Potensi populasi dan karakteristik habitat harimau Sumatera (Panthera tigris sumatrae, Pocock 1929) di hutan Blangraweu - Ekosistem Ulu Masen, Provinsi Aceh

Abstract

Sumatran tiger’s condition was threatened by forest over function, with the result of decreasing its population. Blangraweu forest area is one of suitable habitat and potential for Sumatran tiger existence. There is no recently data, which can be estimating about population of Sumatran tiger is a problem in tiger sustainability, especially in Aceh. This research was held for six months, started on November 30th 2009 until May 28th 2010 in Blangraweu forest area – Ulu Masen ecosystem, Pidie and Pidie Jaya, Aceh. The purpose is to estimate population density, and to identify habitat component and characteristic of Sumatran tiger in Blangraweu forest. The data was collected by camera trap method and vegetation analysis to find vegetation structure and composition where consist of its habitat. Population Estimation of Sumatran tiger in Blangraweu forest area is 5 – 9 individuals per 211,25 km2 effective sampling area. Density level of Sumatran tiger with 95% deviation standart is about (X  SE) 2 – 4 individuals (2,36 – 4,07  2,43 individuals/100 km2). Sex comparison between male and female positively is 1 : 4, which age structure are 5 adult individuals. Blangraweu forest has two type of habitat, are mountain and sub-mountain forest. Main preys are sambar deer, deer, and bearded pig. Water resources which used by Sumatran tiger source is river during the year with pure water. Crown cover as forest has main function to covering Sumatran tiger. Habitat disturbances of Blangraweu forest are illegal logging, forest cutting, hunting and gold-mine exploration.
