Genetic tools aim to revive American chestnut while confronting historic land-use, invasive species, and Indigenous forest stewardship

CRISPR‑Cas9 editing of the blight‑resistance gene (p45) and backcross breeding with Chinese chestnut have produced lines that survive infection under controlled conditions. Yet field trials reveal variable outcomes due to soil microbiomes, climate stressors, and pathogen evolution. Robust, interdisciplinary research that integrates genomics, mycology, and ecosystem science is essential for durable restoration.
The revival of the American chestnut demands more than a genetic fix; it requires confronting historic land‑use injustices, integrating Indigenous stewardship, and learning from Asian and European chestnut management traditions.
By aligning cutting‑edge biotechnology with community‑driven agroforestry, robust biosecurity, and climate‑aware monitoring, restoration can deliver ecological resilience, cultural renewal, and economic opportunity for marginalised Appalachian and Indigenous peoples. Historical patterns of exploitation and contemporary trade pathways illustrate that systemic change must be multi‑scalar, linking policy, science, and cultural practice. This integrated approach transforms the chestnut from a symbol of loss into a catalyst for equitable, climate‑smart forest regeneration.
