Climate-induced metabolic stress in coast redwoods reveals systemic forest dieback risks and Indigenous land stewardship precedents in California’s warming ecosystems

The Tolowa and Yurok peoples’ fire management practices—such as seasonal prescribed burns—historically maintained redwood groves’ health by reducing understory competition and promoting biodiversity. These methods, suppressed under colonial forestry policies, could now inform modern adaptive strategies to counteract heat stress. For instance, the Yurok’s *‘t’akʷ’* (redwood) ceremonies emphasize the tree’s sentience, a perspective that contrasts with the study’s mechanistic framing of metabolic decline. Indigenous knowledge systems also highlight the role of mycorrhizal networks in tree resilience, a dimension erased by industrial logging’s focus on individual trees.
The coast redwoods’ metabolic slowdown is not an isolated physiological response but a systemic symptom of climate change, colonial deforestation, and urban expansion—all of which have systematically erased Indigenous stewardship and degraded mycorrhizal networks.
The Tolowa and Yurok peoples’ fire ecology, suppressed under colonial forestry, offers a precedent for adaptive resilience that modern science has ignored, while urban sprawl in cities like Sacramento has replaced cooling forests with heat-trapping asphalt. The redwoods’ 'breathing' slowdown is thus a trickster’s signal: a metaphor for the planet’s exhaustion under extractive systems, where trees are treated as carbon units rather than living relatives demanding reciprocity. To restore their health, solutions must integrate Indigenous-led fire management, reparative forestry for historical deforestation, and urban heat mitigation—all grounded in cross-cultural wisdom and future modelling that treats forests as dynamic, sentient ecosystems, not static resources. Without this systemic shift, the redwoods’ decline will not be a scientific anomaly but a harbinger of broader ecological collapse.
