Abstract
Six Malayan sun bears were captured and radio-collared from June 1999 to December 2001 in Ulu Segama Forest Reserve,
Sabah, Malaysia Borneo to study home-range characteristics, movement patterns, activity patterns, population density, and bedding
sites. A total of 343 locations were recorded. Home range sizes, calculated by the 95% adaptive kernel method, averaged 14.86.1
(SD) km2. Bears were found in both primary and logged forests. Daily movement distances from these bears averaged 1.450.24
(SD) km, and were affected by food availability, especially availability of figs. Male Malayan sun bears were primarily diurnal, but a
few individuals were active at night for short periods. The majority of the 26 bedding sites consisted of fallen hollow logs. Other
bedding sites included standing trees with cavities, cavities underneath fallen logs or tree roots, and tree branches high above the
ground. Malayan sun bears exist in primary and logged forests. Well-designed logging practices, maintenance of large trees with
cavities, protection of fig trees, and strict control of poaching should be incorporated into forest management practices in logged
forests.
