The Borneo Highlands are both mysterious and magical. It is a living museum of remarkable plants and animals. The forests harbour trees ranging from the stunted to the towering, many with exquisite flowers, ferns, herbaceous flora, as well as uncountable endemic insects and vertebrate animals. There is a lack of information on the biodiversity of Gunung Penrissen, but a growing demand for such information from visitors, scientsit, sociologists and conservation managers. This book draws material from new research and a review of literature. The many images provide breathtaking views of the site for tourist as well as offer important geological and species-specific information for researchers and the general public.
