But oaks, deeply rooted in mythos and prized for their strength, are now in peril.

The report, which details the most current conservation status of all 430 species of oaks (Quercus), is the result of five years of research by more than a hundred researchers around the globe. “[T]hey are found in nearly every ecosystem on Earth: from deserts to coastal shores and lowlands, from high mountain tops to river valleys, cloud forests, alluvial plains, prairie grasslands, and tropical jungles,” Béatrice Chassé, editor of International Oaks, writes in the introduction to the report. “And yet, in spite of their extraordinary evolutionary and ecological success that spans fifty-six million years, today many of them have dubious futures.” The endangered Quercus bambusifolia, or bamboo-leaf oak, is native to China and Vietnam.
