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

has main function to covering Sumatran tiger. Habitat disturbances of
Blangraweu forest are illegal logging, forest cutting, hunting and gold-mine
