The importance of free longitudinal passage of river fauna is stressed.

This book contains research findings from three major study areas, natural sciences, social sciences, and public policy and management. The focus area extends over geographical zones ranging from mountainous area of Mount Gagau in the Taman Negara National Park, down to the coastal islands of Bidong, Redang and Perhentian on the eastern coast of Peninsular Malaysia. Chapters on natural sciences examine the physicochemical characteristics of water, physiological and ecological constraints to geological and climatological aspects. The social science and management chapters observe the rich ethno-heritage of local communities and how they interact and develop as a culture, and public policy for sustainable management. Viewpoints from political science, history, sociology, economics, anthropology and management science are also taken into account. This book is intended for researchers and graduate students to create an understanding of the rich heritage, while policy makers plan for future generations. Readers will benefit from this book by studying the gaps in the current knowledge and move to develop further research to understand the unexplored forest canopies and the dynamics of the changing Greater Kenyir landscapes.
