This paper presents a preliminary analysis of the relative abundance of mammals based on camera-trapping data and track counts at Sg. Relau (Merapoh) Taman Negara Pahang. Abundance is expressed as a Relative Abundance Index (RAICT) based on 'detection' (i.e. 1 photographs of a species/trap-night/trap location) and total trap nights (n 4192) for camera-trapping data. The trackcount data or RAITc . were based on 'counts' (i.e. a 100-m strip of the ground where 1 tracks of species were recorded) on a total of 119 sample strips. The camera trapping yielded a total of 1513 photographs of 43 vertebrate species which translated into 923 detections. The track counts produced a total of 312 counts of 16 species. The most common medium to large ungulate were wild boar Sus serofa (RAICT 2.55 RAITC 0.67) tapir Tapirus indicus (RAlCT 4.22 RAITC 0.35) barking deer Muntiacus muntjac (RAlCT 2.55 RAITC 0.41) and elephant Elephas maximus (RAlCT1.03 RAITC 0.41) in that order. Both sambar deer Cervus unicolor (RAIcT 0.29 RAITC( 0.13) and seladang Bos gaurus (RAICT 0.072 RAITC 0.24) were uncommon. Among carnivores the sun bear Helarctos malayanus (RAICT 1.27 RAITC 0.0067) and leopard Panthera pardus (RAICT2.48 RAITC 0.034) were relatively common. The rarest large terrestrial mammals in the study site were Sumatran rhinoceros Dicerorhinus sumatrensis (RAlCT 0 RAITC 0) serow Capricornis sumatrensis (RAlCT 0.024 RAITC( 0) wild dog Cuon alpinus (RAICT 0.07 RAITC 0.0017) and the tiger Panthera tigris (RAICT0.29 RAITC0). Recommendations in the application of camera trapping and track count to assess large mammal abundance are discussed.

Abstract

This paper presents a preliminary analysis of the relative abundance of mammals based on camera-trapping data and track counts at Sg. Relau (Merapoh) Taman Negara Pahang. Abundance is expressed as a Relative Abundance Index (RAICT) based on 'detection' (i.e. 1 photographs of a species/trap-night/trap location) and total trap nights (n 4192) for camera-trapping data. The trackcount data or RAITc . were based on 'counts' (i.e. a 100-m strip of the ground where 1 tracks of species were recorded) on a total of 119 sample strips. The camera trapping yielded a total of 1513 photographs of 43 vertebrate species which translated into 923 detections. The track counts produced a total of 312 counts of 16 species. The most common medium to large ungulate were wild boar Sus serofa (RAICT 2.55 RAITC 0.67) tapir Tapirus indicus (RAlCT 4.22 RAITC 0.35) barking deer Muntiacus muntjac (RAlCT 2.55 RAITC 0.41) and elephant Elephas maximus (RAlCT1.03 RAITC 0.41) in that order. Both sambar deer Cervus unicolor (RAIcT 0.29 RAITC( 0.13) and seladang Bos gaurus (RAICT 0.072 RAITC 0.24) were uncommon. Among carnivores the sun bear Helarctos malayanus (RAICT 1.27 RAITC 0.0067) and leopard Panthera pardus (RAICT2.48 RAITC 0.034) were relatively common. The rarest large terrestrial mammals in the study site were Sumatran rhinoceros Dicerorhinus sumatrensis (RAlCT 0 RAITC 0) serow Capricornis sumatrensis (RAlCT 0.024 RAITC( 0) wild dog Cuon alpinus (RAICT 0.07 RAITC 0.0017) and the tiger Panthera tigris (RAICT0.29 RAITC0).
