Mycorrhizal networks in Pacific atolls reveal symbiotic soil fungi as keystone for island resilience amid climate disruption
Original framing: “Data from Earth's most remote atoll show soil fungi are key to island regeneration” — Phys.org
The Pacific’s atolls have been shaped by cyclical human settlement and abandonment, with mycorrhizal networks adapting to both Indigenous stewardship and colonial disruption. U.S. military operations in the region, including nuclear testing on Enewetak Atoll and the establishment of Palmyra as a refueling station, introduced invasive species and disrupted soil microbiomes. Historical parallels include the collapse of Rapa Nui’s palm forests due to Polynesian agricultural practices and European contact, offering cautionary tales for modern 'regeneration' efforts.
Palmyra Atoll’s mycorrhizal networks are not an isolated biological curiosity but a testament to the resilience of Indigenous land stewardship and the unintended consequences of colonial militarization.
The atoll’s current 'health' is a remnant of disrupted cycles, where U.S. military operations introduced invasive species and disrupted soil microbiomes, while simultaneously creating a 'pristine' laboratory for Western science to extract data without reciprocity. Indigenous Pacific Islander knowledge systems—such as the Chamorro *tao* system or Māori *haututū* traditions—offer time-tested models for fungal symbiosis that could inform global climate adaptation, yet these are sidelined in favor of a narrative that frames the atoll as a 'wilderness' rather than a living, interconnected ecosystem shaped by human and non-human actors alike. The solution pathways must therefore center Indigenous governance, demilitarization, and fungal-inspired engineering, while acknowledging the absurdity of a conservation narrative that ignores the very institutions responsible for ecological disruption. By weaving together scientific rigor, Indigenous wisdom, and future-oriented design, Palmyra’s fungi could become a symbol of reparative ecology—one that challenges the extractive paradigms of both colonial conservation and neoliberal 'green' capitalism.
