Abstract

Penang National Park was surveyed to model nest-site selection of the White-Bellied Sea-Eagle (WBSE) using the
geographic information system of the study site (latitude
5⁰ 28' N
and longitude
100⁰ 10' E
). Using two habitat variables
(topographic and disturbance) nest-site selection analysis was carried out to examine significant differences between the sites
used by the WBSE. A digital elevation model showed that the study area was characterized by high elevation (450⁰
) with pockets
of low elevation at the edges. Higher percentages of elevation clusters were obtained at the southern region of the study area
(mean elevation, 92 m) and it was significantly lower than the mean elevation of the entire park (147). The average slope of the
nest sites (22.5±7.0°) was significantly higher than the general average slope of random points (18.6±9.4°) in the entire park. The
occupation-model gives a parsimonious prediction of the WBSE population in an area for biodiversity conservation.
