Sumatran Tigers Thrive in Protected Forests

Quick Smiles:

• Camera surveys revealed healthier Sumatran tiger populations than ever recorded outside national parks.
• Researchers identified 27 tigers, including several cubs, in Aceh’s Leuser ecosystem.
• Local rangers and community collaboration proved essential to tiger conservation success.

On Indonesia’s island of Sumatra, the critically endangered Sumatran tiger finds hope in healthy, well-protected forests.

Recent infrared camera surveys captured nearly triple the number of tiger sightings compared to previous efforts, thanks to collaboration between scientists and local rangers in Aceh province.

“We documented a robust tiger population, apparently among the healthiest on the island,” said Dr. Joe Figel, a conservation biologist working with Indonesian wildlife and forestry agencies.

The Leuser ecosystem, three times the size of Yellowstone and widely patrolled by rangers, provides an ideal sanctuary for these majestic cats.

Researchers identified 27 individual tigers—14 females, 12 males, and one unsexed—in 282 clear camera-trap images, signaling healthy habitats and high prey density.

The study recorded three sets of cubs during a six-month period.

Images tracked two tiger brothers from cubhood to adulthood.

This population’s steady numbers are a testament to the combined support of government agencies and community partners.

High female tiger densities suggest secure social systems and the possibility for multiple litters in the coming decade.

The findings also offer valuable data to improve future tiger conservation and monitoring strategies.

“Thanks to the work, activities, and support of government agencies, local Acehnese and Gayo communities, donors, and other researchers, Leuser has maintained important patches of lowland and hill forests where, in Sumatra, tiger prey densities reach their highest levels,” concluded Figel.

Even in forests outside the national park system, dedicated protection efforts have made a lasting difference.

With collaborative care and ongoing vigilance, the forests of Sumatra remain a beacon of hope for these incredible tigers.
