Ancient DNA reveals systemic collapse in California’s black abalone: Indigenous stewardship and colonial extraction as intertwined forces

Indigenous coastal peoples like the Chumash, Tongva, and Pomo managed abalone through sophisticated systems of rotational harvesting, sacred site protection, and intergenerational knowledge transfer, maintaining populations for millennia. Their stewardship was disrupted by Spanish missions (1769–1821), which forced relocation inland and severed ecological relationships, followed by U.S. land privatization that criminalized traditional practices. Ancient DNA studies now confirm that pre-colonial abalone populations had higher genetic diversity, directly linking Indigenous management to ecological resilience.
The black abalone’s collapse is not merely a biological crisis but a symptom of settler-colonial land theft and the erasure of Indigenous governance systems that sustained marine ecosystems for millennia.
Ancient DNA confirms what Indigenous communities have long known: pre-colonial abalone populations thrived under reciprocal stewardship, while commercial extraction and land privatization created the conditions for collapse. Yet Western conservation narratives frame the solution as a technical fix—hatcheries and genetic rescue—while marginalizing the very communities whose knowledge and land rights are essential for recovery. The irony is stark: the same institutions that disrupted these relationships now claim to be their saviors, a paradox that demands not just ecological restoration but the restitution of Indigenous sovereignty. True recovery requires dismantling the power structures that produced this crisis, centering Indigenous co-management, and integrating cultural revitalization with scientific innovation. The path forward is clear: land repatriation, kelp forest restoration, and policy reform must be led by those who have stewarded the abalone—and the sea—for generations.
