Northern Arizona University: AI sheds light on California redwoods and fog

Researchers at Northern Arizona University are using AI to analyze California’s iconic redwood forests and the coastal fog that envelops them.
Northern Arizona University researchers have unveiled a machine‑learning system that can read fog patterns from photographs of California’s iconic coast redwood forests. The model, built by a faculty member at NAU, automatically identifies the thickness, extent and timing of the coastal fog that cloaks the trees in a “mysterious gray shroud.” By turning visual data into quantitative metrics, the tool gives scientists and conservation partners a new way to track a climate‑sensitive resource that sustains the redwoods’ towering growth.
The development matters because fog is a critical water source for the redwoods, especially during the dry summer months. Climate change is projected to shrink the fog belt along the northern California coast, threatening the health of these national‑treasure ecosystems. Traditional monitoring relies on sparse weather stations and labor‑intensive field observations; the AI approach can process large volumes of imagery from drones, satellite passes or citizen‑science photos, delivering near‑real‑time insight into fog dynamics across vast tracts of forest.
Looking ahead, the research team plans to expand the model’s coverage and integrate its outputs with forest‑management platforms. Partnerships with state agencies and nonprofit groups could enable early‑warning alerts for drought stress, guiding water‑allocation decisions and restoration efforts. As the technology matures, it may also be adapted to other fog‑dependent ecosystems worldwide, offering a scalable template for AI‑driven climate‑impact monitoring. The project underscores how generative‑AI tools, now a focus of university policy discussions, can move beyond classroom experiments to address pressing environmental challenges.
