Kelimpahan Artiodactyla Mangsa Harimau Sumatera Dengan Bantuan Kamera Jebak Di Suaka Margasatwa Bukit Rimbang Bukit Baling
The existence of the Sumatran tiger (Panthera tigris sumatrae) depends ultimately on the abundance of its potential preys in its remaining natural habitats. Yet, little is known about it in almost all areas where the presence of the big cat has been positively confirmed, such as in Bukit Rimbang-Bukit Baling Wildlife Reserve in Riau Province. The objectives of the present study were: (1) to explore the species diversity of tiger’s potential preys in this reserve; and (2) to assess their abundance. We operated 20 pair of camera traps in 20 cells of 2 km x 2 km for a total of 1,712 trap-nights between November 2011 and February 2012. Focusing on artiodactyls, we successfuly obtained 513 independent images containing five species, i.e. bearded pigs (Sus barbatus), barking deer (Muntiacus muntjak), eurasian wilpig (Sus scrofa), sambar deer (Cervus unicolor), and Sumatran serow (Capricornis sumatraensis). Almost all specieses spread in altitude about 100-500 asl. All species mostly active all day long. Based on the Relative Abundance Index (RAI) of the individual species, our results suggest that bearded pig (RAI=20.67) was the most abundant and probably also the most important prey of the critically-endangered tigers inhabiting the reserve.
