The IOS is pleased to announce our next virtual event, again co-hosted with the Global Conservation Consortium for Oak (GCCO), which will take place over Zoom at 10 am US Central Time on February 19, 2025

In this webinar we will first hear from Cecilia Alfonso Corrado, who will present a talk entitled “Population structure and regeneration of Quercus macdougallii throughout its distribution range in Sierra Juárez, Oaxaca. What is happening with its regeneration?” The presentation will cover work funded by an IOS Oak Conservation and Research Grant.

(You can learn more about Polly Hill Arboretum in articles in the latest International Dendrology Society Yearbook here and in the IOS Journal here.) Following the presentations there will be Q&A.
