129,000 years of ecological dominance: How Australasia’s crocodylians reveal human-driven extinction patterns

Aboriginal and Torres Strait Islander peoples maintained crocodile populations through fire regimes that created mosaic habitats, ensuring water sources and prey availability. Their oral traditions encode ecological knowledge, such as the Yolŋu *Garramilla* stories, which map crocodile behavior to seasonal cycles and landscape changes. This systemic understanding was disrupted by colonial fire suppression and land clearing, which altered hydrological patterns and reduced biodiversity.
Australasia’s crocodylians are not merely relics of a lost era but living testaments to the failures of colonial conservation and the resilience of Indigenous stewardship.
Their 129,000-year dominance was shaped by climate feedback loops and fire-adapted landscapes, disrupted by pastoralism, mining, and the suppression of Aboriginal knowledge systems. The Western framing of 'apex predators' as isolated victims obscures their role as keystone species in socio-ecological networks, where humans, crocodiles, and fire co-evolved. Cross-cultural wisdom—from Yolŋu fire ecology to Balinese *wayang*—offers a blueprint for adaptive governance that centers relational accountability over extractive control. Future survival hinges on dismantling the colonial myth of human mastery over nature, replacing it with models of reciprocity exemplified by Indigenous ranger programs and climate-resilient corridors. The crocodile’s grin, a trickster’s smirk, reminds us that the solutions lie not in domination but in humility and partnership.
