Analysis of faecal samples and feeding remains showed that the drill maintains a diverse, yet not indiscriminate, omnivorous diet throughout the year consisting primarily of fruits and seeds, and to a lesser extent leaves, mushrooms and insects. Drills ingested and dispersed intact seeds from 110 plant types primarily during periods of fruit abundance, while there was a shift towards increased seed predation during the pronounced fruit-scarce dry season. Visual and audio encounters of drill groups during 3,284 km of trail patrols provided information on group structure and primate associations. Mean group size was 43.3 ± 18.4 (range 25-77) and groups with both one and multiple males emitting the adult male specific two-phase-grunt were observed. Solitary males were encountered twice. Drills were in association with at least one additional primate species at some time during most of the encounters, involving all of the diurnal primates in Korup (Cercopithecus mona, C. nictitans, C. erythrotis, C. pogonias, Procolobus pennantii preussi and Cercocebus torquatus) except the chimpanzee (Pan troglodytes). The total drill population was conservatively estimated at 950-1450 within Korup National Park and 2,500-3,000 in the entire Korup region, which makes the region a stronghold for the species’ survival. However, drill subpopulations are becoming increasingly isolated within the ever more fragmented landscape and are under hunting pressure everywhere. Eight core areas were identified across the region as priorities for protection. Interviews with local communities offered insight on the destructive practice of hunting with dogs as well as the socioeconomic role of dogs – information needed for effectively managing this major threat to drill survival. The drill was also found to suffer from a limited local recognition of its current status and legal protection, which is unfavourable for conservation. As a result of the project’s findings, a list of drill-focused conservation recommendations was developed and submitted to government agencies and non-government organizations active in wildlife management and conservation in the region. 34
Conducting hunter interviews (Fabe village, May 2006) Population density surveys and taxonomic assessment of the Western tarsier (Tarsius bancanus borneanus) and Bornean slow loris (Nycticebus menagensis) in the Lower Kinabatangan Floodplain, Sabah, Malaysia RACHEL A. MUNDS Awarded a PSGB Conservation Grant in August 2008 The Bornean slow loris (Nycticebus menagensis) and tarsier (Tarsius bancanus borneanus) are the only nocturnal primates on Borneo. Their current classification as Vulnerable (VU) by IUCN is based only on habitat loss. No recent systematic surveys have been done to determine if they are truly VU. Found only on Borneo and a few surrounding islands, these primates are threatened not only by habitat loss but also by the pet, medicinal and food markets. The aim of this research was to provide a current assessment of the estimated abundance of these primates in a protected degraded floodplain in east Sabah, Malaysia Borneo. The research took place in the Danau Girang Field Centre (DGFC) (5°24' 48"N, 118°02' 16"E, elevation 15 m asl), a cooperative research facility between Cardiff University and the Sabah Wildlife Department. It is a 123- ha flat forest located in the centre of the Lower Kinabatangan Wildlife 35
