| 2011 Full Book | |
The Sumatran tiger (_Panthera tigris sumatrae_, Pocock 1929) is one of the top predator species with their status as critically endangered species based on IUCN category. Most of Sumatran tiger population monitoring techniques is emphasized on the indirect count. However, the output of population assessing almost appear confussion and more higher biased. And now, monitoring method has developed by camera trap. The objectives of this research is to estimation of Sumatran tiger population using camera trap in Berbak National Park and to identification of Sumatran tiger potential prey. This research was conducted from July until October 2010 in Berbak National Park, Jambi. The equipments were used in this study are DLC Covert II and DeerCam camera trap units, dry cell battery, memory card, film roll, digital camera, and GPS receiver. The research methods is capture recapture method using camera trap which placed at potential locations of tiger presence in study area. Camera was spread at 32 location with the distance each others about 2-2,5 km. Tigers were identified as individual based on their stripes pattern, different characteristic like their morphology and basic body dimension. Estimation of tiger density was analysed by program CAPTURE and effective sampling area wide. A total of collected photo and video is 1031 frame that consist of 262 frame capture the wildlife photographs (25,41%). From 262 wildlife photographs, there is 15 tiger photographs were obtained. A total of identified tiger based on camera trap in study area is seven tigers. The location where recording most of tiger photographs is Parit 14 with seven photographs. Parit 14 is a location with high prey abundant which related to tiger encountered rate by camera trap. The effective sampling area wide is 139,43 km2 with estimating approximately of tiger density based CAPTURE program is 4,39 tiger per 100 km2. The tiger's sex ratio in this study is 4 male and 2 female with the same age class (i.e. adult). There is no a cub was recorded by camera trap. Tiger capture probability in all of occasion is 98% that means to not difficult to find of tiger's signs in study area. The tiger's principal preys specis in study area are breaded pig (_Sus barbatus_), greater mouse deer (_Tragulus napu_), pig tailed macaque (_Macaca nemestrina_), asian tapir (_Tapirus indicus_). A weather factor such as warm and rain is influencing the camera trap performance. Sumatran tiger density is high but the threats of Sumatran tiger and their prey is high too. Needed strongly study about location selection of camera trap to obtain higher Sumatran tiger photographs. |
