BANJARBARU, SOUTH KALIMANTAN — Amidst the blackened, ash-choked landscape of South Kalimantan, an unusual and poignant sight unfolds. In the shrublands of Liang Anggang District, far from their traditional homes in the high forest canopy, a colony of Eastern honeybees (Apis cerana) has forged a fragile refuge inside the rusted, hollow carcass of an abandoned heavy excavator.

This desperate relocation is a micro-cosmic tragedy reflecting a broader ecological catastrophe. As relentless forest and land fires (kebakaran hutan dan lahan, or karhutla) devastate the province, vulnerable pollinators like wild honeybees are losing their habitats, facing extreme thermal stress, and experiencing a severe disruption in their biological navigation.

Experts warn that the ongoing disappearance and migration of these vital pollinators extend far beyond a localized wildlife quirk. The crisis threatens fundamental ecological balance and casts a long shadow over regional agricultural productivity and future food security.


Main Facts: The Double Blow to Ecosystems and Pollinators

The crisis in South Kalimantan stems from an unrelenting wave of wildfires. Data from the Regional Disaster Management Agency (BPBD) records a staggering 4,926 individual fire incidents between January 1 and October 14, 2026, scorching an estimated 27,202 hectares of land.

The fires have consumed not only dense vegetation, peatlands, and wildlife habitats, but also targeted the invisible engines of ecological reproduction: pollinators.

  • Unnatural Habitation: Deprived of towering trees that once offered shelter 50 meters away, local Apis cerana colonies have resorted to nesting inside industrial scrap metal.
  • Navigational Disruption: Thick haze and particulate matter obstruct the sky, blinding insects that rely on polarized light patterns to navigate.
  • Nutritional Deficit: Extreme drought has decimated floral resources. With blooming plants restricted to resilient weeds like sensitive plants (Mimosa pudica L.), bees must fly exhaustive distances for dwindling drops of nectar and water.
  • Regional Haze Crisis: The environmental degradation is not confined to Indonesia. The ASEAN Specialised Meteorological Centre (ASMC) has maintained its highest alert level (Alert Level 3) for the southern ASEAN region due to transboundary smoke blanketing neighboring Sarawak, Peninsular Malaysia, and Singapore.

Chronology of a Crisis: From Parched Earth to Desperate Migration

The plight of South Kalimantan’s honeybees is deeply intertwined with a severe, prolonged dry spell that has gripped the region throughout 2026.

The Early Signs of Distress

Local residents first noticed behavioral anomalies among the bees roughly three months ago. Fauzan, a resident of Liang Anggang, recalled that the honeybees previously inhabited sturdy trees nearby. However, suffocated by dense smoke and scorching thermal waves, the colonies began their forced exodus.

The Hunters’ Observation

Husni Naparin and Ismu, wild honey hunters from the local collective Madu Hutan Kaum, tracked the flight paths of the bees from the main road to the rusting excavator. Peering through cracks in the metal casing, they discovered multi-layered combs packed with rich honey.

Despite the bounty, the hunters made a conscious conservation choice. "We decided not to harvest," Naparin stated. "We closed the metal flap back up so they can seek shelter, hoping the surviving colony can multiply when the rainy season arrives."

High-Altitude Retreat

Ismu noted that other colonies are fleeing upward, seeking refuge in cooler, relatively pristine environments such as the craggy, steep cliffs of the Meratus Mountains, roughly 102 kilometers from the provincial capital. "They are inhabiting stone cliffs now, likely because the positions are cooler there," he observed.

Supporting Data: Extreme Drought and Air Quality Collapse

The desperation of the honeybees mirrors the severity of South Kalimantan’s meteorological emergency.

Unprecedented Dry Spells

According to the Meteorology, Climatology, and Geophysical Agency (BMKG), South Kalimantan remains under an emergency alert for karhutla. Klaus Johannes Apoh Damanik, Coordinator and Head of the Class I Climatology Station in South Kalimantan, confirmed that rainfall has remained critically low.

BMKG statistics highlight a staggering absence of rain across multiple districts, crossing the 60-day threshold by mid-October 2026:

  • Tamban (Barito Kuala): 118 days without rain.
  • Jorong & Pelaihari (Tanah Laut): 113 days.
  • Panyipatan (Tanah Laut): 112 days.
  • Sungai Loban (Tanah Bumbu) & Kertak Hanyar (Banjar): 111 days.
  • Wanaraya (Barito Kuala) & Landasan Ulin (Banjarbaru): 108 days.
  • Batu Ampar & Tabunganen: 104 days.

Hazardous Air Quality

BMKG air quality monitoring on October 14 revealed that particulate matter (PM2.5) concentrations reached a hazardous peak of 353.8 micrograms per cubic meter at 07.00 WITA. The air quality index hovered between "unhealthy" and "hazardous" throughout the early morning hours, creating conditions toxic to both human respiration and flying insects.


Official Responses and Scientific Perspectives

Scientists and academic researchers have sounded the alarm regarding the catastrophic implications of the wildfires on insect populations and agricultural systems.

Entomological Impact

Ramadhani Eka Putra, an entomologist from the Bandung Institute of Technology (ITB), explained the direct mechanical and biological impacts of wildfires on insects.

"The fires directly destroy nests and floral sources," Ramadhani noted. High ambient temperatures can cause direct mortality, while smoke particles contaminate stored honey reserves. Furthermore, thick smoke obscures the polarized light patterns in the sky that insects utilize as a natural compass, severely impairing their foraging navigation.

The Pollination Crisis

Dr. Trisnu Satriadi, a senior researcher specializing in Non-Timber Forest Products (NTFPs), specifically honeybees and meliponiculture (stingless bee farming) at the Faculty of Forestry, Lambung Mangkurat University (ULM), emphasized that the loss of pollinators cascades upward into human food systems.

"One of the primary functions of bees is as a polinator—helping pollinate plant flowers. Therefore, if there are no bees, the pollination process will occur much more slowly," Trisnu warned.

He explained that crops dependent on insect pollination will suffer reduced fruit and seed set rates. If pollinator populations decline en masse, agricultural productivity will plummet.

"Because of disruptions like karhutla or the loss of food sources, bees will migrate to safer places with abundant food," Trisnu said. However, he cautioned that this migration is a gamble. If destination habitats remain degraded, the bees cannot return, and prolonged vegetation recovery times will dictate whether these populations can ever bounce back.


Implications: A Looming Threat to Regional Food Security

While public discourse surrounding karhutla rightly centers on human health, economic losses, and immediate firefighting efforts, the ecological toll on micro-fauna introduces an invisible, long-term threat.

  1. Agricultural Vulnerability: South Kalimantan relies heavily on horticulture, fruit orchards, and diverse crop farming. The collapse of wild pollinator populations risks a structural drop in crop yields, threatening provincial and national food security in the coming years.
  2. Ecosystem Regeneration Failure: Plant species that rely exclusively on biotic pollination may fail to reproduce. This introduces a feedback loop: degraded forests fail to regenerate, reducing floral resources further and permanently locking out displaced wildlife.
  3. Delayed Recovery: With BMKG predicting that normal rainfall will not fully establish until mid-to-late November and December 2026, the scorched earth of South Kalimantan will remain a hostile environment for weeks to come.

As long as the charred skeletal remains of forests and heavy machinery serve as the primary fallback shelters for displaced honeybees, South Kalimantan’s silent crisis serves as a stark warning: when the wild burns, the foundations of life unravel from the bottom up.
