GCCO Newsletter Published

GCCO

The Global Conservation Consortium for Oak (GCCO) sent out their first quarterly newsletter in late July. The newsletter provides updates on current GCCO activities and shares funding opportunities, publications, and upcoming events. This first issue covers the GCCO US region kick-off meeting that was held online on May 28–29, as well as, sub-regional updates from institutions in the Eastern U.S., Texas and the Southwest, and Western U.S.  You can view the newsletter here.

The GCCO was launched in December 2019; led by The Morton Arboretum, in partnership with Botanic Gardens Conservation International (BGCI), the GCCO aims to mobilize a network of institutions and experts to work collaboratively in order to develop and implement a comprehensive conservation strategy that prevents the extinction of the world’s oak species. It was formed to deliver integrated conservation of oak species through practical ex-situ (in cultivation) and in-situ (in the wild) conservation and to disseminate species recovery knowledge.  For more information, visit the GCCO webpage here.
