Welcome to Oaks of the Americas
The genus Quercus (Fagaceae) is an ecologically important component of forest and perennial ecosystems throughout the northern hemisphere, with approximately 415 species worldwide and approximately 255 in the New World alone. All of the New World oak species form a single clade comprised of three distinct lineages, sections Lobatae (red or black oaks), Quercus (white oaks), and Protobalanus (golden-cup oaks). The Oaks of the Americas Life Desk is focused on the diversity of these three clades. If you have questions about this site, please contact Andrew Hipp (The Morton Arboretum).
