the proboscis monkey, as well as guidelines for observing them so as to minimise disturbance and to promote sustainable tourism.
