Tesso Nilo Mourns Death of Conservation Elephant Indro

RRI.CO.ID, Pelalawan - The Tesso Nilo National Park (TNTN) bureau is mourning the loss of one of its most reliable and iconic conservation assets. Indro, a veteran elephant ranger stationed at the Elephant Flying Squad Camp within the Section I National Park Management area of Lubuk Kembang Bunga, Pelalawan Regency, Riau, was pronounced dead early Monday morning, June 29, 2026, after a critical medical intervention failed to stabilize him.

The 45-year-old gentle giant was a cornerstone of local conservation efforts, specialized in mitigating human-wildlife conflicts and safely herding wild elephant clusters away from vulnerable agricultural villages.

According to an official statement released by Head of the Sub-department of Administration at the Tesso Nilo National Park Bureau, Dian Indriati, Indro’s physiological condition collapsed rapidly around 3.30 a.m. local time on Monday, June 29, 2026.

"The veterinarian and the mahout team immediately performed an emergency respiratory examination and performed cardiopulmonary resuscitation (CPR) for several minutes. However, Indro did not respond and was declared dead," Dian confirmed in her official briefing, as quoted by Infopublik.id.

Medical records suggest that Indro's fatal decline was triggered by severe health complications following an extended, highly intense musth cycle, a periodic condition in male elephants characterized by a massive surge in reproductive hormones and heightened, unpredictable aggression.

Veterinary teams first logged a noticeable drop in Indro's appetite between late April and early May 2026. By early June, his behavioral patterns became increasingly erratic and hyper-aggressive, making it unsafe for his mahouts (elephant handlers) to approach him.

To guarantee worker safety while ensuring the elephant's welfare, handlers built remote feeding protocols, supplying banana stems, coconut fronds, elephant grass, and fresh water from a secure distance.

On June 24, 2026, as the musth period extended far beyond normal parameters, rangers deployed additional securing chains to manage his movements. Following a subsequent veterinary sedation procedure to facilitate a medical checkup, Indro’s vital signs deteriorated, marked by a near-complete refusal to eat or drink.

In a frantic 24-hour bid to save his life, a specialized wildlife medical team initiated intensive emergency therapies. Veterinarians administered large-volume intravenous fluid replacements, energy supplements, manual fecal evacuations, and targeted fluid therapies.

Indro initially showed encouraging signs of recovery, he began drinking voluntarily, showed interest in soft forage, and maintained a stable core body temperature.

Tragically, the recovery was short-lived. Rangers found Indro collapsed in his enclosure in the pre-dawn hours of Monday. Emergency CPR and respiratory support were immediately administered by on-call veterinarians, but the veteran elephant ultimately succumbed to internal organ failure.

Indro’s passing is regarded as a massive blow to the Sumatra conservation network. For over a decade, his discipline, strength, and unique training within the elite Elephant Flying Squad served as a critical defensive shield, saving both human lives and wild elephant herds from lethal encounters across the rapidly shrinking forests of Riau. ***
