Transboundary haze emerges as persistent threat to regional wildlife
Beyond its well-documented impact on human respiratory health, transboundary haze is causing severe ecological disruptions across Southeast Asia, affecting animal habitats, food chains and breeding cycles. Experts warn the phenomenon poses an escalating long-term risk to biodiversity in the region.

Transboundary haze, which regularly blankets Malaysia and neighbouring countries during the dry season, extends its damaging effects far beyond air quality concerns affecting urban populations. Scientific assessments indicate the persistent smoke clouds disrupt critical ecosystems by degrading natural habitats and limiting visibility-dependent animal behaviours essential for survival and reproduction.
Wildlife populations face compounded pressures as haze reduces food availability across multiple trophic levels. Particulate matter obscures vegetation that herbivores depend upon, while simultaneously disrupting the foraging patterns of predator species. Aquatic ecosystems also suffer as reduced sunlight penetration hampers photosynthesis and alters aquatic food webs that sustain fish populations and other water-dependent animals.
Reproductive cycles across numerous species face disruption due to environmental stress triggered by poor air quality. Many animals rely on specific seasonal conditions and visibility for mating behaviours, nest-building and offspring rearing. The repeated exposure to haze during critical breeding periods threatens population renewal rates and genetic diversity in vulnerable species.
Conservation specialists emphasize that these ecological impacts accumulate over successive haze episodes, creating cascading effects throughout regional ecosystems. The transboundary nature of the problem requires coordinated regional responses to address underlying causes of seasonal smoke generation and develop long-term wildlife protection strategies.
