International Oak Society Conferences are unique opportunities to talk, learn, and laugh with oak enthusiasts that hail from vastly different horizons: botanists, geneticists, ecologists, arborists, creators of oak collections, conservationists, nursery operators, taxonomists and students, all passionate about the genus Quercus.
The 11th IOS Conference (2025) will be held in Oaxaca, Oaxaca, Mexico. Mexico has the highest oak diversity of any country in the world, and the IOS is excited to be returning after the memorable 6th IOS Conference held in Puebla in 2009.
