The Morton Arboretum Guides Ex-Situ Collections of Quercus acerifolia

The Tree Conservation Biology lab at The Morton Arboretum contributed an article to the Kew Millennium Seed Bank Partnership newsletter, Samara. The topic was to summarize our work to document, manage, and improve ex-situ collections of the rare and IUCN Critically Endangered Quercus acerifolia (maple-leaf oak). With partners united by the GCCO, such as Stephens Lake Park Arboretum and the City of Columbia Parks & Recreation Department, including IOS members Mark Coggeshall and Ryan Russell and others, we are helping design genetically representative seed orchards that could produce seed for supplementing wild populations—and ensure a future for this species. You can download the newsletter here.  See page 11.
