Nila Kartika Wati
The fragile equilibrium of Kalimantan’s wetland ecosystems has suffered a devastating blow as the latest wave of forest and land fires (karhutla) claimed the lives of numerous protected proboscis monkeys, locally known as bekantan (Nasalis larvatus). In the remote village of Balimau, located within the Kalumpang district of Hulu Sungai Selatan, the scorched remains of these iconic primates were discovered on September 13, 2026, serving as a harrowing testament to the intensifying conflict between human-induced environmental degradation and the survival of Indonesia’s endemic wildlife.
As the smoke clears, the incident has ignited a fierce debate regarding the efficacy of current conservation policies, the legal status of habitat protection, and the systemic failures that leave nearly two-thirds of the bekantan population vulnerable to the creeping reach of seasonal fires.
A Chronology of the Balimau Incident
The catastrophe in Balimau began as a localized brush fire in a neighboring village, but rapidly escalated due to severe drought conditions and the accumulation of dry rumbia vegetation. According to Alamsyah, the village head of Balimau, the fire crossed the local river channel, propelled by strong winds that carried embers across the landscape.
By the time the flames were contained, the toll on the local fauna was staggering. Community members and local responders discovered 11 bekantan carcasses—ten adults and one infant—trapped in a lethal bottleneck. Experts believe the animals were disoriented and physically blocked from escaping, as the fire advanced from one direction while human activity and emergency responders concentrated on the other, effectively cutting off the primates’ only path to safety.
The BKSDA (Natural Resources Conservation Agency) of South Kalimantan later expanded this assessment, noting that the environmental impact extended beyond the primates. Their surveys identified a total of 12 bekantan impacted by the fire, alongside the deaths of a reticulated python and a king cobra, species that play critical roles in maintaining the health of the wetland ecosystem.
The Logistics of Failure: A Struggle Against Drought
The efforts to mitigate the Balimau fire were hindered by severe infrastructural limitations. As regional water sources dried up under the prolonged dry season, local residents found themselves ill-equipped to combat the rapidly spreading blaze. With only portable pumps available to the village community, the response time was dictated by the arrival of specialized equipment and tankers from outside the district, a delay that ultimately proved fatal for the trapped wildlife.
Alamsyah noted with frustration that the community had petitioned for the formal protection of the Balimau bekantan habitat as early as 2016. Despite years of advocacy and repeated requests for government intervention to secure the area, these pleas remained largely unaddressed. The recent tragedy highlights a recurring pattern in Indonesian conservation: the tendency for authorities to mobilize only after an ecological disaster has already occurred, rather than investing in proactive landscape management.
Mapping the Vulnerability: The "Outside-Zone" Crisis
The crisis in Balimau is not an isolated event. Reports from the neighboring districts of Sungai Rutas Hulu and Sungai Rutas in the Tapin Regency indicate that while no bekantan deaths were immediately confirmed in these areas, the destruction of their primary foraging grounds and canopy corridors is extensive. The loss of vegetation in these regions creates a long-term ripple effect, as the recovery of mangrove and rumbia habitats can take several months to years, forcing displaced primate groups into closer proximity with human settlements and agricultural zones.
The broader data provided by the Regional Disaster Management Agency (BPBD) of South Kalimantan paints a grim picture of the 2026 fire season. Between January and September 15, 2026, the agency documented 3,256 fire incidents, resulting in a staggering 21,696 hectares of land scorched.
The core of the conservation crisis lies in the jurisdictional gap between protected and unprotected lands. According to 2025 data from the BKSDA, the total population of bekantan in South Kalimantan stands at approximately 3,757 individuals, distributed across 11 cities and regencies. Critically, only 1,281 of these animals—roughly 34 percent—reside within designated conservation areas. The remaining 2,476 individuals, representing nearly two-thirds of the population, live on lands that lack formal protected status, placing them outside the direct mandate of national conservation authorities.
Official Responses and the Jurisdictional Quagmire
Agus Ngurah, the head of the BKSDA in South Kalimantan, acknowledged the complexities of protecting wildlife in fragmented landscapes. He emphasized that the agency maintains a robust framework for fire prevention and rescue, including the Wildlife Rescue Unit (WRU) and consistent patrols. However, Ngurah admitted that these mechanisms are structurally tied to existing conservation zones.
"Our capacity for intervention is most effective within the areas under our direct administration," Ngurah explained. "For habitats located outside these formal zones, we are dependent on multi-stakeholder coordination, involving local government bodies and private landholders."
To address this, the BKSDA is advocating for the implementation of an "areal preservasi" (preservation area) scheme. This policy would allow for the expansion of wildlife corridors and protected buffers on land currently outside the formal conservation network, effectively bringing private or community-owned forest patches under a protective legal framework. However, the success of this scheme depends heavily on the willingness of local governments to prioritize ecological preservation over commercial land use.
Expert Perspectives: Beyond Fire Suppression
The academic community has expressed significant concern over the current reactive approach to forest fires. Professor Muhammad Arief Soendjoto, a leading authority on flora and fauna conservation at Lambung Mangkurat University, characterizes the current strategy as fundamentally flawed.
"We are focusing far too much on the fire itself and not enough on the landscape that feeds it," Soendjoto stated. "We have systematically cleared their habitats for timber and agriculture, and then we act surprised when the remaining fragments succumb to fire. Even if these animals survive the flames, the smoke alone creates a respiratory crisis, and the destruction of their canopy leaves them with nowhere to go."
Soendjoto argues that a paradigm shift is required. He advocates for a multi-pronged approach that moves beyond reactive fire suppression to include:
- Community-Based Prevention: Active engagement with religious and community leaders to discourage the use of fire as a tool for land clearing, particularly during the dry season.
- Stringent Law Enforcement: Increasing the penalties and oversight for parties responsible for starting fires, whether through negligence or intent.
- Landscape Connectivity: Prioritizing the creation of corridors that link fragmented habitats, ensuring that wildlife have the mobility to escape localized fires.
The Path Forward
The death of the bekantan in Balimau serves as a clarion call for the provincial and national government to re-evaluate how they manage the intersection of economic development and biodiversity. As the climate becomes increasingly unpredictable, the historical approach—where environmental protection is secondary to industrial expansion—is proving to be an existential threat to the region’s unique primate population.
Without a robust, binding policy that recognizes the necessity of protecting habitats regardless of their administrative classification, the bekantan of South Kalimantan remain caught in a cycle of displacement and tragedy. The challenge for policymakers in the coming months is to bridge the gap between bureaucratic jurisdiction and the biological reality of the forest, ensuring that the next fire season does not result in a further decline of one of Indonesia’s most cherished endemic species.
For now, the village of Balimau serves as a solemn reminder of what is at stake. The silence of the canopy in the wake of the fires is a cost that the region can ill afford to pay again.
