Magnolia is a globally diverse, iconic and threatened tree genus. Species of the group are ecologically, economically and culturally important throughout their ranges in North and South America and Asia. Common threats and challenges to conservation mean collaborative conservation planning and action are essential for this group. As lead institution of the Global Conservation Consortium for Magnolia, Atlanta Botanical garden has conducted a global conservation gap analysis of Magnolia adapted from the methodologies used for native US tree groups including Oaks, Juglans, Pinus and Taxus. This work is completed in collaboration with Botanic Gardens Conservation International and with support from the USDA Forest Service, the Institute of Museum and Library Services, Fondation Franklinia and Magnolia Society International.
This publication presents a summary review of the ex situ and in situ conservation status of 336 Magnolia species. Using information from global databases such as BGCIs PlantSearch and a survey of the global botanic garden and conservation community this analysis aims to provide information to organizations working on Magnolia conservation and encourage next steps for collaborative conservation of the world’s Magnolia species.
