forests. With the rapid reduction of sun bear habitat, the
conservation of the Malayan sun bear is challenging.
Wise conservation planning requires information on the
biological needs of this species. We present information
on home range size, movement and activity patterns,
and bedding sites of Malayan sun bears in Ulu Segama
Forest Reserve, Sabah. These data were collected during
a 3-year field study designed to gather biological and
ecological information about the Malayan sun bear in
the lowland tropical forests of Borneo.
