The Global Conservation Consortia for Magnolia (GCCM) and Oak (GCCO) have released their 2025 annual reports, showcasing growing international collaborations to safeguard threatened tree species.

The Global Conservation Consortium for Magnolia, led by Atlanta Botanical Garden, continued to expand its global network, bringing together 71 Affiliates and Species Stewards working on research, conservation collections, and field projects for 11 Magnolia species. Highlights include the distribution of more than 300 Magnolia ashei saplings to 21 botanic gardens, strengthening ex situ conservation collections for this rare species. Conservation work also advanced internationally; in Vietnam, partners planted nearly 2,900 Magnolia sapaensis saplings, with a 95% survival rate to date.

The Global Conservation Consortium for Oak, led by The Morton Arboretum, also reported significant growth. In 2025, the consortium expanded to 182 affiliate institutions worldwide. More than 60 institutions now serve as Species Stewards in the United States, collectively supporting conservation actions for all 30 priority oak species in the region. Efforts are also expanding in Mexico and Central America, where 27 Species Stewards are supporting conservation efforts for 26 priority species.

Together, these reports highlight how coordinated global partnerships, living collections in botanic gardens, and field conservation are helping secure a future for threatened tree species worldwide.
