A sphere encompasses ideas relevant to restoration and the people working within similar areas of influence or expertise. Increased capacity within a sphere and a higher degree of coalescing among spheres predict a greater probability of successful restoration. We illustrate this with <italic>Castanea dentata</italic>, a foundation forest tree in North America that was annihilated by an introduced pathogen; the species is a model that effectively merges biotechnology, reintroduction biology, and restoration ecology. Because of <italic>C. dentata</italic>'s ecological and social importance, scientists have aggressively pursued blight resistance through various approaches. We summarize recent advancements in tree breeding and biotechnology that have emerged from <italic>C. dentata</italic> research, and describe their potential to bring new tools to bear on socio‐ecological restoration problems. Successful reintroduction of <italic>C. dentata</italic> will also depend upon an enhanced understanding of its ecology within contemporary forests. We identify a critical need for a deeper understanding of societal influences that may affect setting and achieving realistic restoration goals. <italic>Castanea dentata</italic> may serve as an important model to inform reintroduction of threatened plant species in general and foundation forest trees in particular.</p> </sec> </abstract>
