Full text linkGiven the widespread loss of old-growth forests throughout the
tropics, it is likely that secondary forests will be a crucial factor in the preservation of biodiversity. An increase in secondary forests has been observed in the tropics where it is believed to cover approximately 50% of the remaining tropical rainforests
INTRODUCTION
Full text linkUlu Baleh, located in the interior of Sarawak, Malaysian Borneo, and situated within the Rajang drainage area, is characterised by numerous small streams and larger tributaries. The area can be accessed traditionally only by long and tiring journeys upriver, and more recently, by land. While biodiversity declines are expected in logged
tropical forests, those that are selectively logged appear to sustain significant biodiversity, especially the older regrowth forests. Ulu Baleh is, in fact, one of few areas in the Kapit region that can boast of old secondary as well as pristine rainforests. Vegetation surveys in the Baleh area have identified populations of hardwood trees (Eusideroxylon zwageri and Eusideroxylon melangangai), ferns (Dicranopteris sp.), nutrushes (Scleria purpurascens), fig trees (Ficus
sp.) and blumes (Fragraea crassipes)
PREFACE
Full text linkSarawak is located in one of the world’s mega diversity regions, and boasts an array of Bornean endemic species, from plants to large mammals, some of which are only found in the State. Some of these species are considered the world’s rarest and most threatened, being distributed in the remotest of habitats

WILDLIFE DEPENDENCY
Full text linkWildlife is exploited for a variety of reasons, for instance, economic development, pest control, subsistence and other traditional needs.
These usages have often impacted the concerned species, resulting in reduced densities, slow reproduction rates and even extinction. Moreover, increase in human populations, improved hunting techniques and gear, ease of accessibility via road networks and modern transportation, and increased
economic benefits have led to increased hunting pressure in many parts of the world

Bats
Full text linkThe forests of Santubong National Park include mangroves, mixed-dipterocarp, heath (Kerangas), and hill forests. This complex environment supports a rich bat diversity, as also observed at the nearby Bako National Park and Tanjung Datu National Park. Observing this diversity is sometimes not an easy affair, as the upland areas are challenging for the deployment of traps. The biodiversity enumerated in this chapter is based on trapping effort that focused on the lower parts of the Park, along established trails
Lands Snail
Full text linkGastropods show high diversifi cation of shell shapes and sculptures. In the tropics, gastropods could be encountered in a variety of habitats. Taxonomically, gastropods are classifi ed in the phylum Mollusca, and have been estimated to contribute approximately 80% of the total species
richness. In general, terrestrial gastropods come in three forms: (1) shelled snails, the constructed shell is used to accommodate the soft body; (2) reduced shell, known as semi-slugs, with visible external shell but not large enough for
the soft body to fi t in, or with internal minute shell which is not visible to the naked eye, and (3) true slugs, or those that have no shells
