Sumatran Tiger Population Boosted by Rare Birth in Indonesia

Jakarta — Taman Safari Indonesia (TSI) II Prigen has announced the birth of four Sumatran tiger cubs (Panthera tigris sumatrae), marking a rare and significant milestone in the conservation of the critically endangered species.

The cubs were born on March 23, 2026, to a breeding pair named Praja and Dini, according to TSI’s Vice President of Life Sciences, veterinarian Bongot Huaso Mulia. The litter consists of three males and one female.

“This is a special achievement, as it marks the second successful birth for Dini, who previously gave birth to two cubs, Isyana and Aura, on May 4, 2021,” Bongot said in Pasuruan, East Java, on Thursday.

Breeding Sumatran tigers in captivity remains a complex challenge. The species is known for its high selectivity in mating, and the process often carries risks, including injury, stress, or even death during pairing. Ensuring the survival of newborn cubs through to adulthood also requires intensive care and monitoring.

The birth of four cubs in a single litter is considered above average, as Sumatran tigers typically give birth to only two cubs at a time.

Bongot emphasized that the success of the breeding program was supported by several key factors, including the keepers’ ability to identify the female’s fertile period, careful monitoring of mating behavior, veterinary support, and the preparation of a safe and comfortable birthing enclosure.

“We continue to strengthen our breeding program and aim for at least one successful birth each year to support the conservation of this endangered species,” he said.

He added that the 24 Sumatran tigers currently housed at Taman Safari Indonesia are not part of any commercial initiative, but are maintained solely for conservation purposes, with the goal of increasing the species’ population.
