This book and the other books in this series are dedicated to Nguyen My Hanh, a dear friend whose passion, devotion, and love for humanity have inspired every page. Publication of this book would not have been possible without the support of several institutions and individuals. We owe particular thanks to WWF UK for financial support of this book. Special thanks also to Pham Hong Nguyen and Do Huong Giang, whose contributions to the book are highly appreciated, to Wendy Tubman for editing in English, to all the staff involved in the Central Vietnam Tiger Corridor Project at the Forest.
