Tragedy in the Rubber Concession: The Lingering Crisis and Ecological Collapse Facing Sumatra’s Elephants in the Bukit Tigapuluh Landscape

JAMBI — In the remote rubber plantations of Tebo Regency, Jambi, a grim discovery has once again highlighted the perilous state of Sumatra’s vanishing megafauna. A roughly one-year-old Sumatran elephant (Elephas maximus sumatranus) was found dead inside a deep trench located just three kilometers from the Business Unit 4 Mandelang camp in Muara Sekalo Village, Sumatran territory.

Trapped and unable to climb out, the baby elephant died of dehydration. Its tragic demise—reported a week after the fact on August 24, 2026—occurred deep within the industrial rubber concession of PT Lestari Asri Jaya (LAJ). The company is a subsidiary of Royal Lestari Utama (RLU), which itself operates under the umbrella of the French tire manufacturing giant, the Michelin Group.

The incident has triggered a high-level investigation by forest law enforcement authorities, serving as the latest entry in a relentless catalog of recurring elephant mortalities across the fragile Bukit Tigapuluh ecosystem. Beyond a localized wildlife accident, conservationists and regulators argue that the calf’s death is a glaring symptom of a much deeper, systemic ecological breakdown driven by corporate concession mismanagement, rampant deforestation, surging human-wildlife conflict, and catastrophic seasonal wildfires.

Main Facts: A Defenseless Calf Lost in Corporate Lands

The immediate facts surrounding the case paint a picture of systemic vulnerability. The calf, part of a severely pressured local population, perished in a hazard situated squarely inside a commercial rubber estate.

Following the belated report, the Directorate General of Forest Law Enforcement (Gakkum Kehutanan) under the Ministry of Forestry launched an immediate inquiry. Investigators inspected the scene and recorded testimonies from a broad spectrum of stakeholders:

• The Conservation Head and the Head Plantation Foreman of PT LAJ.
• Four technical staff members from the Frankfurt Zoological Society (FZS).
• A veterinary medical doctor from the Jambi Natural Resources Conservation Center (BKSDA).
• Field personnel responsible for tracking the herds via GPS collar technology.

A veterinary necropsy confirmed that the juvenile elephant suffered extreme dehydration after falling into the trench. Subsequent laboratory testing on biological samples ruled out poisoning, keeping the investigative focus squarely on corporate liability, environmental negligence, and the failure to secure hazardous terrain within active land-use concessions.

Chronology of Habitat Fragmentation and Escalating Threats

To understand how a young elephant ends up dying alone in an industrial trench, environmental watchdogs point to a decades-long timeline of landscape transformation in southern Bukit Tigapuluh.

• The 1970s–2007: Large-scale commercial logging begins when the French timber firm Industries et Forest Asiatiques (IFA) secures a massive concession spanning over 100,000 hectares. This territory is later acquired by Barito Pacific.
• December 14, 2010: Conservation coalitions—including KKI Warsi, FZS, Eyes on the Forest, and WWF-Indonesia—release a landmark report titled "Last Chance to Save Bukit Tigapuluh." The report documents that the landscape simultaneously supports at least 30 Sumatran tigers, 150 Sumatran elephants, and 130 Sumatran orangutans.
• 2010: PT LAJ secures an industrial timber plantation (HTI) permit covering 61,495 hectares directly south of the Bukit Tigapuluh National Park (TNBT).
• 2018: Under mounting pressure, PT LAJ sets aside 9,700 hectares as a Wildlife Conservation Area (WCA) intended to safeguard critical habitat. However, continuous encroachment, illegal land clearing, and village expansions quickly chip away at the space. By the mid-2020s, satellite and field monitoring reveal that only about 2,800 hectares of actual forest remain within the designated conservation zone.
• May 2024: A female elephant dies from an electric snare trap inside a smallholder oil palm plot located within the WCA managed by PT LAJ in Bruit Pamuatan Village.
• 2025–2026: Independent monitoring groups, such as Yogyakarta-based Geopix, document an explosive expansion of lethal electric wire fences inside the LAJ concession. What began as a 70-kilometer network of illegal perimeter shocks balloons to an estimated 100 kilometers by 2026, alongside the establishment of hundreds of unauthorized residential structures within the WCA.

Supporting Data: The Smoke, the Snares, and the Shrinking Ranges

The tragedy of the dead calf unfolded against the backdrop of an unprecedented ecological catastrophe: massive wildfires sweeping across Jambi’s vital natural landscapes.

According to data compiled by Walhi Jambi, the total area burned across the Bukit Tigapuluh landscape had reached 8,079 hectares by October 18, 2026—dwarf figures previously released by local conservation authorities. Within corporate boundaries, the destruction has been severe:

• PT LAJ Concession: Over 1,573 hectares scorched.
• PT Alam Bukit Tigapuluh (ABT) Restoration Area: At least 2,257 hectares burned.
• PT Restorasi Ekosistem Indonesia (Reki) / Hutan Harapan: More than 2,512 hectares devastated.
• PT Alam Lestari Nusantara (ALN) Rubber Plantation: Roughly 2,500 hectares destroyed.

Nety Riana Sari, Communications and Partnerships Manager at PT ABT, noted that extreme heat driven by El Niño conditions sparked hundreds of hot spots, particularly in Block 2 bordering the national park. While field teams successfully defended the Orangutan Station in Block 1, the thick smoke, loss of vegetative cover, and lack of accessible water severely disrupted daily animal migration routes.

Furthermore, the historical range of Tebo’s elephants has been severed. Historically, elephant herds roamed fluidly across a massive 600,000-hectare tract stretching from Tebo all the way to Serangge in Riau and down to Tanjung Jabung Barat. Today, their survival is restricted to a fractured 82,000-hectare area.

Jambi BKSDA Head Himawan Sasongko highlights a critical behavioral shift in the surviving herds: "Their movement used to be horizontal, from west to east. Now, it has changed to a vertical pattern—from north to south, moving from the LAJ concession into APL [Other Land Use areas] and back again."

Despite these compounding pressures, field data shows that adult females continue to reproduce successfully. However, calves aged around one year—relying entirely on the herd for protection—remain acutely vulnerable to open trenches, electric fences, and toxic hazards. Between 2013 and 2026, monitoring groups have recorded at least 16 elephant mortalities across the Bukit Tigapuluh landscape alone.

Official Responses and Accountability

The rising death toll has drawn sharp rebukes from national forestry authorities, who emphasize that corporate concession holders bear legal and moral responsibility for wildlife safety within their borders.

Hari Novianto, Head of the Sumatra Regional Forest Law Enforcement Center, stated that investigators are meticulously reconstructing how the baby elephant fell into the isolated trench. "We continue to trace additional witnesses and physical evidence. If negligence or regulatory violations are discovered, we will certainly take decisive legal action in accordance with our authority and statutory provisions," Novianto asserted.

Echoing this stance, Dwi Januanto Nugroho, Director General of Forest Law Enforcement at the Ministry of Forestry, underscored that holding a commercial permit is not a unilateral license for extraction.
“Permits do not merely grant the right to conduct business operations; they carry the mandatory obligation to safeguard the forests, habitats, and wildlife living within them,” Nugroho said. He has explicitly directed his teams to audit PT LAJ’s compliance with wildlife and habitat protection mandates.

When Mongabay reached out to Karmila Parakkasi, Chief Sustainability Officer of PT Royal Lestari Utama (RLU), for comments regarding the incident, she requested that questions be submitted via email. As of publication, RLU has provided no official response. Similarly, representatives from PT Reki and PTPN III (overseeing ALN) did not respond to inquiries regarding wildfire devastation within their respective operational zones.

Implications: Ecological Chaos and the Human-Wildlife Interface

Environmental NGOs argue that piecemeal investigations are insufficient to halt a structural collapse. Oscar Anugrah, Executive Director of Walhi Jambi, views the ongoing degradation not merely as a wildlife crisis, but as a symptom of governance failure.

“There is an ongoing scramble for space—between communities and the state, between communities and corporations, and increasingly, between communities and wild animals that have lost their homes,” Anugrah explained. He criticized the government for hastily issuing commercial licenses without adequately factoring in ecological carrying capacities or the needs of migratory species.

Annisa Rahmawati, Senior Wildlife Campaigner at Geopix, drew direct parallels between the deterioration of Bukit Tigapuluh and the collapse of the Tesso Nilo elephant sanctuary in neighboring Riau. She pointed out that despite repeated warnings issued to the Michelin Group regarding massive illegal settlements and more than 100 kilometers of high-voltage electric snares crisscrossing the LAJ concession, enforcement on the ground has been severely lacking.

Conservationists agree that addressing the crisis requires more than reactive conflict management when elephants wander into smallholder gardens or industrial roads. Muhammad Hilal Frikriansyah, Coordinator of the Indonesian Elephant Conservation Forum (FKGI) in Jambi, emphasized that long-term survival depends on restoring ecological corridors along vital waterways like the Sumai, Manggatal, Mandelang, and Pakundangan rivers.

Ultimately, the death of a single calf in a forgotten trench serves as a stark warning. In the contested landscapes of Bukit Tigapuluh and Hutan Harapan, what is truly at stake is not only the survival of the Sumatran elephant, but the state’s capacity to maintain the ecological lifelines that support both human communities and endangered wildlife alike.
